SUBMERGED BRANCH PIPE FOR VACUUMISER Russian patent published in 2015 - IPC C21C7/10

Abstract RU 2557046 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgical equipment and can be used at the metallurgical enterprises during tapped-metal degassing. The submerged branch pipe contains metal structure lined by refractory rings and refractory concrete. The bottom refinery ring is made with l-shape, and branch pipe is equipped with support metal ring secured under the specified bottom refractory ring, and between internal surface of the metal structure and external surface of the refractory rings including the specified bottom refinery ring a buffer layer compensating the thermal expansion is located.

EFFECT: invention ensures significant rise of the refractory resistance of the entire structure, and increases durability of the designed submerged branch pipe.
