Φ 10 mm热轧带筋钢筋四线切分轧制技术的开发

DEVELOPMENT OF FOUR-STRANDS SPLITTING ROLLING TECHNOLOGY FOR Φ 10 mm HOT ROLLING RIBBED BAR

为满足国内、外市场对Φ 10 mm热轧带筋钢筋的巨大需求,唐钢公司第二钢轧厂通过孔型设计、导卫选型等完成了Φ 10 mm热轧带筋钢筋四线切分轧制技术的开发。在实际生产中,通过改进轧辊材质、控制轧辊轴向窜动及弹跳、提高轧辊的加工精度等技术措施,解决了轧件出成品架次顶出口、切分架次出口堆钢、轧辊磨损严重等问题,实现了Φ 10 mm热轧带筋钢筋的稳产、高产。

In order to meet the great demand ofΦ10 mm hot rolled ribbed bar at home and abroad,Tangsteel No.2 rolling plant completed the development of four-strands splitting rolling technology forΦ10 mm hot rolling ribbed bar.In actual production,the problems such as the bent of the finished product,the exit steel-heaping of slitting and the heavy abrasion of the roller are sloved through the technical measures such as improving the material of roller,controlling the shifting and bouncing of rollers,improving the machining accuracy of roller.Finally,the stable yield and high yield ofΦ10 mm hot rolled ribbed steel bar are realized.
