A furnace where a blast of air is used during the process to make iron

a furnace in which iron oxide is reduced to iron metal by using a very strong blast of hot air to produce carbon monoxide from coke, and then using this gas as a reducing agent for the iron

A towering cylinder lined with heat resistant (refractory) bricks, used by integrated steel works to smelt iron from iron ore. Its name is derived from the blast of hot air and gases forced up through the iron ore, coke and lime stone loaded in the furnace. Inside the blast furnace, the iron ore is chemically reduced to iron and physically converted (melted) to liquid iron. This is the iron making process. NatSteel Asia's steel factory produces steel from scrap and does not use blast furnaces.

A large cylindrical structure into which iron ore is combined with coke and limestone to produce molten iron. The mother of the steel industry furnaces, it creates combustion by forcing a current of air under pressure and obtains iron by the reduction of iron ore with suitable fuel and fluxes at high temperatures.

A furnace where mixed charges of oxide or sulfide ores (copper, iron, lead, tin, etc.), fluxes and fuels are blown with a continuous blast of hot air and sometimes oxygen-enriched air to force combustion for the chemical reduction of ores with metals to their metallic states.

A furnace in which solid fuel (coke) is burned with an air blast to smelt ore.

A furnace used for making iron

A blast furnace is a core facility for steelmaking that extracts high-purity steel from iron ore at high temperatures. The furnaces are usually around 100m high and the insides are lined with insulation bricks. In the refining process, hot air is blasted into iron ore and coke to melt them and remove oxygen. A comprehensive steel factory also processes crude steel made by the furnace into steel sheet and pipes and other products. Japan currently has 15 integrated steel factories. In China, Japanese steelmakers constructed and operated blast furnaces in Manchuria and other parts of China through the end of World War II to supply semi-finished steel products to Japan. Domestic production of crude steel reached 110.51 million metric tons in 2003, including output at electric furnaces, which use electricity to melt iron scraps and process them into steel.

A furnace used in the industrial smelting of iron from iron ore. Chemical equation : A system of writing down a chemical reaction, representing the reaction itself by an arrow, and showing the reactants on the left side of the arrow and the products on the right side.

A shaft furnace supplied with air blast, usually hot, for producing pig iron by smelting iron ore. The furnace is continuous in operation, the raw materials (iron ore, coke, and limestone) are charged at the top, and the molten pig iron and slag are collected at the bottom and are tapped out at intervals.

a furnace which uses blasts of air to intensify the smelting process

A cylinder-shaped furnace that produces pig iron or hot metal, which can be directly converted into steel.

where iron ore, coke and limestone are super-heated to create liquid iron

A vertical shaft furnace, equipped with a hot air blast, for producing pig iron from iron ore. The furnace is operated on a continuous basis.

A furnace for producing iron from haematite, fuelled by charcoal.

The blast furnace is a large structure approximately 30 metres high lined with firebricks which can withstand temperatures of 2000 degrees centigrade. The purpose of the furnace is to reduce iron ores into a liquid metal which can be tapped off and separated from the resulting slag. Such furnaces are normally heated by blasting pre-heated air to the base of the furnace through nozzles.

Facility for converting prepared iron ore into liquid iron (pig iron). It works on the counterflow principle: the charge (consisting of ore, burden, additives and coke) is introduced from the top – usually via a rotary chute. The hot blast flows in the opposite direction. The blast is pre-heated in stoves and injected into the furnace through tuyeres. Coke is used as reduction agent. Depending on charge and method of operation, different types of pig iron and even ferroalloys can be produced. A blast furnace remains in operation for many years (furnace campaign). The performance and cost efficiency of a blast furnace can be increased by larger furnace units, automatic charging, burden preparation, high blast temperatures, oxygen injection in the blast and pressurized charging. Blast furnace byproducts are blast furnace gas and blast furnace slag.

A furnace used in integrated steelmaking in which coke and iron ore react together under a hot air flow to form liquid hot metal, also called pig iron.

A cylinder lined with heat resistant bricks that steel mills use to smelt iron from ore. The name originates from the blast of hot air that is forced up through the ore.

introduced in the sixteenth century, a massively constructed retort in which iron ore, scrap iron, limestone and charcoal or coke were bellows blown to temperatures in excess of 1,100 degrees Celsius. Combustion was forced by a current of air under pressure; the resulting molten iron was tapped onto a sand floor, forming ‘pigs' of brittle cast iron.

A tower like furnace which uses a blast of air forced into the furnace from below to produce the intense heat needed to separate metals from the impurities in the ore.

A reaction vessel in which mixed charges of oxide ores, fluxes and fuels are blown with a continuous blast of hot air and oxygen-enriched air for the chemical reduction of metals to their metallic state.

Blast furnaces were used for smelting iron, and caused a major expansion in its production. Instead of using charcoal from trees, they used coke. Coke is coal which has been heated to burn off impurities, leaving carbon behind.

A tall (14-16 foot) hearth that reduces ore into slag and metal. Can achieve higher temperatures than the bloomery and can operate continuously with powered bellows.

A facility that coverts iron and other raw materials to hot metal (liquid iron at a very high temperature). A typical blast furnace is about 30 m high and produces 500 to 10000 tons of hot metal per day.

Closed-top-shaft furnace for producing pig iron from iron ore.

A furnace* in which a "blast" of air is forced through the fuel and the material to be heated, producing rapid combustion* and high heat. Usually employed for smelting* or other metallurgical operations. See also: air furnace*.

A tall, 60-70m high, refractory lined furnace of circular cross-section (diameter at the base - 12m) from the bottom of which liquid cast pig iron it tapped periodically. This is produced by feeding in a solid mixture of iron ore, limestone and coke at the top and by blowing in pre-heated air, and usually fuel, at the bottom.

A towering cylinder lined with heat-resistant (refractory) bricks, used by integrated steel mills to smelt iron from its ore. Its name comes from the "blast" of hot air and gases forced up through the iron ore, coke and limestone that load the furnace.

A blast furnace is a type of metallurgical furnace used for smelting. Fuel and ore are continuously supplied through the top of the furnace, while air (oxygen) is blown into the bottom of the chamber, so that the chemical reactions take place throughout the furnace as the material moves downward. The end products are usually molten metal and slag phases tapped from the bottom, and flue gases exiting from the top of the furnace.
