【摘要】 为提高优质圆钢表面质量,应用高压水除鳞技术,优化孔型设计并设定动态速降补偿,进口采用双排六轮导卫,控冷采用湍流管进行冷却等。采取一系列改进措施后,φ18～φ40mm规格圆钢不圆度平均由0.44mm降为0.25mm,粗糙度平均由4.96μm降为1.94μm,提升了产品档次的同时,也创造了良好的经济效益。更多还原

【Abstract】 In order to increase the surface quality of the high quality round steel,a series of improvement measures were taken. These measures include applying high-pressure water descaling technology,optimizing pass design,setting dynamic speed drop compensation,using import guide and guard with double tier and six wheels and adopting overfall pipe for control cooling and so on. After improvement,the ovalities of the round steel betweenφ18 mm andφ40 mm specifications reduced to 0.25 mm from 0.44 mm averagely;and the roughness reduced to 1.94 μm from 4.96 μm averagely;advancing product grates and creating good economicbenefits.更多还原
