Calcined Dolomite: A Strategic Solution in Refractory and Steel Industries
Calcined dolomite, which is the result of heating natural dolomite rock at very high temperatures (calcination), is a combination of calcium oxide (CaO\text< 3 >CaO) and magnesium oxide (MgO\text< 10 >MgO). Unlike ordinary lime, the presence of magnesium oxide in the structure of calcined dolomite gives it unique physical and chemical properties that make it an unrivaled choice in high-temperature industrial processes. By removing carbon dioxide from the initial structure, this material is transformed into a porous, reactive and highly stable product that plays a vital role in improving the quality of melting and increasing the life of thermal equipment.
Why do large industries use calcined dolomite?
The most important advantage of calcined dolomite is its protective role in the steelmaking and metallurgical industries. Due to the presence of magnesium oxide, this material has a high power in slag saturation, which results in the prevention of corrosion of the refractory walls of the furnace. The use of calcined dolomite not only significantly reduces the costs of furnace maintenance, but also speeds up the process of removing impurities from the melt.
Some key applications:
- Steel industries: Protection of furnace refractory bricks (slag alkalization) and assistance in the melt purification process.
- Glass industries: As a lubricant and improver of the chemical resistance of glass.
- Treatment and environment: Neutralization of acids and removal of heavy metals from industrial wastewater.
- Refractory material production: The main raw material for making magnesite-dolomite refractory bricks.
