    摘要: A molten metal pouring nozzle for a continuous casting machine having an endless-travelling type mold, wherein the endless-travelling type mold is formed with two pairs of opposing wall members endlessly travelling in the same direction and at the same speed, and one end of the pouring nozzle is connected to a tundish for receiving molten metal, and the other end of the pouring nozzle is inserted into the mold. The molten metal pouring nozzle of the present invention comprises a nozzle body made of a refractory and a flow regulator made of a refractory. The nozzle body (14, 20) has a bore (1a, 3a), through which molten metal flows, along the axial line thereof, and the sectional area of the downstream end portion of the bore (1a, 3a) becomes gradually larger toward the downstream end thereof. The flow regulator (15, 18) is arranged at the center of the downstream end portion of the bore (1a, 3a) of the nozzle body (14, 20). The flow regulator (15, 18) forms, in cooperation with the bore (1a, 3a), a path for molten metal, by which molten metal flowing through the bore (1a, 3a) impinges against the inner surface of the mold, near the downstream end of the nozzle body (14, 20).

    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: 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.
