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...
متن کاملCoiler Control in Endless Hot Strip Rolling
JFE Steel Corporation’s East Japan Works (Chiba District) started operation of No.3 Hot Strip Mill in 1995. This line was the first in the world to achieve “endless hot strip rolling.” A new Coiler Control technology was developed. Copyright 2005 IFAC
متن کاملOptimum Work Roll Profile Selection in the Hot Rolling of Wide Steel Strip Using Computational Intelligence
The finishing train of a hot strip mill has been modelled by using a constant volume element model. The accuracy of the model has been increased by using an Artificial Neural Network (ANN). A non-linear Rank Based Genetic Algorithm has been developed for the optimization of the work roll profiles in the finishing stands of the simulated hot strip mill. It has been compared with eight other expe...
متن کاملPrediction of Work-Piece Constitutive Equation in Hot Rolling of Strip
Dimensional control of the work-piece in steel industry is of important interest. The main aspects in overcoming the thickness control are variations in material strength due to variations in chemical composition, work-piece temperature, reduction and the strain rate applied to the work-piece. In this paper based on the main parameters affecting the rolling force an attempt been made to give a ...
متن کاملPrediction of Work Roll Initial Crown according to Desired Strip Profile in Hot Rolling
The final hot strip profile is a superposition of the roll initial crown, the roll bending and flattening crown, the roll wearing crown and the roll thermal crown. In this research, linear regression models are proposed to predict the roll force, the roll wearing crown and the roll thermal crown using experimental data provided by Mobarake Steel Complex (MSC). The short beam theory based on ela...
