I am currently working on an assignment and I came across these questions that I am not clear of.1. Why is the temperature of the slag much lower than 1600 degrees?2. What process does the slag prevents from occuring in the iron? (sloag floats on it)3. Why might the furnace explode if wet substances were added?
In blast furnace the charge is held up by air: The charge is heated by a mixture of natural gas and coke mixed in witht the iron ore. . As the coke burns the ash filters down and falls to the bottom of the furnace. . The charge is a mixture of iron ore and coke {Purified coal} Low grade iron ore will have more impurities than high grade iron ore. This causes more slag Slag comes from the impurities mixed in with the iron ore when it is mined: It is less dense than iron and floats to the top of melt also reason it as hot as the iron since it is floating on top not in iron ore itself. . The rapid expansion of the water is what causes the explosion like reaction when water hits molten iron. .
