DEVICE FOR CONTINUOUS CASTING Russian patent published in 1995 - IPC

FIELD: foundry engineering. SUBSTANCE: device has crystallizer made up as endless flexible belt with filters and vacuum valves, crystallizer evacuation system and crystallizer moving drive. Belt is lined with fireproof material by means of vacuum-film forming method and covered with synthetic film. Crystallizer evacuation system is constructed as flexible vacuum cable fixed along endless flexible belt, drum connected with rarefying resource, and unit controlling valves switching rarefying from flexible vacuum cable to endless flexible belt filters. Flexible vacuum cable has drum connecting pipes and regulated valves for coupling endless flexible belt filters with flexible vacuum cable. Unit controlling valves switching rarefying from flexible vacuum cable to endless flexible belt filters is constructed as immovable guiding plate which replaces rod rolls movable simultaneously with crystallizer. Rolls open plugs of controlled valves. Drum connected with rarefying resource is constructed driven. Vacuum cable is a drawing member and endless flexible belt is a load carrier. Usage of belt fixed vacuum cable and drum providing rarefying into flexible vacuum cable reduces quantity of valves (pipes) connecting crystallizer with outer vacuum resource. This simplifies device design and increases its safety in operation. Large-sized movable pipe lines with switching valves are unnecessary. Mechanical controlling of valves also simplifies device design. EFFECT: simplified design, increased safety. 3 cl, 4 dwg
