ABSTRACT:
A rotary slide closure for a vessel provided with a fire-proof lining includes a closure block contacting a beveled seat of a seat block and being rotatably mounted relative to the seat block. The closure block and the seat block each have at least one flow-through opening which can be brought into register by turning of the closure block so as to form a pouring channel extending from the center of the closure block. The surface of the seat block forming the beveled seat, faces the interior of the vessel and the closure block contacts the surface forming the bevel seat from the interior of the vessel.
