Microwave Treatment of Slags: Case Studies of Cr-bearing Steel Making Slag and Ti-bearing Blast Furnace Slag

摘要

In this article, two examples of our attempt of microwave (MW) application to processing of slag are presented. First example is the Cr-bearing steel making slag. In stainless steel production, Cr containing slag is produced. In order to minimize the loss of Cr into the slag, it is attempted to reduce the Cr oxides with some elements such as ferro-silicon, because Cr is a valuable metal element and also it is needed to meet the requirements of the environmental regulations if they are to be land-filled.
