The bimetal composite wear plate is produced by Qi Shuai wear-resistant equipment is a combination of two different properties of the base plate (Q235, A3 steel plate) and chromium carbide wear-resistant alloy.
The chromium carbide wear-resistant alloy is metallurgical combined with the substrate through a special overlay welding process, and a 3-20 mm wear-resistant alloy layer is deposited on the surface of the substrate to form a wear-resistant alloy.
The bimetal composite wear steel plate has a hardness of 58 to 62 HRC.
After cold work processing (rolling, cutting, welding), the bimetal composite wear steel plate is made into various wear-resistant parts.
Bimetal composite wear steel plate has excellent wear resistance, and has the processing performance of low carbon steel such as Q235 (welding, cutting, coiling), and is easy to install.
The wear resistant life is 12-20 times that of ordinary steel plates, and the impact resistance is twice that of ordinary steel plates.
Especially suitable for abrasion in harsh environments. Such as power, metallurgy, coal, mining, cement, dredging and other industries
Processing technology of bimetal composite wear steel plate
Cutting processing: plasma cutting, high-pressure waterjet cutting
Coil processing: Inner coil (wear layer facing inward) curl radius R15 times wall thickness Outer coil (wear layer facing inward) curl radius R30 times wall thickness
Substrate welding: Cr28 wire / electrode, butt welding machine arc welding, try to use a small current and ensure penetration, the remaining height of the weld is greater than 3mm. Each weld shall be inspected by color inspection.
Maximum plate width: 3000 * 1500mm
Wear-resistant alloy performance parameters
Alloy type: Iron-based high chromium alloy Chemical composition:
C: 4 ~ 5% Cr: 20 ~ 30% Si: 0.5-1.5%, Mn: 0.5-2.5%
Installation method of bimetal composite wear steel plate:
Welding: Welding of the substrate of the wear-resistant composite steel plate and other equipment directly, fillet welds on the four sides, and plugs in the middle.
Countersunk head screw holes: Open countersunk head screw holes on the wear-resistant composite steel plate and connect and fix the device with countersunk head studs.
Substrate stud welding: Weld studs or nuts on the substrate of the bimetal composite steel plate, and connect and fix them by bolt equipment.
