STUDY ON FOAMING AGENT FOR MOLTEN LF SLAG

摘要: 讨论了白云石、石灰石、碳酸钡组成的碳酸盐发泡剂对LF熔渣发泡的影响。在实验室用两种溶渣进行了9种发泡剂试验。测定了熔渣的发泡时间和发泡高度,计算了熔渣的发泡指数。试验结果表明:因为碳酸盐的分解温度不同,单组分发泡剂的发泡特性也不同;在9种发泡剂中,白云石、石灰石、碳酸钡配比相等的3组分发泡剂的发泡指数最大。Abstract: In this paper the effect of the carbonate foaming agents which are composed of dolomite, limestone and barium carbonate on the foaming of molten LF slag is discussed. In the laboratory the nine kinds of foaming agent are tested in the two kinds of molten slag. The foaming time and the foaming height of the molten slag are measured. The foaming index of the molten slag is calculated. The results show that the foaming agents of the single component have different foaming behavior because the decomposition temperatures of carbonate are different. The foaming index of the foaming agent composed of the three components (dolomite,limestone and barium carbonate),the mixture ratio of which is equal,is the largest in the nine kinds of foaming agent.
