摘要： A rotary nozzle in which at least one coil spring is removed, acting to increase the clearance between a surface of the bottom plate brick and a surface of the slide plate brick. This mechanism is capable of improving the pushing force in the vicinity of the nozzle hole, and prevents molten steel leakage, thus prolonging the life of expensive bricks.

摘要： A door opening/closing device of door-type rotary nozzle which cannot fit collector nozzle (16) unless clampers are removed. There is no possibility of pouring molten metal while forgetting to remove the clampers (25). When the fixed frame (7) is opened or closed, a ladle is fitted by a 90 degree angle with its bottom almost vertical. So, the fitting and removing operations of the clampers (25) can be performed in front of an operator, which makes the operation very easy.

摘要： A fixed plate (15) is provided in a fixed metal frame (14). An opening and closing metal frame (17) having a movable plate (21) is attached to the fixed metal frame (14) so as to be openable and closable. The fixed metal frame (14) is provided with a pressurizing mechanism (23) applying a pressure in a closing direction generated by a spring (25) to the opening and closing metal frame (17) in a closed state. An actuating member (29) is movably provided at a position facing the pressurizing mechanism (23). Cam surfaces (30d, 32a) are provided between the actuating member (29) and the pressurizing mechanism (23). The spring (25) is deformed against an urging force thereof on the basis of operations of the cam surfaces (30d, 32a) in accordance with a movement of the actuating member (29), and the pressure applied to the opening and closing metal frame (17) is strengthened.

摘要： A rotary nozzle which is simple in construction and easy to manufacture its bricks, has no danger of leakage of molten steel and is capable of rotatably connecting a collector nozzle and a long nozzle. The rotary nozzle includes a fixed plate brick attached to a base member and having at least a sliding surface thereof formed to incline with an angle of .theta..degree., a slide plate surface having at least a sliding surface thereof formed as an inclined surface corresponding to the sliding surface of the fixed plate brick and fixedly mounted, along with a collector nozzle, in a supporting member, and a frame vertically displaceably supporting the supporting member through a plurality of spring means and bolts and adapted to be driven by driving means mounted on the base member. The lower end of the collector nozzle is formed into a spherical shape so as to ensure its smooth connection with a long nozzle and its rotation.

摘要： In a rotary nozzle brick body formed into a substantially egg-like shape in it's plan view, the present invention secures a contact area of a nozzle portion and improves a configuration factor which considerably affecting the durability of the body. A rotary nozzle brick body is characterized in that the external shape in plan view is comprised of first circular portions (G), second circular portions (H), third circular portions (K), and tangent lines connecting the first circular portions and third circular portions so that a substantially elliptical shape is formed by increasing the circular portion and shortening the tangent lines, instead of a substantially egg-like shape having long tangent lines. Since the substantially elliptical shape is formed by reducing the linear portion of the brick body in it's plan view while the shape is expanded circularly, the contact area is maintained even if the sliding plate brick is rotated up to it's full-opened state, thereby eliminating a fear that molten steel or the like may leak.
