- Abstract
The well-known technologies of remelting iron shavings lead to significant (30%) losses of metal. An electroslag smelting furnace with graphite electrodes is proposed for remelting iron shavings. The electroslag smelting technology is distinguished by the presence of a layer of highly superheated slag, which represents an independent metallurgical phase. A layer of highly superheated covering flux protects the melt from the atmosphere. For efficient remelting of iron shavings in an electroslag smelting furnace with graphite electrodes, use is made of the method of processing waste in smelting furnaces with liquid slag, the principle of operation of AC electric-arc furnace, and the design of DC electric-arc furnace. The combination of these properties of melting furnaces in an electroslag smelting furnace with graphite electrodes produces a synergetic effect of minimum (less than 2%) loss of metal. Combining the best properties of different furnaces creates a favorable condition for the manifestation of emergence. The new furnace is unique in melting iron shavings with minimum metal losses.
