Chromium Carbide Plates Production

Chromium carbide plate has been initially popularized and applied.

Some blast furnace water flushing slag pipes and slag ponds of iron smelters are made of chromium carbide plates, which have been used for more than two years without damage.

On the cement production equipment manufactured by cement machinery factory, chromium carbide plate is used as lining plate, and the effect is very good, and its product quality has increased the competitiveness.

The gas plant uses chromium carbide plate to manufacture coke hopper, the service life of steel plate hopper is only one month, the service life of chromium carbide plate hopper is more than two years.

Due to the good performance of chromium carbide plate, it is widely used. However, it is also seen that some enterprise purchasing personnel are not clear how to distinguish the good and bad quality of overlay wear plate.

Then how to quickly judge the quality of the overlay wear plate? It needs to be judged from the following points.

The process of surfacing wear plates

I. Size

The first thing to look at is whether the size of the whole plate meets the specifications. Generally, the plate number, plate size and welding specification will be clearly and accurately marked on the surface of the product.

Secondly, see whether the size of the weld channel is uniform. The width of the weld channel is uneven, the error is more than 5mm generally unqualified products, except for the last weld channel of the welding gun.

In addition, welding specifications, must meet the requirements, otherwise it is unqualified products.

II. Thickness and flatness

Different specifications of the surfacing wear plate have different thickness standards, measuring the middle of the weld channel, measuring five values to take the average. Average thickness tolerance 0 to 0.7mm is the most perfect, thickness tolerance >1mm is generally unqualified products.

III. Surface forming

Surface forming to pay attention to the details of more.

The first observation of whether there are pits (diameter greater than 4mm, depth greater than 2mm dents defined as pits), whether the pit repair. General repair traces, a single pit repair area is best within 20mm * 20mm.

The second to see the weld channel surface to pay attention to whether there is a porosity (wear-resistant layer within the cavity due to poor gas overflow is not filled by the laying molten metal. The weld channel is not well formed (caused by low current or welding wire), arc break and other problems.

Thirdly, we should observe the combination of substrate and wear-resistant layer. Wear-resistant plate large area off, wear-resistant layer and the combination of the substrate a large area of porosity, after welding caused by cracks in the substrate, welding leakage and other problems are generally substandard products.

IV. Hardness and chemical composition

Through naked eye observation and calipers and other tools, we can roughly judge the quality of wear-resistant plate.

The chemistry will be different for different applications and specifications as well as for each company&#;s R&D capability and production process. The hardness (HRC) of conventional wear plates should not be less than 55.

In the eyes of professionals, it is not difficult to purchase overlay wear plates, just focus on the following issues.

1. Understand the basic situation.

The main thing is to know what styles of surfacing wear plates are available on the market, the performance and price of different styles, to provide a basis for purchase.

2. Choose a reliable manufacturer.

Nowadays, there are more manufacturers that provide custom-made surfacing wear plates, and the comprehensive strength of different manufacturers is not the same, which makes the performance of the products different.

3. Choose a good purchase channel.

At present, there are many kinds of purchase channels, such as contacting manufacturers to customize, to the wholesale market to buy. Before choosing the purchase channel, understand the purchase price of each channel, for the same, the same kind of surfacing wear plate, try to choose the purchase channel with lower offer.

Of course, there are many other issues to consider when buying surfacing wear plates, such as paying attention to the quality of the surfacing wear plates. If the quality does not go up, it will certainly affect the service life and use effect. Surfacing wear plates are formed after adding special elements to ordinary steel, such as Si, Mn elements, etc., which can enhance the wear resistance of steel plates. Before purchasing, customers who are in a position to do so can also go on a field trip to the surfacing wear plate manufacturer to understand the manufacturer&#;s production capacity, scale of operation and industry fame.

Can Chromium Carbide Plates have more layers?

When dealing with CCO wear plates, the wide majority of people think that the more layers a particular wear plate has, the better.

Since their main purpose is to absorb friction and abrasion, not letting it reach the part itself, you&#;d think the same, right?

However, that is not true. Having more does not always translate to good or better.

Even if there&#;s just one pass or one layer of chromium carbide wear plate, if it has been welded properly and appropriately, and if the chemistry of the elements and compounds are compatible with one another, it&#;ll be better than a normal and a regular CCO wear plate that has a double pass.

Who Needs Chromium Carbide Plate?

Many industries and business areas feel the need to use chromium carbide overlay wear plates.

The Pulp and Paper industry &#; one of the industries that use CCO wear plates

The Pulp and Paper industry &#; one of the industries that use CCO wear plates

The most common industries that are vocal about their need to use CCO wear plates include the construction or the structural industry, and the heavy earth moving industry.

To cite other industries that need it, they are:

Gas and Oil Industry

The gas & oil industry use wear plates for many different parts and components, including valves, boilers, heat exchangers, compressors, chutes, conveyors, and many more.

Pulp and Paper Industry

For the pulp and paper industry, wear plates are regularly applied and integrated to refiners, pulpers, chippers, cyclone fans, mixing machines, pipelines, etc.

Mining or Coal Mining Industry

With the mining and/or coal mining industry exposed to frequent abrasion and friction, the use of wear plates has been seen as a standard in many different situations.

As a matter of fact, the most common machines/equipment that are installed CCO wear plates on include dumpers, bulldozers, graders, excavators, rotary blades, loaders, and many more!

Apart from those industries, there are other industries that rely on chromium carbide overlay wear plates for the life and the prolonging of their parts/machines.

Can Chromium Carbide Have Paint?

The quick and easy answer to that is no &#; wear plates, especially chromium carbide overlay plates wouldn&#;t have too much of a difference if it has solid paint or not &#; or if the paint is cranked and mixed up.

This probably is the most common misconception that experienced and seasoned workers have when choosing CCO wear plates.

