摘要
介绍了唐钢第二钢轧厂提高螺纹钢定尺率的生产实践。通过采取定重供坯、合理控制负差、提高轧机装配精度、控制切分轧制线差等一系列措施,使螺纹钢定尺率由99.08%提高到99.52%以上。
It is introduced the practice in No. 2 Steel Rolling Mill of Tang Steel to increase the rate of speci- fied lengths of reinforced bar. With a series of measures ： feeding fixed - weight billet, reasonably controlling negative tolerance, improving assembling precision of mill, controlling the error in splitting rolling, the rate is raised from 99.08% to 99.52%.
