It acts as a Heat insulator. It prevents escape of heat, thus keeping the iron in molten state.
It also prevents fire inside the furnace.
NOT recommended. Calcium Silicate (CaSiO3) is a by-product of the Blast Furnace, where it is called 'Slag'. Blast furnaces operate at a temperature of about 1200 oC . I doubt very much you ever reach this temperature at home.
Slag is the waste which is skimmed off the top of the molten iron that comes out of the blast furnace. It is a mixture of calcium and magnesium compounds, plus other impurities such as iron oxide, but is mainly calcium silicate. The formula for calcium silicate is CaSiO3.
Calcium oxide is formed in a blast furnace as a byproduct of the smelting process when limestone, which contains calcium carbonate, is added to the furnace. The intense heat of the furnace decomposes the calcium carbonate into calcium oxide and carbon dioxide. The calcium oxide is then collected as a solid residue.
A blast furnace typically contains iron ore, coke (fuel derived from coal), and limestone. These materials are layered in the furnace and hot air is blown in at the bottom to create a chemical reaction that produces molten iron.
Blast furnace = Hochofen
A blast furnace is used to extract iron from its ore.
Its because air is forced into the furnace to increase temperature. Steve.
NO!!! You will probably not kill yourself, but you will probably have stomach ache. Calcium Silicate )CaSIO3) is a by-product of Blast Furnaces. Such is the tonnage of it from blast furnaces it is made into 'breeze blocks' for building, or used a a road surface.
Govăjdia Blast Furnace was created in 1810.
A blast furnace is a forge in which ore is smelted to meal, being intensified by a blast of hot air.
