Mechanism of Hot Metal Dephosphorization by Injecting Lime Base Fluxes into Bottom Blown Converter

Large Eddy Simulation of Bubbling-Jetting Transition in a Bottom Blown Copper Converter

In this work the isothermal transition from bubbling to jetting regime in a bottom blown Peirce-Smith copper converter is numerically studied, varying the air jet injection velocity from 5 to 100 m s -1 . Large Eddy Simulation turbulence model is employed in the computer simulations to obtain transient, rather than averaged, phase distributions. For low injection velocities the bubbling regime ...

The Effect of CaF2 Content in Hot Metal Pretreatment Flux Based on Lime

This research was conducted for the purpose of studying the effect of CaF2 content in the composition of hot metal pretreatment flux, based on lime. It was followed in regards to the importance of fluorine amount decrease in hot metal pretreatment and steel making processes. For this purpose, lime based fluxes including 40, 30, 20 and 10 percent calcium fluoride were prepared and hot metal pret...

Model-based Slopping Detection in a Top-blown Steel Converter

The most common steel-making process in the world is the Lintz-Donawitz converter. During operation, a slag foam is created to improve the converter performance. Problems arise when the foam level exceeds the height of the vessel and overflows, causing metal loss, process disruption and environmental pollution. The goal of this study is to design a model-based algorithm exploiting real-time pro...
