Ladle filler sand and preparing method and application thereof
The invention discloses ladle filler sand and a preparing method and application thereof, and belongs to the technical field of steelmaking auxiliaries. A raw material comprises 5 to 20 parts of zircon sand, 45 to 75 parts of chromite sand, 10 to 30 parts of quartz sand, 0.4 to 1 part of a carboloy lubricant and smaller than or equal to 4 parts of a sintering flux. The content of ZrO2 in the zircon sand is larger than or equal to 62wt%, at least 80wt% of grain size is 0.2 to 1 mm, the content of Cr2O3 in the chromite sand is larger than or equal to 46wt%, at least 85wt% of grain size is 0.25 to 0.9 mm, the content of SiO2 in the quartz sand is larger than or equal to 96wt% at least 85wt% of grain size is 0.4 to 0.85 mm, the ladle filler sand is uniform and stable in component, dense in filling, good in liquidity, uniform and moderate in sinter layer, and good in cast-on effect, the automatic cast-on rate is larger than or equal to 99.5%, and a preparing method comprises the step of baking a raw material mixed with water. The method is simple, easy to operate, suitable for industrial production, and suitable for preparing high-quality steel balls.
本发明公开了一种引流砂及其制备方法与应用，属于炼钢辅料技术领域。其原料包括5‑20份锆英砂、45‑75份铬砂、10‑30份石英砂、0.4‑1份碳质润滑剂及≤4份的烧结剂。锆英砂中ZrO的含量≥62wt％，至少80wt％的粒径为0.2‑1mm。铬砂中CrO的含量≥46wt％，至少85wt％的粒径为0.25‑0.9mm。石英砂中SiO的含量≥96wt％，至少85wt％的粒径为0.4‑0.85mm。该引流砂成分均匀稳定、填充密实、流动性好，烧结层均匀适中，开浇效果良好，自动开浇率≥99.5％。其制备方法包括烘烤与水混合后的原料，该方法简单，易操作，适于工业化生产。其适用于制备高品质钢种。
