THE INFLUENCE OF THE LINING’S MANUFACTURING TECHNOLOGY AND OF CAST IRON’S MELTING IN INDUCTION FURNACES ON THE SLAG FORMING

Abstract

The resulting investigation of reasons for scaffold creation and  crusible skulling in induction furnaces when  cast  iron melting is  presented in  the  article. It  is  established that scaffold creating and  slag  sticking both  take  place as  the refractory material interacts with  the  melting agents and both  depend mainly  on the  melting technique. The sudden drops of melting temperature, the motion of the melt at the expense of the  electromagnetic stirring, the  foreseen and unforeseen additions, harmful components which fall in the furnace with  the  furnace charge, interaction of the  melt, slag, atmosphere and crucible’s lining,  the furnace temperature, the area and speed of agent’s interreacting influence the  slag  creating process.
