余热处理复合铸钢磨球的研制

Developing Composite Steel Casting Grinding Balls Treated by After-heat

利用铸造余热、采用中断正火的工艺,直接对铸造的复合组织耐磨铸钢磨球进行热处理,从而可以得到既有良好的强韧性及耐磨性,且价格低廉、工艺简单的耐磨磨球。

When wear-resisting steel casting grinding balls with compound structure were treated directly by interrupted normalizing process using after-heat of casting, the obtained grinding balls have the advantages of ideal strength and toughness, good wear-resistance and low cost of simple process.
