Basic Oxygen Furnaces vs. Electric Arc Furnaces

May 10, 2018A basic oxygen furnace is a pear-shaped structure with a closed bottom and an open top that works to process steel. Commonly known as BOF, this type of furnace relies on pure oxygen, rather than air, to convert iron into steel. Get price

Blast furnace for Sale

Blast furnace for rolling mill machine is of great importance in steel rolling process. Blast furnace smelting is the continuous production process of reducing iron ore into pig iron. Solid raw materials such as iron ore, coke and flux are fed into the blast furnace in batches by the top charging device and maintained at a certain height. Get price

Blast Furnace

Obtaining metals from their ores is a reduction process as the metal ion has to gain electrons. Ores of metals high in reactivity series are difficult to extract and electrolysis is used. Middle order metals like iron are extracted by reducing with carbon in the blast furnace. Blast Furnace: The main ore of Get price

Process

The main processing steps of the Base Metals Operations are the blast furnace, the lead refinery and the special metals plant. The blast furnace reduces the oxidized lead slag from the smelter together with high lead containing third party raw materials and transforms them into impure lead bullion, nickel speiss, copper matte and depleted slag.

Blast Furnace Stoves

Blast Furnace Stoves. Inspection Repair. The ceramic welding process utilizes a dry mixture of refractory powder and metallic fuels. This mixture is projected onto the area to be repaired using custom-made air and water cooled lances. Conveyed by a stream of oxygen, the mixture ignites on the hot repair surface in an exothermic reaction Get price

Coke (fuel)

These were the invention of the hot blast in iron-smelting and the introduction of the beehive coke oven. The use of a blast of hot air, instead of cold air, in the smelting furnace was first introduced by Neilson in Scotland in 1828. The hearth process of making coke from coal is a very lengthy process. [citation needed] Beehive coke oven Get price

Steel making today and tomorrow

In the current blast furnace based process, coal is the main source of energy. The use of coke ovens produces metallurgical coke and coke oven gas. The coke is used in the blast furnace process, and the coke oven gas is used as the major fuel in the whole steel mill. Get price

HOW A BLAST FURNACE WORKS

HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called hot metal. The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. Get price

Blast Furnace, Coke Gas and Converter Gas for Power Production

Blast furnace gas is a by-product of blast furnaces where iron ore is reduced with coke into metallic Within the blow moulding process, the pig iron is refined with oxygen or air, lowering the carbon proportion and providing enough process heat to maintain the steel liquid. With 60% of the worldwide raw steel production, the Linz-Donawitz Get price
