前言硼铸铁是一种优良的减磨铸铁。几年前在缸套和活塞环行业已通过部级技术鉴定。与高磷铸铁相比,其耐磨性约提高50%。制造硼铸铁的主要方法是在电炉、冲天炉内或铁水包中添加含硼物质(称为加硼剂)。目前所状的加硼剂主要为硼铁合金,也可以用硼砂、硼酸。硼铁加硼剂具有比重大,吸收率高且稳定、加入工艺简单等优点;但其价格昂贵,使
Preface Boron cast iron is an excellent anti-wear cast iron. A few years ago in the cylinder liner and piston ring industry has passed ministerial technical appraisal. Compared with high-phosphorus cast iron, its wear resistance increased by about 50%. The main method of making boron cast iron is to add a boron-containing substance (called boronizing agent) in an electric furnace, a cupola or in a ladle. The current state of boron-added mainly boron-iron alloy, you can also use borax, boric acid. Boron iron boron additive with a large proportion, high absorption rate and stability, the addition of simple process, etc., but its expensive, so that
