Download citation on researchgate | applying an expert system to the silicon control in the blast furnace | this article shows the possibilities of applying the fuzzy sets in simulating the activity of the operator at a blast furnace and indicates, consequently, the possible concepts in compiling an expert system by the application of the fuzzy set. Silicon content in hot metal it is well-known that the silicon content mainly comes from ash content of coke in blast furnace process and its content is also dependent on the volume of blast furnace there is a quantitative relationship between them, which is shown in table 1 it can be clearly seen that the larger blast furnace is, the lower. Fly ash, ground granulated blast-furnace slag, silica fume, and natural pozzolans, such as calcined shale, calcined clay or metakaolin, are.

Blast furnace modern design – modular construction this article summarises the results of a comparison of two modern blast furnace designs these designs include similar hearth, upper stack and throat armour technologies, but differ on the lining selection for bosh, belly and stack the þrst design includes copper plate coolers, graphite and silicon. The control of a blast furnace system often means to control the hot metal temperature and silicon content thus, modeling of silicon content is crucial for blast furnace thus, modeling of silicon content is crucial for blast furnace. The efficient control of the blast furnace process relies on accurate and fast analysis of co and co2 concentration in the top gas ms has a distinct advantage over the more traditional technique of infrared analyzers due to the reduced sample time, increased accuracy through automatic and extensive calibration techniques, and long-term stability.
The type of furnace now used to make silicon, the electric arc furnace, was first invented in 1899 by french inventor paul louis toussaint heroult to make steel. Keywords: pyrometallurgy, blast furnace, slag viscosity, slag liquidus temperature, phase equilibria abstract – the viscosity of molten slag in blast furnace operations is an important process variable, influencing the rate and location of reactions inside the furnace, as well as the ease with which the final slag could be removed from the furnace. The control of a blast furnace system often means to control the hot metal temperature and silicon content thus, modeling of silicon content is crucial for blast furnace.
Silicon content ([si] for short) of the molten metal is an important index reflecting the product quality and thermal status of the blast furnace (bf) ironmaking process since the online detection of [si] is difficult and larger time delay exists in the offline assay procedure, quality modeling is required to achieve online estimation of [si. Blast furnace cooling system function of blast furnace cooling system is to cool the furnace shell and prevent from the overheating and subsequent burn through.
