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 eliminate inefficiency accompanied by removal by forming a castable refractory layer between an upper frame and a lower frame provided at a lower end of a hanger brick in a construction comprising the upper frame made up of a fireproof heat insulating plate fitted into the hanger brick hanging on a furnace frame. CONSTITUTION:A mounting groove 31 is provided to mount an upper frame 41 at an upper frame mounting position of a hanger brick 3 mounted on a furnace frame 1 through a mounting metal 2. With an upper frame 41 fitted into the mounting groove 31 of the hanger brick, the hanger brick 3 is mounted on the furnace frame 1 with the mounting metal 2. A lower frame 5 is mounted at a lower end of a hanging bar 12 fixed on the furnace frame 1 with a mounting nut 13. A castable refractory 10 flows between the upper frame 41 and the lower frame 5 to form a ceiling construction. This eliminates the need for removing the upper frame 14 comprising a heatproof heat insulating plate after the solidification of the castable refractory thereby allowing the use of the upper frame 41 as heat insulating layer for the ceiling.

摘要： PURPOSE:To undefine the structure of refractory and elongate the life of the same, by a method wherein the title lining is constituted two or more pieces of anchor fittings, fixed between a lib and another lib which are fixed to a steel skin, and undefined refractories, fixed to the anchor fittings. CONSTITUTION:Refractory bricks 12 are applied to a site (at the side of a tapping hole) contacting with molten steel while undefined refractory 14 is applied to the site except the site at the side of the tapping hole through spraying technique while the undefined refractories 14 are fixed by anchor fittings 18 welded and fixed to libs, welded to a steel skin 15 in the inside of the refractories 14. The anchor fittings 18 will never be welded to the steel skin 15. The anchor fitting 18 is constituted of a round steel rod 20 and a plurality of Y-studs 22 welded and fixed to the round steel rod 20. The structure of the permanent lining consisting of the monolithic refractory may be improve remarkably by only contriving to attach the anchor fittings while an excellent effect may be developed when this method is applied to the site of a furnace ceiling having the problems of dropping and/or separation especially.

摘要： PURPOSE:To easily and rapidly repair the entire part of the damaged part of the bottom bricks of a bottom blown furnace by charging brick scrap to the damaged peripheral brick part of a bottom blowing furnace and opening a force-feed hole of the press-feed hole bricks stacked in the central part of the furnace bottom, then force-feeding castable refractories through this hole. CONSTITUTION:A pipe 6 which is made of steel such as stainless steel and into which refractories 7 are previously packed is embedded into the bricks to form the force-feed hole bricks 5. The force-feed hole bricks 5 are previously stacked in the central part of the bottom of a converter, which consists of a shell 1, permanent bricks 2 and wear bricks 3 and is provided with bottom blowing tuyeres 4 penetrating the tuyere bricks 3a, in such a manner that the above-mentioned steel pipe 6 penetrates the furnace to the inside and outside thereof. The tuyeres 4 are replaced and the press-feed hole is opened by boring in the above-mentioned refractories 7. The brick scope 8 is further charged as aggregate from the upper part of the converter to the damaged peripheral brick part of the tuyeres 4. The castable refractories 9 are then force-fed from the force-feed hole to pack the spacing of the brick scrap 8.

摘要： PURPOSE:To repair the shaft part of a blast furnace in a way as to provide long durability and high reliability to said part by heating up and sintering the repair material sprayed on the repair position in said part by the fire generated when oxygen is blown to the coke in the furnace. CONSTITUTION:A repair material 2 which is a refractory material is sprayed onto the shaft part 1 of a blast furnace under blowing-down where the brick is dislodged. The stock line of the coke 3 charged into the furnace under said material 2 is risen after suitable time for curing and oxygen is blown from a furnace window 4 through a pipe 5. The coke 3 near said part is then burned and the material 2 is heated up and sintered by the coke flame. The refractories having high strength are thus obtd. and repairs providing for long service life is accomplished.
