Crystallization of Synthetic Blast Furnace Slags Pertaining to Heat Recovery
Heat recovery from blast furnace slags is often contradicted by another requirement, to generate amorphous slag for its use in cement production. As both the rate and extent of heat recovery and slag structure are determined by its cooling rate, a relation between the crystallization kinetics and …

Neural network based modeling and data mining of blast furnace operations
Industrial production processes have traditionally been predicted using models whose structure is determined from domain specific knowledge. Steel production is an ex.ample of such a process, where conventional modeling techniques are based on knowledge of the materials and reactions involved. …

CFD-DEM MODELLING OF PARTICLE-GAS REACTIVE FLOWS AND ITS APPLICATION IN BLAST FURNACE REGIONS
The ironmaking blast furnace involves complex particle-gas reactive flows, which are crucial for determining the efficiency and effectiveness of iron production. A fundamental understanding of these intricate reactive flows is essential for optimizing furnace operation and performance. This thesis …

Effect of blast-furnace slag as cement replacement on hydration, microstructure, strength and durability of concrete
… reduced. This PhD thesis focuses on the use of blast-furnace slag (BFS) as cement replacing material. Blast-furnace slag, a by-product of the steel production, obtains latent-hydraulic properties after rapid cooling and can thus replace clinker in cement. In EN 197-1 (2000), three types of slag …
