高炉炉渣是炼铁过程中的主要副产品，其中含有大量的显热，而目前过渡水粒化工艺中显热没有得到回收，针对这一问题，实验室进行了大量的研究，大致可分为物理交换热法和化学回收热法。与物理法相比，化学热回收法具有较好的应用前景，本文评述了目前国内外高炉炉渣显热回收的化学方法，包括甲烷-水蒸气循环反应、甲烷重整、煤气化和生产高附加值产品，并对这些方法的优缺点进行了讨论，指出了化学法回收熔渣显热的关键问题和发展趋势。
Blast furnace slag is the main by-product in the ironmaking process,which contains large amounts of sensible heat.However,the sensible heat is not recovered in the transitional water granulation process at present.To solve this problem,many studies have been taken in the laboratory,which can be roughly classified into physical exchange heat method and the chemical recovery heat method.Compared with the physical method,the chemical heat recovery method has better prospects.This paper commented the chemical methods of sensible heat recovery of the blast furnace slag both inland and abroad at the present,which involved methane-steam circular reaction,methane reforming,coal gasification and production of high added value product.The disadvantages and advantages of these methods were discussed,and the key problems and the development trends of the chemical method of molten slag sensible heat recovery were also presented.
