Preparation method of spodumene-containing magnesium-chromium refractory material
The invention discloses a preparation method of a spodumene-containing magnesium-chromium refractory material, belonging to the technical field of refractory materials. The refractory material is composed of the following raw materials in percentage by weight: 15-25% of large magnesite particles, 15-20% of medium magnesite particles, 7-13% of small magnesite particles, 20-25% of fine magnesite powder, 4-6% of medium chromium concentrate particles, 4-6% of small chromium concentrate particles, 20-25% of fine chromium concentrate powder, 0.3-0.7% of fine spodumene concentrate powder and 3-7% ofa composite binder. According to the preparation method of the spodumene-containing magnesium-chromium refractory material in the invention, magnesia particles, chromium concentrate particles and finespodumene concentrate powder are used as raw materials to prepare uniformly-mixed mud; in the high-temperature sintering process of a green brick formed by pressing the uniformly mixed pug, the desired spodumene-containing magnesium-chromium refractory material is prepared; by reasonably matching the raw materials, the prepared spodumene-containing magnesium-chromium refractory material has goodfire resistance; and directed at the current situation of existing magnesium-chromium refractory material production processes, production cost can be reduced, and energy conservation and emission reduction are realized on the basis of ensuring various properties of the refractory material.
