Impact of temperature and working roll rotational speed on the qualitative propeerties of seamless N80 steel tubes in pilot-scale production

Popis výsledku v původním jazyce

The formability of seamless tube production, specifically the initial step of the Mannesmann process—referred to as punching—was investigated through laboratory physical modeling using a "Universal Rolling Mill" at MATERIAL & METALLURGICAL RESEARCH Ltd. The material studied was a medium-carbon V-Ti-N microalloyed N80 steel. The experiments were conducted at four different heating temperatures and at varying rotational speeds (rpm) of the working rolls, with all other rolling mill parameters kept constant. In terms of deformation parameters, the most pronounced necking of the punched sample, particularly at both ends, was observed with an increase in temperature and strain rate. The applied torque exhibited a decrease with rising temperature and lower working roll speeds. Additionally, both the punching duration and total electrical power consumption showed a reduction as temperature increased and deformation rate was elevated.
