Method of keeping inductor spouts, downgates and outlet channels free of deposits in connection with a cast iron melt

摘要

A method of keeping inductor spouts, downgates and outlet casting channels and the like free of deposits during the production of a cast iron melt involves treatment with pure magnesium. Such deposits, which occur as reaction products and block the channels causing considerable maintenance expense, are prevented by the use of pure magnesium. The cast iron melt is flushed free of suspended highly basic reaction products, such as MgO, CaO, Al.sub.2 O.sub.3, FeO and MgS, in a predetermined magnesium treatment of the cast iron melt with pure magnesium by a simultaneous evaporation of magnesium not consumed in the magnesium treatment. By preventing the formation of deposits, the life of the vessel used is increased and maintenance costs are decreased.
