一些外国公司提出了把反射炉改造成高效率、高生产能力冶炼设备的几个可能方案,其主要特征是广泛使用氧气。芬兰奥托昆普公司和美国德雷沃公司提出的方案是把反射炉改造成氧气闪速熔炼炉。一台这样的炉子可以代替2～3台反射炉。为此,要按奥托昆普法在反射炉顶上加设 Several foreign companies have proposed several possible solutions for retrofitting furnaces into high-efficiency, high-capacity smelting equipment, the main feature of which is the widespread use of oxygen. The solution proposed by Outokumpu, Finland and Drewworth, USA, is to retrofit the reflector furnace to an oxygen flash smelting furnace. One such stove can replace 2 ~ 3 reflector furnaces. To this end, according to the Outokumpu law in the reflective roof plus
