Under normal circumstances, in the manufacturing process of mining steel balls, air-cooled heat treatment process will be adopted, and a certain amount of various rare metal elements such as chromium, molybdenum, copper, boron, rare earth, anti-wear agent and the like will be added. The electric furnace is refined for a period of time. In general, mining steel ball products have extremely strong impact resistance and high wear resistance.
The main characteristics of this mining steel ball product are high overall hardness, strong impact toughness, low crushing rate, and less deformation. Usually its surface hardness can reach 55-65HRC, volume hardness reaches 50-63HRC, and the average hardness gradient distribution. Its resistance to crushing in large-scale mills is up to 5 times higher than that of ordinary grinding balls, and the number of falling ball impacts is more than 10,000 times. The actual crushing rate is not higher than 1%. During use, this steel ball will not be deformed or out of round from beginning to end.
The mining ball products include different specifications, among which can be divided into high, medium and low chromium, bainite, multi-alloy and other materials cast ball. The product is of good quality, high strength, durable, and not easily broken. It is an ideal wear-resistant material for mining and other industries.
In the mine field, people use mining steel balls to grind various kinds of ores, so the quality requirements for steel balls are very high. High-quality golf balls can not only improve work efficiency, but also reduce labor costs, material costs, etc., thereby effectively reducing mining costs.
Analyze from the application field, the mining steel ball is suitable for all kinds of metal mines, such as gold, copper, iron ore, silver ore, manganese ore. In the mine mining process, mining operations are the most human and material resources, and also the largest production costs to reduce mining costs. Therefore, the selection of suitable mining steel balls is one of the important ways to reduce the consumption of materials and increase productivity.
