Intorduction

Grinding steel balls‌ are a main tool for grinding materials, usually used in ball mills. Grinding steel balls produce abrasive effects through collision and friction with materials, thereby achieving the grinding effect of materials

Forged Ball Details:

1.Tthe broken rate of less than 0.5%, crush resistance is generally cast ball more than 10 times.
2.The impact toughness of high impact toughness than 18J/cm2: 8 meters, more than 20000 times of falling ball experiment.
3.The high hardness, the surface hardness of 55-68HRC, volume of hardness of 57-64HRC, and the average hardness gradient distribution.
4.No deformation, the ball is always not deformation, not out of roundness.
5.Compact structure, high performance-price ratio.

Test

The steel ball quality inspection process‌ mainly includes the following steps: ‌Appearance quality inspection‌: First, check the surface quality of the steel ball to observe whether there are obvious defects such as cracks, depressions, bubbles, etc. These defects will affect the performance and life of the steel ball.

Size and weight detection

Hardness test

Chemical composition analysis

Metallurgical structure analysis

Physical property test

Wear resistance test

Testing standards and items include hardness testing, appearance testing, wear resistance testing, tolerance testing, roundness testing, quality testing, composition testing, material testing, metal grade identification, chromium content testing, impact resistance testing, non-destructive testing, etc.
