Экспериментальные исследования комплексного влияния температурных и деформационных параметров прокатки на энергосиловые параметры процесса

Abstract

In the research an experimental investigation of complex influence temperature of beginning of rolling and difference deformation mode on сhanging power and torque of rolling for the conditions of hot rolling steel square specimens with low temperature heating of steel Fe360B on smooth rolls. Specimens dimensions 25 × 25 × 200 mm. rolls diameter 205 mm, length 400 mm.. Deformation of specimens performed in 4 passes, according to various modes of deformation. Realization of a modes was carried out in 2 and 3 pass. Measurement results force of rolling showed that the lowest levels of rolling force inherent for regressive mode deformation. When using the an increasing modes of deformation may reduce the temperature of the heating of the rolling up to 1100 ° C without a significant increase in energy and power parameters of rolling. For all the deformation modes of the rolling most forces are manifested most in passages with maximum reduction per pass. The data on the temperature distribution of specimen, power and torque of rolling along the aisles. Presented in the paper data can be used to calculate power parameters in the design or improvement of rolling mill stands.
