Wear-resistant composite lining plate is an alloy wear-resistant layer composed mainly of Cr7C3 carbide with a volume fraction of more than 50%, which is surfacing welded on ordinary steel plates, heat-resistant steel plates, and stainless steel plates.
Wear-resistant composite lining plates have the properties of high wear resistance, impact resistance, deformability and weldability. They can be directly processed by curling deformation, cutting and drilling like steel plates, and can be processed into engineering parts to meet the wear requirements of industrial and mining applications.
When the grindability of the material is medium (the Bond work index of slag is 20, the Bond work index of raw material is 10, the Hastelloy index of coal is 75 or the ton consumption is 3g/t), the slag vertical grinding wear-resistant parts after surfacing are normal The running time reaches 1800 hours to 2000 hours, the running time of coal vertical mill wear-resistant parts reaches more than 7000 hours, the running time of raw material vertical grinding wear-resistant parts reaches more than 7000 hours, the running time of cement clinker vertical grinding wear-resistant parts reaches more than 2500 hours . When the running time of the squeeze roller reaches more than 4000 hours (after online surfacing) to 8000 hours (after offline surfacing), it can be considered that the wear-resistant parts after surfacing have reached the expected wear performance requirements.
Wear-resistant composite lining plate manufacturers require that for vertical wear-resistant wear parts whose casting base material is high chromium cast iron or nickel hard IV, the surfacing layer should not fall off within 3 months after the surfacing remanufacturing is completed and put into operation.
