氧枪是转炉炼钢的重要设备，是向炉内供氧的主要工具，在转炉冶炼过程中，经常会出现氧枪粘钢的现象。对莱钢90 t顶底复吹转炉氧枪粘钢的原因进行了分析，从喷溅控制、枪位控制、炉渣碱度等方面查找原因，通过控制低温喷溅、高温喷溅，实施高-低-高-低枪位、低碱度冶炼等措施，达到全过程化渣；防止炉渣过泡或返干，保持炉渣碱度适中且流动性良好，保持稳定的炉底高度，及时测量液面高度并动态掌握枪位，从而减轻了氧枪粘钢，延长了氧枪使用寿命，提高了生产节奏。“,”Oxygen-lance-is-an-important-equipment-on-combined-blown-converter.It-is-common-that-during-the-smel-ting-process-in-converter,there-is-sticking-steel-on-the-oxygen-lance.The-main-factors-that-lead-to-sticking-steel-on-oxygen-lance-of-90t-combined-blown-converter-in-Laiwu-Steel-was-analyzed,searched-the-preventive-measures-from-oxygen-lance-position-control,slopping-control,basicity-of-slag,etc,Through-measures-such-as-controlling-the-splash-at-low-temperature-and-high-temperature,adopting-high-and-low-lance-position,and-low-basicity-refining,a-chieved-the-target-of-overall-process-slugging-and-prevented-the-slag-turning-excessively-wet-or-dry,made-the-slag-to-keep-a-proper-basicity-and-good-mobility.The-bottom-height-was-also-well-controlled;the-liquid-level-was-measured-in-time-to-obtain-the-lance-position.In-this-way,reduced-the-number-of-sticking-steel-on-oxygen-lance,increased-the-life-of-oxygen-lance,and-speeded-up-production-efficiency.
