Steel ball
- Commodity name： Steel ball
- Product Description
-
Product Description:
In the operation of the ball mill, steel balls play a major role. The steel balls of the ball mill are the grinding material medium of the ball mill equipment. The grinding and peeling effect is generated by the collision and friction between the steel balls and the material between the steel balls of the ball mill. The steel balls are divided into cast balls and forged balls according to different manufacturing processes. The forged steel balls are forged by burning red steel, while the cast steel balls are formed by pouring molten steel into a ball mold.
Technical standards:
1. Whether the grinding steel ball is wear-resistant, the important data is hardness detection, which can be detected by Rockwell hardness tester. Practice shows that the service life of steel balls above HRC60 is higher than twice that of HRC40-50.
2. Low chromium steel balls refer to steel balls with chromium content ≤ 3.0 and carbon content between 1.80 and 3.30. The national standard requires that the hardness (HRC) of low chromium balls shall be ≥ 45 degrees or more. If the use quality of low chromium balls is guaranteed, heat treatment tempering or vibration aging treatment shall be adopted. Such as testing hardness
(HRC) below 40 degrees indicates that the hardness of low chromium balls is insufficient or over-burned.
Application areas:
Grinding steel balls are widely used in metallurgical mines, cement and building materials, thermal power generation, flue gas desulfurization, aerated concrete, magnetic materials, chemicals, coal water slurry, pellets, slag, ultrafine powder, fly ash, calcium carbonate, quartz sand and other industries.
