Regenerated magnesium-aluminum-carbon tundish dry material and preparation method thereof
The invention belongs to the field of refractory materials. The invention provides a dry vibration material for a regenerated magnesium-aluminum-carbon tundish. The tundish dry vibration material is prepared from the following components in parts by weight: 30-70 parts of regenerated magnesia-alumina-carbon brick particles, 0-40 parts of fused magnesia particles or dead burnt magnesia particles, 10-30 parts of fused magnesia fine powder or dead burnt magnesia fine powder, 4-6 parts of a binding agent, 2-4 parts of an antioxidant and 1-2 parts of a burning promoter. The invention further provides a preparation method of the dry vibration material. The dry material provided by the invention is low in sintering degree and easy to turn over and disintegrate after being used, and the slag corrosion resistance of the material can be improved by introducing the graphite in the regenerated magnesia-alumina-carbon brick with the non-wet steel slag; the waste magnesia-alumina-carbon bricks are adopted as raw materials, environmental pollution is reduced, the cost of refractory materials and the steelmaking cost are reduced, a new way is provided for recycling of the waste magnesia-alumina-carbon bricks, and the method has important significance in energy conservation, consumption reduction and environmental protection.
本发明属于耐火材料领域。本发明提供了一种再生镁铝碳质中间包干式振动料，所述中间包干式振动料由包括如下重量份的成分制成：再生镁铝碳砖颗粒30~70份，电熔镁砂颗粒或重烧镁砂颗粒0~40份，电熔镁砂细粉或重烧镁砂细粉10~30份，结合剂4~6份，抗氧化剂2~4份和促烧剂1~2份。本发明进一步提供了所述干式振动料的制备方法。本发明提供的干式料烧结程度低，使用后易于翻包解体，引入钢渣不润湿的再生镁铝碳砖中的石墨能够提高材料的抗熔渣侵蚀性能；采用废弃镁铝碳砖为原料，减少了环境污染，降低了耐火材料的成本和炼钢成本，为废弃镁铝碳砖的再利用提出了一种新的途径，对于节能降耗、环境保护具有重要意义。
