A Process For Making Wrought Iron Direct From The Ore

Iron processing Britannica

Direct reduction, in which iron ores are reduced at temperatures below the metal’s melting point, had its origin in such experiments as the Wiberg-Soderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico in 1957. Few of these

How is Wrought Iron Made? - History of Steel - Carolina ...

Whether the iron ore was smelted in open hearths or in small or large blast furnaces, the product was wrought iron. Iron was produced by direct reduction of the iron oxide into iron metal. Despite the fact that iron has a melting point of 1540 degrees C, iron oxide can be reduced to metal at 800 degrees C.

Direct Iron Ore Smelting Process for Ironmaking – IspatGuru

28/03/2017  Direct iron ore smelting (DIOS) process is a smelting reduction process for the production of hot metal (liquid iron). It is a two-stage process which has been developed in Japan. It uses non-coking coal in a powder or granular form to smelt iron ore fines into liquid iron (hot metal) and hence, there is no necessity of a coke ovens plant and a sintering plant. The ore fines are pre-reduced in ...

Wrought Iron Production - WroughtWorks wrought Iron

The production of wrought iron or steel is a process containing two main stages. The first stage is to produce pig iron from iron ore in a blast furnace. Alternatively, it may be directly reduced. The second is to make wrought iron or steel from pig iron by puddling process a further process.Commercially available iron is classified based on purity and the abundance of additives. Pig iron

Wrought - process, iron, direct, fuel, furnace, hearth and ore

To-day wrought iron is nearly always obtained by treating pig or cast iron made in the blast-furnace, and the process is said to be 'in direct.' as compared with the 'direct' process of the ancients. The direct process is still em ployed by all savage races who make iron, and is also in use where the character of the ore. the fuel, or other conditions make the adoption of the blast

How iron is made - material, manufacture, making, history ...

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing

The iron separated from the surrounding rock without reaching a molten state. These ancient forges or bloomeries produced a spongy, crusty slag of iron. The impurities were squeezed out of the sponge iron by repeated heating and hammering to mix oxygen with the iron

History of Blacksmithing - Oldfield Forge

Blacksmithing origins first trace back to 1500 BC when the Hittites discovered the process of forging and tempering iron ore. When the Hittites were scattered in 1200 BC so was their knowledge and understanding of basic iron work. Launching into the Iron Age, a process to produce wrought iron was developed through reducing natural iron ore with heat. This new substance could be used to make ...

While the bloomery process produced wrought iron directly from ore, cast iron or pig iron were the starting materials used in the finery forge and puddling furnace. Pig iron and cast iron have high carbon content which make them very brittle, but they have a lower melting point than iron or steel. Cast and especially pig iron have excess slag which must be at least partially removed to produce ...

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 other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.
