摘　　要：介绍了攀钢金属制品有限公司棒材生产线提高定尺率的生产实践,通过控制加热炉氧化烧损、负偏差精度及切分规格线差控制、倍尺剪切精度提升、齐头辊道改进、各规格钢坯定长等措施,棒材定尺率由最初平均约96%~97%逐步提高到99.2%~99.3%。Introduced the practice to improving the rate of specified lengths,with controlling the oxidation burning loss of the heating furnace,the negative deviation accuracy and the cutting specification line difference control,the double ruler shear accuracy is improved,and the alignment table is improved.The fixing rate of bar is gradually increased from the initial average of 96%~97%to 99.2%~99.3%.
