Cold ramming paste for integral furnace building of aluminum electrolysis cell and preparation method of cold ramming paste
The invention discloses a high-strength concrete which comprises aggregate, an adhesive and an additive material, the aggregate is a mixture of electrically calcined coal and graphite, and the use amount of the aggregate accounts for 80-84% of the mass of the cold ramming paste; the particle sizes of the aggregate include 3-5 mm, 1-3 mm, 0.074-1 mm and less than 0.074 mm, the content of the particle sizes with the particle sizes of 3-5 mm in the aggregate is 17.97-21.50%, and the content of the particle sizes with the particle sizes of 1-3 mm in the aggregate is 29.3-32.44%; the content of the particles with the particle size of 0.074 to 1 mm is 33.53 to 32.44 percent; the adhesive is one or more of spring oil, medium-temperature pitch and modified pitch; the additive material is one or more of resin and coal tar; the total amount of the adhesive and the additive material accounts for 16-20% of the mass of the cold ramming paste; the problem that a conventional cold ramming paste material cannot meet the overall furnace building requirement of the aluminum electrolysis cell is effectively solved.
本发明公开了它包括骨料、粘接剂和添加材料；骨料选用电煅煤和石墨的混合料，骨料用量占冷捣糊的质量比为80~84%；骨料的粒径包括3~5mm、1~3mm、0.074~1mm和小于0.074mm四种，其中骨料中3~5mm大小的粒径含量在17.97~21.50%，1~3mm大小的粒径含量在29.3‑32.44%；0.074~1mm大小的粒径含量在33.53‑32.44%；粘接剂使用蕙油、中温沥青和改质沥青中的一种或多种；添加材料使用树脂和煤焦油中的一种或多种；粘接剂和添加材料的总用量占冷捣糊的质量比为16~20%；本发明有效地解决了常规的冷捣糊材料无法满足铝电解槽整体筑炉需求的问题。
