/D, numerical modelling of the process of plate rolling on the roughing mill was performed using the FORGE software program. The correct determination of the properties of steel in the form of stress–strain diagrams, allowing for the effect of band temperature and strain rate, enhances the accuracy of numerical computations, in which the finite

Mill automation, reheating furnaces, laminar cooling, empowering of mill drives by a 3rd main drive, coiler, etc, were the significant milestones in this long mill life time. Strips of 1.9 – 14.0 mm thickness and 900 – 1550 mm width are produced. Acesita's mill produces mainly stainless strip, silicon grades but also carbon strip.

Today, thanks to Danieli "Micromill" - a Minimill based on ultra-compact design and extremely low transformation costs - it is possible to produce 250-300,000 tpy of long products with an overall investment per ton typical of a 1.0-1.5 Mtpy Minimill. The relatively low output will assure additional savings in transportation costs, as these ...
