Electric furnaces are classified as arc furnaces or induction furnaces, according to the heating method. The arc furnace is used far more extensively for steelmaking because its capacity is large and production efficiency is high.
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.
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.
If the ratio of CaO/MgO is less than 1.39, it will be called magnesia dolomite refractory brick. In China, Chinese mainly use resin bonded dolomite brick and resin bonded magnesia dolomite brick for converter furnace . Some factories use light burning oil and oil fired magnesia dolomite fire brick in easily damaged part.

Dolomite Refractory Materials a coarsegrained powder from crushed dolomite that has been fired to a sintered state and articles from such a powder, predominantly with resinous binding (unfired and fired). The sintered dolomite powder is used for patching the fettlings of openhearth and electric steel furnaces, and the dolomite products (including slugs ...
Granulated blast furnace slag and vitrified pelletized blast furnace slag are also used in the manufacture of blended hydraulic cements (AASHTO M240). (3) When used in blended cements, granulated blast furnace slag or vitrified pelletized slag are milled to a fine particle size in accordance with AASHTO M302 requirements.
During the production of iron by blast furnace (BF) route, dolomite is added either in the process of sintering or as a direct feed in the blast furnace. Raw dolomite is normally used for this addition. Dolomite addition is made during ironmaking for obtaining desired percentage of MgO in the BF slag.

Dolomite - Dolomite - Uses: Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces. The use of dolostone as a flux has increased, especially since environmental contamination has become a widely heeded ...
Dolomite is used in iron and steel industry as refractory raw materials and a flux. The BIS (IS: 10346–1982) has prescribed following specifications of dolomite for use in the manufacture of refractory bricks, felting materials and for the blast furnace and sintering plants.

Lime is put to use in primary steelmaking and secondary refining processes. Electric Arc Furnace (EAF) and Basic Oxygen Furnaces (BOF, QBOP, KOBM): Quicklime (dolomitic and high calcium) is used by steelmakers as a flux agent to efficiently and effectively remove impurities such as phosphorus, silica and alumina from scrap melting in the EAF.
(1) Iron and Steel Industry: Dolomite is used in iron and steel industry as refractory raw material and as a flux. The ISI (Is 10346&1982) has prescribed the following specifications of dolomite for use in the manufacture of refractory bricks, fettling material and for the blast furnace and sintering plants.
Burnt Dolomite Bricks Components. Dolomite brick is a kind of refractory products that is made from calcined dolomite sand. Generally speaking, the content of the calcium oxide is more than 40%, and that of magnesium oxide is 35% above.
