Evaluation of Deformation Behavior of Oxide Scale in Hot Rolling Process by Vacuum Hot Rolling Mill

Metallurgically Consistent Determination of Steel Hot Strength Using Process Data from Hot Strip Mill Rolling

It is not rare to observe an inverse relationship between hot strength determined from rolling load of the finishing stands of the hot strip mill and strain. This situation was already described in the literature and is explained by the use of inverse rolling load models that assumes sticking friction in the determination of hot strength. The aim of this work was to show that this “work softeni...

Magnificent Grain Refinement of Al-Mg2Si Composite by Hot Rolling

The effect of chemical composition and the hot rolling operations on the microstructure and mechanical properties of in situ aluminum matrix composite with Mg2Si phase as the reinforcement was studied. It was revealed that the modification by phosphorous results in the rounder (more spherical) primary and secondary (eutectic) magnesium silicide intermetallics. During hot rolling, the primary pa...

Significance of Heat Conduction Parameter along the Rolling Direction in the Thermal Modeling of the Hot Rolling Process

Obtaining temperature distribution data of slabs under rolling is essential as the mechanical and metallurgical properties of the metal under this process vary with temperature. Using the control volume method, a mathematical model is employed in this study to predict slab temperature in the hot roll process at Mobarakeh Steel Company. The effects of different parameters including the heat resu...

Multivariable controller design for a hot rolling mill

Simulation System of Multistage Hot Rolling Process of Flat Products

The properties of each deformed product are decisively influenced by production process. By means of directed control of the various steps of process it is possible to obtain the desired properties. In order to reach this purpose and to estimate the properties of the end product the whole process chain must be presented as the whole set. This integrated approach starts with the solidified melt ...
