Magnesia Iron Spinel Brick For Cement Rotary Kiln Furnace
Introduction of magnesia iron spinel brick
Magnesia iron spinel bricks are a type of refractory material commonly used in high-temperature industrial applications. They are made from a combination of magnesia and iron oxide, which forms a unique crystal structure known as spinel. This composition provides the bricks with excellent thermal, chemical, and mechanical properties, making them suitable for various industrial processes.
Features of Magnesia iron spinel brick
Magnesia-iron spinel bricks have high thermomechanical properties and thermochemical properties in addition to the excellent kiln skin properties of magnesia-chrome bricks
