In 1982, SSAB, Luleå Works, converted the blast furnace ferrous burden from an acid to an olivine pellet with a high Fe content. This change made it possible to gradually reduce the slag volume to 150 kg per metric ton of hot metal with huge positive effects on the blast furnace operation.

Mobility of blast-furnace slag
Steel in Translation, 2013Equipment for determining the mobility of blast-furnace slag in furnace operation has been developed and tested. On the basis of research at the casting doors of the blast-furnace shop, the MgO and Al2O3 content corresponding to high slag mobility is established. The dependence of the slag mobility on the hotmetal temperature, the basicity of the slag,

Viscosity of blast furnace type slags
Metallurgical and Materials Transactions B, 2003The effect of MgO, TiO2, or Fe2O3 on the viscosity of 40CaO-40SiO2-20Al2O3 (mass pct) slags has been measured by the rotating crucible viscometer. Viscosity of these quaternary slags decreased with an increase in the content of additive oxide. At the same content of additive oxide, the viscosity decreases from MgO, TiO2 to Fe2O3.

Use of converter slag in blast furnaces
Metallurgist, 1985Reducing the material content of products and making efficient use of material resources -especially metals -are particularly important at the current stage of economic development. In connection with this, metallurgists are faced with the task of increasing the efficiency of use of iron, manganese, and fluxes at all stages of metallurgical production ...

Structural aspects of blast furnace slag
Emerging Materials Research, 2013Interdependence of structure and viscosity of blast furnace slag is discussed based on the available literature. Emphasis is given to both, bridging tendency and network breaking/modifying tendency of the constituents. It is clearly pointed out that slag viscosity cannot be explained only by depolymerization through an increase in basicity, despite ...

Metallurgical industry produces slag as by-products. Iron blast furnace slag is the major non-metallic product consisting of silicates and aluminosilicates of calcium. They are formed either in glassy texture used as a cementitious materials or in crystalline forms used as aggregates. Other slags such as copper slag have pozzolanic properties and react

Slag wool manufacturing from blast furnace slag
2016Slag wool is the most expensive and valuable product of blast furnace slag processing. Slag wool is in great demand nowadays. The article highlights the factors influencing the mineral wool quality: chemical composition that determines the acidity of the module, the temperature of the molten slag and the required slag jet thickness consistency.
