Chromium Carbide Wear Plate

Shandong Qishuai Wear-Resistant Equipment Co., Ltd.'s Chromium Carbide Wear Plate are composed of a high-hardness wear-resistant layer bonded to a highly ductile substrate. There is relatively large amount of hard chromium carbide particles in the wear resistant layer. They are uniformly dispersed in the alloy layer to form a powerful anti-wear layer. The chromium carbide has very high hardness and antichemical diffusion performance. It can resists the erosion, friction and impact of material and greatly improves the service life of equipment. The substrate adopts high quality low carbon steel or low alloy steel. The plates have good strength and toughness to ensure the stable operation in various harsh environment.

Exceptional Wear Resistance

Why do thewear plates made by Shandong Qishuai Wear Resistant Equipment Co., Ltd. have excellent wear resistance?

Chromium carbide wear resistance comes from its chemical composition and microstructure. The volume fraction of hard chromium carbide phases in the wear-resistant layer of chromium carbide wear plates can reach more than 50%. The hardness of chromium carbide phases is very high. Microhardness is HV1400–1800, which far exceeds the hardness of ordinary steel plates and most commonly used abrasive media.

It will take a short time for the crusher liners forged by ordinary steel plate to be worn away and replaced, thereby increasing the equipment maintenance cost and reducing the production efficiency.

The wear resistance of crusher liners formed by Shandong Qishuai’s wear plate is 10–30 times that of ordinary steel plate, which will take a short time to be worn away and replaced.

We can know more about the excellent wear resistance of the wear plates through wear tests performed by professionals.

It is evident from the chart that when the wear time and operating conditions are the same, the wear film of common steel plates can be 10 times thicker than that of chromium carbide wear-resisting plates. This has proven that chromium carbide wear-resisting plates have very strong wear resistance and can offer equipment in industry a longer term of service. Consequently, they effectively extend equipment service life while reducing maintenance and replacement costs.

Excellent Impact Resistance

The wear plates have excellent wear resistance as well as impact resistance. Because of the 'hard surface and tough substrate' design. The wear layer of chromium carbide alloy is very hard and can withstand the wear of base material. The substrate uses low carbon or low alloy steel with good toughness, such as Q235, Q345 etc. When impacted, the substrate can absorb the impact energy and avoid the wear layer being impacted by impact and falling off.

This robust impact resistance enables chromium carbide wear plates to perform exceptionally well across various high-impact industrial settings. They provide a strong guarantee for stable equipment operation, minimising downtime caused by equipment damage and enhancing production efficiency.

High-Temperature Resistance

In numerous industrial production processes, equipment must operate within high-temperature environments, imposing stringent demands on materials' resistance to elevated temperatures. The wear plates of Shandong Qishuai Wear Resistant Equipment Co., Ltd. have good performance stability at high temperatures. The alloy carbides have high temperature stability and are highly hard and wear-resistant.

Typically, thewear plates can function normally at temperatures up to 500°C. For specialised high-temperature applications, incorporating alloying elements such as vanadium and molybdenum into the alloy layer further enhances heat resistance, enabling the plates to withstand high-temperature abrasion up to 800°C. In metallurgical furnaces and kilns, where temperatures frequently reach 600–800°C, linings constructed from ordinary steel plates rapidly deteriorate due to thermal oxidation and wear. On the other side, the furnace linings constructed with Shandong Qishuai Chromium Carbide Wear Plate maintain a stable performance over periods in the high temperature environment effectively extends the service life of the furnace and lowers the ratio of maintaining and purchasing furnace.The following chart shows the hardness change of theWear Plates at different temperatures.

As can be seen from the chart, even at temperatures as high as 800°C, the Wear Plate maintain a certain degree of hardness. This ensures their wear resistance and structural stability under high-temperature operating conditions, thereby meeting the stringent requirements for high-temperature wear-resistant materials in industrial production.

Frequently Asked Questions

What should I pay attention when chromium carbide wear plates installation?

When Before installing the wear plates, please make sure that the mounting surface should be flat, clean and free from oil, rust or other impurities to ensure the quality of welding or adhesive bonding. Choosing the electrode with compatible chemical composition for welded mounting. Preheating the work piece before welding to avoid the cracking of the heat affected zone. Using segmented and layered welding method. Strictly controlling the welding current and welding speed to avoid overheating. Carrying out controlled cooling after welding.

How to maintain and care for chromium carbide wear plates?

Clean the  wear plates regularly with high pressure water jet or soft brush with neutral washing agent. It is forbidden to clean with highly corrosive cleaning agent which may damage the wear resistant layer.

Avoid that the wear plates are loaded over the limit during the operation. Choose the equipment and process according to the bearing capacity of the wear plates. That is to say, the material inflow velocity and impact force during the operation should be within the safe range. Install the monitoring sensor to get the operation status and usage of the wear plates in real time and analyze the data to predict the wear plate wear pattern and handle the maintenance in time in case of time. If there is any wear, cracking or other phenomenon, it should be repaired and replaced in time.

How long is the service life of the wear plates?

The service life of the wear plates is related to the working environment (material hardness, impact degree, temperature, humidity, etc.), operation (overload, impact times, etc.) and maintenance. Generally, under the condition of moderate wear, the service life is about 5-10 times of common steel plate. Even in the case of severe wear and impact, the multiple life is also about 3-5 times of common steel plate. Its service life can be extended by proper maintenance and correct usage.
