ABSTRACT:
An alloying addition agent for iron or steel baths comprising a mixture of a ferroalloy, an oxide of the desired alloying element and silicon carbide. The oxygen in the oxide enhances an exothermic reaction with silicon carbide to maintain the temperature of the bath. At the same time, the reaction produces very little smoke which normally results from prior art addition agents of this type, thereby reducing pollution of the surrounding atmosphere.
