Related parameters and quality control measures for forged steel grinding balls

- Apr 13, 2018 -

At present, the forged steel grinding balls in the market not only have different specifications, but also have excellent performance, which can meet the requirements of different users. Forged steel grinding balls range in diameter from 20mm to 200mm and high, medium and low chrome Ф12mm to Ф150mm.

 

From a whole point of view, the forged steel grinding ball is not only very accurate in size, but also round in shape, coupled with high hardness and good mechanical properties, as well as excellent qualities such as wear resistance, no deformation, no cracking, etc. The product has been favored by many users. Therefore, this product has long been widely used in large-scale mines, thermal power plants, cement plants and other industries, and has been well received by customers at home and abroad.

 

Forging steel grinding ball products related parameters:

Product hardness surface hardness, long service life;

High impact toughness, impact toughness greater than 12J/cm2, and the ball will not be deformed and out of round products from beginning to end;

Low crushing rate: The crush resistance is more than 10 times that of ordinary forging grinding balls, and the falling ball impact frequency is more than 20,000 times. The actual crushing rate is not higher than 1%.

 

Forged steel grinding ball product quality control measures:

1. Raw materials entering the factory for testing materials, qualified round steel storage;

2. hardness testing and impact testing;

3. metallographic examination and heart test to check the hardness of the heart.


In practical applications, if the operating conditions are relatively high, it is recommended to select forged steel grinding balls. It should be noted that the manufacturing process of forged steel ball products is also a key factor in determining its service life. Therefore, a reasonable forging process must be established during the production process.
