| 摘要 |
The invention relates to refractory industry, and can be used in production of periclase-chromite-spinel heat-treated refractory. Refractory mass contains periclase and/or breakage of periclase articles, burnt magnesium oxide (caustic magnesite), chromite ore, sodium polyphosphate, technical lignosulfonate, breakage of periclase-chromite and/or chromite-periclase articles, technical alumina and/or corundum, and/or tabular alumina. The proposed mass provides energy- and resource saving technology for the production of refractory by means of heat-treatment temperature of 185-230 ºC instead of 1750-1780 ºC, increasing of refractory resistance. |
