  • Publication number: 20160354985
    Abstract: A tire preheating apparatus includes an external preheating portion which surrounds the outside of a green tire having an easy vulcanization region and a difficult vulcanization region, and heats the green tire to a normal temperature or more from the outside of the green tire at a temperature less than the vulcanization temperature at which a vulcanization reaction is promoted in the green tire, and an internal preheating portion which is disposed inside the green tire, and heats the green tire to a normal temperature or more from the inside of the green tire at a temperature less than the vulcanization temperature. The external preheating portion includes a first tire heater which heats an outer surface of the easy vulcanization region, and a second tire heater which heats an outer surface of the difficult vulcanization region at a higher heating value than that of the first tire heater.

  • Publication number: 20130320073
    Abstract: The present invention relates to an impeller manufacturing method in which a thermal cycle is performed on an assembly body with a brazing material formed of a Ni-containing Au alloy being placed at a bond portion of at least two impeller constituent members. The thermal cycle includes a temperature increasing process with a temperature increasing rate of 20° C./hr. to 100° C./hr., the process including a first intermediate retention and a second intermediate retention each keeping the temperature, the first intermediate retention performed in a temperature range of 500° C. to 850° C. and the second intermediate retention performed in a temperature range of 850° C. to 950° C. (but not including 850° C.). In the thermal cycle, the temperature is increased in a temperature range exceeding 950° C. after the second intermediate retention at a rate lower than that before the second intermediate retention.

  • Publication number: 20110277960
    Abstract: The heat transfer performance of a gas cooler provided with a fin tube type heat exchanger is improved. This is a gas cooler 10 which is provided with a heat exchanger 6, cools a gas to be cooled, which is introduced from the outside, by performing heat exchange between the gas to be cooled and the heat exchanger 6, and discharge the cooled gas to the outside. The heat exchanger 6 includes: a plurality of heat transfer fins 8 which are placed side by side via a prescribed gap therebetween, the gas to be cooled flowing through the gap; and heat transfer tubes 7 which pierce through the plurality of heat transfer fins 8 and are provided in a plurality of rows along the direction in which the gas to be cooled flows. The outside diameter do of the heat transfer tubes 7 is 20 to 30 mm.

  • Patent number: 7147033
    Abstract: A twin-drum continuous casting apparatus for casting a metal sheet (4) by supplying molten metal (3) to a pouring basin formed by a pair of cooling drums (1) rotating in opposite directions, and side gates (2), to cool the molten metal (3) by contact with surfaces of the cooling drums (1), thereby forming a solidified shell. The cooling drum (1) is formed from a drum body (11) having shaft portions at opposite end portions, and a drum sleeve (10) fitted on an outer peripheral portion of the drum body (11). Also, means is provided for preventing various adverse influences due to differences in thermal expansion of constituent members of the drum body (11) during casting. Thus, the reliability of the apparatus is increased, and the quality of casting is improved.

  • Patent number: 6371400
    Abstract: A band steel plate winding apparatus comprises a winding drum for winding a band steel plate; unit rolls, and curved surface guides adjacent to the unit rolls, provided along a circumferential surface of the winding drum forwardly and backwardly movably between a winding drum surrounding position and a retreat position, the position of the unit roll relative to the winding drum at the time of entry of the band steel plate being downstream at an angle of about 15 degrees or less from the position of contact between the winding drum and the band steel plate; and ejection nozzles provided in a guide surface of each of the curved surface guides for ejecting a gaseous or liquid fluid at a high speed toward the band steel plate before the band steel plate collides with the curved surface guide. The band steel plate winding apparatus permits high speed winding of a band steel plate while effectively preventing buckling of a front end of the band steel plate, and can avoid a great increase in equipment cost.
