waste slag from blast furnaces is used for road surfacing.
Quartzite is used in blast furnaces in steel making as a flux material. It helps to remove impurities and non-metallic elements from the iron ore, allowing for the production of pure molten iron. Quartzite also helps to maintain the appropriate chemical balance in the furnace during the steel making process.
Thermal energy I suppose, but in most cases it is used for electricity. The steel industry uses coal (or coke rather) in blast furnaces.
Steel makers typically use coke, a type of solid fuel derived from coal, in the steelmaking process. Coke is used in blast furnaces to provide the necessary heat and carbon for the reduction of iron ore into molten iron, which is then used to make steel. Additionally, natural gas and electricity are also used as alternative fuels in some steel production processes.
Two common contaminants found in water used to cool blast furnaces are iron and sulfur. Iron can accumulate in the water from the contact with the metal parts of the furnace, while sulfur can be present due to the combustion of sulfur-containing fuels used in the furnace operation.
The industrial 8 gauge was used to tap steel furnaces or clean out steel buckets or kilns.
ore and coke
One major use was for making steam to power steam engines. Coal was also baked in furnaces to make coke which was in turn used in blast furnaces to mak iron.
Coal is primarily used for electricity generation in power plants. It is also used in the steel-making process to create coke, which helps to fuel blast furnaces. Additionally, coal is used in some industrial processes and as a source of heat in residential and commercial settings.
Iron (Fe)
Coal is burned mostly in fireboxes in coal fired power plants. Coal is also sometimes burned in furnaces in industrial facilities that refine and process various metals. Coal is also roasted (heated without oxygen so that it does not burn) to produce coke, which is widely used in steel mills (mostly as a carbon source and fuel in blast furnaces).
The main products of a blast furnace are pig iron (used to make steel) and slag (a byproduct that is used in construction materials).
