摘要： PURPOSE:To improve responsibility, eliminate the production of gas in a radiation thermometer observation channel and make exact measurement by unitizing an endurance component of a remote measurement device and providing a cooling channel and a cooling clamber therein. CONSTITUTION:A radiation thermometer device comprises an inner pipe 7 composed of a remote measurement device 6 and an alumina porcelaneous pipe and an outer pipe 8 made of alumina graphite. In a case where the inner and outer pipes 7, 8 are consumed, the inner pipe 7 and/or the outer pipe 8 can be easily exchanged for the device 6 and the device 6 can be repeatedly used as an endurance component. A refrigerant supply opening 32 such cooling air is provided in an amplificaytion box 24 and supplied refrigerant passes a refrigerant flow passage 33 formed in a heat resistant flexible tube 12 through the inside of the amplification box 24. Thereby heat resistant fiber 11 and an optical system setting part 9 can be always surely cooled and normal temperature measurement is made possible.

摘要： PROBLEM TO BE SOLVED: To provide a continuous casting method for manufacturing a cast slab, in which the shape of the short side of the cast slab is measured or predicted and the bulging volume of the cast slab is controlled on the basis of the measured or predicted value.
SOLUTION: In the invented continuous casting method for manufacturing the cast slab, a measurement or prediction is made of the profile line of the cross-sectional shape of the short side of the cast slab extracted from a casting mold. A line connecting both ends of the profile line is defined as the reference line. The average deformation volume of the short side of the cast slab is determined on the basis of the reference line and profile line. If the average deformation volume is above the upper limit, one or more of the following control steps is or are performed: a step of increasing the inclination angle of the short side of the casting mold in reference to the casting direction, a step of increasing the volume of cooling water in a cooling zone just below the casting mold, or a step of decreasing the casting speed. If the average deformation volume is below the lower limit, either or both of the following control steps is or are performed: a step of decreasing the inclination angle of the short side of the casting mold in reference to the casting direction, or a step of decreasing the volume of cooling water in the cooling zone just below the casting mold.

摘要： PURPOSE:To reduce line resistance at the time of light rolling reduction by equalizing clamping force of segment at upstream side of crater end part with sum of molten metal static pressure and rolling reduction reaction and balancing the clamping force at downstream with pinch roll reaction. CONSTITUTION:Each segment 22 has upper and lower frames 1, 2 and supports the upper and lower rolls 10, 11, respectively, and also positioning for clamping the upper frame 1 is executed with the piston rod in oil hydraulic cylinder 9. At the time of applying the light rolling reduction to the cast slab 17, at the upstream side of the crater end (k), the clamping force of the segment 22 is set so as to almost equalize with the sum of the molten metal static pressure and the rolling reduction reaction, and at the downstream side thereof, the clamping force is set so as to balance with the reaction of the pinch rolls 18, 19. As the clamping force of the segment in the unnecessary range of rolling reduction to the cast slab. After light rolling reduction range can be reduced to the limit, which the upper frame 1 is not floated up, the line resistance is reduced to the min. limit.

摘要： PURPOSE:To improve stirring efficiency and to permit the easier passage of a dummy bar by forming plural ingot passage ports with two pieces of inductor iron cores facing each other and providing a switch device between both iron cores. CONSTITUTION:The inductor iron core 18 and the inductor iron core 1 on one side are disposed to face each other and the switch device 13 is provided to the top end on the open side of the core 1. Coils 2-8 are further wound on the respective sides of the cores 1, 18 to constitute an inductor 19. The cores 1, 18 are separated by opening the device 13, by which the interference of a connecting arm 17 of the dummy bar 15 and the coil 5 is prevented and the passage of the dummy bar 15 is made easier. The ingot passes respectively through the port enclosed of the windings 5, 6, 7, 8 and the port enclosed of the windings 2, 3, 4, 5 when the device 13 is closed by the above-mentioned method. The molten steel stirring effect in the ingot is thus improved.

摘要： PURPOSE:To prevent flowing-out of slag from a ladle by setting bar-like body, which has sp. gr. larger than that of molten steel and is possible to engage with upper part of molten steel discharging hole, ascending/descending the bar-like body and enabling measurement of the position in perpendicular direc tion and hanging force. CONSTITUTION:Molten steel flow rate from the molten steel discharging hole 12 at the bottom part of the ladle 10 is adjusted with the flowing rate adjusting means 14. Length of the bar-like body 18 is made to more than the molten steel depth developing vortex flow in the molten steel 16 and shape is made to engage with the upper part of the molten steel discharging hole 12 and the sp. gr. in made to larger than that of the molten steel. The bar-like body 18 is ascended/descended with ascending/descending means 20. Further, position of the bar-like body 18 in the perpendicular direction is measured with a position measuring means 22. Then, the hanging force of the bar-like body 18 is mea sured with a hanging force measuring means 24. By this method, the yield of steel can be improved.

摘要： PURPOSE:To obtain air-permeable refractory which is little in dispersion of strength and permeability, and excellent in spalling resistance and corrosion resistance by mixing the prescribed amount of graphite powder with a refractory raw material having specified composition and furthermore adding organic fiber. CONSTITUTION:A refractory raw material which is constituted of mullite, baddeleylite and corundum as a main mineral phase and has chemical composition of 25-85wt.% Al2O3, 10-70wt.% ZrO2 and 5-25wt.% SiO2 is prepared. Then air-permeable refractory is produced by mixing 30-60wt.% refractory raw material, 10-30wt.% graphite powder and organic fiber (e.g., polyester fiber, nylon fiber) with a necessary additive such as a binder. This obtained air-permeable refractory is preferably utilized especially for gas babbling in continuous casting of steel and stable babbling is enabled because deterioration of permeability due to heating is not almost caused.
