Steel is made primarily in a two-step process. In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are ...

The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a ...
The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and …
Galvanizing Process. Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc.
iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties.

A flowchart is a graphical representation of an algorithm.it should follow some rules while creating a flowchart. Rule 1: Flowchart opening statement must be 'start' keyword. Rule 2: Flowchart ending statement must be 'end' keyword. Rule 3: All symbols in the flowchart must be connected with an arrow line.
Steel manufacturing Principle of the Bessemer Process. The main raw materials for Steel production in a blast furnace are Iron ore, limestone, coke, and some scrap steel. These materials are charged into the blast furnace from the top and converted into molten pig iron. Next, a current of air is blown through the molten pig iron containing ...
Platinum (element #78, symbol Pt) is a dense, silvery-gray metal. The platinum group of elements consists of metals with similar physical properties as platinum and these elements are among the rarest in the Earth's crust. They have high melting points, are dense or heavy and are non-reactive with other elements.

In the most basic sense, flowchart or flow chart, is a type of diagram that describe processes. . Flowchart represents information or processes as boxes, lines, and text. The boxes represent activities, the lines (or flowlines ) represent the workflow that connects them, and the text represents what happens at each activity.
1.2 Process Description. The blast furnace process has auxiliary equipment associated with it. This auxiliary equipment and the gaseous pathways inside a blast furnace process are shown in Fig. 2. The blast furnace process can be briefly described as follows. Iron oxides, flux agents, and metallurgical coke are added to a skip car at the …
Abstract. Ferroptosis is a recently recognized form of regulated cell death. It is characterized morphologically by the presence of smaller than normal mitochondria with condensed mitochondrial membrane densities, reduction or vanishing of mitochondria crista, and outer mitochondrial membrane rupture. It can be induced by experimental …
