SINGLE STRAND SCREW MACHINE FOR DEPOSITION OF HOT METAL COATINGS ON PIPES Russian patent published in 2004 - IPC

FIELD: metallurgy; deposition of hot metal coatings on pipes. SUBSTANCE: the invention is dealt with metallurgy, in particular with the equipment for production of pipes with metal coatings - a single-strand screw-type machine for deposition of hot metal coatings on pipes. The machine has a bath for melt, a device for loading pipes, immersing screws with adjustable guides, a mechanism for rising the front end of pipes that consists of a hook-type bite, a crank, a lever, an elastic compensator, drawing magnetic rollers and a ring type blowing nozzle. The immersing screws are rotating continuously by the drive with a transmission shaft. The hook-type bite is kinematically linked with the immersing screws and is moving with stops in its upper and lower positions. The lifting and sinking of the lever with the mounted on it hook-type bite is exercised by the continuously rotating crank. In the result the invention ensures an increase of productivity of the machine. EFFECT: increased productivity of the machine. 4 cl, 3 dwg
