Rongsheng Refractories Group
Magnevo-yellow spinel brick is an excellent firing product in a cement furnace “Without chromium”. It has an excellent ability to suspend the furnace shell, good resistance to the thermal shock, resistance to erosion of cement clinker and low coefficient of thermal expansion. It has an excellent effect of use in the firing zone in the cement furnace.
Magnes and iron spinel brick ingredients
Magnesial yellow-sophipinel bricks use high purity and aluminum-yellow spinel as the main raw material, which are formed by dosing and high pressure. In the production process, it is necessary to strictly control the firing temperature and the firing time.
