Abstract

PURPOSE: To impart strength at room and high temp. to briquette charcoal used as a reducing agent of a silicon ferro-alloy while suppresing increase in ash content, used by briquetting powdery charcoal by using powdery caking coal, starch or the like.
CONSTITUTION: As a briquette charcoal for reducing a silicon ferro-alloy, powdery caking coal is added to powdery charcoal and a size agent of a carbohydrate such as starch and/or molasses is further added thereto to briquette the same. By this method, strength at room and high temp. is imparted to the briquette charcoal while suppresing increase in ash content to the utmost and the obtained briquette charcoal can be used like lump charcoal as a reducing agent of silicon ferro-alloy.
