In this paper, properties of slab deformation in sizing press mill as one of the slab reduction processes in hot rolling mills have been evaluated using the elastoviscoplastic finite element method with explicit formulation. Effect of prarameters such as initial slab width and thickness, reduction, feed pitch, and anvil speed on factors such as dogbone formation, head and tail fishtail profile,...

A systematic study is conducted on a 17% Cr dual stabilized ferritic stainless steel (FSS) to the evolution of texture during hot rolling and its effect ridging resistance after cold annealing. Hot 4-high laboratory mill with finishing temperatures in range 1000–810 °C cover microtexture under both conventional conditions when using low temperatures. Subsequently, hot-rolled coils are rolled an...

The mechanical rolling conditions in hot strip mills are precisely defined by various variables, which are taken directly froth the rolling schedule (separation force, torque. speed. strip thickness) or calculated from figures of the rolling schedule and dimensions of the mill (strip reduction, roll diameter etc.). These variables allow to describe the mechanical rolling conditions of all passe...

There is an Iurgent need for automatic systems for quality control of flat steel products to meet the ever increasing demand from customers, and for process control to prevent damage to production. To achieve these goals, those inspection systems should detect and recognize defects using image processing and pattern recognition methods. Such complex systems are difficult to compare and the spec...

Raftery, Kárnỳ, and Ettler (2010) introduce an estimation technique called Dynamic Model Averaging (DMA). In their application, DMA is used to the problem of predicting the output strip thickness for a cold rolling mill, where the output is measured with a time delay. Recently, DMA has also shown to be very useful in macroeconomic and financial applications. In this paper, we present the eDMA p...

Thickness accuracy of plate production depends on Automatic Gauge Control (AGC) in the plate mill area. A typical modern thickness control system design and implementation of a steel plate mill is discussed together with the impact on the design of process models, available measurements, available control actuators and material properties. A highlevel software design approach provides the abili...

The paper refers to an intermediate stage of the running international project ProDaCTool which aims to develop the decision-support tool for operators of complex industrial processes. It should help to guarantee stable highest quality of product by optimal settings of machinery. The main idea of the project is to extract valuable information from a huge amounts of process data and to store it ...

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...
