Environment-friendly tundish dry material and tundish working lining, and preparation methods thereof
The invention provides an environment-friendly tundish dry material and tundish working lining, and preparation methods thereof. The environment-friendly tundish dry material is prepared from the following raw materials in percentage by weight: 20 to 25% of quartz sand with a particle size of 3 to 5 mm, 30 to 35% of quartz sand with a particle size of 1 to 3 mm, 15 to 20% of quartz sand with a particle size of 0 to 1 mm, 18 to 24% of quartz sand with a particle size of 200 meshes and 4 to 7% of edible sugar. The tundish dry material disclosed by the invention is prepared by taking quartz ore as a raw material and edible sugar as a binding agent; the quartz ore is rich in resource in China and very convenient to obtain, and raw quartz ore can be directly used without high-temperature smelting, so the environment is protected, and energy is saved; meanwhile, the edible sugar is adopted as the binding agent, the edible sugar is a food-grade hot melting material and does not discharge harmful irritant gas or liquid, and therefore, the problem that tundish dry materials produce pollution in the prior art is effectively solved.
本发明提供一种环保型中间包干式料、中间包工作衬及其制备方法。所述环保型中间包干式料由以下重量百分比的原料组成：粒度为3‑5mm的石英砂20～25%、粒度为1‑3mm的石英砂30～35%、粒度为0‑1mm的石英砂15～20%、粒度为200目的石英砂18～24%、食用糖4～7%。本发明的中间包干式料以石英矿石为原材料且以食用糖为结合剂制备而成，石英矿石在我国资源丰富，非常便于取材，且原石英矿石可以直接使用，不需要高温冶炼，进而保护了环境，节省了能源；同时，结合剂采用食用糖，食用糖为食品级的热熔材料，其不排放任何有害刺激性气体，也不会有液体排出，从而有效解决了现有技术中的中间包干式料产生污染的问题。
