Product Information

Electro-fused seawater Magnesium Oxide is using chemical methods to extract production from the sea after 1800 ℃ calcination of magnesite, contains SiO2 ratio less, has a very high heat strength and slag resistance ability, for powdery and granular products, used for stainless steel, mild steel and alloy steel smelting induction furnace, furnace building materials. The product is easy to operate, stable in quality, long in service life, and has better comprehensive performance than electro-fused magnesia lining.
General products contain more than 95% MgO, up to 99.5%, with a volume density of 3.30 ~ 3.45g/cm3.The production cost is higher than that of natural magnesia, and the impurity boron needs to be removed, otherwise its high temperature performance will be affected.Due to its high purity, high density and high temperature performance, magnesia is mainly used to produce high quality refractory products. The advantages of Marine magnesia are summarized as follows.
1. High purity, high density and large crystal, advanced production technology, extremely stable quality.
2, the iron content is only 0.10-0.20%, ensure high fire resistance, longer life of the furnace
3. Electro-fused seawater Magnesium Oxide has no sharp Angle, which eliminates stress concentration and greatly reduces the tendency of cracks.
At present, the penetration rate of Electro-fused seawater Magnesium Oxide in precision casting factory is the highest in the region. In addition, a considerable part of precision casting stainless steel enterprises are gradually realizing the advantages of Electro-fused seawater Magnesium Oxide. More and more factories begin to use Electro-fused seawater Magnesium Oxide knot-forming lining, and good results have been achieved.
