ABSTRACT:
The operation of mineral wool cupolas is improved in several respects and a waste material is efficiently disposed of by using spent pot lining from electrolytic aluminum reduction vessels in the mineral wool cupolas as a partial or complete replacement for coke. The spent pot lining is impregnated with a cryolytic type slag material which aids in both reducing the reactivity of an already unreactive graphitic material such that it burns low in the cupola with desirable thermal results and also prevents the formation of siliceous build-up in the cupola hearth areas. Several variations of cryolytic impregnated carbonaceous materials having the desirable effect of the invention are possible and described.
