Abstract

PURPOSE: To prepare a high-temperature reactive substance capable of forming a large amount of combustible gas by stable operation, by recovering a gas evolved in a closed type electric furnace using coal having a specific composition as a reducing agent when the high-temperature reactive substance is prepared by the closed type electric furnace.
CONSTITUTION: In preparing a high-temperature reacrive substance, e.g., calcium carbide, etc. using a reducing agent consisting of a carbon material by a closed type electric furnace, highly volatile coal with volatile content≥15wt% alone or it and other carbon material as a reducing agent and other blending raw material are fed to the electric furnace in such a way that the ash content in the total carbon material is ≤15wt%. For example, when calcium carbide is prepared, the reducing agent is blended with quick lime, and when ferrosilicon is prepared, the agent is blended with mill scale of silicic anhydride, etc., and the blend is fed to the closed type electric furnace. When about 5W10wt% sawdust, wood pieces, etc. is used in the preparation, the face of the furnace becomes much better.
