Pig Iron

Pig Iron

The traditional shape of the molds used for pig iron ingots is a branching construction shaped in sand, with many particular person ingots at right angles to a central channel or “runner”, resembling a litter of piglets being nursed by a sow. When the steel had cooled and hardened, the smaller ingots (the “pigs”) had been simply broken from the runner (the “sow”), hence the name “pig iron”. As pig iron is intended for remelting, the uneven size of the ingots and the inclusion of small amounts of sand triggered solely insignificant problems considering the ease of casting and dealing with them.

what is pig iron

This is achieved by remelting pig iron, often along with substantial portions of metal and scrap iron, eradicating undesirable contaminants, adding alloys, and adjusting the carbon content material. Some pig iron grades are suitable for producing ductile iron. These are excessive purity pig irons and relying on the grade of ductile iron being produced these pig irons may be low within the elements silicon, manganese, sulfur and phosphorus. These kinds of pig iron are used to dilute all the elements in a ductile iron charge which may be harmful to the ductile iron course of. iron tapped from a blast furnace and cast into pigs in preparation for conversion into steel, forged iron, or wrought iron.


It was the first to introduce low phosphorous foundry-grade pig iron in India. The Company additionally commissioned an 800,000 tones’ sintering facility that may enable the PID to partially meet its iron ore requirement with sintered iron ore fines, leading to significant value savings and growing efficiencies. Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electrical furnaces. Pig iron, crude iron obtained directly from the blast furnace and cast in molds.

Pig iron has a really excessive carbon content material, usually 3.5–four.5%, together with silica, Manganese, Sulphur, Phosphorus, Titanium and different hint elements. iron within the chemical state in which it exists when tapped from the blast furnace, without alloying or refinement. Pig iron incorporates no less than 92% Fe and has a really excessive carbon content, sometimes three.5 – 4.5%. integrated steel mills – with iron that is surplus to their internal requirements and cast into ingots and sold to the service provider market. We produce compositions inside pretty slender ranges of specifications with the target of optimizing buyer’s prices as a result of non-addition of components, standardization of process parameters and minimization of rejects.

Dictionary Entries Close To Pig Iron

Smelting and producing wrought iron was identified in historic Europe and the Middle East, nevertheless it was produced in bloomeries by direct discount. Furnaces such as Lapphyttan in Sweden could date back to the twelfth century; and a few in Mark to the 13th. It remains to be established whether these northern European developments derive from Chinese ones. Wagner has postulated a attainable hyperlink via Persian contacts with China alongside the Silk Road and Viking contacts with Persia, however there is a chronological hole between the Viking period and Lapphyttan. Pig iron is an intermediate product and first product of Iron making reduced from Iron ore.

Its members account for more than 80% of production and international commerce in ore-primarily based metallics. Pig iron is the product of smelting iron ore with a high-carbon gas and reductant similar to coke, often with limestone as a flux.

The First Known Use Of Pig Iron Was

A manufacturing of pig iron has been carried out from crushing plant waste. The means of making ready pig iron was utilizing sizzling blast cupola furnace which was injected with charcoal powder to enhance temperature process and discount zone within the furnace. The process was began by washing course of and magnetic separation of uncooked material as an effort to improve iron content material diploma from crushing plant waste. The next course of was preparing the composite pellet with the particle dimension of −eighty+100 mesh and with the composition of eighty% iron ore, 15% wooden charcoal, and 5% bentonite. The experiment was continued to reduce pellet composite within the HBC furnace. The pig iron produced from this course of contained of ninety three.62%Fe, 3.5%C, 1.55%Si, 0.87%Mn, 0.05%P, and zero.087%S.With this outcome, the pig iron produced already fulfill the metallurgical specification for use in smelting industry.
