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。
