CONTINUOUS MACHINE FOR CASTING THIN-WALL TUBES BY FREEZING Russian patent published in 1999 - IPC

Abstract RU 2133171 C1

FIELD: casting of large-diameter thin-wall tubes. SUBSTANCE: machine has first and second level drawing mechanisms for drawing up tubes. First level mechanism has proximate and distant petal-type lifts connected to actuating mechanisms through bars lowered below rocking mechanism. Tube lifts of second level drawing mechanism are connected with actuating mechanisms disposed on rotary drive mechanism. Lifts convey tube to rotary mechanism by means of bars. Tube is moved to horizontal position by means of turnover. Tubes may be transported even when material is in temperature-unstable state. EFFECT: increased efficiency and improved quality of tubes. 5 dwg
