Title:
ROTARY SLIDING CLOSING DEVICE FOR MOLTEN METAL VESSEL
Document Type and Number:
Japanese Patent JPS5816769
Kind Code:
A
Abstract:
A rotary sliding closure unit includes a stationary support frame adapted to be mounted removably adjacent to pouring opening of a liquid melt container. A stationary refractory plate has therethrough a flow passage and has an annular, ring-shaped configuration. The stationary refractory plate is supported by the stationary support frame such that the flow passage is in communication with the pouring opening. A rotary refractory plate is positioned in sliding abutting contact with the stationary refractory plate, has therethrough a plurality of flow passages to be moved selectively into and out of alignment with the flow passage of the stationary refractory plate, and has an annular, ring-shaped configuration. A rotary support frame supports the rotary refractory plate against the stationary refractory plate for rotational movement with respect thereto. The stationary and rotary refractory plates have complementary, annular, abutting relative sliding surfaces. The stationary and rotary support frames are disc-shaped members. Structure is provided to coaxially align the stationary and rotary support frames, and the stationary and rotary refractory plates and to urge the rotary refractory plate toward the stationary refractory plate.
