How we make steel | British Steel

A hot air blast of temperatures around 1,000°C is injected at the bottom of the furnace through nozzles called tuyeres. As the coke burns, temperatures higher than 2,000°C are reached and this heat creates molten metal (iron). The molten metal collects at the bottom of the furnace and the limestone combines with impurities to form slag. Because this slag is less dense than molten metal, it ...

Blast furnace gas - Wikipedia

Blast furnace gas (BFG) is a by-product of blast furnaces that is generated when the iron ore is reduced with coke to metallic iron.It has a very low heating value, about 93 BTU/cubic foot (3.5 MJ/m 3), because it consists of about 60 percent nitrogen and 18-20% carbon dioxide, which are not flammable.The rest is mostly carbon monoxide, which has a fairly low heating value already and some .
