Product Introduction
Magnesia-Chrome Refractory Mortar is manufactured from magnesia fines, chromite powder, and high-temperature bonding agents. It is specifically designed for the laying and jointing of magnesia-chrome bricks, providing strong bonding and reliable sealing performance in high-temperature applications.The mortar features high refractoriness, excellent resistance to basic slag corrosion, and high bonding strength after firing. It forms dense and durable joints that effectively prevent the penetration of molten steel and slag, thereby enhancing the integrity and service life of refractory linings.It is widely used in the construction of RH vacuum degassing furnaces, electric arc furnaces (EAFs), cement rotary kilns, and other industrial furnaces lined with magnesia-chrome bricks.
