Environment-friendly dry material for continuous casting tundish and preparation method thereof
The invention belongs to the technical field of refractory materials, and particularly relates to an environment-friendly dry material for a continuous casting tundish and a preparation method thereof. The dry material is characterized by comprising the following components in percentage by weight: 12%-16% of 5-3 mm waste magnesia-alumina-carbon particles, 32%-36% of 3-1 mm waste magnesia-alumina-carbon particles, 14%-22% of 1-0 mm waste magnesia-alumina-carbon particles, 5%-9% of 180-mesh waste prefabricated brick powder, 14%-18% of 240-mesh fused magnesite, 5%-10% of 1000-mesh active causticcalcined magnesite, 3.5%-5.5% of composite binder, and 0.5%-1% of a sintering agent. The dry material disclosed by the invention is put into a continuous casting tundish for use, can be used for morethan 60 furnaces, is used normally from the conditions of a permanent layer after use and the residual condition of a casting residual surface, is excellent in performance, and is easy to turn over;waste recycling is achieved, and the dry material has important significance in energy conservation, consumption reduction and environmental protection.
本发明属于耐火材料技术领域，具体涉及一种环境节约型连铸中间包用干式料及其制备方法，其特征在于，以重量百分含量表示，所述干式料包括：5～3mm的废镁铝碳颗粒12％～16％、3～1mm的废镁铝碳颗粒32％～36％、1～0mm的废镁铝碳颗粒14％～22％、180目的废预制砖粉5％～9％、240目的电熔镁砂14％～18％、1000目的活性轻烧镁砂5％～10％、复合结合剂3.5％～5.5％及烧结剂0.5％～1％；将本发明干式料投入连铸中间包内使用，可使用60炉以上，从用后永久层状况和铸余表面残存情况看使用正常，性能优异，也易于翻包；本发明还实现了废料循环利用，对于节能降耗、环境保护具有重要的意义。
