Abstract: An exchangeable valve plate assembly is provided for use in a slide gate valve. The exchangeable valve plate assembly includes a refractory exchangeable plate that may be replaced in the assembly without removing the slide gate valve from service. The exchangeable plate includes a concave cylindrical load surface(s) that is configured to be engaged by a cylindrical bar tip of a rocker arm to distribute load across a plate sealing surface and maintain a more constant load condition as the height of the plate stack changes. The rocker arms that load the plate also has the ability to float in its lateral relationship to the a pouring orifice centerline so as to further minimize changes in load force distribution to the exchangeable plate as the thickness of the plate stack changes.

Abstract: With a rotary nozzle of the type in which a slide plate brick having at least one nozzle bore is rotated so as to adjust the degree of overlapping between the nozzle bore thereof and a nozzle bore of a fixed plate brick to control the rate of pouring of molten steel or the like, the bricks constituting the fixed plate brick and the slide plate brick are formed into the most rational and economical shape for the purpose of seeking a reduction in their cost and also the bricks are used for the purpose of seeking a reduction in the running cost of the rotary nozzle. To achieve these purposes, the shape of the brick 40 is formed into a substantially elliptic shape and nozzle bores 41a and 41b are provided in the respective eccentric positions.

Abstract: A slide gate valve having a cementless joint between the valve and a metallurgical vessel containing molten metal is provided for facilitating the replacement of worn refractory components in the valve. The slide gate valve generally comprises a fixed refractory plate having a flow opening disposed generally in alignment with a tap opening of the metallurgical vessel, a movable refractory plate having at least one flow opening, an air cylinder for reciprocally moving the movable plate with respect to the fixed plate to control the overlap of the flow openings in order to modulate a flow of molten metal through the valve, a spring assembly for pressing the movable plate against the fixed plate to provide both static and dynamic seals between the plate, and a cementless joint between the flow tap of the metallurgical vessel and the fixed refractory plate formed by joint surfaces on the flow tap and the fixed plate which are compressively engageable to form a molten metal tight joint therebetween and compression means, which may be a spring arrangement, for sealingly compressing the mutually-engageable joint surfaces to create a joint without the need for extraneous adhesives or cement. In the method of the invention, the compression means of the joint preferably acts on the fixed plate when the plate is laterally slid away from the flow tap incident to a replacement operation to wipingly clean the joint surface of the flow tap of the metallurgical vessel.
