“…That's why before TO modes of mathematical modeling in program ANSYS were calculated temperature and stress conditions, hot rolling rolls made of steel 70Cr3Mn2WoTiNb with the diameter of 600 mm. The analysis showed that in the process of heat treatment there is a equilibrium distribution of temperature fields over the cross section of a large-sized tool, a low level of residual stresses is also formed both at the stage of preliminary and final heat treatment [7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

The scientific bases for the development of rational compositions and methods for hardening a large-sized metallurgical tool from micro-alloyed steels are stated. Based on the generalization of the experimental data, the regularities of phase and structural transformations at various stages of the technological cycle are revealed; the relationships between structural parameters, chemical composition and mechanical properties have been studied and described.
