摘要
CADI磨球是一种在采矿、建材等行业中广泛应用的研磨介质,目前行业内常使用油淬+空气中等温处理或盐浴等温处理的工艺调控组织、改善性能,但这些工艺存在环境污染、损害健康、安全隐患、能源浪费等问题。通过特定设备及工艺手段精准控制降温过程,采用水-空交替等温淬火的方法处理CADI磨球,能够达到与油淬/盐浴等温淬火相同的热处理效果。利用该工艺批量生产的CADI磨球具有良好的一致性,金相组织及力学性能指标符合标准要求,并在实际应用中取得了良好效果。
CADI grinding ball is a kind of grinding medium widely used in mining, building materials and other industries. In order to control its structure and improve its performance, the CADI ball is usually isothermal quenching treated by mineral oil or molten salt. However, the mineral oil or molten salt as cooling medium usually has a series of problems, such as environmental pollution, health hazards, safety risks, and energy waste. In this paper, the method of alternating isothermal quenching by water and air was adopted to treat the CADI ball, and the whole cooling process was precisely controlled by specific equipment and technological means. The results showed that the treated CADI balls had similar microstructure and wear resistance compared with those of the oil or salt bath isothermal quenching. The mass-produced CADI balls by this process had good consistency. Their metallographic structure and mechanical properties met the standard requirements, achieving a good effect in practical application.
