High temperature wear-resistant alloy steel is produced by smelting and other processes using the following components and weight percentage of raw materials: 77.5 ~ 79% scrap steel, 18.3 ~ 20 7% high carbon ferrochrome, 0.67 ~ 1.0% ferro molybdenum, 0.33 ~ 0.5% iron vanadium, appropriate amount of silicon, manganese deoxidizer, 0.05 ~ 0.1% ferrotitanium, 0.02 ~ 0.05% zirconium, 0.6 ~ 1.2% aluminum and 0.12 ~ 0.5% rare earth elements. The alloy steel produced in this way contains 1.45 ~ 1.70% carbon, 11.0 ~ 12.5% chromium, 0.4 ~ 0.6% molybdenum, 0.15 ~ 0.30% vanadium, 0.02 ~ 0.05% titanium, 0.02 ~ 0.05% zirconium, 0.6 ~ 1.2% aluminum and 0.05 ~ 0.15% rare earth elements.
High temperature wear-resisting alloy steel can significantly change the thermal stability and wear-resisting properties of alloy steel by multi-element and small amount alloying, melt purification, heat treatment strengthening and microstructure refinement, and make the crystal thinning, carbide fine and uniform distribution, but also has excellent comprehensive properties in hardness, tensile strength, impact toughness, thermal erosion rate, friction and wear loss, etc. Therefore, it is the ideal material for manufacturing high temperature wear-resistant guide wheel and roll in iron and steel metallurgy industry.
Wear-resistant ball mill lining plate includes wear-resistant lining plate base plate, wear-resistant lining plate base plate is arranged on the top of the installation thread hole, wear-resistant lining plate base plate at the bottom is fixed connected with a stress reduction plate, stress reduction plate at the bottom is connected with a hard reinforcement plate, wear-resistant lining plate base plate is arranged on the top of the groove, groove is symmetrically arranged on both sides of the installation thread hole, The bottom of the inner wall of each groove is fixedly connected with a damping column, the top of the damping column is fixedly connected with a rubber pad, and the outer wall of the rubber pad is sliding connected with the inner wall of the groove.
The lining plate of the ball mill can reduce the noise generated by the wear-resistant lining plate substrate in the grinding process of ore through the sound absorbing board, positioning bar, installation groove, stress reduction plate, rubber pad, shock absorber and hard strengthening plate through the sound absorbing board, so as to avoid the noise caused by pollution to the surrounding environment, and positioning bar can avoid the sound absorbing board shaking. The vibration frequency between the wear-resistant lining plate and the mine ball mill can be reduced by the rubber pad, so as to reduce the vibration generated by the wear-resistant lining plate
