Abstract

The invention relates to a composite frame cladding cover for long-life tundish. The composite frame cladding cover comprises a composite frame structure, a refractory material and triangular anchoring parts, wherein the composite frame structure comprises an outer beam, rectangular frames and rib plates, the rectangular frames are welded and connected by transverse side plates and longitudinal side plates, the rib plates are arranged in the rectangular frames, the rib plates are connected by transverse rid plates and longitudinal rid plates, the triangular anchoring parts are uniformly fixedto the rectangular frames and the rib plates, the composite frame structure and the refractory material are integrally poured and formed, a large steel flowing hole, two baking holes, a small steel flowing hole, two small exhaust holes and a temperature measurement hole are formed in a steel structure poured by the refractory material, the shape of the composite frame structure is consistent withthat of the opening of the tundish, and the thickness of the rectangular frames of the composite frame structure is consistent with that of the cladding cover of the tundish. The cladding cover for the tundish has the advantage of long service life, thereby reducing the enterprise cost.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to a composite frame structure cover for a long-life tundish. Background technique [0002] The tundish is one of the containers used in the metallurgical continuous casting process. The tundish mainly plays the role of decompression, steady flow, removal of impurities and diversion of molten steel. Its thermal state during production and turnover directly affects the change of molten steel temperature. In order to reduce the excessive cooling of molten steel, it is generally implemented by strengthening the tundish baking, improving the heat turnover of the tundish, optimizing the structure of the tundish lining, adding heat insulating agent during the operation of the molten steel, and covering the upper surface of the tundish. Among them, the use of tundish cover is a relatively simple and direct method. [0003] The tundish cover is the cover covering the tundis...
