The oxidant used in this method of iron ore steelmaking is oxygen. Air is blown into molten raw iron ore to oxidize impurities such as silicon and manganese. In the process of oxidation, a large amount of heat (containing 1% silicon can increase the temperature of raw iron ore by 200 ℃) can make the furnace reach a high temperature

Production. Producing top-quality steel involves many steps that require precision and our employees’ expertise. Here is an overview of our manufacturing process. ... Scrap metal and iron ore are melted with very hot electrodes (about 1,650 degrees Celsius). ... A billet
Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route. Both processes are being continually improved
In this process recycled scrap steel is also added to the molten iron in a converter. Coke serves two purposes in the BF - Firstly it provides heat energy on combustion and secondly carbon for reduction of iron ore into iron
Billets are hot charged in rolling mill to manufacture TMT bars. Sree Metaliks Limited is a leading iron mining company in India with one of the best grade of iron ore which is used as raw material to make sponge and billets. Our billets are available from 100/100, 125/125 to 160/160 sizes and have a high consistency of the product
Apr 10, 2020 Iron products evolved during this time, beginning with blacksmiths producing wrought iron goods. These tradespeople learned to heat up iron ore, and using a hammer-and-anvil process, the blacksmiths would remove impurities from the metal and produce a durable and malleable final iron

The IFCON process, developed by ISCOR in South Africa, is capable of producing steel directly from coal and iron ore. 1 In this process, coal and ore are added continuously to a channel type induction furnace containing a slag-metal bath. Electrical energy is supplied by the induction furnace for heating and stirring the bath
Apr 04, 2012 The ironmaking process in the blast furnace is a heat and mass transfer process, and the furnace can be divided into different zones according to physical and chemical state of the feed and temperature. Figure 1.1.5 illustrates various zones of the blast furnace and feed distribution and materials flow [13].Corresponding to each temperature interval, typical reactions will take place
The iron ore shown to the right was excavated from Sk gar, a Viking-age iron-making site in Iceland. The larger piece is about 2cm (less than 1in) in the long dimension. Sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smelt
The iron ores, in particular high-grade or upgraded ores, are reduced to sponge iron by extracting the oxygen they contain, thus obtaining a ferrous material that replaces scrap. Iron and Steel Production. The world’s pig iron production was 578 million tonnes in 1995 (see figure 73.1). Figure 73.1 World pig iron production in 1995, by regions
1. Iron ore, coke, and limestone are carried up to the top of the furnace often with skip cars. 2. The blast furnace may be more than 250 feet tall. The inside is about 30 feet wide. The outside of the furnace is a steel shell and inside of the furnace is lines with a refractory material; usually fire-resistant brick
Process of sustainable and efficient production of iron ore pellets. Join us and Dr Jan Paul Lampke, Head of Sales & Projects, Haver Engineering Gmbh, for a live webinar on Monday, 15th June at 03:00 PM (IST), 5:30 PM (Singapore time), 1:30 PM (Dubai Time), as he explains how SCARABAEUS pelletizing discs can be used for sustainable and
The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe2O3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Major reducing agent in the BF is the carbon monoxide gas(CO) generated by the oxidation of the carbon(C) in coke
