Castings And Forgings Steel Ball With HRC58-66 For Mining Machine

1. Preparation method of grinding steel ball:
Low chromium steel ball is the most important grinding body in ball mill, which is called grinding steel ball abroad. Low chromium steel balls are produced by medium frequency electric furnace melting, metal mold or sand casting, so domestic wear-resistant material manufacturers often called low chromium alloy casting balls.

2. Technical standard of grinding steel ball:
(1) Hardness test is the most important data for whether the grinding steel ball is wear-resistant, which can be tested by Rockwell hardness tester. Practice shows that the service life of steel balls with HRC60 and above is more than twice of HRC40-50.
(2) Low chromium steel ball refers to chromium content ≤3.0%, carbon content between 1.80%-3.30% of the steel ball is low chromium ball, the national standard requirements of low chromium ball hardness (HRC) must be ≥45 degrees above, if the use of low chromium ball quality recommendations must use heat treatment tempering or vibration aging treatment. If the test hardness (HRC) is below 40 degrees, the low chromium ball hardness is insufficient or overburning.
(3) Application field:
Grinding steel balls are widely used in metallurgical mines, cement building materials, thermal power generation, flue gas desulfurization, aerated concrete, magnetic materials, chemical industry, coal water slurry, pellets, slag, ultrafine powder, fly ash, calcium carbonate, quartz sand and other industries.
