2.1 Midrex Process. Midrex is the most successful gas-based DR process; it is a continuous process. It is basically a countercurrent process where a hot and highly reducing gas (95vol.% of this gas mixture being hydrogen and carbon monoxide with a ratio of H 2:CO varying from 1.5 to 1.6) reduces lump iron ore or pellets to metallic iron as …
This series follows a cast iron or steel product through the metal casting process in a traditional foundry. Iron melts at 2750°F and steel at 2500°F. Casting is the process of creating metal objects by pouring liquid metal into molds, where it cools and hardens into the mold's shape. Although the premise is simple, there are many ...
Steel production is a 24-hour-a-day, 365-day-a-year process, dependent on a consistent supply of raw materials and huge amounts of energy. According to the World Steel Association, world crude steel production has increased from 851 million tonnes (Mt) in 2001 to 1,606 Mt in 2013 and world average steel use per capita has steadily …
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …

Easiest to beneficiate are haematite ores (bottom part of the picture). In simplified terms, the process steps comprise "Mine-Crush-Screen-Sell" and are also described as DSO process (DSO = high-grade direct shipping …
This document provides a process flowchart for a coal based Direct Reduced Iron (DRI) / Sponge Iron Plant. The flowchart shows that iron ore is ground and screened before being fed into the plant. Coal is also ground and screened in separate processes before being fed into primary and secondary crushers. Water and chemicals are added before the …
A flow chart that illustrates the kinds of slag produced for each process of iron and steelmaking is shown in Figure 1. This paper critically examines utilization of steel slags for road ...
The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten …
Cast iron is one of the initial products in the manufacturing process, and its flow chart shows the importance of cast iron in the steel industry. Cast iron belongs to the family of ferroalloys and is one of the most widely used alloys in the industry. Iron, carbon and silicon are the main elements of this alloy.
When sufficient hot metal has formed at the bottom of the furnace, we drill open the furnace and tap the iron. The hot metal is collected in torpedo-shaped train waggons and is then ready for transport to the BOS (Basic Oxygen Steelmaking) plant next door. The converter in the BOS Plant turns the pig iron into steel.
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 …
The Iron making is necessarily a reduction process, as far as the chemical theory is concerned, where reduction of the iron ores takes place to produce metallic iron. • Iron ores: Generally in Oxides: Hematite (Fe 2 O 3), Magnetite (Fe 3 O 4) Mass number (55.85) Density=7.874g/cc Atomic number (26) m.p= 1538° C b.p= 2861° C Fe Iron (Latin ...

What is a Flowchart? A flowchart is a visual representation of the sequence of steps and decisions needed to perform a process. Each step in the sequence is noted within a diagram shape. Steps are linked by …
The Steel Making Process: An Overview. The process of making steel is a captivating sequence, marked by precision and careful control. Let's look at an overview of this process, which typically includes the following key stages: Iron Making, Steel Making, Continuous Casting, and Rolling. Firstly, the iron-making phase involves converting iron …
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
