Abstract

The invention discloses a method for preparing ceramic fritted glaze from vanadium titano-magnetite tailings. The method comprises the following steps: weighing the vanadium titano-magnetite tailings,a correction raw material and a decolorizing agent according to a certain ratio, performing ball-milling, putting the materials into a natural gas furnace, performing high-temperature melting, putting the obtained glaze high-temperature liquid into frit cutting and quick-cooling equipment, quickly cooling the liquid to prepare blocks, and finally grinding the blocks in a vertical mill to obtain the ceramic fritted glaze. The method has the advantages of being high in component control precision and high in process stability and repeatability, and fine application and a high utilization rate of the vanadium titano-magnetite tailings can be achieved.

Description

technical field [0001] The invention relates to the technical field of glaze preparation, in particular to a method for preparing ceramic frit glaze from vanadium-titanium magnetite tailings. Background technique [0002] The composition of vanadium-titanium magnetite tailings is relatively complex, which makes it difficult to apply to fine materials, and the proportion of correction raw materials that need to be added during use is relatively high, which reduces its utilization rate. Therefore, it is very important to find a new method to improve the application value of vanadium-titanium magnetite tailings in the field of fine materials and to increase its utilization rate. [0003] Through high-temperature melting, melt cutting and quick cooling treatment and vertical grinding, fully improving the application value of vanadium-titanium magnetite tailings in the field of fine materials is a key means to improve its utilization rate.
