摘要/Abstract

摘要： 以模拟CSP工艺-真空感应炉熔炼含铜Hi-B钢(/%:0.06C,3.38Si,0.14Mn,0.013P,0.003S,0.019Als,0.37Cu,0.0015O,0.0087N)模铸成210mm×120mm×60mm板,Φ350mm二辊热轧机1065℃开轧经5道次从60mm轧成3.5mm板(终轧865℃)为试验基板,研究了轧后水冷和轧后水冷至580℃再空冷两种冷却工艺对实验钢组织和织构的影响。结果表明,热轧后水冷到580℃再空冷到室温的冷却方式有助于获得更高取向精准度的高斯织构、更低比例的黄铜织构以及其他合理的织构组成,较轧后水冷工艺更加适合实验钢。

Abstract: The simulated CSP process of tested plate of Hi-B steel bearing copper (/%: 0.06C, 3.38Si, 0.14Mn, 0.013P, 0.003S, 0.019Als, 0.37Cu, 0.0015O, 0.0087N) is melting by vacuum induction furnace and mold casting to 210mmx120mmx60mm plate, rolling at 1065℃ from 60mm to 3.5mm plate with finishing rolling at 865°C by Φ350mm two-high hot rolling mill and 5 passes. The effect of both processes-water cooling after rolling and water cooling to 580℃,air cooling after rolling on structure and texture of tested steel has been studied. Results show that the cooling process of water cooling to 580°C , air cooling to room temperature after hot-rolling is available to get Goss texture with higher orientation accuracy and lower content of Brass texture, and other reasonable texture component, as compared with water cooling process after rolling it is more suitable for tested steel.
