Abstract

一种主要用于石材加工及其它研磨行业的高硬度合金白口铸铁磨料。它的实现是在不同类型的熔炉中熔炼具有：C含量为3-4％；Si：0.4-1％；Mn：0.5-2％；S：0.1-0.2％；P：0.1-0.15％；Cr：0.3-1％；B：0.05-0.2％；Re：0.04-0.06％；Fe：92.29-95.5％(重量比)成份的铁水，经粒化处理后，铸铁磨料基体中含有60％以上的硬相组织，显示微硬度Hv＞900，宏观硬度(HRC)为55-68，磨料回用率为70％。

Description

本发明属于合金铸铁磨料的新材料，主要用于石材加工及其它用于研磨的行业。
目前我国用于研磨行业的磨料，是把白口铸铁铁水经水喷、气喷、溅轮，离心等方法粒化处理成铸丸或将其破碎成沙砾。这种磨料基体中有30～50%的较软（HV＜800）的组织，因此，宏观硬度低、耐磨性差，磨料损耗指标高。
本发明的目的在于建立一个新的磨料基体，以大幅度的提高磨料的硬度，降低磨料损耗，提高石材加工效率，降低成本增加效益。
本发明的实现是：在不同类型的熔炉中熔炼具有C含量为3～4%;Si含量为0.4～1%;Mn：0.5～2%;S：0.1～0.2%;P：0.1～0.15%;Cr：0.3～1%;B：0.05～0.2%;Re：0.04～0.06%;Fe：92.29～95.5%（重量比）成份的铁水。经粒化处理后，其铸铁磨料基体中有60%以上的硬相组织，显微硬度HV＞900，铸铁磨料宏观硬度（HRC）为55-68。铸铁磨料性能不受粒化处理方法的影响。
按上述成份熔炼而成的铸铁磨料，与常规磨料相比，其生产效率提高37%;锯条磨损降低30%;磨料回用率达70%。
