  1. 11. Potential methods of measuring the stirring intensity during secondary steel making in the ladle furnace

    University essay from KTH/Materialvetenskap

    Author : Karin Törner; Sofie Nabseth; [2016]
    Keywords : ;

    Abstract : The main objectives of this research were to find a measuring technique for the gas stirring intensity and relate this to the argon gas stirring in the ladle furnace. However, the investigation mainly focused on methods of measuring the true amount of argon gas entering the ladle furnace, since this was needed to further determine the gas stirring intensity.

  3. 12. Equipment for bearing housing change of work rolls in a steckel mill

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Joakim Norman; [2015]
    Keywords : Steckel mill; bearing housing change; equipment; work rolls; Steckelvalsverk; Lagerhusbyte; Utrustning; Arbetsvalsar;

    Abstract : Outokumpu Stainless AB operates in the production and development of stainless steels. In their hot rolling mill in Avesta there is a need to introduce an equipment to shift bearing housings on the steckel mill work rolls. Today this is accomplished manually with an overhead crane, jack, sledgehammer and pry-bar. READ MORE

  4. 13. 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.

  5. 14. Possibilities and limitations of exhaust gas analysis for expanded use in control of an AOD-converter

    University essay from KTH/Tillämpad processmetallurgi

    Author : Jonas Laxén; [2012]
    Keywords : : Exhaust gas analysis; off-gas analysis; dynamic model; carbon prediction model; AOD converter; carbon content;

    Abstract : The main purpose of the AOD-converter is to lower the carbon content in stainless steel production. The carbon content can be estimated by static theoretical models. It can also be estimated through dynamic models based on analysis of the exhaust gases from the converter. READ MORE

  6. 15. Examination of inclusion size distributions in duplex stainless steel using electrolytic extraction

    University essay from KTH/Materialvetenskap

    Author : Siamak Shoja Chaeikar; [2010]
    Keywords : Inclusion; SEM-INCA; Electrolytic Extraction; Duplex Stainless Steel; Three dimensional; Two dimensional;

    Abstract : Nowadays due to large demand for clean and defect-free steels, several techniques based on different characteristics of particles are applied to investigate the steel cleanness. Outokumpu Stainless AB in Avesta has performed extensive work in this field by applying several methods, which all of them have specific advantages and limitations. READ MORE
