Název v původním jazyce

Physical modelling of the seamless micro-alloyed steel tubes production depending on the different temperatures and rpm speeds of the working rolls

Popis výsledku v původním jazyce

The paper presents laboratory physical modeling of the seamless tubes production, specifically the first step of the Mannesmann production process, the so-called punching. A “Universal rolling mill” at MATERIAL & METALLURGICAL RESEARCH Ltd. was used for experiments. The experimental material was micro-alloyed steel. The tests were carried out at four different heating temperatures and at different rpm speeds of the working rolls. The other settings of the rolling mill remained the same. In terms of the geometrical parameters, the biggest necking of the punched sample (preferably at both ends) was observed with increasing temperature and strain rate. The torque decreased with increasing temperature and with lower roller speeds. The punching time and the total current power consumption decreased with increasing temperature and with a higher deformation rate.
