The present paper reports a statistical analysis of the performance of the blast furnace number X at the Bhilai Steel Plant over a period of sixteen years with the special reference to the quality and consumption of sinter . The variation in basicity and consumption of sinter, for the blast furnace data considered , is wide. The range of data covers high level to almost nil amount of raw limest...

Many of the data sets extracted from real-world industrial environments are time series that describe dynamic processes with characteristics change over time. In this paper, we focus on fouling process in an furnace, which corresponds to a non-stationary multivariate seasonal component, non-homogeneous cycles and sporadic human interventions. We aim forecast evolution temperature inside furnace...

INTRODUCTION This report presents the results of two trials conducted with the Blast Furnace Granular Coal Injection System at Bethlehem Steel Corporation's Bums Harbor Plant. The trials were conducted using granulated and pulverized high volatile coal from Colorado. The first trial was conducted to quantify the effect that a high volatile western coal, Colorado Oxbow, has on the blast furnace ...

The difficulty in measuring load temperatures inside reheating gas furnaces may be circumvented by appropriate use of on-line numerical models. In this article we describe a model of pusher furnaces, used to reheat steel slabs. The model uses thermocouple measurements at fixed positions inside the furnace to calculate the temperature of the combustion products, and takes into account radiative ...

This paper describes the adsorption of two organic (acetic and citric) acids on the blast furnace sludge, a representative by-product of the steelmaking industry. By PIXE, XRD, BET and SEM methods, it was shown that blast furnace sludge is a complex heterogeneous material with a specific surface area of s = 31.46 m g, composed mainly of amorphous phase (w = 76.2 %), calcite (w = 9.9 %), magneti...

In this paper, an enhanced version of whale optimization algorithm (EWOA) is presented to be applied in adaptive control techniques as a parameter tuner. One weakness point scheme the low efficiency its objective function. Balloon effect (BE) modification introduced increase function method and ability controller deal with system problems consequently. Controlling temperature electric furnaces ...

Mathematical model for the integrated thermal apparatus was developed. It consists of program modules from which individual furnace model can be generated. For the model generation elementary balance method was used. Generation of the individual model includes model formulation and parameters determination. Model formulation is based on first principles, heuristics and empirical results. Parame...

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...
