12%Tests were performed on the continuous 250-2 light-section mill at the EVRAZ ZSMK combine to study the effect of the deformation regimes on the healability of surface defects on semifinished products. It was confirmed experimentally that increasing the degree of similarity between the pass and the cross-sectional shape of the initial semifinished product increases the …

Some aspects on lubrication and roll wear in rolling mills

rolling speed, rolling time) and tribological factors (friction, wear, lubricant) [1]. In the first part of the thesis it is shown that biodegradable synthetic water-based lubricants, which are less detrimental to the environment, may substitute conventional mineral oils and oil-in-water emulsions in cold rolling. This is also clear from [2-4].
