本文阐述了提高磨球与衬板的抗磨性与降低其消耗的重要经济价值.并指出,当前存在的主要问题是工件的选材不当.应推广使用白口铁磨球与衬板.对工件所受冲击动能进行计算及分析表明,白口铸铁件只要有一定最低的冲击韧性,就可以满意地达到使用要求.白口铁与其它钢铁材料比较,无论在实验室测试,还是制成磨球及衬板在观场使用,其耐磨性均最高,单位成本的抗磨性也最高.最后,根据磨球与衬板的磨损失效原因与机制,讨论了进一步提高这类白口铁工件抗磨性的冶金因素.
This article elaborates the important economic value of improving wear resistance and reducing wear of ball and liner, and points out that the main problem currently exists is the improper material selection of the workpieces, The impact kinetic energy of the calculation and analysis shows that white cast iron as long as there is a certain minimum impact toughness, you can satisfactorily meet the requirements. White iron and other steel materials, whether in laboratory tests, or made of ball And liner in the view of the use of the field, the highest wear resistance, the highest unit cost of wear resistance.Finally, according to wear ball and liner wear failure causes and mechanisms discussed to further improve such white iron workpiece anti-wear Abrasive metallurgical factors.
