Forged balls for gold ore mine mineral processing and the characteristics of use

- May 02, 2019-

Forged balls for gold ore mine mineral processing with good surface quality, good impact resistance, strong toughness, good wear resistance, and are not easily broken and round. We use forging and stamping methods to heat the metal until the temperature reaches 1050 ° C (± 50 ° C), using a forging machine to apply pressure to the metal blank to plastically deform it to obtain a certain mechanical properties, shape and size. The processing method of forgings.

 

Forged balls are used for gold mineral processing. Forging can eliminate defects such as as-cast looseness caused by metal in the smelting process, optimize the microstructure, and at the same time, the mechanical properties of the forgings are generally better than the same materials due to the preservation of the complete metal flow lines. casting. Forging steel balls must wear the most wear-resistant materials. We use steel produced by the national extra-large steel mills. It is also a kind of material. The quality produced in different steel mills is also different, and the quality of forgings is good or bad. 80% depends on the quality of the material, such as the use of high manganese steel, good impact resistance, strong toughness, good wear resistance, not easy to break. Forged steel balls are favored by users because of their low price, economy and durability.

 

Characteristics of forged balls used in gold mineral processing

 

1. The breaking rate is less than 0.5%.

 

2. High impact toughness: impact toughness is greater than 18J/cm2, and 8m ball drop test is more than 20,000 times.

 

3, the overall hardness is high: surface hardness of 58-65HRC, volume hardness of 56-63HRC, and hardness gradient distribution average.

 

4, no deformation: the steel ball is always not deformed, not lost.

 

5, the organization is compact, cost-effective, and significant cost savings.
