不同精炼模式对耐候钢Q355GNH质量的影响OA

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.
