The Numerical And Optimal Design Of The H-type Tundish

This topic is the design of the H-type tundish An gang the middle of the two streamsbased on package size. The purpose of this research is to get a better structure of thetundish, Tundish to purify and improve the temperature distribution of molten steel.Movement and flow field of molten steel within the tundish mainly through thecombination of the hydrodynamic model and the mathematical simulation model tosimulate and study inclusion removal in order to achieve the best effect. Firstly, on thebasis of the similarity principle, the establishment of tundish water model of continuouscasting and rolling process, orthogonal experiment method to design a pilot program of25(five-level, four factors), the bag retaining wall location and height package Steel Flowand Temperature Field in the impact to determine the optimum program of three kinds ofthe retaining wall installations. Three kinds of the better programs in the water modelresults and is not applied when the retaining wall of the tundish use CFD software fluentfor the computer simulation, the simulation of liquid steel in the tundish flow field, andthen by comparing the final optimal solution17the average residence time to675.00s, thedead zone was7.41%. Beside the results of the study show that: in the position of theretaining wall up and down on the height of the retaining wall and fixed, the height is300mm retaining wall, the steel flow a good condition, be helpful for inclusion removed. Upand down in the position of the retaining wall and the height of the retaining wall fixed,when the height is350mm retaining wall, the steel flow a good condition, be helpful forinclusion removed. In the height of the retaining wall up and down on the position of theretaining wall and fixed, when the relative distance of the retaining wall and700mm, thesteel flow a good condition, be helpful for inclusion removed.
