在实验室条件下模拟薄板坯连铸连轧流程试制了取向电工钢。结果表明,实验室条件下模拟薄板坯连铸连轧流程生产取向电工钢是可行的。试制的电工钢成品磁感较好,铁损偏高。实验中,铸坯中柱状晶发达,有穿晶出现,铸坯心部有少量等轴晶。热轧板和常化板晶粒尺寸沿板厚方向有明显变化,组织沿板厚方向可分为表面脱碳层、过渡层、中心层。中间退火后晶粒细小,脱碳退火后晶粒细小均匀。试验中,常化和产品厚度对产品磁性能的影响不明显。
In the laboratory conditions simulated thin slab continuous casting and rolling process trial oriented electrical steel. The results show that it is feasible to simulate thin slab continuous casting and rolling process under laboratory conditions to produce oriented electrical steel. Trial electrical steel products better magnetic induction, high iron loss. In the experiment, the columnar crystal developed in the slab, with transcrystallization appears, there is a small amount of equiaxed crystal in the heart of the slab. Hot-rolled plate and the normalized plate along the thickness direction of the grain size has obvious changes in the thickness direction of the tissue can be divided into surface decarburization layer, transition layer, the center layer. After the middle of small grain annealing, decarburization annealing fine grain uniform. Test, the normalization and thickness of the product magnetic properties of the product is not obvious.
