The traditional blast furnace route is the worlds most important process for the production of hot metal.A wide range of different mathematical models has been developed in the past.
Direct reduced iron dri process.In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron dri process secondary route.The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

The flows of burden and gas in the blast furnace shaft strongly affect the fuel economy of the process.An optimal gas flow distribution, which is obtained by controlling the burden distribution, leads to a high utilization degree of the reducing gas, smooth burden descent, and little wear of the furnace lining.
Figure 5 process flow through no.5 blast furnace 5.4.2 blast furnace the blast furnace is a vertical shaft of circular cross-section and stands approximately 40 m high although the overall facility approaches 100 m.The vessel is internally lined with cooling elements and refractory bricks and blocks.
Steel-making the basic oxygen process.Impurities in the iron from the blast furnace include carbon, sulfur, phosphorus and silicon.These have to be removed.Removal of sulfur sulfur has to be removed first in a separate process.Magnesium powder is blown through the molten iron and the sulphur reacts with it to form magnesium sulfide.
Many researchers are working on adapting the existing blast furnace process to meet the new challenges.Modelling has played a crucial role in new adaptations of the process.The present review has been dedicated to historical developments of blast furnace modelling.
The blowing-in process is carried out in several steps fig 1 which consist of i drying out the lining, ii filling of the blast furnace with a specially arranged high coke blow-in furnace charge, iii igniting of the coke or lighting of the blast furnace, and iv gradually increasing the hot blast.
Generalized process flow diagram a general flow diagram for the production of raw steel from iron ore is presented in exhibit 2.In general, the process involves 1 beneficiation of the iron ore, 2 either direct-reduction or reduction in an iron blast furnace, 3.
