Energy-saving steel ladle working lining castable and preparation method thereof
The invention discloses an energy-saving type steel ladle working lining castable, and the castable is prepared through the following steps: taking 60-75 parts by mass of low-thermal-conductivity sintered corundum particles as aggregate and 8-15 parts by mass of low-thermal-conductivity sintered corundum fine powder, 2-8 parts by mass of fused magnesite fine powder, 8-15 parts by mass of alpha-Al2O3 micro powder and 3-7 parts by mass of pure calcium aluminate cement as matrix materials; uniformly premixing the matrix material, adding the matrix material into the aggregate, uniformly mixing, additionally adding water accounting for 3-6wt% of the raw materials, uniformly stirring, carrying out vibration molding, maintaining at room temperature for 12-24h, and finally carrying out heat preservation at 110-200 DEG C for 12-36h to prepare the energy-saving steel ladle working lining castable. The energy-saving steel ladle working lining castable prepared by the invention has the characteristics of low heat conductivity, good thermal shock resistance and long service life.
本发明公开了一种节能型钢包工作衬浇注料，以60‑75质量份的低导热烧结刚玉颗粒为骨料，以8‑15质量份的低导热烧结刚玉细粉、2‑8质量份的电熔镁砂细粉、8‑15质量份的α‑Al2O3微粉、3‑7质量份的纯铝酸钙水泥为基质料；先将所述基质料预混均匀，再加入所述骨料中，混合均匀，然后外加占所述原料3‑6wt％的水，搅拌均匀，振动成型，室温条件下养护12‑24h，最后在110‑200℃条件下保温12‑36h，制得节能型钢包工作衬浇注料。本发明所制备的节能型钢包工作衬浇注料具有热导率低、抗热震性能好和使用寿命长的特点。
