Tundish impact plate resistant to molten steel scouring and preparation method and construction method thereof
The invention relates to a tundish impact plate capable of resisting molten steel scouring as well as a preparation method and a construction method thereof. The invention belongs to the technical field of steelmaking. The tundish impact plate comprises, by weight, a main material and a binding agent, wherein the main material comprises the following raw materials in percentage by weight: 55-90% of tabular corundum, 0-28% of high-alumina bauxite clinker, 4-10% of ultrafine powder, 5-8% of a reinforcing agent and 0.5-1.5% of crystalline flake graphite; the dosage of the binding agent is 2.9-3.1% of that of the main material, the reinforcing agent is metal aluminum fine powder, and the tundish impact plate is obtained through mixing, mechanical pressing forming and heat treatment of the rawmaterials. The tundish impact plate has the advantages of higher breaking strength, higher compressive strength and lower linear change rate after burning, so that the tundish impact plate has good molten steel scouring resistance, and meanwhile, the tundish impact plate also has the advantages of simplicity and convenience in preparation and convenience in control.
本发明涉及一种抗钢水冲刷的中间包冲击板及其制备方法和施工方法，属于炼钢技术领域，按重量百分数计，中间包冲击板包括主料、结合剂，主料的原料包括板状刚玉55‑90%、高铝钒土熟料0‑28%、超细粉4‑10%、增强剂5‑8%、鳞片石墨0.5‑1.5%，结合剂的重量添加量为主料的2.9‑3.1%，增强剂为金属铝细粉，且原料经过混合，机压成型，热处理，得到中间包冲击板。该中间包冲击板，其具有较高的抗折强度，而且还具有较高抗压强度、较低烧后线变化率的优点，使中间包冲击板具有良好的抗钢水冲刷能力，同时还具有制备简便、便于控制的优点。
