  1. 11. An Experimental Study of Liquid Steel Sampling

    Författare :Ola Ericsson; Pär Jönsson; Andrey Karasev; Malin Hallberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid steel sampling; slag protection; filling velocity; solidification rate; sample homogeneity; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Sammanfattning : Sampling of liquid steel to control the steel making process is very important in the steel industry. However, there are numerous types of disposable samplers and no united standard for sampling. The goal in this study is to investigate the effect of slag protection type and sample geometry on sampling parameters and sample homogeneity. LÄS MER

  5. 14. Rapid solidification behaviour of Fe and Al based alloys

    Författare :Sathees Ranganathan; Hasse Fredriksson; Zhongyun Fan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rapid solidification; Melt spinning; Metastable phases; Fe based alloys.; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Sammanfattning : Rapid solidification experiment on Fe-Cr-Mo-Mn-Si-C alloy was performed to investigate metastable phases formed during the solidification. A wide range of cooling rate was used to analyse the sample from melt spinning technique (~107 K/s) to water quenching method (~102 K/s). LÄS MER

  7. 15. A Study of the Heat Flow in the Blast Furnace Hearth Lining

    Författare :Maria Swartling; Pär G. Jönsson; Xuegong Bi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blast furnace; heat transfer; mathematical model; experimental; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Sammanfattning : The aim of the present thesis was to study the heat flows in the blast furnace hearth lining by experimental measurements and numerical modeling. Thermocouple data from an operating furnace have been used throughout the work, to verify results and to develop methodologies to use the results in further studies. LÄS MER
