Effect Of Steel Flow Control Devices On Flow And Temperature Field In The Tundish Of Continuous Casting Machine

Abstract: The mathematical model and numerical simulations of the liquid steel flow in a tundish are presented in this paper. The problem was treated as a complex and solved by the finite element method. One takes into consideration in the mathematical model the changes of thermophysical parameters depending on the temperature. The single-strand tundish is used to casting slabs. The internal work space of the tundish was modified by flow control devices. The first device was a pour pad situated in the pouring tundish zo… Show more

“…Variables with temperature thermo-physical properties and properties such as: laser beam power Q = 3.2 kW, welding speed v = 1.0 m/min, the beam radius r 0 = 1 mm, depth penetration s = 7 mm were used in numerical calculations. The analysis of thermal phenomena is made on the basis of the numerical solution of energy conservation equation together with Fourier law [12][13][14][15] using finite element method (FEM). The temperature field expressed in the criterion of weighted residuals method is described by the following equation:…”

“…For example the mathematical description of the considered phenomenon is required in the numerical analysis of the solidification in the mold [4,5]. Currently many advanced numerical methods such as the FEM are used to model complex mechanical phenomena [6][7][8][9]. Numerical investigations based on the FEM in the case of air gap formation process during solidification of pure metal was discussed in [10].…”

“…The heat flow at the interface between the two bonded elements is described by the Fourier law taking account of the contact resistance r s . Applying the fourth type of boundary condition causes continuity of temperature distribution and heat flux [16]. The scheme of the considered system is shown in Figure 2.…”
