Produção de aço ligado ao manganês em forno de indução utilizando cadinho de alumina a partir de borra de alumínio e melaço de cana.

Abstract

In the production of aluminum a waste called aluminum dross is generated, which presents great potential as raw material for the manufacture of refractories. This work seeks to produce refractory crucibles, from the aluminum dross and sugar cane molasses, for the production of manganese steel in induction furnace. The crucibles, for use in the induction furnace, must exhibit high resistance to thermal shock, good mechanical resistance and good resistance to wear under the conditions imposed for furnace. Crucibles were obtained from a mixture of aluminum dross, mullite and molasse. The crucibles produced were tested by melting steel balls and adding pure carbon and pure manganese. It was concluded that the crucibles produced have suitable properties for use in the induction furnace, because it was possible to melt and maintain the steel in a liquid state long enough for addition of alloying elements.
