1. 1. Interaction between pellet properties and blast furnace operation

   Författare :Ulrika Leimalm; Gabriella Tranell; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Sammanfattning : The raw material properties of iron-bearing material and coke have a significant impact on the blast furnace (BF) process. The raw materials are designed and chosen to achieve smooth BF operation but the operational parameters can be simultaneously modified to meet properties of selected raw materials. As the pre-set process conditions change, e. LÄS MER

3. 2. Pellet reduction properties under different blast furnace operating conditions

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

   Sammanfattning : One of the aims of modern blast furnace (BF) ironmaking is to reduce coke consumption. One way is to increase the injection of reduction agents, such as pulverized coal. An increase in pulverized coal injection rate (PCR) will affect the blast furnace process and the conditions for iron oxide reduction. LÄS MER
