COREX anhydrous stemming and preparation method thereof
The invention belongs to the technical field of steelmaking, and relates to COREX anhydrous stemming and a preparation method thereof. The COREX anhydrous stemming is prepared from the following refractory raw materials in percentage by weight: 20-25% of fine corundum, 20-25% of coarse corundum, 15-20% of silicon carbide, 1-2% of high-temperature asphalt, 2-5% of tar, 5-10% of sericite, 13-20% ofcoke powder, 15-18% of clay and 2-5% of aluminum micropowder. The COREX anhydrous stemming has the characteristics of quick drying, good volume stability, good opening performance, resistance to scouring and erosion of high-temperature slag iron and the like.
本发明属于炼钢技术领域，涉及一种COREX无水炮泥及其制备方法，所述COREX无水炮泥是由下列重量配比的耐火原料制成的，细刚玉20‑25%、粗钢玉20‑25%、碳化硅15‑20%、高温沥青1‑2%、焦油2‑5%、绢云母5‑10%、焦粉13‑20%、粘土15‑18%和铝微粉2‑5%。本发明具有快干、体积稳定性好、开口性能好、耐高温渣铁的冲刷和侵蚀等特点。
