Ladle filler sand containing oxidizing agent and preparation method thereof
The invention provides stuffing sand containing an oxidizing agent and a preparation method of the stuffing sand, and belongs to the technical field of self-consumption cut-off devices. The filler sand containing the oxidizing agent is prepared from the following raw materials in parts by weight: 30-95 parts of chromium ore, 0-65 parts of quartz sand, 0-65 parts of fused magnesite, 1-4 parts of limestone, 1-2 parts of a carbonaceous material and 1-3 parts of the oxidizing agent. Wherein the sum of the parts by weight of the chromium ore, the quartz sand, the fused magnesite, the limestone, the carbonaceous material and the oxidizing agent is 100. According to the method, by means of the closed environment in a water gap after a steel ladle sliding plate is closed, under the high-temperature condition, the flow guiding sand is subjected to an oxidation-reduction reaction, series of phase change expansion is generated, fragile low-strength sintered blocks are generated, molten steel breaks through a sintered layer more easily under the same static pressure during casting, and automatic casting is achieved.
本发明提供了一种含氧化剂的引流砂及其制备方法，属于自耗截流装置技术领域。一种含氧化剂的引流砂，由如下重量份的原料制成：铬矿砂30‑95份、石英砂0‑65份、电熔镁砂0‑65份、石灰石1‑4份、碳质材料1‑2份、氧化剂1‑3份；其中，所述铬矿砂、石英砂、电熔镁砂、石灰石、碳质材料和氧化剂的重量份数合计为100份。本发明利用钢包滑板关闭后水口内的封闭环境，在高温条件下，使引流砂发生氧化还原反应，产生系列相变膨胀，生成易碎裂的低强度烧结块，开浇时使钢水在同等静压力下更容易冲破烧结层，实现自动开浇。
