Analysis of steel slag treatment technology and waste heat recovery technology

The steel slag treatment and waste heat recovery technology and device in China and abroad were listed, compared and analyzed through a large number of examples. Through analysis and comparison, it shows that the heat in molten slag could be recycled and re-used through different steel slag processing combined with scientific, economic, reasonable waste heat recovery technology, and could get remarkable achievements. At the same time, it was pointed out that due to the inherent characteristics and physicochemical conditions of steel slag, many waste heat recovery problems need researcher’s continuing research to solve. Finally, the prospect of steel slag waste heat recovery were discussed and suggested that the government and related fields should give enough attention and support for field of steel slag waste recovery.
