A blast furnace is a common piece of equipment in the ironmaking process. The main raw materials for ironmaking include iron ore, coke, limestone, and air. During operation, iron ore, coke, and flux (limestone) are charged into the top of the furnace, while preheated air is blown in through tuyeres located around the lower part of the furnace. At high temperatures, the carbon in the coke (and in some furnaces, pulverized coal, heavy oil, natural gas, or other auxiliary fuels) reacts with the oxygen in the blown air to produce carbon monoxide and hydrogen, which, as they rise through the furnace, remove oxygen from the iron ore, thereby reducing it to metallic iron.
The components of a blast furnace system include: ① the furnace body; ② charging equipment; ③ blowing equipment; ④ injection equipment; ⑤ gas treatment equipment; and ⑥ slag and molten iron handling equipment.
