Abstract
A mathematical model for finding the nature of the liquid metal motion in the section mold and its speed near the solidifying crust was made on the basis of the theory of free and limited submerged jet. The authors have selected the mathematical model to determine the heat fl ux when moving superheated liquid steel at a predetermined speed along the two-phase boundary. Therefore, the mathematical model was proposed to find the changes in the thickness of the ingot crust along the height of profiled square mold on diff erent surfaces and in its output around its perimeter with a horizontal displacement of the axis of the jet of the metal fed into the mold. Computer modeling of the asymmetry of crust growth along the perimeter and the height of the shell of the section mold with square section of 150×150 was made at the displacement of axis of the open metal jet. It was established that the horizontal displacement of the axis of the metal open jet of 40 mm may lead to a local change in thickness of the crust at the outlet of the mold on the left side up to 2 mm.
