Large-size machine-pressed tundish impact plate and preparation method thereof
The invention discloses a large-size machine-pressed tundish impact plate and a preparation method thereof, and belongs to the technical field of steelmaking. The impact plate is prepared from main materials and a binding agent, wherein the main materials comprise 38-48 wt% of alumina particles, 10 wt% of fused magnesite particles, 18-28 wt% of tabular corundum particles, 16-18 wt% of white corundum fine powder, 3 wt% of crystalline flake graphite, 1-3 wt% of a reinforcing agent, 1 wt% of carbon-containing resin powder and 1 wt% of an antioxidant; the binding agent is composed of liquid phenolic resin and liquid methyl phenyl silicone resin in a weight ratio of 3: 2, and the weight addition amount of the binding agent is 2.5% of the weight of the main material. The preparation method comprises the steps of premixing, mulling, mechanical pressing and drying. The tundish impact plate provided by the invention has the advantages of high thermal breaking strength, high volume density, low porosity and the like, and has the advantages of small line after burning, good erosion resistance, good thermal shock resistance and long service life.
一种大尺寸机压中间包冲击板及其制备方法，属于炼钢技术领域。所述冲击板的制备原料包括主料和结合剂，所述主料包括：38～48wt%wt%矾土颗粒，10wt%电熔镁砂颗粒，18～28wt%板状刚玉颗粒，16～18wt%白刚玉细粉，3wt%鳞片石墨，1～3wt%增强剂，1wt%含碳树脂粉，1wt%抗氧化剂；所述结合剂为重量比例为3:2的液态酚醛树脂和液态甲基苯基硅树脂，结合剂的重量添加量为主料重量的2.5%。其制备方法包括预混合、混练、机压成型、干燥步骤。本发明中间包冲击板具有高热抗折强度，高体积密度，低气孔率等优点，且烧后线变小，抗侵蚀性能好，热震性能好，使用寿命高。
