SOME CONSIDERATION OF BLAST FURNACE OPERATION.

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...

Application of Large Scale Database-based Online Modelling on Blast Furnace Operation

A practical method of JIT modelling for a blast furnace process data whose characteristics are very complicated physical phenomena and stiff nonlinear process are studied. The proposed method is composed of severely selecting process data variables by stepwise method and searching the past similar data in quantized topological space constructed by the selected variables. The effectiveness of th...

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...

Reheat furnace scheduling with energy consideration

This paper focuses on the reheat furnace scheduling problem (RFSP) which is to assign the slabs to the reheat furnace, make the slab sequence for each furnace and determine the feed-in time and the residence time for each slab in order to reduce the unnecessary energy consumption reflected by minimising the objective under consideration. Differing from the traditional scheduling problem, the ac...
