Abstract
Information on application of metallurgical, welding fluxes and slags and their classification by chemical composition is given. The importance of studying the regularities of gas interaction with molten fluxes and slags is shown. It is established that the problems of production and welding of metals with minimum (or controlled) content of gas impurities (oxygen, nitrogen, hydrogen) are the main ones at interaction of the three phases — gas-flux(slag)-metal. A review of literature on hydrogen, nitrogen and oxygen absorption by molten fluxes and slags and of the methods used to determine oxygen, nitrogen and hydrogen content in slags, fluxes, oxides, nitrides and aerosols is given. New procedures were developed for determination of oxygen, nitrogen and hydrogen content in slags and fluxes were developed, and currently available procedures were complemented. Ref. 30, Tabl. 5, Fig. 3.
