Upper nozzle brick for steel ladle and preparation method of upper nozzle brick
The invention discloses an upper nozzle brick for a steel ladle and a preparation method of the upper nozzle brick, and belongs to the field of refractory materials. The composite material comprises the following components in parts by mass: 1) 25-60 parts of granular aggregate which is composed of 15-35 parts of regenerated magnesium-chromium sand particles and 10-25 parts of regenerated magnesium aluminate spinel particles; 2) 19 to 35 parts by mass of co-grinding powder, wherein the co-grinding powder is prepared from 8 to 15 parts by mass of regenerated magnesium-chromium sand fine powder, 5 to 10 parts by mass of regenerated magnesium aluminate spinel fine powder and 6 to 10 parts by mass of alpha-Al2O3 micro powder; 3) 0.6 to 1.2 parts by mass of fiber, wherein the fiber is prepared from 0.5 to 1 part by mass of metal aluminum fiber and 0.1 to 0.2 part by mass of polypropylene explosion-proof fiber; and 4) a modified composite curing agent accounting for 4-6 wt% of the total weight of the granular aggregate, the co-ground powder and the fiber.
本发明公开了一种钢包用上水口砖及其制备方法，属于耐火材料领域。它包含：1)质量份数为25～60份的颗粒骨料，所述颗粒骨料由质量份数为15～35份的再生镁铬砂颗粒、质量份数为10～25份的再生镁铝尖晶石颗粒组成；2)质量份数为19～35份的共磨粉，所述共磨粉由质量份数为8～15份的再生镁铬砂细粉、质量份数为5～10份的再生镁铝尖晶石细粉、质量份数为6～10份的α‑Al2O3微粉组成；3)质量份数为0.6～1.2份的纤维，所述纤维由质量份数为0.5～1份的金属铝纤维、质量份数为0.1～0.2份聚丙烯防爆纤维组成；4)以及占颗粒骨料、共磨粉和纤维总重量4wt％～6wt％的改性复合固化剂。
