Ladle working lining castable, ladle working lining and preparation method of ladle working lining
The invention belongs to the technical field of iron and steel metallurgy foundry ladles, and discloses a foundry ladle working lining castable, a foundry ladle working lining and a preparation method of the foundry ladle working lining. The ladle working lining castable comprises a component A and a component B, the component A comprises the following raw materials in percentage by mass: 18-24% of chrome corundum aggregate with the particle size of 5-8 mm, 15-25% of chrome corundum aggregate with the particle size of 3-5 mm, 10-18% of high-alumina particles with the particle size of 1-3 mm, 12-16% of high-alumina particles with the particle size of less than or equal to 1 mm, 6-9% of silicon carbide with the particle size of 0.074-1 mm, 4-8% of silicon carbide with the particle size of less than or equal to 0.074 mm, 6-10% of brown aluminum oxide dust collection powder, 4-8% of alpha-Al2O3 micro powder, 2-4% of silica powder, 1-3% of an additive and 1-3% of ball pitch; the mass ratio of the component A to the component B is 100: (3.5-4.5). The novel ladle working lining castable is developed and used for preparing the ladle working lining, the problems of iron seepage and iron drilling of brick joints of a brick working lining are fundamentally solved, and the cycle service life of the ladle working lining is prolonged.
本发明属于钢铁冶金铁水包技术领域,公开了一种铁水包工作衬浇注料、铁水包工作衬及其制备方法。该铁水包工作衬浇注料包括组分A和组分B,组分A包括以下质量百分比的原料:粒径5~8mm的铬刚玉骨料18~24%、粒径3~5mm的铬刚玉骨料15~25%、粒径1~3mm的高铝质颗粒10~18%、粒径≤1mm的高铝质颗粒12~16%、粒径0.074~1mm的碳化硅6~9%、粒径≤0.074mm的碳化硅4~8%、棕刚玉收尘粉6~10%、α‑Al2O3微粉4~8%、硅微粉2~4%、添加剂1~3%、球沥青1~3%,组分B为改性硅溶胶,组分A与组分B的质量比为100:(3.5~4.5)。本发明通过开发新型的铁水包工作衬浇注料,用于制备铁水包工作衬,从根本上解决砖砌工作衬砖缝渗铁、钻铁的问题,提高铁水包工作衬循环服役寿命。
