  1. 11. Thermo-Mechanical Modelling of Hot Strip Coil Cooling Process

    Författare :Mats Karlberg; Daniel Berglund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : In hot rolled steel strip production the processed material are after the cooling section coiled into coils. Coils do normally weigh around 20 tons with a diameter of 2 m and heights equal to the strip width e.g. 0. LÄS MER

  3. 12. Theoretical magnetohydrodynamic and solidification studies of continuous strip casting

    Författare :Hans B. Löfgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The continuous casting of steel strips has been under investigation and development for several decades. The aim of this development is to be able to cast steel strips in a thickness range from 1 to 10 mm. Today, there are basically two such methods: the single-belt caster and the twin-roll caster.

  5. 14. Some aspects on lubrication and roll wear in rolling mills

    Författare :Mohammed Tahir; KTH; []
    Nyckelord :strip rolling; lubricants; environment; roll wear modeling. Production campaigns; regression analysis;

    Sammanfattning : The thesis is focused on lubricants and roll wear in striprolling.Regarding lubricants, the possibility of introducing newones, which are less detrimental towards environment, isstudied in laboratory scale. This is done for cold rolling,both of an Al- alloy and a low carbon steel. LÄS MER

  7. 15. Analysis of Planar and Circular Cylindrical Multilayer Structures with Application to Soft and Hard Surfaces

    Författare :Zvonimir Sipus; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antennas; periodic surfaces; integral equations; approximate boundary conditions; soft and hard surfaces; Green s functions; corrugated surfaces; moment method; periodic metal strips; multilayer structures; EFIE; microstrip antennas; spectral domain analysis; group representation theory; strip scatterers;

    Sammanfattning : This thesis deals with the analysis of planar and circular cylindrical multilayer structures, such as strip-loaded dielectric layers, corrugated surfaces and microstrip antennas. In particular, we study corrugations and strip-loaded grounded dielectric slabs when they are used to realize soft and hard surfaces. LÄS MER
