Low Chrome Electro Galvanized Steel With Metal Wear Resistant
Quick Detail:
Low Chrome Alloyed Ball Mill Liner
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, martensite(the 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.
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.
