Description:

Middle Chromium alloyed casting iron in general refers to the alloy white iron with the chromium

content at 4% ~ 6%, the carbon content at 2.1% ~ 3.2%. Its distinctive features is that the M7C3

ype 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 middle chromium ball mill liner

has high strength, strong toughness and good wear resistance performance, which represents the

higher level of metal wear resistant materials.

Applications:

it is used in ball mill

Specifications:

Processing Technique

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

2. Constant temperature casting process ensuring the quality, no sonim, no pore etc.

3. Oil-immersed heat treatment and annealing process changing the internal organizational structure,

    lowering the breakage, and improving the performance.

4. Matter test, After the furnace test, semi-finished products and end products inspection was done by

    advanced spectrometer and durometer imported from Shimadzu.
