Description
Magnesia chrome brick is a basic refractory brick made from magnesia and chrome oxide, with periclase and magnesia-chrome spinel as the main mineral phases. It provides high refractoriness, strong resistance to alkaline slag erosion, good thermal stability, and reliable high-temperature strength.
JHYRef magnesia chrome bricks are used in severe furnace lining areas exposed to high temperature, slag corrosion, chemical attack, and thermal load. Typical applications include AOD refining furnaces, RH degassing furnaces, VOD ladle linings, non-ferrous metal smelting furnaces, cement rotary kilns, electric furnaces, converters, steel ladles, and glass kiln regenerators.
Key Features
– High refractoriness and stable performance under high-temperature service conditions
– Strong resistance to alkaline slag erosion and chemical corrosion
– Good thermal stability for furnace zones with temperature fluctuation
– High-temperature mechanical strength for severe working linings
– Suitable for steelmaking, non-ferrous smelting, cement, and glass furnace applications
– Available in standard sizes and customized shapes according to furnace lining drawings
