<p>In brasquing the bottom and wall of alumina fusion electrolysis bath from the recovery of a used brasque by treatng refractory products containing carbon ground at the bottom and wall filtering insoluble components. The brasquing method is: the step to cover the bottom and wall of the bath with heat insulate bed composed of the mixture of C, NaF, CaF2, Al2O3, Na2SO4, and CaSO4, and the other step to supply the feeder equipment to negative electrode equipment settled on heat insulate bed composed of the mixture of C, NaF, CaF2, Al2O3 Na2O and bonding materials.</p> |
