粘枪、烧枪是溅渣护炉中存在的主要问题之一。从溅渣技术和冶炼操作两方面进行分析,找到了影响粘枪、烧枪的主要影响因素。包况钢水出净与否,溅渣过程炉内气流状态,氧枪喷孔中心线夹角,枪位,枪冷却效果,造渣料加入时机,石灰质量,并提出些解决办法,有效缓解了溅渣护炉中粘枪、烧枪现象。 Stick gun, burning gun splash splashing is one of the main problems in the furnace. Slag splashing technology and smelting operation were analyzed from two aspects to find the main influencing factors of sticking gun and burning gun. The condition of molten steel in the bag or not, the state of air flow in the process of slag splashing, the angle between the center line of the lance spray hole, the position of the lance, the cooling effect of the gun, the timing of adding the slag, the quality of the lime and some solutions to effectively alleviate Slag splashing in the stick gun, burning gun phenomenon.
