摘　　要：对比分析了在2种不同的精炼工艺（RH和LF）条件下，经CSP工艺生产的热轧和镀锌产品组织和性能的差异。研究表明：RH处理后，热轧卷晶粒尺寸增加，屈服强度下降20～30MPa左右；在采用相同的冷轧和热镀锌工艺条件下，RH处理对试验钢n值有所改善，但r值和杯突值EI值变化不大。The difference of structure and performance of hot-galvanized products from strips of CSP process were investigated for molten steel refined by RH and LF. For RH treated steel, the grain size of hot strip is increased from 15μm to 21μm, the yield stress decreased by 20～30 MPa at the same time, and n value of hot galvanized sheet is improved somewhat. The hot-galvanized sheet with better drawability can be produced by CSP line with RH treatment for molten steel.
