description

low chromium alloyed casting iron in general refers to the alloy white iron with the chromium content at 1 3 the carbon content at 2.1 2.8. its distinctive features is that the m7c3 type eutectic carbide micro hardness is hv1300 1800. the eutectic carbide is distributed on the base martensitethe most hard metal matrix organization in discontinuous network and isolation which reduces the fragmentation of the matrix effect. as a result the low chromium ball mill liner has high strength strong toughness and good wear resistance performance which represents the higher level of metal wear resistant materials.

processing technique

intermediate frequency furnace smelting high-quality steel scrap and chromium alloy etc.

constant temperature casting process ensuring the quality no sonim no pore etc.

oil-immersed heat treatment and annealing process changing the internal organizational structure lowering the breakage and improving the performance.

matter test after the furnace test semi-finished products and end products inspection was done by advanced spectrometer and durometer.
