Introduction of magnesia iron spinel brick

Raw material: divalent iron-aluminum spinel (FeO·Al2O3) and high-purity magnesia

Background: Magnesia-iron spinel brick is a new type of chromium-free refractory for cement                                rotary kiln that was first developed in Europe in the late 1990s.

Why special: During the firing process, the firing temperature and firing atmosphere are strictly                              controlled to ensure the iron oxide in the brick is FeO.
                        In the process of using magnesium iron spinel brick, a layer of highly viscous                                   calcium-iron and calcium-iron-aluminum compound is formed on the hot surface                             of  the brick, which is easy to hang the kiln skin. 

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
