FIELD: metallurgy. ^ SUBSTANCE: cupola comprises well, beam that separates the well into the top melting chamber and bottom heating chamber, and bed. The beam is made of the cantilever beam mounted with a spaced relation with respect to the well side. The top side of the cantilever beam is inclined at an angle of 3-5 degrees toward the space, and the other burner is mounted in the melting chamber above the cantilever beam. The bed is made with a slope at an angle of 3-5 degrees toward the metal discharge. ^ EFFECT: enhanced efficiency. ^ 1 dwg
