Flow of molten metal to the mold of continuous casting machine (CCM) is an insufficiently studied process up to the present day. This paper is a continuation of author’s works published in scien tific se rials last years. It shows the possibility of a theoretical research of motion kinetics and thermal flows of molten metal in the mold during traditional casting by using hydrodynamic theory and mathematical physics equations and a proven numerical approach. This familiar calculation methodology makes it possible to calculate flows of molten metal motions and their temperatures in the mold and to compare the obtained results with ones obtained during usage of other methods of metal pouring including proposed method. This paper describes and solves three-dimensional problem of determination of velocity and temperature fields in metal poured to CCM mold from the submerged nozzle to the round deflector. In addition, the calculation methodo logy described in previous works of the authors is used, namely, the constitutive equation system, numeric method, numerical scheme and algorithm for solving the problem. Hardened metal crust forming on the mold faces was not considered in this calculation. For the results objective analysis of the problem solving in two ways (traditional and proposed), the same theoretical (speed of pulling-out from crystallizer) and geometrical parameters of rectangular cross-section mold were taken. Application for an invention for the described alternative method of liquid metal supplying to rectangular mold was registered (No. 2018108974/02 (013808)). The article contains some results of numerical solution of the problem in particular schemes of molten metal flows and their temperatures over different sections of the mold.
