Study on Preparation of Obsidian Slag Cleanser for Molten Iron


Article Preview

The deslaging effects of Obsidian powder after heat treatment were researched, the results show that the water content in Obsidian can be adjusted by controlling heat treatment temperature and time, so that Slag cleanser coverage spreading speed and slag shell uniformity were improved, and the deslaging mechanism ware analyzed.
