  1. 6. An Approach for Evaluation of Brick Lining's Mechanical State in Rotary Kilns

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Dmitrij Ramanenka; Luleå tekniska universitet.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Production of many materials requires treatment at elevated temperatures. Calcination and sintering are some of the important heat treatment procedures which are typically performed in so-called rotary kilns. These, not very well-known treatment vessels, have a significant impact on our everyday life. LÄS MER
