Magnesia Ferrite spinel brick
Magnesium-iron spinel brick is a new chromium-free refractory for cement rotary kiln, which was first developed in Europe in the late 1990s. The product is mainly made of ferroalumina spinel (FeO. Al2O3) and high purity magnesia. In the process of firing, the firing temperature and atmosphere are strictly controlled to ensure the existence of iron oxides in brick in the form of FeO.
