The largest Blast Furnaces in the UK produce around 60 000 tonnes of iron per week The blast furnace at Redcar which is one of the largest in Europe has produced up to 11 000 tonnes per day 77 000 tonnes per week but is currently running at 8000 tonnes per day This is equivalent to all the iron needed for about 5 cars every minute Redcar number 1 blast furnace The hot air blast to the

The iron that comes straight out of the blast furnace is called pig iron and it tends to be very brittle because it contains 2 % 5 % carbon and other types of impurities Some of the pig iron is placed into molds to make what is known as cast iron Cast iron is primarily used to make pans drain covers engine blocks and fences The rest of the pig iron is usually turned into steel

27/7/2022 · 1 month ago II The blast furnace Iron is extracted from iron ore in a huge container called a blast furnace Iron ores such as haematite contain iron III oxide Fe 2O 3 In this reaction the iron III oxide is reduced to iron and the carbon is oxidised to carbon dioxide Like 0 Dislike 0 Reply Quote Follow

4/9/2022 · GENERAL OVERVIEW Iron is extracted through a method called reduction Raw materials used in the extraction of iron are Oxygen has to be removed from iron III oxide chemically to obtain iron Iron III oxide is reduced when oxygen is removed from it A blast furnace is used for this process [Figure 4]

the blast furnace from the top It is in the blast furnace that extraction of iron occurs The extraction of iron from its ore is a long and subdued process that helps in separating the useful components from the waste materials such as slag What happens in the Blast Furnace The purpose of a Blast Furnace is to reduce the concentrated ore

Due to the fact iron is not a reactive metal it can be extracted using an carbon in a blast furnace This is because iron is less reactive than carbon The iron is then displaced from the oxide by high temperatures and this is known as a displacement reaction Reduction of the ore A blast furnace is used for extracting iron It is an oven
