What are the performance characteristics of chromium carbide wear-resistant composite steel plate?

Chromium carbide composite wear-resistant steel plate is a kind of wear-resistant plate. In order to further improve its performance, the material, process and equipment are compared and analyzed, and the main factors affecting the hardness and load of chromium carbide composite wear-resistant steel plate are obtained, so what are the performance characteristics of chromium carbide wear-resistant composite steel plate?

What are the performance characteristics of chromium carbide wear-resistant composite steel plate?

1. A hypereutectic alloy composite laminate consisting of a chromium carbide alloy fused to a suitable steel substrate by electric arc. Cemented carbide with high chromium carbide content makes the wear-resistant composite steel plate suitable for harsh wear environments.

2. The hardness of the wear-resistant composite steel plate is composed of the hardness of the hard chromium carbide alloy (Vickers hardness 1750V) and the hardness of the strong austenitic composite matrix. The macro hardness of the composite plate is 55-67 Hrc, the specific value depends on the thickness of the composite layer.

3. The surface of the wear-resistant composite steel plate is very smooth and flat, so that the surface friction coefficient is very low. This property makes it an ideal material for vertical levitation and erosion.

4. The wear-resistant composite steel plate has a very uniform seepage layer, the binding force between the composite layer and the matrix is very large, and the seepage diffusion is very small.

5. Generally, medium and low carbon steel is used as the matrix. Easy to shape, especially for complex shapes. And has a unique damping capacity. According to the customer's special order, the wear-resistant composite steel plate can also provide composite plates with different material substrates. various alloy structures

What is the source and practical application of the excellent performance of chromium carbide composite wear-resistant steel plate?

1. At the same time, the application of materials in pellet drying kiln is realized. Casting is the main manufacturing process, electrolytic copper, pure tin, pure nickel, brass, lead, rare earth is the main raw material. The mechanical properties and friction properties of the formed chromium carbide composite wear-resistant steel plate were studied, and the results showed that the anti-friction phase and refined microstructure in the alloy played a very significant role in improving the wear resistance of the chromium carbide composite wear-resistant steel plate. Therefore, in order to improve the performance of chromium carbide composite wear-resistant steel plate, only the right amount of tin, nickel and rare earth can be added. It is necessary to strengthen the matrix of the wear plate and improve its performance.

2. This is also the reason why the chromium carbide composite wear-resistant steel plate has the characteristics of high strength, high hardness, workability, wear resistance and corrosion resistance. It is also the key to the wide application of materials in various industries. The chromium carbide wear-resistant composite steel plate has excellent performance and can be used in pellet drying kilns, which plays a positive role in improving equipment performance. As the key equipment of pellet, the drying kiln should be kept in operation and a large amount of iron ore powder should be stirred. Coupled with the high temperature erosion of the gas, the operating conditions of the equipment are very harsh.

3. In this case, the choice of equipment and materials is very important. After using for a period of time, the original liner will be severely worn and scrapped, which will bring great economic losses to the enterprise. Later, the pellet drying kiln was lined with chromium carbide wear-resistant composite steel plate, and the effect was obviously different. Practice has proved that the liner made of chromium carbide wear-resistant composite steel plate is still intact after long-term use, which greatly saves costs and reduces losses for enterprises. In addition, chromium carbide wear-resistant composite steel plate in the electrical industry, transportation, light industry, building materials and other fields have also achieved remarkable results.
