  1. 31. Studies on the cold bonded briquettes of iron and steel plant by-products as burden material for blast furnaces

    Författare :Maneesh Singh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : During the various stages of iron & steel production a number of iron bearing by-products are generated. These by-products can be made into cement bonded agglomerates for use as burden material for blast furnaces. LÄS MER

  3. 32. Controlled dust separation : theoretical and experimental study of the possibilities of controlled dust separation in copper producing processes

    Författare :Caisa Samuelsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Dust is generated in high temperature processes, such as incineration plants, power plants and within the metallurgical industry. The amount of dust generated, chemical and mineralogical composition of the dust as well as physical properties will largely depend on the process generating the dust but also on the off gas system used.

  4. 33. Alternative reducing agents in metallurgical processes : Experimental study of thermal characterization of shredder residue material

    Författare :Samira Lotfian; Noureddine Menad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Coal used in metallurgical processes can participate in reduction reactions to produce metals and alloys from oxides. Base metals production leads to generation of slag, which contains valuable metals that can be recovered and recycled. There are several options to treat the slag, depending on the metal content in the slag. LÄS MER

  5. 34. Experimental studies on treatment and recycling of pickling sludge generated in stainless steel production

    Författare :Ping Ma; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Pickling sludge generated in the stainless steel industries contains large amounts of calcium fluoride and water and relatively small amounts of metals. Therefore, such sludge is difficult to be directly recycled back to the EAF process and would be harmful to the environment if deposited as landfill for a long term. LÄS MER

  7. 35. Mathematical modelling of fluid flow and heat transfer in steel ladles

    Författare :Pan Yuhua; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : In this thesis work, three mathematical models, each of which is suitable for simulating a particular process in the operation of steel ladles, have been developed. Firstly, by using a finite-difference mathematical method (FDM), a one-dimensional numerical model for calculating heat transfer through ladle wall, bottom and top slag layer was established. LÄS MER
