摘　　要：将经CSP流程生产的、w(Si+Al)=1.0%为基的冷轧无取向电工钢,在MULTIPAS模拟器上进行连续退火工艺模拟实验。结果表明:该钢种的热轧板卷经过压下率约75%的冷轧,得到的冷轧,板完全再结晶温度为700℃,经820℃×60 s退火可获得磁性和力学性能较好的全工艺型产品,经720～780℃×60 s退火可获得力学性能和磁性较好的半工艺型产品。在MULTIPAS模拟器上进行冷轧无取向电工钢的连续退火模拟,采用合适的涂层保护可防止钢材表面氧化;选取合适的升温及降温速度,可使退火后的板形满足磁性测量的要求。在MULTIPAS模拟器上,进行不脱碳的冷轧无取向电工钢的连续退火模拟是可行的。The simulative experimentation on continuous annealing of the w（Si＋Al）=1.0% cold-rolled non-oriented electric steel is done in MULTIPAS simulator , which is produced by Masteel CSP production line. It is indicated that the entirely recrystallized temperature of the cold-rolled plate rolling about 75% reduction cold roiling is 700 ℃. The full-processed production which has the better magnetic capability and mechanical capability can be obtained by the annealing of cold-rolled sheet with 820 ℃×60 s. The semi-processed production which has the better magnetic capability and mechanical capability can be obtained by anneaUing of cold-rolled sheet with 720 -780 ℃×60 s. Appropriate coating can solve the oxidation of the steel plate surface experimentation. Selecting appropriate warming and cooling ratio can make the flatness after in the simulation annealing meet the requests of magnetism measurment. It＇s feasible that the continuous annealing of non-decarbonization cold-rolled non-oriented electric steel is simulated in MULTIPAS simulator.
