提高Φ14规格四切分轧制棒材定尺率实践

摘要

针对酒钢集团翼钢公司二轧线Φ14规格四切分棒材轧制时定尺率较低的问题，分析了影响棒材生产定尺率的因素，通过加强生产过程控制，采取精细化操作，减少轧制过程切头尾、减少纵肋差、减少四线差、控制负偏差、钢坯定重等措施后，定尺率指标得到了较大提高，生产成本得到有效降低。%Aiming at jisco group wing steel company two Gaxian Φ14 specifications when four segmentation bar rolling length rate is low , analyzes the factors that influence the rate of bar production scale through strengthening production process control , take the fine operation , reduce the process of rolling cut end , reduce difference of longitudinal rib , four line and negative deviation , billet weight control measures , such as to improve the scale rate larger , effectively reduce the production cost .
