  1. 1. Investigations of thermophysical properties of slags with focus on slag-metal interface

    Detta är en avhandling från Stockholm : KTH

    Författare :Luckman Muhmood; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slags; density; diffusivity; sessile drop; interfacial velocity; interfacial viscosity; interfacial dilatational modulus; interfacial shear viscosity; TECHNOLOGY Chemical engineering Metallurgical process and manufacturing engineering Metallurgical process engineering; TEKNIKVETENSKAP Kemiteknik Metallurgisk process- och produktionsteknik Metallurgisk processteknik;

    Sammanfattning : The objective of this research work was to develop a methodology for experimentally estimating the interfacial properties at slag-metal interfaces. From previous experiments carried out in the division, it was decided to use surface active elements like sulfur or oxygen to trace any motion at the interface. LÄS MER
