Preparation process of electric furnace, steel ladle and converter steelmaking inner nozzle zirconia ceramic
The invention relates to a preparation process of an electric furnace, steel ladle and converter steelmaking inner nozzle zirconia ceramic, belongs to the technical field of preparation of zirconia ultra-high-temperature ceramic, and particularly relates to a preparation process of zirconia ultra-high-temperature ceramic with long service life for electric furnace steelmaking and steel ladle innernozzles. The process comprises the step of: preparing the following raw materials by mass: 2-4 parts of yttrium oxide, 0.5-8 parts of aluminum oxide, 65-95 parts of zirconium oxide and hafnium dioxide, 1-4 parts of cerium oxide, 2-3 parts of magnesium oxide, 3-4 parts of calcium carbonate, 1-3 parts of nano titanium oxide, 0.5-1.5 parts of anhydrous ethanol, 0.2-0.8 part of glycerol and 5-6 partsof water. According to the invention, the service life of a flowing channel in the flowing scouring process of molten steel can be prolonged, the performances of erosion resistance, scouring resistance and the like are improved, and the continuous service life of products in the links of electric furnace steelmaking, ladle inner nozzles, converter inner nozzles and the like is prolonged on the whole.
本发明为电炉钢包、钢包、转炉炼钢内水口氧化锆陶瓷的制备工艺,属于氧化锆超高温陶瓷的制备技术领域,尤其电炉炼钢、钢包内水口高寿命氧化锆超高温陶瓷的制备工艺,准备原料,包括以下质量份的原料:氧化钇2份~4份、三氧化二铝0.5份~8份、氧化锆+二氧化铪65份~95份、氧化铈1份~4份、氧化镁2份‑3份、碳酸钙3份‑4份、纳米氧化钛1份~3份、无水乙醇0.5份~1.5份、甘油0.2份~0.8份、水5份~6份;本发明可以增加钢液在流动冲刷的过程中对流动通道的寿命、抗侵蚀、抗冲刷等性能的提升,总体上提高电炉炼钢、钢包内水口、转炉内水口等环节产品的连续使用寿命。
