Medium-frequency induction furnace ramming material and preparation method thereof
The invention belongs to the technical field of refractory materials, and particularly relates to a medium-frequency induction furnace ramming material and a preparation method thereof. The preparation method comprises the following steps: pretreating the magnesium aluminate spinel: mixing the magnesium aluminate spinel with a strong acid solution for reaction, filtering, washing and drying to obtain acid-leached magnesium aluminate spinel; roasting the obtained acid-leached magnesium aluminate spinel at the temperature of 180-200 DEG C for 3-5 hours, cooling and discharging to obtain pretreated magnesium aluminate spinel; mixing the raw materials: taking 100-120 parts by weight of pretreated magnesium aluminate spinel, 4-6 parts by weight of nano titanium dioxide and 10-15 parts by weight of a water-based adhesive solution, carrying out ball milling and uniform mixing, and pressing into a biscuit; and sintering: drying the biscuit, carrying out heat treatment at the temperature of 1500-1600 DEG C for 3-5 hours, cooling, and discharging to obtain the product. In the magnesium aluminate spinel pretreatment process, the particle size distribution range of the adopted magnesium aluminate spinel is 10-15 microns; and in addition, the D50 of the nano titanium dioxide is 10 to 30 nm.
