Self-flowing tundish working lining dry material, tundish working lining and preparation method of tundish working lining
The invention provides a self-flowing tundish working lining dry material, a tundish working lining and a preparation method thereof, the self-flowing tundish working lining dry material comprises the following preparation raw materials by mass: 83-90 parts of fine powder with a particle size of 0.075-0.5 mm, 5 parts of fine powder with a particle size of less than 0.044 mm, 4-9 parts of a composite binder, and 1-3 parts of a sintering agent; wherein the fine powder is at least one of forsterite, magnesia-calcium sand, magnesia and quartz sand. The self-flowing tundish working lining dry material has the advantages of being low in volume density, low in heat conductivity coefficient, capable of achieving self-flowing forming, free of harmful and irritant gas, high in environment friendliness and the like.
本发明提供自流式中间包工作衬干式料、中间包工作衬及其制备方法，自流式中间包工作衬干式料，按照质量份数计算，其制备原料包括以下组分：粒度为0.075‑0.5mm的细粉83‑90份、粒度小于0.044mm的细粉5份、复合结合剂4‑9份、烧结剂1‑3份；其中，所述细粉为镁橄榄石、镁钙砂、镁砂、石英砂的至少一种。该自流式中间包工作衬干式料具有体积密度低，导热系数低，可自流成型，不产生有害刺激性气体，环保性强等优点。
