摘要
再生鱼雷罐耐火材料可大量应用于铁水沟用ASC浇注料、铁水沟用ASC捣打料、铁水包包壁和包底用ASC不烧砖、沟盖浇注料等。但是有大量0.1~1 mm的再生鱼雷罐骨料因为粒度匹配原因未能有效利用。本文探讨了将不同比例的0.1~1 mm的再生鱼雷罐骨料加入到铁水包浇注料替代SiC,从而降低浇注料的成本,实现对再生鱼雷罐骨料的有效利用。试验结果表明,0.1~1 mm的再生鱼雷罐骨料加入量为9%时,制备的铁水包浇注料能满足铁水包浇注料的各项性能指标。在工业试验中,其强度低,更少粘渣,便于拆包修包,减少了工人的劳动强度。2022年在山西某厂15 t铁水包进行试用,其寿命比原铁水包浇注料提高15%以上,而浇注料吨成本降低约11%。
Recycled refractories for torpedo ladles can be widely used as ASC castables and ASC ramming materials for hot metal runners,ASC unburned bricks for hot metal ladle walls and bottoms,and castables for the runner covers.However,large quantities of recycled aggregates for torpedo ladles ranging from 0.1 to 1 mm are not effectively utilized due to particle size.This article explores the effective utilization of recycled torpedo ladle aggregates of 0.1~1 mm by adding different proportions into the ladle castables as a substitute for SiC,thus reducing the cost of castables.The experimental results show that when 9%of recycled torpedo ladle aggregate of 0.1~1 mm is added,the manufactured hot metal ladle castables can meet the various performance indicators.In industrial experiments,it features low strength and less slag adhesion,and makes the ladle easy to be debricked and repaired,reducing the labor intensity of workers.In 2022,a test was carried out on a 15-ton ladle at a plant in Shanxi province,and its service life was over 15%longer than the original ladle castables,while the cost per ton of castables was reduced by about 11%.
