Claims14
A frame for a sliding gate for an outlet of a metallurgical vessel comprising a refractory concrete member reinforced with at least one metal element having at least one lateral securing lug, said metal element being a metal frame embedded in the refractory concrete member, said concrete covering the inner, outer and under sides of the frame up to the lateral securing lug.
A frame for a sliding gate for an outlet of a metallurgical vessel comprising a refractory concrete member reinforced with at least one metal element having at least one lateral securing lug in which the underside of the concrete member has a lateral projection which is spaced apart from the lateral lug at a distance such as to facilitate assembly and protect the lug against heat radiation from under the outlet by a poured metal melt.
