METHOD OF DUST CATCHING DURING CASTING MOLDS KNOCK-OUT ON KNOCKING-OUT LATTICE AND KNOCKING-OUT LATTICE COVER Russian patent published in 1994 - IPC

FIELD: metallurgy. SUBSTANCE: method provides for covering of knocking-out lattice casing openings whole area with foam during molds knock-out procedures. Foam is fed in the openings zones constantly and thickness of the foam cover is regulated by preliminary mounting of reinforcing curtains-lattices. To cover the openings the casing has a foam generation system, including foam generators. The openings have two row curtains, made of flexible members, an aspiration system, made in the form of a side sucking panel, located along one side of the casing, and a pipeline with nozzles, located on the other side. Slot type tips of the foam generator, the side aspiration system and the pipeline for compressed air feeding ate mounted in a side wall of the casing with outlet holes of the slot tips of the foam generator, of the side aspiration system sucking branch pipe and the compressed air pipeline nozzles placed inside of the casing. The slot type tips, the side aspiration system and the pipeline have are provided with flanges on outer surface of the casing to be connected to general systems of foam generation, aspiration and compressed air feeding. EFFECT: method provides dust catching during molds knock-out on knocking out lattice. 3 cl, 4 dwg
