How is heavy burnt magnesia produced

Re-burned magnesia is one of the main products produced by magnesia manufacturers. There are many uses for re-burned magnesia, and the demand is relatively large. Therefore, the manufacturer that produces this product needs to ensure the quality of the product in order to ensure its use effect during use. Next, let's introduce to you the production process of reburned magnesia. 96 Fused Magnesia

The production process of dead-burned magnesia: dead-burned magnesia is mainly made of natural magnesite ore with 46% content and calcined in a high-temperature hard kiln.

Uses of dead-burned magnesia: dead-burned magnesia is mainly used to make magnesia bricks and raw materials for the production of unshaped refractories. The finished products are used in steelmaking, electric furnace bottoms and ramming furnaces.

Re-burned magnesia is mainly made of 46.5% magnesite ore, which is calcined in a high-temperature shaft kiln at 1500℃1-800℃. The color of the product is yellow-brown. The main components of the re-burned magnesia products are magnesium oxide, calcium oxide, silicon dioxide, ferric oxide, aluminum oxide, and caustic soda. The main content of magnesium oxide is 80%. , 82%, 85%, 88%, 90%, 91%, 92%, 93%, the content of calcium oxide in re-burned magnesia is about 2.5%, and the content of silica in re-burned magnesia is 3.5%- The content of iron trioxide in the re-burned magnesia is between 0.8%-1.5%, the content of aluminum oxide in the re-burned magnesia is about 1%, and the content of caustic soda in the re-burned magnesia is 1%. First, re-burned magnesia is mainly used in brick making and the main ideal raw material for the production of unshaped refractories. In addition, re-burned magnesia products can also be used in steelmaking, electric furnace bottoms and ramming furnace linings.

The main types of re-burned magnesia are 80%, 85, 87%, 90%, 91%, 92%, and 93%. The re-burned magnesia of these varieties is mainly selected from 46.5% or more magnesite. When the ore is calcined and heated to 1400-1800℃ in the sintering kiln, Mg(CO3) is completely decomposed to produce periclase, which becomes hard reddish brown reburned magnesium, which has high refractoriness. Reburned magnesia is mainly used for magnesia bricks, steelmaking, electric furnace bottom and ramming furnace lining.

After the introduction of the above article, everyone should have understood the production process of reburned magnesia.
