Magnesium-iron brick preparation raw material capable of increasing high temperature bending strength of magnesium-iron brick and magnesium-iron brick preparation process
The invention discloses a magnesium-iron brick preparation raw material capable of increasing the high temperature bending strength of a magnesium-iron brick and a magnesium-iron brick preparation process. The magnesium-iron brick preparation raw material contains magnesium-iron sand, wherein the magnesium-iron sand comprises the following components in percentage by mass: 20wt%-70wt% of MgO, 30wt%-80wt% of Fe2O3 and impurities which are less than or equal to 2wt%. The magnesium-iron brick and magnesium-iron brick preparation process comprises the following steps: (a) weighing each component in percentage by mass in the magnesium-iron brick preparation raw material; (2) adding materials with the particle sizes larger than 0.088mm into a mixing mill, mixing for 1-2 minutes, adding waste paper pulp, mixing for 3-4 minutes, adding materials with the particle sizes smaller than or equal to 0.088mm, and mixing for 3-4 minutes; and (3) weighing the mixed materials, adding the mixed materials into a mold, and producing the mixed materials into a brick blank by virtue of a friction pressure machine or a hydraulic pressure machine, and after drying at 110-120 DEG C for 24 hours, sintering at a high temperature of 1520-1610 DEG C, so as to obtain the magnesium-iron brick. According to the magnesium-iron brick preparation raw material, the high temperature bending strength of the magnesium-iron brick can be substantially improved, and the adverse effect caused by Al2O3 to a brick body can be greatly weakened.
