Low-carbon converter tapping hole bushing brick
The invention discloses a low-carbon converter tapping hole bushing brick, which comprises the following components: fused macrocrystalline magnesia, fused magnesium aluminate spinel, graphite, alumina micro powder, metal aluminum powder, silicon powder, boron carbide, CarboresP carbon-containing resin powder, a binding agent and rare earth. The bushing brick provided by the invention has the advantages of high thermal shock resistance, high molten steel and slag scouring erosion resistance, high temperature resistance, lower apparent porosity and excellent oxidation resistance, greatly prolongs the service life of the steel tapping hole bushing brick, can meet the fast-paced production of a steel mill, guarantees the stable follow-up steelmaking rhythm, and improves the production efficiency.
本发明公开了一种低碳转炉出钢口套管砖，包括以下组分：电熔大结晶镁砂、电熔镁铝尖晶石、石墨、氧化铝微粉、金属铝粉、硅粉、碳化硼、CarboresP含碳树脂粉、结合剂、稀土。本发明提供的套管砖抗热冲击性、耐钢水和炉渣的冲刷侵蚀性强，耐高温，具有较低的显气孔率和优良的抗氧化性能，大幅提高了出钢口套管砖的寿命，能满足钢厂快节奏的生产，保障了后续炼钢节奏稳定，提升了生产效率。
