摘　　要：介绍了马钢第三钢轧总厂为降低低合金钢Q345B合金消耗所采取的增C降Mn冶炼工艺。结果表明:在确保钢材力学性能的前提下,采取增C降Mn冶炼工艺,降低低合金钢Q345B合金消耗的方法是可行的,w(C)每提高0.01%,w(Mn)可降低0.06%。In order to reduce the alloy consumption of low-alloy steel Q345 B,the process of increasing C content and reducing Mn content was implemented by No.3Steelmaking Rolling Works of MaSteel.The results showed that this process was feasible and ensured the mechanical properties of steel,and the mass fraction of Mn could reduce0.06 % when C increased 0.01 %.

关 键 词：低合金钢 力学性能 铁合金消耗
