转炉热模型一般是一座吹氧的中(高)频感应炉,由于感应圈需要水冷以及炉衬薄等原因,存在“炉衬冷”及上部炉衬粘钢、粘渣等缺陷。为此,对转炉热模型做了改进。所用热模型是由451型150kg可控硅中频无芯感应熔炼炉改装而成。为克服“炉衬冷”等缺陷,扩大了感应圈,加进了绝热性能良好的耐火纤维绝热层,加厚了炉衬,并对炉衬工作层采取了外感应补偿加热的方式,即在工作层与绝层之间加进了
The converter thermal model is generally an oxygen blowing medium (high) frequency induction furnace. Because the induction coil needs water cooling and the lining is thin and so on, there are defects such as “lining cold” and sticking slag and slag on the upper lining. To this end, the converter thermal model has been improved. The thermal model used by the 451 150kg SCR intermediate frequency induction furnace refitted. To overcome the “cold lining” and other defects, expand the induction ring, adding a good insulating properties of refractory fiber insulation, thickening of the lining, and the lining of the working layer to take the external induction heating method of compensation, that is, in the working layer and Added between the layers
