摘要
2.9 mm热轧3%Si高牌号无取向硅钢板(/%:0.004 6C、3.04Si、0.32Mn、0.49Als、0.004S、0.013P、0.0042N)由CSP(Compact Strip Production紧凑式带材生产线)流程:120 t BOF-70 mm CC-热轧工艺生产。热轧终轧温度872℃,卷取温度683℃。铸坯及热轧板的组织和夹杂物的分析结果表明,铸坯组织为典型的贯穿柱状晶组织;热轧板边部为再结晶组织,中部为纤维组织带有少量再结晶晶粒;高牌号无取向硅钢的主要夹杂物为铸坯-Al_2O_3,AlN和Cu_2S+MnS;热轧板-Al_2O_3,AlN,AIN+MnS和Cu_2S+MnS。
The 2.9 mm hot rolled 3% Si high grade non-oriented silicon steel plate （/%： 0.004 6C, 3.04Si, 0. 32Mn, 0. 49Als, 0. 004S, 0. 013P, 0. 004 2N） is produced by CSP （ Compact Strip Production） flow sheet i. e. 120 t BOF-70 mm CC-hot rolling process with end rolling at 872 ℃ and coiling at 683℃. The analysis results on structure and inclusions in casting slab and hot rolled plate show that the structure of slab is typical trans-columnar crystal, the structure of hot rolled plate at edge is recrystallized grain and in center of plate is fibrous structure with minor reerystallized grains; and the main inclusions in high grade non-oriented silicon steel are A1203 , A1N and Cu2S ＋ MnS in costing slab and A1203 ： A1N. A1N ＋ MnS and Cu.S ＋ MnS in hot rolled plate.
