Detail Company Introduction
Our hot rolling ball ground steel balls produced according to the standards of GB8649. yearly capacity is 72,000 tons of all sorts of ball ground steel balls of Φ20mm—Φ150mm. we independently researched and made fully new technique by ourselves to produce hot rolling ball ground steel balls and developed successfully. We created excellent production facility .The material used ball ground steel balls is special steel with excellent quality which have following technological characteristics:
(1) The special round steel we bought is from steel plant for corresponding steel balls.
(2) Round steel is heated to 800-900℃.
(3) Once ball formation by rolling machine of the production line.
(4) With advanced finishing technique: low abrasion rate, high hardness (Hardness for diameter more than 100mm of ground balls can be kept from surface to core). It has high tenacity, broken rate is rather low. More important, The life is double of casting balls. These products are widely used in mines, mineral media, all sorts of grinding machines in bad environment. These products can be used stability for a long time with excellent results.. Mineral engineers both domestic & overseas also have given their good comments for our products. They never see such good balls before which can greatly increase productivity and economic & social profits. Its properties are as follows:
1. High hardness, high abrasion-proof, high whole hardness: its surface hardness is HRC56-60. its central hardness is HRC54-59HRC. The hardness difference is less than 5HRC.
2. High tenacity: the impact tenacity is more than 17J/cm2.
3. Extremely low broken rate: the properties for peel resistant and broken resistant is more than 100 times those of other products. There are almost no breakages when ball impact times reach 100,000 to 200,000. Actual breakage rate is less than 0.01%.
