chromium carbide overlay plate hardfacing technology in cement and power plant

Chromium carbide overlay plate hardfacing technology is widely used in cement and power plant equipment and machinery, and has a higher requirement on welding equipment and raw welding materials.

Hardfacing process parameters including welding bead width, welding speed, diameter, volume, surfacing welding current, arc voltage, temperature between layers, the wire extension length and angle, hardness, thickness deviation, allowed crack depth and length, edge surfacing allowance and work-piece temperature etc.

Wear parts wear resistance is determined by the material properties, which comprises metal material chemical composition, microstructure, strength, toughness, plasticity and brittleness, wherein the surface hardness of metallic materials is particularly important for abrasion resistance performance, also it is a matter of great customers interest. In addition, the microstructure of matrix material is also very important. Besides hardness, appropriate surfacing process is vitally important to improve bimetallic plate working performance, so ad to obtain the optimal carbides hardness, size and distribution.

Zhangjiagang YaoYu Wear Resistant Materials Company hardfacing machine welding system runs stably and has a high production efficiency, we can supply 20pcs 10mm chrome carbide overlay plate per day, total 90 square meters. The whole open arc welding process has very good welding characteristics and good heat treatment property , and can greatly reduce the thermal effect of inter-pass and spots compared with the traditional submerged arc welding. Total chromium carbide overlay plate sheet has smooth and clean hardfacing surface, without pits or spots, and has uniform welding cracks on the surface.
