| High manganese steel is strong and the surface can be hardened. But the material used in the manufacture of ball mill liner is easy to produce plastic deformation, cut off the set screw bolt, a collapsing accident, and due to the use of surface in the process of work hardening do not show yarrow, can't exert anti-wear potential of high manganese steel. As the replacement of the high manganese steel lining plate in the carbon in the chromium complex alloy steel plate, the matrix organization in martensite is given priority to, have higher initial hardness, but smaller carbide content of high hardness, anti-wear performance is still limited, its service life than high manganese steel liner doubled or so. Double metal wear-resisting lining board face as high chromium alloy cast iron, the microstructure of eutectic carbide M7C3 + secondary carbides + martensite + retained austenite, has the very high hardness (HRC 58) or higher, also to have enough toughness. Not working for low carbon steel, the hot composite technology, make high chromium alloy cast iron and steel fusion as a whole, overall resilience of double metal wear-resisting backing board Is better, properly solves the problem of hard and tough it too. |
