APPARATUS FOR FLOW-LINE VACUUM PROCESSING OF CONTINUOUSLY CAST METAL Russian patent published in 1995 - IPC

Abstract RU 2037371 C1

FIELD: vacuum processing of metal in the process of continuous casting. SUBSTANCE: apparatus has pouring ladle with pouring cup disposed in ladle bottom, evacuator with branch pipe mounted in its bottom and extending into intermediate ladle and vacuum line communicated with vacuum pump. Branch pipe is made in the form of two concentric refractory tubes positioned in spaced relation one within the other and interconnected through longitudinal webs disposed in space between tubes. Inner tube has length exceeding that of outer tube and is positioned so that its ends extend beyond ends of outer tube. Outer tube is provided with supply pipeline. EFFECT: increased capacity, simplified construction and enhanced reliability in operation. 2 dwg
