ROTARY CERAMIC VALVE Russian patent published in 2023 - IPC B22D41/26 

FIELD: metallurgy.

SUBSTANCE: rotary ceramic valve contains a body (1) with a receiving hole in the side surface of the upper part and a rotary plug (2) placed in it with a metal outlet channel having inlet and outlet holes. The plug (2) is made with an upper conical (3), lower cylindrical (4) and supporting (5) parts. The body is installed in the boom (6) of the bottom of the metallurgical container with the upper part protruding above the surface of the bottom lining. The body is connected to the external clamping flange (7) and together with it is pressed to the bottom by clamping wedges (10) on the mounting axes 11. The supporting part (5) of the plug is spring-loaded by an elastic element (12) through an internal pressure flange (13) fixed to the body and an external pressure flange (7). When releasing the metal, the turning device (17) acts on the plug (2) to rotate it relative to the body (1) and align the inlet hole on the side wall of the upper conical part (3) of the plug with the receiving hole in the upper part of the body. The flow rate of the produced metal is controlled by partially blocking the indicated holes.

EFFECT: discrete release of metal from the metallurgical container is ensured by eliminating the solidification of the metal in the metal outlet channel of the valve.
