Moreover, Gantt chart of "quasi-laminar flow" production pattern was drawn. It is shown that the relative "order degree" of the "quasi-laminar flow" production pattern rises, which is conductive to production scheduling and ladle operation turnaround in comparison with "turbulence" production pattern.
The converter in the BOS Plant turns the pig iron into steel. Here, we add oxygen and used steel, or steel scrap. Scrap ensures that the temperature in the converter does not rise too high and it is sustainable: empty tins, old cars, refrigerators and even bridges are reused. Steel is a pre-eminently circular product: it can be endlessly reused.
3. Results and discussion In this part, we used the software e! Sankey to show the material flow of conventional ISM, ISM with OBF and ISM with COREX as is shown in Fig. 4 - 6. This software can clearly show the distribution of material flow of different iron and steel production process through different line width and colors. As Fig. 4.

According to the material, steel can be divided into two categories: "carbon steel" and "stainless steel and alloy steel". The upstream of the carbon steel industry chain includes coal, iron ore, and scrap steel raw materials, as well as large steel billets, small steel billets, flat steel billets, steel ingots, etc. made from the above raw materials through blast furnace or …
The production of steel products from iron ore involves two separate steps: ironmaking and steelmaking. Each of these is described in detail below. Iron blast furnaces prod uce molten iron (pig iron) that can b e cast (molded) into products ; however, the majority of pig iron is used as the mineral feedstock for steel production. Steel
Steel Manufacturing Process Flow Chart - Free download as Word Doc (.doc / .docx), PDF File (.pdf), Text File (.txt) or read online for free. This document describes the process of obtaining iron and steel using a flow diagram. The process begins with the extraction of minerals from the ores, which are transported to a blast furnace where they are separated into pig iron and slag.
