Magnesia calcium brick also called high calcium magnesium brick. In order to periclase as main crystal phase, silicate calcium for three secondary crystalline phase of magnesia
refractories. Containing MgO80% ~ 87%, CaO6% ~ 9%, CaO/SiO2 than in 2.2 ~ 3. The show structural characteristics of periclase and two calcium silicate calcium silicate and three direct contact, eutectic (interstitial 4CaO – Al2O3 – Fe2O3 into veinlets filled in the silicate calcium silicate calcium two and three between. Low porosity. Refractoriness under load was generally higher than 1700 DEG C, good performance of anti alkaline residue. But poor thermal shock resistance. Taking calcium magnesite as raw material, and through crushing, proportioning, mixing, molding, firing at 1550 to 1600 degrees. Can be used for side blown converter steelmaking at eye, open hearth and oxygen converter etc…

Magnesia calcium brick is basic refractory products with MgO and CaO as the main chemical components, including dolomite brick and magnesia dolomite brick. Magnesia calcium brick 
with excellent performance, especially with purifying molten steel performance is other kind of refractory materials do not possess. Therefore, magnesia calcium brick has been widely used in AOD furnace, VOD furnace and LF furnace refining equipment, and have achieved good results.
with excellent performance, especially with purifying molten steel performance is other kind of refractory materials do not possess. Therefore, magnesia calcium brick has been widely used in AOD furnace, VOD furnace and LF furnace refining equipment, and have achieved good results.
Magnesia calcium brick with seven properties, respectively, high temperature resistance, slag corrosion resistance, anti stripping performance, wear resistance, purifying molten properties, hydration resistance.
Along with our country stainless steel and all kinds of clean steel production capacity continues to expand, all kinds of refractories consumption will continue to increase. For better production and use of magnesia calcium brick, for China’s steel industry and other high temperature industrial services, to analyze and discuss the use performance of magnesia calcium brick, with understanding and knowledge of magnesia calcium brick using performance and influence factors is very necessary.
