FIELD: metallurgy.
SUBSTANCE: cooling panels are fixed in the metallurgical tank in order to make internal refractory of the shell. Each panel has a pipe curved such as to make an internal and external section of the panel and with a zig-zag shape with the cooler flowing through the pipe. The panels are equipped with rods projecting out of the shell through the holes in the shell as well as through the tubular projections of the shell surrounding the holes. The rods are connected with the external sides of the projections by means of metal discs ensuring sealing of the above holes. The connectors used for supplying and withdrawal of the cooler in the panel project out through the holes in the shell, surrounded by the tubular projections and welded to the projections by means of the discs in the manner similar to the above-mentioned rods.
EFFECT: faster and simpler change of the cooling panels.
