摘要： PROBLEM TO BE SOLVED: To provide a method and equipment for manufacturing a thin metal strip wherein the dimension of a gap between a nozzle and a cooling roll can be exactly measured during pouring molten metal in manufacturing a thin metal strip and a thin metal strip of which the lengthwise thickness is uniform can be manufactured. SOLUTION: A tundish 11 and a cooling roll 15 are set so that the lateral end face of the nozzle 12 of the tundish 11 and the lateral end face of the cooling roll 15 may be within the same plane. The gap 17 is pictured in a large magnification by a CCD (charge coupled device) picturing apparatus 18 with an infrared-transparent filter 19. 1400 deg.C molten metal is held in the tundish 11 and the nozzle 12 becomes incandescent. The shortwave length part is cut away from light emitted from the nozzle 12. The lateral end face of the nozzle 12 and the lateral end face of the cooling roll which does not exceed 200 deg.C are clearly pictured owing to an adequate contrast ratio. The dimension of the gap 17 is exactly measured by this image processing so that the thin metal strip with a lengthwise uniform thickness is manufactured stably.

摘要： PROBLEM TO BE SOLVED: To shorten a tact time for a dewaxing process and prevent a combustion chamber from being hardly contaminated by a method wherein when the dewaxing process time is twice that of sintering and cooling process time, for example, a first dewaxing chamber and a second wax processing chamber are connected in parallel with a transporting chamber. SOLUTION: Some processed substances S are loaded from a loading port 5 into a transporting chamber 1, alternatively transported to a first wax chamber 2. and a second wax chamber 2. and processed there. Then, the processed substances S are taken out to the transporting chamber 1, transported from the transporting chamber 1 into the sintering chamber 3, sintered there, and then they are cooled at a cooling chamber 4 and discharged out of a discharging port 6. The dewaxing process requiring the time of about twice as compared with that of each of the sintering and the cooling is performed in parallel in the first wax chamber 2. and the second wax chamber 22 with a time displacement of 1/2 cycle, resulting in that each of the processing chambers is operated without generating any loose time. In addition, since the sintering chamber 3 is spaced apart by the transporting chamber 1, no contamination is made by the wax vapor.

摘要： PURPOSE:To enable rapid cooling to a material to be treated and to obtain a steel having good quality by arranging gas introducing holes for cooling to a heating chamber and a cooling chamber, respectively, means for controlling cooling degree in the cooling means and a bypass gas circuit as openable/ closable for connecting the heating chamber with the cooling chamber. CONSTITUTION:The material 3 to be treated is conveyed to the cooling chamber 24 and after evacuating the air, this is conveyed to the heating chamber 23, and while evacuating with an evacuating pipe 7b, this is heated to the prescribed temp. with a heater 10. Until heating treatment completes, by opening valves 26 and 8, argon, etc., is introduced and pressure is raised to about 2kg/cm G. When the prescribed heating treatment completes, by quickly opening a valve in the bypass pipe 30, pressures in the heating chamber 23 and the cooling chamber 24 are equalized. Successively, by quickly opening a gate valve 22, while conveying the material 3 to be treated to the cooling chamber 24, a cooling fan 14 is rotated at first in a small number of revolutions and at the time of perfectly closing the gate valve 22 after conveying the material 3 to be treated, this is rotated in the prescribed number of revolutions to quickly execute the cooling.

摘要： PURPOSE:To efficiently remove the oil steam, etc., generated from works by flowing gases from the upper to the lower part of the and works from an outlet door side to an inlet door side. CONSTITUTION:The works 16 are mounted on a carrier frame 9. These frames are carried by each one unit from the inlet door 3 into the device where the frames are transported by trucks 8a to 8d and are so installed that the plate surfaces of the works 16 parallels with the inlet door 3 or the outlet door 4. The inlet door 3 is closed and while the gases are kept discharged from a discharge port 12, the carrier gases are introduced from introducing ports 11a to 11e. The gases flow from the upper introducing ports 11a to 11e to the lower part and flow from the outlet door 4 toward the discharge port 12 near the inlet door 3. The fats, oils, etc., sticking to the works are efficiently removed when the works 16a to 16h are heated by energizing heaters 14a, 14b, 15.

摘要： PURPOSE:To uniformly cool a material to be treated with scarcely developed strains by providing a vacuum heat treatment furnace composed of a cooling chamber, in which the cooling gas flows, and a rotating mechanism for cooling while rotating the heated material to be treated at high temp. in this cooling chamber. CONSTITUTION:Compressed air is introduced into a cylinder body 22 and the air cylinder is driven to heat the material 15 to be treated, set in the heating chamber 1 to prescribed temp. Successively, the material 15 to be treated is set between guide plates 9a and 9b in the cooling chamber 2. After that, a gate valve 3 is closed and gas is introduced 16 into the chamber 2 to attain 600-2000Torr pressure in the chamber 2. Then, after introducing the gas, an air motor 28 is driven and the material 15 to be treated is rotated in the chamber 2, and also a fan 7 for cooling circulation is driven to circulate the gas in the chamber 2. During this, after exhausting the gas cooled with a heat exchanger 8 from a fan 7, the gas is passed through between right and left side walls in the chamber 2 and the guide plates 9a, 9b and blasted against the material 15 to be treated during rotation in the chamber 2 to cool the material 15 to be treated at high temp. state.
