Computer modeling of a combined process of continuous casting with electroslag heating of a rail steel was carried out. The program THERCAST® was applied, which allows accounting for the peculiarities of design of a definite continuous casting machine. Using calculations, the initial parameters of not only of casting speed, but also of secondary cooling and their effect on depth of molten pool of a continuously-cast ingot were established. The peculiarities of matching the billets of separate passes at different speed of the ingot withdrawal were also studied. 10 Ref., 1 Table, 4 Fig.

Key words: continuous casting; ESR; secondary cooling; centerline segregation; hypereutectoid railroad steel
