摘要
通过固溶度积公式计算及热模拟实验,对不同热装和加热温度条件下的无取向硅钢铸坯中析出相进行了研究.在低于950℃热装时,铸坯中AlN的析出量和尺寸不再变化,但MnS和AlN-MnS的数量及平均尺寸随着热装温度降低而进一步增加,并在温度低于600℃时达到最大值后保持不变.与1200℃相比,1100℃加热的铸坯中AlN、MnS的总固溶量相对更少.相比850℃热装,600℃热装再加热到1100℃的铸坯中AlN和MnS的总固溶量更少,且AlN和MnS尺寸更大.合适的热装温度和加热温度分别为600℃和1100℃.
Based on solubility product calculation and thermal simulation experiments, precipitated phases in continuous casting slabs of non-oriented silicon steel were systematically studied at different hot charging and heating temperatures. When the hot charging temperature is below 950℃, the content and size of A1N remain unchanged, but the quantity and size of MnS and A1N-MnS increase when the hot charging temperature decreases, reach maximum and remain unchanged when the hot charging temperature is below 600 ℃. The total content of A1N and MnS solid solution in the slab heated at 1100 ℃ is less than that heated at 1200 ℃. Compared with the slab hot-charged at 850 ℃ and heated at 1100 ℃, the total content of A1N and MnS solid solution is less and the size of A1N and MnS is larger in the slab hot-charged at 600 ℃ and heated at 1100℃. The appropriate hot charging temperature and heating temperature are 600 ℃ and 1100 ℃, respectively.
