The invention discloses a deoxidation slagging material and a preparation method thereof. The material comprises the following components in percentage by mass: 20-40% of aluminum powder, 20-40% of calcium oxide, 0.1-10% of boron carbide, 0.1-10% of calcium fluoride, 0.1-10% of sodium oxide and the balance of silicon dioxide. The preparation method of the material comprises the following steps: uniformly mixing and stirring calcium oxide powder and water to prepare calcium oxide slurry; adding the aluminum powder into the calcium oxide slurry, fully mixing and uniformly stirring, cooling, drying and crushing to obtain porous particles; and fully mixing the granular boron carbide, calcium fluoride and silicon dioxide, the porous particles and the sodium oxide to obtain a target product. The deoxidation slagging material is good in deoxidation effect, fast in slagging and easy to clean. 本发明公开了一种脱氧造渣材料及其制备方法，该材料中各成分的质量百分比为：20-40％的铝粉、20-40％的氧化钙、0.1-10％的碳化硼、0.1-10％的氟化钙、0.1-10％的氧化钠，余量为二氧化硅。该材料的制备方法为：将氧化钙粉与水混合搅拌均匀制成
