  • Control Of Metal Rolling (AREA)

Description

ратуры уменьшаютс  по экспоненциальному закону, поэтому приведенна  выше функциональна  зависимость достаточно точно описывает необходимую технологическую взаимосв зь между температурным полем раската и сопротивлением металла деформации, осуществл емую данным способом.The temperature is reduced exponentially, therefore, the above functional relationship rather accurately describes the necessary technological relationship between the temperature field of the roll and the resistance of the metal deformation carried out in this way.

Применение предлагаемого способа позволит повысить стабильность и точность прокатки , облегчит работу систем автоматического управлени  и регулировани  на стане.The application of the proposed method will improve the stability and accuracy of rolling, will facilitate the work of automatic control and regulation systems in the mill.
