APPARATUS FOR IN-LINE VACUUMIZING OF METAL DURING CONTINUOUS POURING PROCESS Russian patent published in 1997 - IPC

Abstract RU 2085329 C1

FIELD: metallurgy. SUBSTANCE: apparatus has pouring ladle joined with vacuumizer, which has cylindrical working cavity with throat and discharge pipe in its bottom. Discharge branch pipe is inserted into working cavity of intermediate ladle provided with pouring cups. Auxiliary branch pipe mounted in vacuumizer bottom is provided with supplying pipeline connected to branch pipe side wall. Space between branch pipe axes is 4-10 diameters of auxiliary branch pipe channel. Throat is formed as cylindrical channel with length equal to 0.2-0.6 of vacuumizer working cavity height and diameter equal to space between inner generatrices of branch pipes channels. Throat channel is positioned in symmetry between these generatrices. Conical lower part of vacuumizer working cavity has height equal to 0.15-0.3 of vacuumizer working cavity height. EFFECT: increased efficiency, simplified construction and improved quality of metal. 1 dwg, 1 tbl
