摘要
为了满足建筑业对高强度、高塑性钢筋的要求 ,选用Nb进行微合金化 ,采用转炉冶炼和钢包底吹氩搅拌 ,以 1 1 0mm× 1 1 0mm连铸方坯为原料 ,用高速线材轧机生产出Φ6～Φ1 2mm小规格热轧带肋钢筋 ,其产品质量完全符合GB1 499-1 998标准要求。
The ribbed bar must have the properties of high strength and plasticity to meet the need of construction industry Therefore,the small specification of Φ6～Φ12mm hot rolled ribbed bar were developed by Qingdao Iron and Steel (Group) Co., which appied some advanced technologies,such as Nb micro alloying,converting,ladle bottom blown argon stirring,continuous casting to 110mm×110mm billet and rolling by high speed wire rod mill The products accord totally with the standard of GB1499-1998
