【摘要】：为减少连铸与热轧工序之间坯料再加热的能源消耗,连铸直轧技术蓬勃发展,其关键技术之一在于连铸与轧制工序之间的补热工艺。针对板坯连铸直轧实际生产中对补热工艺的要求,建立了纵向磁通和横向磁通感应补热有限元模型,分析了板坯的补热过程。结果表明,纵向磁通对板坯表面整体补热效果好,但无法解决板坯边角温度偏低的问题;横向磁通可有效地对板坯边角进行局部补热;选择合适的电流大小和板坯移动速度,可使板坯温度分布更均匀。同时,使用自制的感应补热样机做补热试验,对补热效果进行检验,所得的试验结果与模拟结果一致。分析结果对板坯连铸直轧在实际生产中的感应补热工艺具有指导意义。
[Abstract]:In order to reduce the energy consumption of reheating of billet between continuous casting and hot rolling process, continuous casting and direct rolling technology has been developed vigorously. One of the key technologies is the reheating process between continuous casting and rolling process. The finite element models of longitudinal flux and transverse flux induction heat compensation are established to meet the requirements of heating supplement process in slab continuous casting and direct rolling production, and the process of slab heating compensation is analyzed. The results show that the longitudinal flux has a good effect on the whole surface of the slab, but it can not solve the problem of low temperature of the edge angle of the slab, the transverse flux can effectively heat the edge angle of the slab, select the appropriate current size and the moving speed of the slab. The slab temperature distribution is more uniform. At the same time, the self-made induction heating prototype is used to test the effect of heating compensation, and the experimental results are in agreement with the simulation results. The analysis results are of guiding significance to the induction heating process of slab continuous casting and direct rolling in actual production.
