| titleOfInvention | A kind of unburned magnesia-chrome brick for metallurgy and non-ferrous smelting furnace and preparation method thereof |
| abstract | The invention belongs to the technical field of high-grade refractory materials for metallurgy and non-ferrous smelting furnaces and its preparation, and in particular relates to an unburned magnesia-chrome brick for metallurgical and non-ferrous smelting furnaces. A non-burning magnesia-chrome brick for metallurgical and non-ferrous smelting furnaces, comprising aggregate, powder and binder, the raw materials of the aggregate are composed of the following parts by weight: high-purity magnesia (MgO≥97.5%, particle size 7- 90 mesh) 35-45 parts, fused magnesia-chromium sand (MgO≥69%, Cr 2 O 3 ≥20%, particle size 7-90 mesh) 15-25 parts; the raw materials of the powder are composed of the following parts by weight : chromite concentrate (Cr 2 O 3 content is 47%-60%, Fe 2 O 3 content is 15%-27%, MgO content is 9.0%-13%, particle size is 300-350 mesh) 30-35 parts, Cold sintering agent (particle size nanoscale) 2-4 parts, rare earth oxides (particle size 2000-3500 mesh) 0.3-0.6 parts, activated alumina micropowder (particle size 2000-3500 mesh) 2-4 parts; binder 2-5 parts , 1-3 parts of water. The invention has the advantages of high purity, high density, high strength, good thermal shock stability at high temperature, strong corrosion resistance, strong resistance to molten metal and oxidation, no need for high temperature firing, low cost, energy saving and emission reduction, safe preparation and the like. |
