摘要
SCHLICK抛丸机是从西德进口的钢结构预处理设备 ,为取代进口易损配件叶片 ,采用多元高铬合金抗磨铸铁试制 ,该材料经热处理后 ,显微组织为马氏体 +条块状一次碳化物及在回火马氏体基体上析出的颗粒状二次碳化物 ,硬度HRC6 4～ 6 7,ak为 3J·cm-2 ～ 5J·cm-2 ,经现场生产考核 ,使用寿命与原进口叶片相当。
SCHLICK shot blasting was imported from West Germany. In order to replace imported blade, high chromium cast iron was investigated. Heat-treated high chromium cast iron microstructure consists of martensite, primary carbides with ribbon-like morphology and secondary carbides with grain-like morphology. Its hardness and a k are HRC 64～67 and 3J·cm -2 ～5J·㎝ -2 . Respectively, the test results showed that the Cast -iron -high-Chromium blade and imported blade were of the same useful life.
