Abstract

In this paper, hotrolling tests oflow-carbonsteel were carried out on a 2-high Hille 100 experimental rolling mill at various speeds and reductions. The rollingtemperatures were between 1000 and 1030 °C. Nitrogen protection was used to control the scale thickness when the test samples were heated in the furnace and cooled in a cooling box. The rolling forces, rolling torques and scale thicknesses before and after rolling were measured. Surface characteristicsof the steel samples were analyzed with SEM and Atomic Force Microscope (AFM). X-ray diffraction was performed to characterize the phase composition of the scale layers. The effects ofscale thickness on rolling force and torque were also investigated.
