METHOD TO WORK METAL IN THE PROCESS OF CONTINUOUS CASTING AND A DEVICE TO IMPLEMENT IT Russian patent published in 1995 - IPC

Abstract RU 2034679 C1

FIELD: metallurgy. SUBSTANCE: in the process of metal working when casting continuously the metal is fed from casting ladle into vacuum chamber, then the metal is worked in the vacuum chamber, the metal through a separate pipe branch is fed into intermediate ladle and than into crystallizers, as well as metal is deoxidized and alloyed, in doing so, first the metal is fed into the first part of the vacuum chamber, where jet-type evacuation is performed, then the metal is fed into the second part of the vacuum chamber, where the metal is deoxidized and alloyed by feeding deoxidizing agents and alloying elements into this part of the chamber. Then the metal is fed from the second part of vacuum chamber into the intermediate ladle using an additional pipe branch. Once metal level in the intermediate ladle has risen over lower ends of pipe branches, and vacuum chamber has sealed by liquid metal, the circulating evacuation of the metal placed in the intermediate ladle is performed through inert gas feeding in a pipe branch, and once residual pressure has been set in the vacuum chamber, circulating evacuation is additionally carried out in the intermediate ladle along with metal working. The device to work metal in the process of continuous casting has a vacuum chamber with drainage pipe branch. The vacuum chamber is subdivided by a partition into two communicated parts. One chamber part is provided with two drainage pipe branches, as well as inlet sluice seal. EFFECT: high productivity. 2 cl, 1 dwg
