Description:

?

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

at 8% ~ 15%, the carbon content at 2.4% ~ 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 ball mill liner has high strength, strong

toughness and good wear resistance performance, which represents the highest level of metal wear

resistant materials.

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,

4. lowering the breakage, and improving the performance.

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

? ? advanced spectrometer and durometer imported from Shimadzu.
