Describe How to Produce Pig Iron Using the Blast Furnace
The structure of a blast furnace. By using waste exhaust heat to preheat combustion air the amount of fuel to make a unit of pig iron was reduced at first by between one-third using coal or two-thirds using coke. Practical Maintenance Blog Archive Iron And Steel Known as reducing this can be done either in the blast furnace where hot air is injected into a continuous feed of coke sinter and lime or by the direct reduced iron DRI process. . In modern age the attempts are made to modify it or to adopt new methods of manufacturing pig-iron mainly for two reasons. Either way the fundamental activity in iron making involved a worker stirring small batches of pig iron and cinder until the iron separated from the slag. Bosh area of the furnace where the burden starts to soften and melt - direct. The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes. Hot air is forced through tuy...
