球墨铸铁磨球以其硬度高、韧性好、综合机械性能良好,其磨矿单耗0.69kg以下,近年来,在湿磨磨机中得到了广泛应用。在实际生产中,球墨铸铁磨球除了在前期控制好球化率及化学成份,还要控制好热处理的淬火过程。1磨球淬火过程控制一般主要用框架式淬火器具,多采用上口入,四周及底 Nodular cast iron ball with its high hardness, good toughness, good overall mechanical properties, the grinding unit consumption of 0.69kg or less, in recent years, wet grinding mill has been widely used. In actual production, ductile iron ball in addition to early control of the ball rate and chemical composition, but also control the quenching process heat treatment. 1 grinding ball quenching process control is generally mainly used frame quenching apparatus, and more with the mouth into the circumference and the end
