Abstract
The utility model relates to a tundish cover formed by a cover plate. The cover plate includes a main support, an auxiliary support, a steel screen, anchoring members and a refractory material casting layer. The main support is a rectangular steel structure frame, and the auxiliary support is a steel structure frame shaped like a Chinese character jing (meaning well in English) and is fixedly connected inside the main support. The steel screen is fixed under the auxiliary support. The multiple anchoring members are fixedly disposed on the inner side of the frame of the main support and on the steel screen. The refractory material casting layer wraps the inner side of the main support, the auxiliary support, the steel screen and the anchoring members. The refractory material casting layer is equipped with multiple through holes that penetrate from top to bottom. No metal pieces are arranged on the upper and lower surfaces of the cover, so that metal oxidation, ablation, deformation or the like are not liable to occur. No steel plates are employed to restrict the upper and lower surfaces of the cover and the periphery of the cover. The refractory material casting layer is not liable to crack and spall, so the high temperature performance is stable and the service life is prolonged. The tundish cover having a simple structure needs the less amount of metal and is low in manufacture cost.
