不同精炼模式对耐候钢Q355GNH质量的影响

Effect of different refining modes on the quality of weathering steel Q355GNH

为了研究不同精炼模式对耐候钢Q355GNH质量的影响,对某钢厂耐候钢进行处理时,将R精炼炉改成L精炼炉,采用化学成分分析、力学性能测试、金相检验等方法对L精炼炉生产的耐候钢进行分析。结果表明:从R精炼炉转L精炼炉处理耐候钢的方法对耐候钢的性能没有影响,还能降低精炼成本且平衡物流。

In order to study the influence of different refining modes on the quality of weathering steel Q355GNH,the R refining furnace was changed into L refining furnace when the weathering steel in a steel plant was treated.The weathering steel produced by L refining furnace was analyzed by means of chemical composition analysis,mechanical property test and metallographic examination.The results show that the method of treating weathering steel from R refining furnace to L refining furnace had no effect on the performance of weathering steel,but also reduced the refining cost and balanced the logistics.
