Dynamics Characteristics of Blast Furnace Shell

Blast Furnace Dynamics Using Multiple Autoregressive Models with Exogenous Inputs

Autoregressive models with exogenous inputs are useful tools for analyzing systems with unknown dynamics, but are limited by the assumption that the relations between inputs and output(s) are linear. For complex systems with nonlinear or abruptly changing dynamics it is possible to modify the technique by allowing for multiple local models and designing a strategy for switching between them. A ...

Ground Granulated Blast Furnace Slag

1. Ground Granulated Blast Furnace Slag Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron o...

Comparison of Local Stress Values Obtained by Two Measuring Methods on Blast Furnace Shell

P. Bigoš, J. Kuľka, M. Mantič, M. Kopas , Faculty of Mechanical Engineering, Technical University of Košice, Slovakia This paper describes measuring of time behaviour specified for local stress increments on the blast furnace shell that were performed using strain gauge sensors. These results are compared with values obtained by means of the second specific measuring method. There is also prese...

Ann Based Prediction of Blast Furnace Parameters

The Study of Ion Adsorption by Amorphous Blast Furnace Slag

In this study, the blast furnace slag was used as absorbing bed and then, its ionic adsorption was studied. For this reason, various experimental parameters such as pH, contact time and the primary ion concentration were investigated. The remaining concentrations of ions such as; Mn2+ and Fe2+ in water were measured by atomic adsorption spectroscopy. The chemical and p...
