forged steel grinding ball

Forged steel balls have the characteristics of high volume hardness, compact structure, no loss of roundness, and no breakage. They are suitable for the grinding operations of semi-autogenous mills and ball mills in various metal mines, thermal power plants and other industries.

1. Product specifications: Φ20-150mm

2. Application fields:Various metal mines (gold mine, copper mine, iron mine, molybdenum mine, alumina mine), cement plant, power plant, steel slag plant, quartz sand plant, etc.

3. Product Introduction:The forged steel balls produced by the company are made of alloy steel from large steel mills and forged by the company's fully automated production equipment. They have precise dimensions, round geometric shapes, high hardness, good mechanical properties and wear resistance. , No deformation, no cracking characteristics.

4. Technological process:Raw material inspection - blanking - intermediate frequency furnace heating - forging into balls - quenching treatment - tempering treatment - testing - packaging

5. Product Features

       1. The breakage rate is less than 1%, and the breakage resistance is more than 2 times that of ordinary cast balls.

       2. High impact toughness: the impact toughness is greater than 12J/cm2.

       3. The overall hardness is high: the surface hardness is 58-65HRC, the volume hardness is 55-63HRC, and the hardness gradient is evenly distributed.

       4. No deformation: the steel ball will never deform or lose its round shape.

       5. The structure is dense, the cost performance is high, and the cost saving is obvious.

6. Quality inspection

       1. Hardness testing;

       2. Impact test;

       3. metallographic flaw detection;

       4. Pull the heart to test the hardness of the heart.
