A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals,generally pig iron,but also others such as lead or copper.Blast refers to the combustion air being forced or supplied above atmospheric pressure.[1] In a blast furnace,fuel (coke),ores,and flux (limestone) are continuously supplied through the top of the furnace,while a hot blast of air blast furnace gas fired hot water boiler 20 tonblast furnace gas fired hot water boiler 20 ton.Blast furnace gas - Wikipedia Blast furnace gas (BFG) is a by-product of blast furnaces that is generated when the iron ore isWhat is Metallurgy? Metallurgy Definition History Metallurgical Coal.Metallurgical coal is an essential ingredient in blast-furnace steel production and accounts for around 70% of global steel output.Also known as coking coal,this carbon-rich form of coal is used to make coke which is the primary source of carbon used in steel-making.The coal is sourced through mining.Mineral Processing
