- Abstract
The article presents data on mathematical and physical modeling of two-stage cooling of large size (diameter 16 mm) rolled in coils in Stelmor line flow. The software DEFORM 3D + HEET THEATMENT as well as the scientific complex for physical modeling of various technological processes GLEEBLE 3500 are used. The effective temperature of austenite (approximately 980°C) and the rate of air cooling (31°C/s) of rolled in coils are determined in the course of the investigation. They provide to obtain the best set of structural components. Thus, the number of fine pearlite at a single point obtained in accordance with GOST 8233 amounts to 70% - 80% of the surface and to 60% -70% of the cross section. The uniform distribution of perlite single point refers to the grid of ferrite and/or cementite in absence of any hardening structures are absent along the entire cross section. This results in a metal, which can be drawn with no use of additional heat treatment of patenting.
