【摘要】 研究了铜、锰复合代钼制造高铬铸铁抛丸机叶片,叶片工作面采用澈冷工艺。试验表明,叶片工作面晶粒细、硬度高、耐磨性好。使用寿命比低铬白口铸铁叶片高4—6倍。更多还原

【Abstract】 This paper deals with the shot-blasting blade of high chromium cast iron manufactured byadding copper and manganese to replace molybdenum.As to the work face of the blades chillingtests show that blades with high chromium cast iron giver fine grain,higher hardness and betterwear resistance.The service life of the blades is four to six times longer than that of the low ch-romium cast iron blades.更多还原
