摘　　要： 采用控制轧制与控制冷却工艺,在适当调整钢坯化学成分的情况下,利用普碳钢轧制出了直径为6～10mm的400MPa细晶粒Ⅲ级钢筋.研究表明,通过复合强化,完全可以实现在不添加微合金元素的情况下,利用普碳钢轧制出满足GB1499-98的Ⅲ级钢筋.利用该工艺已在国内某厂成功轧制Ⅲ级钢筋3100余吨. 400 MPa hot-rolled ribbed bars in diameters from 6 to 10mm were produced with plain carbon steel through controlled rolling and controlled cooling adjusting the billets＇ chemical composition. The technological investigation showed that it is fully attainable to produce Grade Ⅲ bars meeting the National Standard GB1499-98 with plain carbon steel through comprehensive strengthening without adding any microalloy in the billets. The Grade Ⅲ ribbed bars have been successfully produced up to over 3100 ton in steelworks in China using technology proposed
