感应加热具有加热速度快的特性,故生产率高,氧化少;炉子本身无升温时间,易于启动,电率高,便于实现生产自动化等一系列优点。在我国工业生产上得到越来越广泛的应用,由于这一新的炉种在生产使用中尚存有一定的缺点,其中钢锭加热炉炉衬的寿命低,尤为当前突出矛盾之一,如某厂钢锭加热炉已试过的炉衬其材质为重质的只能用几炉,轻质的最多只用二十炉左右,其它厂感应炉虽已正常运行,但仍把炉衬作为关键技术问题之一提
Induction heating has the characteristics of fast heating, so the high productivity, less oxidation; furnace itself does not heat up time, easy to start, high rate, easy to achieve production automation and a series of advantages. In our country, industrial production has been more and more widely used. As the new furnace has some shortcomings in production and use, the life of furnace lining of ingot furnace is low, especially one of the prominent contradictions, such as a factory Steel ingot furnace has tried the lining of its heavy material can only use a few furnaces, light up to only about 20 furnaces, although the other factory induction furnace has been normal operation, but still the lining as one of the key technical issues mention
