A visual air-oxygen gun for blast furnace taphole consists of air-oxygen gun barrel. The outer end of the air-oxygen gun barrel is successively provided with a peeper mirror and a main ball valve. The peeper mirror is detachably connected with the air-oxygen gun barrel. The air intake pipe and the oxygen intake pipe are successively arranged near the outer end of the air-oxygen gun barrel body. The oxygen intake pipe ball valve is arranged on the oxygen intake pipe, and the air intake pipe ball valve is arranged on the air intake pipe. The utility model is equipped with a peep mirror at the end of the air-oxygen gun, through which the coke burning state in the hearth can be observed, and the oxygen quantity can be adjusted according to the flame color to ensure the safe use of the air-oxygen gun and the oxygen quantity needed in the hearth, thus avoiding the damage of the air-oxygen gun caused by improper oxygen control and prolonging the service life of the air-oxygen gun. When the blast furnace is opened, the peepscope is removed, the air intake pipe and oxygen pipe ball valve are closed, and the main valve is opened. The slag and iron flowing out from the hearth are flowed out along the air oxygen lance tube through the main ball valve. The direction of iron flow is determined, and the accident of iron running is avoided, so that the iron can be safely and smoothly discharged.

一种高炉铁口用可视化风氧枪
本技术涉及一种高炉使用的工具,特别是高炉铁口用可视化风氧枪。
技术介绍
高炉焖炉后的开炉是一项重要工程,高炉开炉过程的每个环节都需要技术人员和操作人员高度重视,严格按照规程操作,以保证高炉开炉圆满成功。随着高炉技术水平的提高,评价高炉开炉是否圆满成功的标准也在提高,除保证炉况顺行和能够安全顺利出铁以及快速达产之外,高效率和低消耗已经成为重要评价指标,也是业内人士追求的目标。近年来国家对环保的重视力度不断加大,根据空气质量,对钢铁企业要求限产或停产,经常会出现短期高炉停产。炼铁工序一般采取高炉焖炉的方式,限产结束,高炉进行焖炉后的开炉。开炉过程多数企业采用的是从铁口安装导风管,让炉内产生的煤气从铁口导风管排出,保证风口到铁口的透气性,喷吹的煤气,在导风管前端用明火点燃。这种方法会造成大量的煤气浪费,还会造成炉缸内大量的粉尘从导风管排出,污染出铁场环境;还有些企业采用的在铁口孔道内预埋高压风管,开炉后一直从高压风管向高炉炉缸内输送空气,该方式解决了采用导风管煤气、粉尘外溢的缺点,但是采取这种方式往往会出现开炉前几炉铁铁水物理热低,流动性差; ...
