The composite wear-resistant steel plate is a high-temperature method such as spray welding, surfacing welding or laser plasma cladding, etc., to fuse the high-hardness wear-resistant material with the substrate to achieve metallurgical bonding, and the strength can reach more than 300 MPa, of which the substrate can be Choose according to your needs, such as commonly used Q235 or stainless steel, etc. The main difference is the corrosion or temperature of the working conditions. If there is corrosiveness, you need to choose stainless steel as the substrate. The same is true for high temperature. When there is a high temperature working condition, ordinary carbon steel It can no longer meet the requirements, and it is necessary to choose stainless steel, of course, the cost will be higher. The alloy wear-resistant material is mainly based on chromium carbide, and the content of nickel, molybdenum and tungsten can be adjusted. That is to say, the customer proposes the alloy content or we need to add nickel according to the working conditions, such as high temperature needs to add nickel, impact needs to add molybdenum, hardness add tungsten, etc. .
With the continuous popularization of composite wear-resistant steel plates in recent years, it has become one of the materials with the largest consumption of wear-resistant plates in the industry, from large coal bunkers in coal mines to small coal drop pipes; from cement clinker silos to fans Blades; from broken glass warehouses in glass factories to production glass line skateboards, they are everywhere, and they are our good helpers to solve industrial wear and tear. The relevant technical parameters are introduced below.

Instructions for use of composite wear-resistant steel plate:
1. Generally, the base material of composite wear-resistant steel plate is low carbon steel or low carbon low alloy steel, thickness: 6-40mm; thickness of surfacing layer: 4mm. Users can choose according to their own usage or put forward special requirements according to their own needs.
2. Users who purchase standard composite wear-resistant steel plates can use the following simple processing as needed:
1) Cutting
According to the shape and size requirements, the composite wear-resistant steel plate can be cut into the required shape and size by the plasma arc cutting method.
2) Bend
The composite wear-resistant steel plate can be bent into an arc shape or made into cone and barrel parts by means of a press or a spheronizing machine.
3) Welding
The base material of the composite wear-resistant steel plate is a steel plate with good weldability. The two clad plates can be spliced by welding, or the clad plates can be welded to other steel structures.
4) Plug welding
Plasma arc or arc gouging can be used to open holes on the composite wear-resistant steel plate and connect with other steel structural parts by plug welding.
5) Bolt fixing
During production, bolt holes can be reserved according to the requirements of the drawings, and the bolts can be connected to other workpieces through countersunk bolts; the bolts can also be welded to the base material of the composite wear-resistant steel plate by flash welding or fusion welding, and then connected to other workpieces. connected.
