Abstract
PURPOSE: To rapidly stop the effluent of the slag at the end stage of the tapping work for the molten steel, by supporting the sprue stopping plug of the converter using the support bracket, and by inserting the plug into the molten steel in the converter, and by bringing down the plug using the hydraulic cylinder.
CONSTITUTION: In case of tapping the molten steel out of the tapping hole 39 of the converter 11, the effluent of the slag at the end stage of effluent of molten steel is to be rapidly stopped; for this purpose, the plug is used for stopping the tapping hole 39 without setting up the converter. Hereupon, the turning arm 8 is horizontally freely rotatably attached to the upper and lower parts 4 installed in the staionary frame 1 so as to be freely elevating. The saddle 13 is attached to the turning arm 8 so as to be freely movable in the direction of length of the turning arm 8, and also, the support arm 16 is vertically freely rotatably attached to the saddle 13; in which, the tip of the support arm 16 is provided with the support bracket 42 for vertically freely movably supporting the support rod 41 for supporting the stopping plug for the tapping hole 39 of the converter 11. When the slag begins to flow out of the tapping hole 39, the support arm 16 is instantaneously turned downward by the hydraulic cylinder 18, and the plug rapidly closes the tapping hole 39.
