NOSE RING FOR METALLURGICAL PROCESSING VESSELS

摘要

A ring structure for cooling the nose or mouth portion of a metallurgical processing vessel, such as a basic oxygen furnace. The ring is formed of radially outwardly extending upper and lower plate members secured to the shell of the vessel at the mouth or nose portion thereof. An outer face plate is fixed at its axial ends to the upper and lower plates and is spaced from the vessel whereby a continuous coolant receiving cavity is defined. Coolant inlet and outlet openings communicating with the cavity are provided. Baffle plates are disposed throughout the coolant cavity for assuring turbulent flow of coolant through the ring to thereby improve heat transfer between the shell and the coolant. An outlet chamber is arranged in communication with the coolant outlet with a portion of the chamber being above the plane of the cavity for assuring complete filling of the cavity with coolant and thereby eliminating the possibility of formation of gas pockets in the ring.
