<p>PURPOSE:To release hydrogen present in slag to gaseous phase by gas generated from a gas-generating agent added beforehand to solid slag in an electro-slag melting method using a cold start procedure with solid slag. CONSTITUTION:In an electro-slag melting method using a cold start procedure with solid slag, a gas-generating agent, e.g., preferably the carbonates of alkaline (earth) metals such as CaCO3, MgCO3, BaCO3, etc., is added to the solid slag in advance. Thus, the transfer of hydrogen present in solid slag into metal by releasing hydrogen in molten slag to the gaseous phase by means of bubbling caused by gas generated from the gas-generating agent added.</p> |
