Products Description
Products Description:
High Chrome alloyed casting iron in general refers to the alloy white iron with the chromium content at 12%~26%, the carbon content at 2.0%~3.6%. Its distinctive features is that the M7C3 type eutectic carbide micro hardness is HV1300~1800. The eutectic carbide is distributed on the base, martensite(the most hard metal matrix organization), in discontinuous network and isolation, which reduces the fragmentation of the matrix effect. As a result, the high chromium mill liner has high strength, strong toughness and good wear resistance features , which is widely used at Mining ,Cement and power industry .
White iron liner is recommended to be using at low impact working condition such as :
1. Belt converyor liner for Miing industry.
2. Cemeng plant ball mill .
3. Chemical industry ball mill .
