采用盛钢桶整体内衬成型设备能够在很大程度上使内衬操作机械化,并可减少维护盛钢桶的劳动量,同时,可以少用稀块的耐火材枓,把更便宜的耐火材料利用起来。但是整体内衬的强度低于砖衬。因此,使用这种盛钢桶出钢,引起了一系列突出的困难,这联系到组织无压力出钢以避免钢水冲坏内衬的受冲部位。这对于溶池深的双床平炉以及配备单流出钢槽的平炉特别重要,因为这种人们熟悉的,被广泛采用的出钢槽(图1—a)的结构不能减慢钢水流入盛钢桶的速度,它的底部是平炉出钢口底部的延长,都倾斜5—8°,钢流获得加速
The use of a steel ladle lined with integral lining equipment to a large extent the mechanization of the lining operation and reduce the maintenance of ladle labor, at the same time, you can use fewer pieces of refractory 枓, the cheaper refractories Use it. However, the strength of the overall lining lower than brick lining. Therefore, the tapping of steel with this ladle poses a series of outstanding difficulties, which are linked to the impacted part of the tissue which is tapped without pressure to prevent the molten steel from sabotaging the lining. This is of particular importance for deep deep pool double hearth furnaces and open hearth furnaces with single outlet troughs, as the familiar configuration of the widely used tapping trough (Figure 1-a) does not slow down the flow of molten steel into the ladle Of the speed, it is the bottom of the flat furnace tapping the bottom of the extension, are inclined 5-8 °, the steel flow is accelerated
