Blast furnace metallurgy Britannica

Blast furnaces may have the following ancillary facilities: a stock house where the furnace burden is prepared prior to being elevated to the furnace top by skip cars or a belt conveyor system; a top-charging system consisting of a vertical set of double bells (cones) or rotating chutes to prevent the release of furnace gas during charging; stoves that utilize the furnace

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. 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 (sometimes with oxygenenrichment) is blown into the lower
