9th International Conference on Modeling and Simulation of Metallurgical Processes in Steelmaking - STEELSIM2021

A novel solution procedure is developed for the phase field-based simulation of dendritic solidification in Fe-C alloys. The adaptive solution procedure is based on the dynamic quadtree domain decomposition which divides the computational domain into quadtree sub-domains of different size. Each quadtree sub-domain has its own distribution of computational nodes in which the meshless radial...

Continuous casting of thin steel slabs is a cutting-edge technology in iron and steel industry. Electromagnetic Braking (EMBr) technique is widely implemented into thin slab casters to reduce defects caused by strong turbulence in the mold. A slab-casting Strand Electromagnetic Stirring (SEMS) system was developed to control heat transfer in the strand. Sophisticated phenomena, including...

The blockage of bottom blowing tuyere(s) has a significant impact on the refining efficiency in the converter steelmaking process. In this paper, the effect of different arrangements of tuyere(s) blockage on the mixing efficiency was investigated in a 100 t converter with six bottom tuyeres. Both hydraulic experiment and numerical simulation were employed and their results agree well in terms...

Steel manufacturing is a long and complicated process involving iron-making, refining, casting, rolling, etc.; the result, hundreds of processing parameters all with a potential influence on the mechanical properties of final product. This complexity results in significant challenges in the correlation of input parameters with output mechanical properties.

In this work, we applied both a...

Ladle furnace (LF) refining is one of the most popular secondary refining processes to produce clean steel and largely takes the responsibility in the whole steelmaking process. The performance of slag dramatically determines the refining efficiency. In order to realize the precise control of the composition content for refining slag to ensure the optimal performance of CaO-SiO2-MgO-Al2O3 slag...

The steelmaking industry plays an important role on the global anthropogenic $CO_2 $ emissions, accounting to 7 % of all global emissions. In addition, this industry also produces many by-products whose direct disposal without a proper treatment represents an environmental hazardous. In recent years, the recycling of these by-products is gaining increased relevance, to achieve a more...
