Carbon-free steel ladle collector nozzle and preparation method thereof
The invention discloses a carbon-free steel ladle collector nozzle and a preparation method thereof, and belongs to the technical field of refractory materials, and the carbon-free steel ladle collector nozzle comprises the following components in percentage by weight: 60-64% of MAS-76 aluminum-magnesium spinel and 36-40% of co-grinding powder, totaling 100%; the co-grinding powder comprises 10%-18% of MAS-76 aluminum-magnesium spinel fine powder, 7%-13% of alpha-Al2O3 micro powder, 8%-10% of zirconite fine powder and 5% of metal silicon powder, and the thermosetting phenolic resin binding agent accounts for 4%-5% of the total weight of the co-grinding powder. According to the invention, MAS-76 aluminum-magnesium spinel is introduced as a granular aggregate, and through non-carbonization, the cleanliness quality of molten steel is improved, the product performance is improved, and the production cost is reduced; the carbon-free steel ladle collector nozzle has high temperature resistance, slag resistance and stripping resistance, and more MAS-76 aluminum-magnesium spinel particles and fine powder are distributed on the surface of the collector nozzle, so that the carbon-free steel ladle collector nozzle has good anti-scouring performance.
本发明公开了一种无碳钢包下水口及其制备方法，属于耐火材料技术领域，其组成成分及重量百分比为：MAS‑76铝镁尖晶石60％‑64％和共磨粉36％‑40％，总百分比为100％；外加占总重量百分比为4％～5％的热固酚醛树脂结合剂，其中共磨粉包括10％～18％MAS‑76铝镁尖晶石细粉、7％～13％α‑Al2O3微粉、8％～10％锆英石细粉和5％金属硅粉。本发明引入MAS‑76铝镁尖晶石作为颗粒骨料，通过无碳化，提高钢水洁净度质量，改善产品性能，降低生产成本；无碳钢包下水口具有耐高温性能、抗渣性能、抗剥落性能，且下水口表面分布有更多的MAS‑76铝镁尖晶石颗粒和细粉，具有很好的抗冲刷性能。
