抛丸清理滚筒的易损件有十几种,是铸造生产中清理铸件很恼火的事情。采用灰铸铁生产易损件,更换十分频繁,大大影响了生产效率。我校附属工厂为了保证铸件的及时清理,试制了一种白口耐磨铸铁,并取得良好效果。我们采用正交试验法,从九种方案中确定了最佳配方。现将化学成份、零件本体硬度和使用 Shot blasting cylinder wearing a dozen of wearing parts, casting production is very angry to clean up the casting thing. The use of gray cast iron production of wearing parts, replacement is very frequent, greatly affected the production efficiency. Our subsidiary factory in order to ensure the timely removal of castings, trial production of a white mouth wear-resistant cast iron, and achieved good results. We use the orthogonal test method, from the nine programs to determine the best formula. Now the chemical composition, parts body hardness and use
