Order On-line Tracking
(1).Raw material: Round steel ,the raw material of forged balls ,are totally ordered from our national large -scale steel mills. We can also provide special processing as per special requirements of different grinding balls
(2).Scientific Proportioning :Rational chemical composition is gradually optimized and formed by our technical staff after continuous tests. It is unique .The best configuration of various alloying elements can combine the ball′s hardness and toughness’ at their best.
(3).Electric furnace smelting: All cast steel balls are produced by intermediate frequency electric furnace .The purity and stability of materials are effectively ensured after uniform temperatures conditioning and twice hot metal purificati0n.
(4).Assay before furnace :Temperature control is an important and complex process during cast steel ball production. Different tapping temperature and heat temperature are sensitively reflected in the quality of the products. It is requested to master the proper pouring temperature ,mold temperature ,so that can make sure the products achieve a good state of body tissue during the transition from Liquid to solid states.
(5).Mould forming: Pouring when the molten iron temperature difference between molten iron and the molds. In this way ,the ball can achieve internal organization of grain refinement and be more dense .Meanwhile ,the carbide is radically arranged ,and such Carbide is embedded in the matrix again during grinidng process, forming harde layer continuously .So that the hardness and thoughness is maintained to a reasonable.
(6).Heat treatment: We have two sets of heat treatment production line .One is oil quenching, the other is air quenching ,so that the grinding balls can be burring through quenching. And the grinding media has the characters of high hardness ,good thoughness,low wear rate ,low break rate, wear -resistant etc. through tempering .