Color shall never be a side of judgment in choosing which CCO plates to buy. As a matter of fact, you might even see hairline cracks, check-cracks, and other thin lines on the CCO plate when you first purchase it.

To be fair, they&#;re completely normal! Seeing a thin-line crack isn&#;t a sign that the CCO plate has been damaged or worn-out; it is, in fact, a natural stress relieving effect that the plates have.

Tips to Choose Chromium Carbide Plate

There are a couple of things you should look for before you purchase chromium carbide overlay wear plate.

As mentioned above, the thickness or the number of passes isn&#;t significant enough if the chemistry is not thought of fully.

That being said, here are the best tips so you&#;ll be able to purchase the best and the highest quality of CCO wear plates.

Bigger Plates are Always Better

While pass thickness isn&#;t much of a big deal, the larger the size of the CCO plate, the better.

Imagine a wear plate that&#;s smaller than the bucket you&#;re trying to cover. Also, if you are going to install it on a loader or an excavator, would a small one fit it? Probably not!

There are manufacturers that produce large-sizes chromium carbide overlay wear plates, while those that just weld two (2) or more small pieces together. You need to make sure that you&#;re purchasing large and wide-sized CCO wear plates for better results.

So, checking on the history, the background, and the overall capability of the manufacturer is important. We&#;ll get to that in a later part of this guide.

Ask For Samples

Most, if not all CCO wear plate manufacturers offer free samples to clients and businesses. These samples are ways to check if the product or the CCO wear plate is fit to the need of the client.

Should they provide a sample, you can do and perform tests and assessments to that particular sample.

But, there are a few chromium carbide wear plate suppliers that do not offer samples; it&#;ll be better to work with a manufacturer that provides free samples.

The Hardness Level Isn&#;t Always Important

Different chromium carbide overlay wear plates have different hardness levels. The hardness would depend on a wide range of factors, such as the heat treatment, the material used, and many more.

On average, the hardness levels of chromium carbide overlay or CCO wear plates are usually around 59 to 64 HRC.

But, the harder the wear plate is, the more brittle and fragile they are. High-level hardness CCO wear plates are prone to cracking, breaking, and splitting.

How is Hardness Measured?

To add extra information and knowledge to this, here&#;s how hardness is measured.

Measuring the hardness of a particular item can be done in many different ways. However, the most common ones are the Brinell and the Rockwell scale.

Typically, measuring the hardness of CCO wear plates is done via the Rockwell (HRC) or the Hardness Rockwell C.

59 HRC, when converted to Brinell, is 590 HB. 64 HRC, on the other hand, is measured ad 668 HB.

Contact us to discuss your requirements of chrome carbide overlay supplier. Our experienced sales team can help you identify the options that best suit your needs.

The higher the number, the harder the particular item or CCO wear plate is. So, it might seem typical to see the regular or the average hardness level of chromium carbide overlay wear plate is at 59 to 64 HRC.

However, different manufacturers, use different materials and products to produce and to manufacture CCO wear plates &#; they&#;re not all the same.

There are manufacturers that produce malleable CCO wear plates, while there are those that manufacture CCO wear plates that have HRC levels over 72.

Service Temperature

This property measures the capacity of the CCO wear plate to be worked on under temperatures.

If we put it in average, the maximum service temperature of these plates is at 600 to 650 degrees Celsius or 1,100 to 1,200.

Impact

When it comes to the impact, this is the capability of a CCO wear plate to be able to resist and absorb impact.

Abrasion

The amount of abrasion resistance of a particular chromium carbide overlay plate depends on the composition of it.

Abrasion refers to the wearing out of the surface such as scratching, rubbing, and marring.

Service Life/Life Expectancy

Lastly, the service life or the lifespan of the CCO wear plate is relevant and significant as well.

Although the life expectancy would still depend on usage, as well as other external influences, manufacturers give the expected service life of their CCO wear plates for clients to have a general threshold of until when they&#;re effective.

Look Into the Manufacturer/Supplier&#;s Capability

While these things are a lot to digest, the best thing to do is to still look into the legitimacy and the experience of the manufacturer you&#;ll be working with.

The quality and the overall effectiveness of chromium carbide wear plates will, of course, depend on the one who made it.

If the chromium carbide wear plate manufacturer isn&#;t reputable or if they&#;re known to provide CCO wear plates that are not-up-to-standard, then you should already think twice about working with them.  

To illustrate further, there are newer manufacturers of wear plates that skip heat treatment because they think it&#;s not a collaborative factor in the strength and quality of the material. These manufacturers are obviously inexperienced and are not used to other procedures in which wear plates are used for.

To successfully check the background or the history of a manufacturer, you can try the following:

Check Reviews

While the reviews you see online aren&#;t much impacting, the reviews that real clients they had could be everything you need to decide.

If you see a line of reviews that is 100% positive &#; then, the chances of that manufacturer being world-class is higher, you can immediately come up with a conclusion that they&#;re easy-to-work-with.

Speak to Previous Clients

Another thing you can do is to find previous clients of that particular manufacturer. Try communicating with those clients and ask about the service and the products the manufacturer is offering.

Were they up to the expectations of the client? Or were there a lot of challenges towards completion?

Check Their Manufacturing Plant/Office

Lastly, the condition or the ambience of the manufacturing plant reflects directly on the quality of service the manufacturer has.

The plant or workspace reflects the quality of products and services

The plant or workspace reflects the quality of products and services

Since the rise of technology, many suppliers opened a virtual setting of their manufacturing plants and offices.

This paved way for clients to be able to &#;visit&#; their factories without being physically there. Oftentimes, the best manufacturers would offer a virtual tour of their factory.

They wouldn&#;t be shy to let their factories and their manufacturing processes out.
