摘要
介绍了日照钢铁控股集团有限公司第二棒材生产线采用三线切分工艺生产?18 mm热轧带肋钢筋的实践,其利用?16 mm钢筋的孔型系统,结合现有工艺设备,兼顾工艺共用性,开发了新的孔型系统和导卫装置,成功实现了?18 mm带肋钢筋的三线切分轧制,使其产量提高了41%,产品合格率达99.9%,作业率达89%以上。
The three-strand splitting rolling practice forΦ18 mm ribbed bar in No.2 bar line of Rizhao Iron&Steel Co.,Ltd.,was introduced.Using the original pass system ofΦ16 mm ribbed bar,and combining the existing processing equipment,the new pass system and guide and guard forΦ18 mm ribbed bar were developed.The three-strand splitting rolling forΦ18 mm ribbed bar was realized with increased output of 41%,product pass rate of 99.9%,and operating rate of above 89%.
