Pig Iron Manufacturing Process - 911metallurgist

Mar 20, 2017 · Later, during the experiments on the production of pig iron in the electric furnace at Domnarfvet, Sweden, 280 tons of crude non containing from 0.95 to 3.09 per cent, carbon were produced. This showed the possibility of producing pig steel in an electric shaft furnace. Later at Trollhattan, Sweden, these results were confirmed in a larger furnace.

Pig Iron Production - Blast Furnace Route - Metallics

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.

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.

DRI production | International Iron Metallics Association

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
