<p>The invention relates to a steel melting plant having two stationary furnace vessels arranged on a furnace platform, especially for melting scrap, and having interchangeable vessel covers, one of which carries the heating device (electrodes), the melting process taking place alternately in the first or second vessel while the material to be melted is prepared in the other vessel. In order to design a steel melting plant of the type described at the beginning, in such a way that the duct for removal of the exhaust gases does not come into contact with the melt or melt splashes, and in addition opens into the respective other furnace vessel such that the heat of the exhaust gases can be optimally used, it is proposed that a suction bend which can be connected to a gas duct be arranged on each cover, that the gas duct opens in each case into the lower casing region of the other vessel, and a secondary duct leading to a dust removal device be branched from each gas duct, and that a gas shut-off valve be arranged in the gas duct, in the gas flow direction, behind the branch point of the secondary duct and, to prevent charged or molten material leaving the furnace, a closure device be arranged in the opening of the gas duct into the furnace. <IMAGE></p> |
