SOLUTION: The smelting furnace, separating furnace and copper refining furnace are continued and integrally connected and operated as a continuous copper-making equipment. The molten material temp. in the furnace 230 is quasi-continuously measured with an immersion consuming type optical fiber thermometer. An optical fiber 220 of the optical fiber thermometer is fed out from an accommodating part 221 through pinch rollers 222. The tip part of the optical fiber 220, through a guide 240, is dipped into the high temp. molten material 210 in the furnace 230 to measure the temp. with a temp. detector 260. The tip part of the optical fiber 220 denitrified by the molten material 210 is cut off with a cut-off means 250 so that the temp. measurement can again is executed. The temp. of the molten material is kept at 1210±10 deg.C.

摘要： PURPOSE:To automatically execute the detection of a push-up rod produce from the bottom surface of a mold, to reduce the burden of a worker and to improve the working efficiency by detecting come-out/in of a detecting rod arranged to be freely come out/in to the lower end surface of the detector body, from the lower end surface. CONSTITUTION:At the time of abutting on the bottom surface of the mold by descending the detector body 12, in the case the push-up rod 5 does not protrude, the detecting rod 13 is abutted on the bottom surface of the mold and retreated to the detector body 12, and it is detected by the detecting mechanism that the push-up rod 5 is not protruded. On the other hand, in the case the push-up rod 5 protrudes, the lower end surface of the detector body 12 is bumped to the push-up rod 5 and is not brought into close contact with the bottom surface of the mold, and gap is generated between both. Therefore, the detecting rod 13 becomes the protruding condition from the lower end surface of the detector body 12 and the detecting mechanism detects that the push-up rod 5 is protruded. Therefore, without any trouble to the worker, the protrusion of the push-up rod 5 can be detected.

摘要： PROBLEM TO BE SOLVED: To promote the dissolution of magnetite of the slag in a copper making furnace forwarded to a smelting furnace. SOLUTION: In the method for operating the copper making equipment which has the smelting furnace 1, a separating furnace 2 and the copper making furnace 3 and forwards the slag formed in the copper making furnace 3 to the smelting furnace 1, the slag S formed in the smelting furnace 1 is sampled and the concentrations of the respective components of the magnetite existing in the solidified structure of the slag S are analyzed, by which whether the magnetite is the magnetite existing in the slag S formed in the copper making furnace 3 or the magnetite deposited from the lag S formed in the smelting furnace 1 is discriminated. When the magnetite is discriminated to be the magnetite existing thus far in the slag S formed in the copper making furnace 3, the operation conditions of the smelting furnace 1 are shifted to the conditions under which the magnetite is more easily meltable in the smelting furnace.

CONSTITUTION:After pouring molten metal into a mold 2 in a rotary table 1 and cooling, the anode 3 is pushed up by a pushing-up rod. In the case this anode 3 is defective, by shifting the travelling truck 13, both side edges of the anode 3 are champed by an abutting plate 303 of a supporting arm 301 in a holding mechanism 30. By using a lifter 20 by a lifting cylinder 17, the anode 3 is held up. The anode 3 is inclined at a prescribed angle by the pushing-up rod, but as a gravity center of the anode 3 is shifted to a guide roller 304 side from the abutting plate 303, the anode is rotated around the center of the abutting plate 303 as a fulcrum according to holding-up of the anode 3, and abutted on the guide roller 304 and becomes horizontal condition.

摘要： PROBLEM TO BE SOLVED: To provide a magnesia-spinel refractory having improved spalling resistance, and significantly improved corrosion resistance and slag penetration resistance. SOLUTION: The magnesia-spinel refractory has a combined structure composed of periclase having closed pores of the pore diameter of 1-5 μm and spinel comprising a MgO-Al 2 O 3 component. The periclase crystals have a uniform size, and the crystal grain boundaries have a spinel phase. The mixture of magnesia and alumina contains the powder of one of the components and a granulated powder of the other component, or the granulated powders of both components. It is preferable to use a spray dryer method as a granulating means, and a hydrostatic pressing method as a molding means. These mixtures are used for producing a magnesia-spinel protecting tube and crucible, bricks for copper smelting furnace, and the protecting tube and crucible for copper smelting furnace slag. In that case, the hydrostatic pressing method is used. COPYRIGHT: (C)2011,JPO&INPIT
