IPC: F25B9/14
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To reduce an occupied space of a gas compressing/expanding device while heat-radiation efficiency of compressed working gas is raised. SOLUTION: A compressing part 50 and an expanding part 30 are provided side by side and fixed to a driving part 20.

Title: Refractory nozzle having seal structure
Inventor: UENO KAZUYUKI
IPC: B22D11/10
Filed: 1992-12-17
Abstract: PURPOSE:To prevent invasion of the outside air from a body part of a refractory body of a long-sized nozzle by providing an enclosed chamber which approximately surrounds the molten metal flowing through the nozzle hole in the body part of the nozzle body toward the center of an extraction hole by the prescribed space away from the outer circumferential surface of the nozzle body. CONSTITUTION:Invasion of the outside air into an extraction hole is completely prevented by keeping the pressure of an enclosed chamber 4 lower than the pressure in the extraction hole of the molten metal during the casting operation. When the enclosed chamber is closely located to the outer circumference, the outside air is sucked through the pores in the outer circumferential surface, and the vacuum of the enclosed chamber 4 can not be maintained, and it is necessary to keep the clearance between the enclosed chamber 4 and the body part of the nozzle body 1 to be 10mm or over. In order to maintain the pressure of the enclosed chamber 4 to be 700-380 Torr., the average permeability is suppressed to be 60m10<-5> cm<3>.cm/cm<2>.cmH2O.sec or less on the nozzle hole side, and 20X10<-5>cm<3>.cm/cm<3>.cmH2O.sec or less on the outer circumference side, taking into consideration the suction passage and the suction port. Thus, the increase of oxide inclusions and generation of defects by bubbles are prevented, and the reduction of the nozzle blockage during the casting operation is also released.
