HOT METAL (LIQUID IRON): It is the hot, liquid, metallic iron product obtained upon reduction of iron ore (normally in Blast Furnace or in Corex Furnace). It contains about 9394% Iron (Fe) and other elements/impurities like Carbon (4%), Silicon (~1%), Manganese (+1%) Sulphur, Phosphorus etc. Hot metal is the primary input for production of ...
Steps Involve in the Manufacturing Process of TMT Bars: The raw material is placed in the furnace and treated with hot gas while in its liquid form. The molten state of iron is preprocessed and converted into steel. The liquid form of steel is then poured into a casting machine to get the billets. At this point, the iron ore gets purified, and ...

The common raw material for iron and steel industry is iron ore. The primary raw material used to manufacture steel is iron. All steel alloys are primarily iron and % carbon by weight. Iron ore, coke and calcite (lime) are added to a blast furnace to produce molten iron. This iron is used as the raw material for steel manufacturing ...
Steelmaking occurs by processing raw materials in a blast furnace to produce liquid iron. A blast furnace is used to remove oxygen from iron ore. This process is known as 'reducing' and involves injection of hot air into a continuous feed of coke, sinter and lime. The result is liquid iron which is then transported to the Basic Oxygen furnace.

Iron ore is, therefore, essential for the production of steel, which in turn is essential in maintaining a strong industrial base. 98% of mined iron ore is used to make steel. Iron ore is mined in about 50 countries. The majority of iron ore is mined in Brazil, Australia, China, India, the US and Russia.
[1] Steelmaking is one of the most carbon emission intensive industries in the world. As of 2020, steelmaking is responsible for about 10% of greenhouse gas emissions. [2] To mitigate global warming, the industry will need to find significant reductions in emissions. [3]
The iron and steel industry currently sells the slag byproduct for use as an aggregate, filler or raw material in readymixed concrete, concrete products, asphaltic concrete, roadway materials, construction fill, clinker, railroad ballast, roofing, mineral wool insulation and soil conditioners.
Raw material. Iron and Steel industry uses a large quantity of heavy and weight losing raw material, so its location is primarily guided by the availability of raw material. Most of the iron and steel plants of India such as Jamshedpur, Burnpur, Durgapur, Rourkela, Bhilai, and Bokaro are located in Jharkhand, West Bengal, Orissa and Chhattisgarh.
With a century of experience in sourcing raw material through scientific research development and sustainable mining, our longterm strategy has been designed to develop the existing raw material resources and achieve its security across global operations. Iron Ore and Coal. Iron Ore mining is an integral part of steel making at Tata Steel.
The raw materials for producing molten iron are iron ore, coking coal and fluxes (materials that help the chemical process) mainly limestone. The hot air blast to the furnace burns the coke and maintains the very high temperatures that are needed to reduce the ore to iron. The reaction between air and the fuel generates carbon monoxide.
The principal raw materials required for the HIsmelt process are iron ore fines, noncoking coal and fluxes (limestone and dolomite). The HIsmelt process is very flexible due to its ability to utilize cheaper and more abundant raw materials, including steel plant wastes and high phosphorus ore, together with high and low volatile coals.
Iron orebearing material and metallurgical coal is typically and most economically delivered to steelmaking sites by large, oceangoing ships. When ships arrive, raw materials are unloaded using huge cranes with opening jaws that grab the raw material from the hold of the ship and then deposit it in huge piles. Steel plants that are situated inland need to bring raw materials in by land ...
worldsteel expects that global endoflife scrap availability will reach about 600 Mt in 2030 and 900 Mt in 2050, a growth of more than 500 Mt in one of our main steelmaking raw materials in the next 30 years. The steelmaking process is able to remove most impurities that may be present in scrap steel. Hence 'downcycling' of steel scrap ...
As indicated in Fig., the raw materials used in the BFBOF system include iron ore, coal, fluxes (mainly limestone and dolomite), recycled steel scraps, and alloys. On average, this process uses approximately 1400 kg (3086 lb) of iron ore, 800 kg (1764 lb) of coal, 300 kg (661 lb) of flux, and 120 kg (265 lb) of recycled steel to produce ...

Iron ores are found in various geologic environments, such as igneous, metamorphic, or sedimentary rocks, and can contain over 70% iron, with many falling in the 5060% range. Combined with other materials like coke and limestone, iron ore is primarily used in steel production. Today, almost all (98%) iron ore is dedicated to steelmaking.
As a consequence of a tight raw material supply for the blast furnace, the COREX process enables operators to produce hot metal based on raw materials that are still not tight in supply and are available at "reasonable" prices. Direct reduced ironis a process in which iron ore is reduced to the solid state or by gaseous reducing agent. The ...
