摘要： PURPOSE:To quickly carry bricks toward a furnace bottom one by one with a simple operation by combining an extendable brick receiving arm and a brick sucking tool and operating it. CONSTITUTION:A pallet 72 loading many bricks 71 for furnace bottom is carried on a roller conveyor 23 in a carrier 10. By extending the extendable brick receiving arm 6 fitted to a floor frame 4, one piece of the brick 71 is shifted to the arm 6 from the pallet 72. By swinging the arm 6 and turning this downward, the brick 71 on the arm 6 is sucked with a suction cup in the brick sucking tool 13. The brick sucking tool 13 is operated with a swinging crane 12 and the suck-supported brick 71 is carried to brick laying position in the furnace bottom. The carrier 10 is lifted by the thickness of one piece of the brick, and as mentioned above, the most upper step of brick is carried one by one toward the furnace bottom direction.

摘要： PURPOSE:To prevent the corrosion of a lining material without deteriorating refining characteristics by adding alumina and/or lime to molten slag to increase the viscosity of the slag. CONSTITUTION:When molten iron is desulfurized and dephosphorized with a sodium-base treating agent, 2-30wt% powdery alumina and/or 2-10wt% powdery lime is added to molten slag basing on 100wt% molten slag. The viscosity of the molten slag is increased to inhibit the penetration of the slag into the structure of a lining material and to reduce the rate of corrosion. Bauxite, sintered alumina or the like is used as said alumina, and limestone, calcined lime or the like as said lime.

摘要： PURPOSE:To easily repair a converter lining by kneading refractory powder with molten tar; granulating the kneaded material; mixing the granules into a spraying material; and spraying the mixt. upon the damaged parts of the lining material. CONSTITUTION:Molten tar is uniformly mixed with 40-60 wt% of fine grains of above 75% MgO-contg. magnesia type refractories with a diameter below 1 mm. The mixt. is kneaded well and granulated to a diameter of 1-5 mm. Refractories such as dolomite clinker and Cr ore may be used in combination with the above refractories. 20-40 wt% of the granules is mixed with 20-40 wt% of refractories, crushed to a diameter of 0.5-3.0 mm, which are of the same quality as the refractories such as magnesia, dolomite clinker and Cr ore in the granules, 30-50 wt% of below 0.3 mm fine powder of the refractories and 0.5 wt% of a binder such as sodium silicate to the total wt. This mixt. is sprayed upon the damaged hot parts of a converter lining material to repair the parts.

摘要： PURPOSE:To shorten high temp. operating time without developing any dust and to obtain repaired material having closeness and high stuck force by beforehand packing drying type water-incorporated burning material into upper-top opening type doughnut-state metallic frame, inserting a heating-state RH submerged tube in the metallic frame and repairing part to be repaired in the RH submerged tube. CONSTITUTION:The doughnut-state metallic frame having size corresponding to this part to be repaired in the RH submerged tube is prepared and the drying type water-incorporated burning material is beforehand packed to this. Successively, this doughnut-state metallic frame is set below the RH submerged tube and the RH submerged tube is inserted into the doughnut-state metallic frame. At this time, the RH submerged tube may be in a heating condition, and after inserting for about 30sec.-15min, this is pulled up. The drying type water- incorporated burning material stuck to the RH submerged tube in such way is dried by utilizing the heat of RH submerged tube. Then, the drying type water-incorporated burning material contains about 40-90 wt. parts of refractory material and about 10-60 wt. parts of compound containing about 30wt.% water of crystallization, and as the refractory material, alumina, etc., is used.

摘要： PURPOSE:To prolong the life of a vessel for molten pig iron and to reduce the number of lining the vessel while suppressing a heat loss from an iron plate, in the pretreatment of the molten pig iron such as desilicating, by using double- layered formed bricks having high durability and low thermal conductivity as the lining of the vessel for the molten pig iron. CONSTITUTION:The whole inside surface of an iron plate A covering the entire periphery of a torpedo car 5 except its opening 5a to receive molten pig iron is lined with castable B in the same way as a conventional manner. The further inward part is lined with roof-forming double-layered bricks C at the ceiling part, with double-layered formed bricks D for a slag line at the part estimated to correspond to the slag line during reserving the molten pig iron and with pieces of bricks E for the part of the molten pig iron at the other part, respectively. The bricks C and D are those formed by integrating the two layers of a refractory material alpha excellent in durability to the pretreatment of the molten pig iron and another refractory material beta having thermal conductivity below 3Kcal/m.h. deg.C, and applied in a manner such that the layer alpha is located at the working side while the layer beta is located at the side of the iron plate A.

摘要： A method of producing carbon steel and low-alloy steel in a basic oxygen furnace is disclosed, in which a blow of the bottom-blowing gas predominantly comprised of carbon dioxide is introduced into a molten metal through at least one nozzle provided in the bottom or side wall of said basic oxygen furnace at least partly during the period of time from the beginning of blowing to the tapping of the melt, and the flow rate of the bottom-blowing gas is 1/200 - 9/200 the rate of oxygen impinged upon the melt through a lance. A steel making apparatus adapted to carry out the above-mentioned novel method of producing steel is also disclosed, which comprises, in combination, a furnace permitting both top-blowing of pure oxygen and bottom-blowing of a gas mainly composed of carbon dioxide, means for collecting the waste gas generated from the furnace, means for mixing the waste gas with oxygen and/or steam, means for burning the mixture thereof, and means for injecting the resulting combustion gas into the molten metal within said furnace.
