Abstract:

On the basis of brief description of the present situation of carbon content and reactivity indexes in our country,it is put forward that there are three existing forms of carbon in the lime,i.e.impurity carbon,primary carbon and regeneration carbon.The formed cause and distribution features of various forms of carbon are analyzed.The morphology and regeneration carbon distribution of the lime produced from two kinds of lime kilns are determined by SEM and EPMA and the multiple kinds of technical measures for reducing different forms of carbon in metallurgical lime are put forward.
