    Abstract : In the steel industry, laser triangulation based measurement systems can be utilizedfor evaluating the flatness of the steel products. Shapeline is a company in Linköpingthat manufactures such measurement systems. READ MORE

  3. 7. The Process Influence on Strength Properties of an Austenitic Stainless Steel (254 SMO)

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Anna Hellqvist; [2014]
    Keywords : stainless steel; hot rolling; levelling; strength; material properties; process parameters;

    Abstract : This work has been performed at Outokumpu Stainless AB, QPE, in Degerfors where focus is on production of hot rolled tailor-made quarto plate in special stainless steel grades such as highly alloyed austenitics and duplex steel grades. After a period with low values in strength and a lot of deviations in tensile tests for the highly alloyed austenitic stainless steel, 254 SMO, there was a need to investigate what influence some parameters during process has on strength values.

  4. 8. Design and function of CVC rolls as a flatness actuator in a cold rolling mill

    University essay from KTH/Materialvetenskap

    Author : Jonas Johannesson; [2012]
    Keywords : Flatness; actuators; CVC; cluster mill; Cold rolling; strip; Planhet; ställdon; CVC; mångvalsarsverk; kallvalsning; band;

    Abstract : When cold rolling thin steel strips with high tensile strength, reversible cluster mills are used. The customer’s demands are high on the products flatness, which is controlled by the different flatness actuators that the mill is equipped with. READ MORE

    Keywords : cold rolling; material properties; heat treatment; production flow; machine tool; rolling tool;

    Abstract : This research is about a costly problem in the automotive industry due to tool fracture during the splines cold rolling of steel shafts. The objective is to study the cause of this failure and propose solutions that can be implemented in the workshop. READ MORE

  6. 10. Optimize cold sector material flow of a steel rolling mill

    University essay from KTH/Industriell produktion

    Author : Alvaro Baudet; [2010]
    Keywords : Value Stream Mapping; Discrete Event Simulation; Optimization; Storage Assignment Policy;

    Abstract : The steel production is a highly capital and energy intensive industry that due to recent raw materials’ price increase and lowered demand, it has been squeezed and forced to look more deeply on how to add value to the customer at lower operative costs. The project was carried out on site at the ArcelorMittal’s millin Esch-Belval, Luxembourg which comprises an integrated melt shop, continuous casting plant and the rolling mill with the objectives of proposing optimization rules for the cold sector of the rolling mill and to analyze the impact of the future truckbay shipment area.
