Abstract
In the theoretical chemistry for steel melting, only the equilibrium-constants for the chemical reactions has been hitherts dealt with. The author considers, however, that this problem is not so simple, whilst no body ever attained to its practical solut on.
The problem for steel melting must be a problem to find the condition of equilibrium for the whole system of slag and metal at their practical temperatures. Varous chemical elements and chemical compounds exist both in the steel and the slag. At the surface between them various physical phenomena and chemical reactions take place and all these phenomena should mut ally be in an equilibrium.
In this paper, are described the theory of such chemical equilibrium and its practical applications for the theoretical analys's of the actual steel-melting.
