摘要
按照技术要求,结合生产现场实际情况,用150 mm×330 mm矩形坯轧制120 mm×245 mm规格电极扁钢,设计第1道次采用立轧孔,成品再前孔采用1.0 mm凹底的立轧孔,成品孔配以2 mm的下压力,侧壁斜度4.6%,解决了产品倒角、侧边垂直度以及扭曲、弯曲等问题,过钢量20 000 t,产品质量良好。
According to the technical requirements and the practical situation of production site, the rolling passes for producing 120 mm× 245 mm specification electrode flat steel by 150 mm × 330 mm rectangular bloom adopts vertical pass in the first pass, vertical pass of 1.0 mm concave base in the third from finish pass, down force of 2 mm in the finish pass and the slope of side wall 4.6%. It solved the problems of product chamfer, perpendicularity, twisting and bending ete and produced up to 20 000 t. The product quality is good.
