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.

Production of Pig Iron by Using the Romelt Process

This is why Romelt is not only produce pig iron but also a power generator. The Romelt furnace works under negative pressure from 1 mm to 5 mm (water column) due to the presence of a pull fan. Figure 3 shows the diagram of the Romelt furnace. The Romelt furnace scheme:

Pig iron - blast furnace route | International Iron ...

Pig Iron Production - Blast Furnace Route. More than 1.1 billion tonnes of blast furnace iron was produced globally in 2016. Blast furnace economics are such that larger units have lower unit production costs, hence there has been a trend to bigger and bigger furnaces. Modern blast furnaces produce more than 10,000 tonnes per day.

Pig iron - Wikipedia

Pig iron, also known as crude iron, is an intermediate product of the iron industry in the production of steel 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.

Pig Iron Manufacturing Process - 911metallurgist.com

Pig Iron. In the electric-furnace production of pig steel from ore, carbon in the product can be kept below 2.2 per cent., and regulated to an extent by the amount of carbon charged, without resulting in excessive loss of iron in the slag or in the production of a pig steel very high in impurities, if a fair grade of ore is used. ...
