Welcome to know the introduction of magnesia-calcium bricks

Posted by annesheldon on January 23rd, 2017

The magnesia-calcium brick, also known as high calcium magnesite brick, is a kind of magnesial refractory material with periclase as principal crystalline phase and tricalcium silicate as secondary phase.It contains 80 % ~ 87% MgO, 6 % ~ 9% CaO, CaO/SiO2 ratio is between 2.2 ~ 3.0.Its significant structural feature is periclase directly contact with dicalcium silicate and tricalcium silicate,making eutectic solution-4 Cao Al2O3 Fe2O3 fill into crystal gap between dicalcium silicate and tricalcium silicate. Its porosity is low, the refractoriness under load is higher than 1700 ℃. It has good alkaline slag resistance ability, but with poor thermal shock resistance.There have many kinds of refractory products in our factory. Such as furnace drying tamp mass, fire brick, refractory nozzle, raw material. When you need any refractory products, welcome to view our website anytime. 

Made by calcium magnesia sand as refractory raw material, it will be made by firing at 1550~1600 ℃ after crushing, burdening, mixing and molding. It will be used at eye place of side-blown converter, top place of open-hearth furnace and oxygen-blown converter etc.

Magnesia-calcium brick has seven properties: High temperature resistance, slag resistance, spalling resistance, wear resistance, purifying molten steel and hydration resistance performance.

With the increasing production of stainless steel and all kinds of clean steel products, the demand of various magnesia calcium brick are increasing accordingly. For better production and using correctly, detailed understanding and learning of working performance and influencing factors of magnesia calcium bricks are very necessary.There have many kinds of refractory products in our factory, such as fire brick for sale, refractory nozzle, raw materials.
