有色金属火法冶炼过程中,产出大量的炉渣,其中含有大量的余热。如何综合利用炉渣和回收其中所含的热能,是个极需研究的课题。这个课题在国外已进行了不少的工作,做过一些报导,而在国内却未引起人们足够的重视,也很少有人问津。一、炉渣余热的价值重有色金属火法冶炼所产的炉渣量及所含的热量示于下表1。从表1可以看出,每产出 Non-ferrous metal smelting process, the output of a large number of slag, which contains a lot of waste heat. How to comprehensively utilize the slag and recover the heat energy contained therein is a subject that needs to be studied very much. This topic has carried out a lot of work in foreign countries and made some reports. However, it has not given enough attention to people in China and few people have paid any attention to it. First, the value of slag heat Heavy non-ferrous metal smelting slag produced by the amount and the heat shown in Table 1 below. As can be seen from Table 1, each output
