Magnesian furnace protection material and use method thereof
The invention discloses a magnesian furnace protection material and a use method thereof. The magnesian furnace protection material comprises the following raw material components in percentage by mass: 60-70% of tundish refractory, 20-30% of limestone and 3-5% of a silicon-calcium-based adhesive. In-plant cyclic utilization of the tundish refractory material is achieved, the tundish refractory material has high fire resistance and can bear thermal shock and chemical erosion in a high-temperature environment, the tundish refractory material is used as a magnesian furnace protection material, the fire resistance of the furnace lining can be effectively improved, the service life of the furnace lining is prolonged, and the final finished product is high in pelletizing rate, high in strength and good in performance. And the MgO content meets the use requirement of slag splashing furnace protection, the problems of resource waste and environmental pollution are greatly reduced, the smelting efficiency is improved, the energy consumption is reduced, and environmental protection and sustainable development are promoted.
本发明公开了一种镁质护炉料及其使用方法，所述镁质护炉料原料组分以质量百分比计包含：中间包耐材60％～70％，石灰石20％～30％和硅钙基粘接剂3％～5％。本发明中对中间包耐材实现了厂内循环利用，中间包耐材具有较高的耐火性能，能够承受高温环境下的热冲击和化学侵蚀，将其用作镁质护炉料，可以有效提高炉衬的耐火性能，延长炉衬的使用寿命，本发明的最终成品成球率高，强度高，不易碎裂，MgO含量达到溅渣护炉的使用要求，极大减少了资源浪费及环境污染问题，提高冶炼效率、降低能源消耗，并促进环保和可持续发展。
