摘要： PURPOSE:To heat both end parts of a strip with a little electric power and to improve the strip quality by installing a couple of laterally movable suspended frames from an overbridge type gantry on the pass line between hot finishing rolling mills and installing a couple of induction heaters being vertically movable on the inside face of the frames facing each other. CONSTITUTION:Carriers 2a movable in the width direction on an overbridge type gantry 1a on the pass line between hot finishing rolling mills. Intermediate movable frames 5a and 5b, which are vertically moved by cylinders 12a, 12b and a distance between the frames 5a, 5b is adjusted by a gap setting cylinder, are installed on the inside face of a couple of vertical frames 2b facing each other. The frames 2b are suspended from the carriers 2a. The frames 5a, 5b are provided with heating faces 6c, 6d vertically moved by copying cylinders 9a, 9b. The heating faces 6c, 6d to which a steel strip 22 exists hold a proper gap against the strip 22 by actions of the above cylinders 9a, 9b. End parts of the strip 22 are heated with a temp. rise of the heating faces 6c, 6d by induction heating inductors 15a, 15b. Therefore, the rolling quality of the rolled strip 22 whose both end parts are easily cooled is made to be uniform and good.

摘要： PURPOSE:To prevent oxidation of an article to be heated by supplying inert gas in a heating coil, and providing a gas sealing injection ring and an air involving preventing ring. CONSTITUTION:An article 1 to be heated is fed on a transfer conveyor 2, and pressure-fed to a heating coil 4. In the coil 4, an inert gas from a gas supply nozzle 9 is supplied, and the gas is jetted in the coil 4 from jetting rings 13, 14. In addition, compression air which is the same in quality with the inert gas fed from jetting rings 11, 17 to the jetting ring 13, 15 is jetted toward the outside of the coil 4, whereby instruction of air into the coil 4 is prevented. At this time, a regulation valve 10 is regulated to minimize the flow out of the inert gas. It is thus possible to heat the article 1 in a state where its oxidation is restrained in the atmosphere of inert gas and then to allow the transportation to a post-process.

摘要： PROBLEM TO BE SOLVED: To effectively and securely melt an ash fraction with excellent corrosion resistant, heat resistant, and simplified structure, and realize turning-up and turning-down of a furnace in a short time. SOLUTION: An ash melting furnace body 27 is formed with a heat resistant and corrosion resistant ceramics tapered tube 27a, so that an ash fraction is made slag without a high temperature reaction with a CaO component of the ash fraction, and a furnace inner wall 27d is effectively prevented from being damaged. Thus, spalling resistance is improved, and starting-up and stopping of the furnace are realized in a short time. Further, molten slag 21 is effectively discharged, and complete decomposition of harmful substances in a secondary combustion chamber 28 and combustion heat in the same chamber 28 are effectively utilized.

摘要： PURPOSE:To prevent the thin films formed on a shutter and shielding plates by forming the shutter and shielding plates of materials which have the same coefft. of linear expansion as the coefft. of expansion of a material to be deposited by evaporation or the coefft. of thermal expansion approximate thereto and are specified in vapor pressure. CONSTITUTION:The vapor of Ti 12 is ejected from the nozzle of a crucible 11 and is made into cluster ions 12a, 12b which head together with the gaseous N2 ejected from a gas nozzle 18 toward a substrate 1. These ions deposit by evaporation on the shielding plates 44 and the shutter 41 and form the thin films of Ti and TiN. The materials of the shielding plates 44 and the shutter 41 are formed of the materials having the coefft. of linear expansion as the coefft. of linear expansion of the thin films deposited by evaporation or the coefft. of linear expansion approximate thereto to prevent the peeling of the formed in films by the effect of heat. The vapor pressure of the materials of the shielding plates 44 and the shutter 41 is set as low as Torr at 200 deg.C to substantially prevent the evaporation in a vacuum. As a result, the intrusion of the peeled thin films as contaminations into the TiN films formed by vapor deposition on the substrate 1 is lessened.

摘要： PURPOSE:To shorten the time for heating and cooling a crucible and to improve the capacity to produce org. thin-film substrates by holding heating wires enclosing the crucible with a cylindrical part in contact with the crucible and disposing a water cooling jacket so as to enclose this cylindrical part. CONSTITUTION:The inside of a vacuum chamber 1 is evacuated to a prescribed vacuum degree and the crucible 3 is heated to evaporate a material 5 to be deposited by evaporation. The vapor is injected from a nozzle 4 to form clusters 8. The clusters 8 are partly ionized by the electron beam released from an ionizing filament 10 to form the ionized clusters 14. These clusters are accelerated together with the clusters 8 by a grounding electrode 15b to form the thin film on the surface of the substrate 16. The heating wires 30 are disposed to enclose the crucible 3. The heating wires 30 are held by the cylindrical part 31 disposed to come into contact with the crucible 3 and the water cooling jacket 32 is disposed to enclose this cylindrical part 31 in contact therewith. As a result, the time for heating up the crucible 3 and the time for cooling the crucible 3 at the end of the operation are shortened.
