Abstract: The influence of heating temperature(1200 ℃,1180℃)of 180 mm cast slab,rolling passes for 2.3 mm hot coil(7 pass and 5 pass),finishing rolling temperature(780~860℃)and coil temperature(≤710℃)on iron  loss and magnetic intensity of 0.5 mm cold rolled non-oriented silicon steel 50W600 has been tested. The results showed  that decreasing heat temperature of cast slab, increasing finishing rolling temperature and coiling temperature were available to improve magnetic properties of the cold rolled non-oriented silicon steel; while the rolling passes had no significant influence on magnetic properties of steel products.

摘要： 试验了180mm铸坯加热温度(1200℃、1180℃)、2.3mm热轧卷轧制道次(7道次、5道次)、精轧终轧温度(780～860℃)和卷取温度(≤710℃)对0.5mm冷轧无取向硅钢50W600的铁损和磁感应强度的影响。结果表明,降低铸坯加热温度,提高终轧温度和卷取温度,有利于改善该冷轧无取向硅钢成品的磁性能;而粗轧道次对成品磁性能无明显影响。
