Pig iron - Wikipedia

Pig iron is an intermediate product of the iron industry in the production of steel, also known as crude iron, which is obtained by smelting iron ore in a blast furnace.Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and otherIron manufacturing process pig iron,- Genuine chemistry,13-12-2018· PIG IRON AND CAST IRON. The manufacture of iron is based on the principle of reduction of iron oxide with carbon monoxide. This reduction process is carried out in a furnace called ‘blast furnace’. The iron ore is first washed concentrated roasted in order to remove impurities such as sulphur and phosphorus as oxides.US5238487A - Process for the production of pig iron and,,A process for producing pig iron is described, which contains a reducing shaft furnace 1 and a melting gasifier 2. The sponge iron produced from iron ores in the reducing shaft furnace is supplied to the melting gasifier and converted there into a pig iron melt. The gas produced in the melting gasifier is supplied directly via a line 4 as reducing gas to the reducing shaft furnace.

How to Manufacture Pig Iron: How Pig Iron is made?

(ii) To most of the nations which are producing pig-iron, the coke, which is used as fuel, is becoming either short or inaccessible. Following are the other alternative methods of pig-iron manufacture: (1) Electric reduction furnace (2) Low shaft blast furnace (3) Sponge iron process.Pig Iron Manufacturing Process - 911metallurgist,Table of ContentsElectric Furnace Production of Pig SteelMaking Pig Iron by Electric Furnace Regulation of CarbonPig Iron ImpuritiesLoss of Iron in the SlagAdaptability of the Process to Continuous OperationCost of Production of Pig IronPig Iron At the beginning of the use of the electric furnace, for the manufacture of calcium carbide and ferro-alloys, experimental work was conducted in it,Pig Iron | International Iron Metallics Association,15-03-2017· Pig iron is the metallic ore that contains 90% of iron. Pig iron is used for making steel and pure iron units. It has very high carbon content along with silica and another constituent of dross.

The product of the blast furnace is pig iron, which contains 4-5 percent carbon and usually some silicon. To produce a forgeable product, a further process was needed, usually called “fining” rather than “refining. ” Starting in the 16th century, this process was performed in a finery forge.Iron Production - Chemistry LibreTexts,The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first separated from the gangue and then converted to pure iron. This is accomplished by the method of pyrometallurgy, a high temperature process.

Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steel-making process. Wrought iron: If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has little structural strength.Production of iron and steel - SlideShare,27-04-2015· 4/27/2015 7 Production of Pig – Iron process 1.

If you want to do anything with it, you have three options. First, you can melt it, mix it with slag and hammer it out to eliminate most of the carbon (down to 0.3 percent) and create strong, malleable wrought iron.
