This process prepares it for the next stage which is the heating and forging to the desired wrought iron designs and shapes. This used to be an art of the blacksmith, but is now normally carried out by machines.

They all contribute to the smelting process. Hematite is a red ore and contains about 70% iron. Limonite is a hydrated oxide and contains about 60% iron. Magnetite is a magnetic oxide and contains about 72% iron. It takes about 1.6 tons of iron ore, 0.65 ton of coke, 0.2 ton of lime-stone and about 0.05 ton of scrap iron and steel to produce 1 ton of pig iron. For burning this charge, about 4

Pig Iron Manufacturing Process. Previous Next. View Larger Image; Table of Contents there is not so great an opportunity for the iron to come in contact with the coke as is the case in blast-furnace smelting when sponge iron is carburized at the tuyeres, so that a comparatively pure product settles out in the crucible of the electric furnace. Or, it is possible that, due to the fact that
Ferrous metallurgy Wikipedia
In the late 1850s, Henry Bessemer invented a new steelmaking process, that involved blowing air through molten pig iron to burn off carbon, and so to produce mild steel. This and other 19th-century and later steel making processes have displaced wrought iron.

Pig iron Wikipedia
In these processes, pig iron is melted and a strong current of air is directed over it while it is stirred or agitated. This causes the dissolved impurities (such as silicon) to be thoroughly oxidized. An intermediate product of puddling is known as refined pig iron, finers metal, or refined iron. Pig iron can also be used to produce gray iron.

How to Manufacture Pig Iron: How Pig Iron is made?
ADVERTISEMENTS: Guide for manufacturing and making Pig Iron. Following three distinct operations are involved in the manufacturing process of pig-iron: (1) Dressing ADVERTISEMENTS: (2) Calcination and roasting (3) Smelting. (1) Dressing: The iron ores as obtained from mines are crushed into pieces of size of 25 mm diameter. This is achieved in the rock crushers []
Smelting an overview | ScienceDirect Topics
The smelting process of this steel is to use the molten pig iron as the raw material without any fuel and to make steel with air being blown through the molten iron (the raw material) from the bottom or the sides of the converter, called pneumatic converter steel; if pure oxygen is used to replace the air, it is called the oxygen converter steel.
Blast furnace Wikipedia
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.

But process already beginning of amalgamating the more efficient local pig iron producers and eliminating the less efficient ones (in any case many will be ruined by winter frosts), C. Only a limited portion of the pig iron produced with such effort this 'fall will be made into steel. 1. Given the vissitudes of analyzing the pig, the steel pro- duced will vary widely in quality. 2.

Bloomery process | metallurgy | Britannica
Bloomery process, Process for iron smelting. In ancient times, smelting involved creating a bed of red-hot charcoal in a furnace to which iron ore mixed with more charcoal was added. The ore was chemically reduced (see oxidation-reduction), but, because primitive furnaces could not reach the melting temperature of iron, the product was a spongy mass of pasty globules of metal intermingled with

Changes to Iron Production | History of Western
It was a means of decarburizing pig iron by slow oxidation, with iron ore as the oxygen source, as the iron was manually stirred using a long rod. Puddling was done in a reverberatory furnace, allowing coal or coke to be used as fuel. The decarburized iron, having a higher melting point than cast iron, was raked into globs by the puddler.
