Long-service-life balanced tundish

Abstract

The invention discloses a long-service-life balanced tundish which comprises a tundish main body. The tundish main body comprises a permanent layer, a work layer is arranged on the inner side of the permanent layer, work layer parts located on the tundish bottom, tundish wall and slag line portions are formed by laying different dry materials, and a plurality of brick cups are evenly arranged in the middle of a cavity of the work layer, the inlet end of the tundish main body is provided with an integral current stabilizer, the permanent layer of the tundish main body is fixedly provided with an impact plate located below the integral current stabilizer, the lower portion of the tundish main body is provided with a sliding block, and a water feeding port is fixedly arranged in the sliding block. Erosion of molten steel on the work layer, particularly scouring erosion to the work layer part near the impact area can be reduced, a combined sliding block zirconium core is adopted, the waterfeeding port is in close fit with the sliding block, steel clamping at the contact face position of the sliding block and the water feeding port is avoided, the service life of the water feeding portis prolonged, and therefore the purpose of effectively prolonging the continuous using time of the tundish is achieved.

Description

technical field [0001] The invention relates to the technical field of continuous casting, in particular to a tundish with long service life and balanced performance. Background technique [0002] Steel material is a very important basic raw material, which plays an indispensable role in infrastructure construction, machinery production, national defense construction and other fields. At present, in order to improve production efficiency, modern steel production enterprises usually adopt continuous casting technology. Compared with traditional die casting, continuous casting has the advantages of increasing metal yield and reducing energy consumption, and can reduce metal resources and energy consumption. The steelmaking production process can be simplified, the process can be shortened, and the production efficiency can be improved. The tundish is one of the core equipment in the short-process steelmaking and continuous casting production process. Its function is to accom...

AI Technical Summary

Problems solved by technology

[0003] The erosion of molten steel on the working layer of the tundish, especially the high temperature and high frequency of molten steel erosion on the working layer near the impact zone, and the loss of blocks of the nozzle under long-term high-temperature work, limit the continuous use of the tundish. time

Frequent replacement of tundish will disrupt the production rhythm to a certain extent, increase production cost and reduce work efficiency
