我厂的连铸连轧机组中,熔铸部分用10吨燃煤式竖炉,熔体熔化后进入保温炉,再经三级流槽进入浇包,经人工控制浮阀以维持结晶轮中的液位,来实现连续铸锭,浇铸方式为水平12点,铸锭形状为梯形,截面积为1680毫米~2;连轧部分使用二辊悬臂式45°交错连轧机,经10道次轧制,截面减缩至78.5毫米~2的铝杆。我厂连铸连轧生产线投产后,在一段时间里,连铸铝线锭常产生断裂,经试验研究后,采取下列措施即可防止铝线锭断裂的问
I plant continuous casting and rolling mill, the casting part of the 10-ton coal-fired shaft furnace, the melt into the holding furnace after melting, and then into the ladle by three trough, the valve manually controlled to maintain crystallization of the wheel Level, to achieve continuous ingot casting method for the level of 12 o’clock, ingot trapezoidal shape, cross-sectional area of 1680 mm ~ 2; part of the continuous use of two-roll cantilever 45 ° staggered continuous rolling mill, after 10 rolling , Section reduced to 78.5 mm ~ 2 aluminum rod. After the continuous casting and rolling production line in our factory is put into production, for a period of time, the continuous casting aluminum ingot often produces the rupture. After the experimental research, the following measures can be taken to prevent the rupture of the aluminum ingot
