Numerical Analysis of Liquid Steel Flow Structure in the One Strand Slab Tundish with Subflux Turbulence Controller and Dam

Abstract: The paper present the results of computational calculation showing liquid steel flow in the tundish. The one-strand slab tundish is used to casting slabs. The internal work space of tundish was modified by two flow control devices (FCDs). The first device is subflux turbulence controller situated in the pouring tundish zone. The second FCD is a dam with two holes. The dam presently using in the industrial conditions was modified by changing a height. Adapted to internal work space new flow control devices were… Show more

“…Advanced computer programs are used for numerical modelling of the continuous steel casting process, and both proprietary and commercial simulation programs are used for this purpose. [2][3][4][15][16][17][18] Assuming that a numerical model of the steel continuous casting process is used for this purpose, one should note that the model form strongly depends on the problem that we want to solve with this model. In the ProCAST package, the metallurgical length of the strand and the shell thickness under the mould may be calculated with the thermal or thermal + flow models.…”

“…The development of the steel continuous casting primarily serves the improvement of the production process by improving the quality of the steel products. [1][2][3][4][5][6][7][8][9][10][11] The cooling water flow rate in individual cooling zones of the continuous casting machine, which is correlated with the cast strand casting speed, is one of the most important process parameters. Due to the need to cast new steel grades, it is necessary to develop a strategy for the selection of cooling parameters.…”

“…The calculations of model flow velocity scales and flow time (S Q i S t ) were made by assuming that in a real conditions cross-section of the cast ingot is 140 x 140 mm, with the casting speed v odl = 2 m·min −1 = 0,03 m·s −1 . Physical model of steel CC device is designed for visualization character test and thanks to the installed measuring apparatus it enables the determination of residence curves -RTD [9][10][11][12].…”

“…These operations are for example the temperature control of alloy and chemical composition, the melt flow control to enable the non-metallic inclusion separation and transport them to the slag layer. Flow behaviour in the tundish is governed mainly by the size and shape of the tundish and the location of flow control devices, such as dams, weirs, filters, pour pad, baffles with holes and turbulence inhibitors [3,4]. These devices are designed to allow the implementation of the main objective of the flow in the tundish which is to ensure uniformity and inclusion removal, while avoiding flow-related problems.…”
