摘要： PROBLEM TO BE SOLVED: To reduce or remove dioxins or the like in exhaust gas to a level satisfying regulatory standard value in a melting process using a large amount of iron-based scraps. SOLUTION: The copper content of a melt is kept at 0.12 mass % or less by using in a melting furnace the iron-based scraps of a low Cu content selected in advance. (1) By preheating the iron-based scraps by the exhaust gas, coarse particle dust having a high Cu content in the exhaust gas is captured and removed at a scrap side, and (2) on a downstream side of the exhaust gas of the melting furnace and a preheating furnace the coarse particle dust of a high Cu content is removed by a primary dust precipitator, or (3) the exhaust gas is cooled quickly after being burned completely in a combustion tower and kept at a high temperature. At the time of being subjected to dust collection by the dust precipitator a fine particulate powder is blown at a front face of the combustion tower or a front face of the dust precipitator so as to reduce an average Cu content in the exhaust gas.

摘要： PROBLEM TO BE SOLVED: To remove and recover dioxins and the like in exhaust gas while avoiding troubles of facilities due to fluctuation of the composition of exhaust gas without burning the exhaust gas containing a large amount of latent heat constituents produced in a scrap melting furnace and a preheating furnace using a large amount of fossil fuel. SOLUTION: The exhaust gas produced in the iron-based scrap melting furnace 1 or the preheating furnace 2 is subjected to a primary dust collection by a hot gas cyclone 3, then cooled indirectly in an indirect cooling tower 4, and is further subjected to dust removal in a main dry dust precipitator 5 so as to remove dioxins and the like at a low temperature. Then exhaust gas recovery is carried out. The composition of the exhaust gas produced in the melting furnace or the preheating furnace is analyzed and if the exhaust gas is reductive, dust collection is performed by the main dry dust precipitator 5 and if the exhaust gas is oxidative, dust collection is performed by a dry dust collector 6 for bypass purpose. A wet dust collector such as Venturi scrubber or the like can be used as the dust collector for bypass purpose in place of the dry dust collector 6.

摘要： PROBLEM TO BE SOLVED: To surely recover removed slag, to facilitate carry-out work of the recovered slag and to enable removal of the slag in the case of sticking a large quantity of hard slag or even in the case of differing the outer diameters of immersion tubes, at the time of removing the slag stuck to the immersion tube in a vacuum and reduced pressure refining apparatus. SOLUTION: The slag 11 stuck to the immersion tube 10 in the vacuum and reduced pressure refining apparatus is removed by integrally elevating/ lowering an edge 2 and a chute 3, and recovered in the chute 3. The recovered slag is stored by dropping into a hopper 5 at the lower part from the opening hole part 4 at the center of the chute 3, and the slag stored in the hopper 5 is carried out together with the hopper 5 and threw out. Further, according to the sticking condition of the slag 11 to the immersion tube 10, the slag from the outside to the inside is removed in order while adjusting the slag removing diameter by changing the position of the edge 2.
