Metal-based functionalized stuffing sand and preparation method thereof
The invention relates to metal-based functionalized stuffing sand and a preparation method thereof, in particular to stuffing sand suitable for steel ladles in the high-temperature refining process. The stuffing sand is prepared from the following raw materials in percentage by weight: 35 to 50 weight percent of zircon sand, 15 to 25 weight percent of white corundum, 10 to 20 weight percent of high-alumina sand, 3 to 8 weight percent of forsterite, 1 to 3 weight percent of yttrium aluminum garnet, 0.5 to 1 weight percent of phosphorus lanthanum cerium stone, 0.5 to 1 weight percent of tantalum niobium iron ore and 0.1 to 1 weight percent of carbon black. By optimizing the raw material ratio and the preparation process, the ladle filler sand has excellent high temperature resistance, erosion resistance and thermal stability, and can effectively improve the automatic casting rate of a steel ladle after refining treatment such as VD (vacuum degassing) and the like, reduce energy consumption and ensure the quality of molten steel and safe and continuous production of a continuous casting process; the preparation method comprises the steps of raw material pretreatment, accurate proportioning, uniform mixing, granulation, drying, presintering, high-temperature sintering and the like, and high performance and consistency of the product are ensured.
本发明涉及一种金属基功能化引流砂及其制备方法，尤其适用于高温精炼过程中钢包的引流砂；所述引流砂由以下重量百分比的原料制成：锆英砂35‑50wt%，白刚玉15‑25wt%，高铝砂10‑20wt%，镁橄榄石3‑8wt%，钇铝石榴石1‑3wt%，磷镧铈石0.5‑1wt%，钽铌铁矿0.5‑1wt%，炭黑0.1‑1wt%；通过优化原料配比和制备工艺，该引流砂具有优异的耐高温性能、抗侵蚀性能和热稳定性，能够有效提高钢包在VD（真空脱气）等精炼处理后的自动开浇率，减少能耗，保证钢水质量及连铸工艺的安全连续生产；本发明的制备方法包括原料预处理、精确配料、均匀混合、造粒、干燥、预烧结和高温烧结等步骤，确保了产品的高性能和一致性。
