Corundum pressure injection material
The invention discloses a corundum pressure injection material which is characterized by comprising 90-95 parts of aluminum oxide, 42-46 parts of silicon oxide, 5-8 parts of magnesium oxide, 20-22 parts of graphite, 8-12 parts of white corundum, 8-12 parts of boric acid, 2-6 parts of calcium oxide, 1-2 parts of 95% silica powder, 0.5-1 part of sodium tripolyphosphate and 0.5-1 part of sodium hexametaphosphate. The corundum pressure injection material is provided with 42-46 parts of silicon oxide, 5-8 parts of magnesium oxide and 20-22 parts of graphite, wherein the magnesium oxide is preparedby adding magnesium oxide to form magnesium aluminate spinel, so that the corundum pressure injection material has good plasticity and cohesiveness, is easy to extrude and fills air attack and cracks,by adding 8-12 parts of boric acid, 2-6 parts of calcium oxide, 1-2 parts of 95% silica powder, 0.5-1 part of sodium tripolyphosphate and 0.5-1 part of sodium hexametaphosphate into the corundum pressure injection material, the corundum pressure injection material has the advantages of favorable sinterability, high strength, favorable erosion resistance, favorable erosion resistance, favorable high-temperature mechanical properties, favorable slag corrosion resistance, higher solidification speed and shorter waiting time.
本发明公开了一种刚玉质压注料，其特征在于：包括：氧化铝90‑95份，氧化硅42‑46份，氧化镁5‑8份，石墨20‑22份，白刚玉8‑12份，硼酸8‑12份，氧化钙2‑6份，95％的硅微粉1‑2份，三聚磷酸钠0.5‑1份，六偏磷酸钠0.5‑1份。本发明所述的一种刚玉质压注料，设有氧化硅42‑46份，氧化镁5‑8份，石墨20‑22份，通过加入的氧化镁制成氧化镁形成镁铝尖晶石，因此具有良好可塑性和黏结性好、容易挤出并填满空袭和裂纹，加入硼酸8‑12份，氧化钙2‑6份，95％的硅微粉1‑2份，三聚磷酸钠0.5‑1份，六偏磷酸钠0.5‑1份，使得刚玉质压注料烧结性好，强度高，耐侵蚀和抗冲刷性好，具有良好的高温机械性能及抗渣蚀性能，使得刚玉质压注料凝固比较迅速，等待时间较短。
