摘要
介绍了奥氏体基高铬铸铁磨球的生产工艺和要点。由于其具有铸态奥氏体组织 ,从而具有较高的冲击韧性。另外 ,在冲击磨擦状态下这种组织会向马氏体相转变 ,发生加工硬化现象 ,从而使这种材料在具有高韧性的同时还具有高的抗冲击磨损能力。生产应用表明 。
The paper mainly introduces production and applction of the austenitic high chromium cast iron grinding ball. For obtaining austenite in casting state, the balles have stronger impact toughness. In addition,martensite transformation happens under impact wear conditions, mean while work hardening will also happens ,thus the material has higher toughness and still improves its impact resistance of composite. In the industrial application it can give play to its fine wearing capacity and economy.
