Jul 29, 2010· We are the largest producer of sponge iron using non coking coal as a reductant and and are having the largest coal based plant in the world. We shall discuss in detail all technical aspects of coal base sponge iron making with particular reference to control of important process parameters to achieve quality sponge iron in this august gathering.

In a nutshell, COREX is a coal based SR (smelting reduction) process of making hot metal or pig iron by direct use of noncoking coal. The outputs can be used either by integrated mills or EAF (electric arc furnace) mills. The process gasifies noncoking coal in a .

It covers the history of the iron and steel production, the development of the COREX® plant and the influence of environmental restrictions and future perspectives for this ironmaking process. COREX® was the first industrial smelting reduction process just driven by normal coal, which is .

Iron making process in the blast furnace . lime stone.  Then oxygen is blown into the furnace then the coal is completely burnt into carbon dyoxide due to carbon percentage is available into the coal. coal ) continuosly through the top of the blast furnace. Working : When we supply the raw material (hematite.

Blast furnace iron making 14 Potential release routes from blast furnace iron making 15 Control of releases arising from blast furnace iron making 16 Noise issues (IPPC) 17 Energy conservation measures (IPPC) 17 Utilisation of surplus hot metal 17 Alternative iron making .

This is main source of iron, in Electric Arc Furnace process. There are some other raw materials like, ferroalloys, to adjust combustion of liquid steel, and the carbon .

The alternative iron making process may be required to satisfy the criteria such as the use of different coals, simplified material preparation, metal with little impurities, independent process steps, closed energy system, efficient pollution control and no waste generation.

Schenck Process produces perfectly coordinated technical weighing solutions for balancing pig iron internally between blast furnace and steel plant. These can be used in any build situation. Pneumatic Conveying technology can be used for the injection of fuel and additives into blast furnaces and fluxes into the continuous casting process.

early phases of the production chain: Iron making, the process of turning solid iron bearing materials into liquid hot metal (typically 1500°C, % Fe, % C, % Si, some additional trace elements), is a process, wh ich is known in its earliest form since thousands of years.

A blast furnace is usually built with a steel case and bricks made of magnesium oxide or other refractory material inside the case. The hot furnace cannot melt these bricks. The furnace is cooled with water running inside part of the case and bricks. The process of making iron is simple. Iron ore is basically iron oxide. Iron is made by ...

Feb 29, 2008· Free sample. This authoritative account covers the entire spectrum from iron ore to finished steel. It begins by tracing the history of iron and steel production, right from the earlier days to today's world of oxygen steelmaking, electric steelmaking, secondary steelmaking and .

Steel mill with two arc furnaces. Steelmaking is the process for producing steel from iron ore and scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium and vanadium are added to produce different grades of steel.

Gray iron is the most versatile of all foundry metals. The casting process can have a significant effect on the structure and properties of gray iron casting. Connecting you with high quality metal casting facilities.

Nov 09, 2014· Sponge iron making process. 6. SECONDARY AIR Secondary air is introduced axially in the direction of the gas flow The air supplied to the length of the kiln is metered for close control of temperature and gas atmosphere in the kiln Heating zone extends from 25% to 40% along length of the kiln and in the reduction zone.

Nov 27, 2016· Iron is malleable when hot, but when cold it is very brittle. Steel is made by mixing iron and carbon to make an alloy. Steel is much stronger, much harder and much less brittle than iron. This is because the carbon atoms, within the iron lattice,...

Cast Iron Production The Production of Cast Iron: Hargreaves Foundry employs traditional sand casting techniques enhanced by modern materials and technology. There are four stages in production; Design, Pattern Making, Mould Making and Casting. Design: converting ideas into solid metal requires a planned approach that takes into account the

Blast furnace ironmaking is still the dominant process for the production of iron from ore. Such a long and sustainable track record arises out of continuous development in design, intensification ...

The Pickling Process CSI's pickling line started up in late 1994, and typically processes two out of every three coils produced at the Hot Mill. Its primary function is to remove the thin layer of oxidized iron, or scale, that forms on the surface of the steel at the temperatures employed during hot rolling.
