Tundish with electromagnetic heating water gaps

Abstract

The invention discloses a tundish with electromagnetic heating water gaps. Special electromagnetic heating water gaps are arranged on the bottom of the tundish body, so as to form the tundish capable of adjusting and controlling stream temperature of the water gap. One or more electromagnetic heating water gaps can be mounted on the bottom of the tundish according to the need, so as to form a tundish capable of controlling stream temperature of each water gap independently. The tundish is high in heating efficiency and capable of adjusting and controlling temperature of each pouring stream temperature independently, so that purposes of realizing optimum pouring temperature, avoiding block of water gaps, reaching low-superheat degree pouring and increasing quality of casting blanks are achieved; the tundish can be widely applied to metallurgy continuous casting production, particularly to production of multi-stream, multi-stream and large-section, and oversized-section continuously cast blooms; the tundish is accurate in temperature control, high in controllability, low in operation cost, and capable of increasing quality of products remarkably and reducing production cost.

Description

technical field [0001] The invention relates to a tundish for multi-strand continuous casting production in the field of iron and steel metallurgy, in particular to a tundish with an electromagnetic heating nozzle, which has the functions of heat preservation, heating, freezing of the waterproof port of the tundish, and realization of low superheat casting Tundish. Background technique [0002] With the continuous improvement of steel quality due to social demand, continuous casting tundish, as an indispensable link between steelmaking intermittent tapping and continuous casting continuous casting, has attracted more and more people's attention. The research on the flow field and temperature field found that with the continuous expansion of the section of the continuous casting slab, the continuous increase of the number of continuous casting strands, the increase of the size of the tundish, the greater the difference in the uniformity of the temperature in the tundish, the ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a tundish with an electromagnetic heating nozzle to overcome the shortcomings of traditional tundishes such as low heating efficiency, poor ability to independently control the temperature of each casting stream, and unfavorable overall reduction of molten steel superheat; solve the problem of opening a new tundish The nozzle is easy to freeze at the initial stage and the superheat was controlled too high to avoid freezing in the past.
