为克服打水降料线停炉法炉内出现频繁爆震(气体的、水汽的)的缺陷,为实现安全、经济、快速停炉的总体目标,多年来太原钢铁公司高炉工作者摸索出一套行之有效的。“干式—正常负荷料—降压定风”停炉操作法。该法的要点是: ①喷水汽化。从煤气取样孔(或炉喉热电偶孔)插入4根顶端封闭的打水管至高炉中心。此管炉内部份断面上相隔30°角设三排孔径φ3mm、孔距为30mm的喷水孔,安装时喷孔向上。停炉过程中水压维持0.4MPa,控制阀门常开,开启度按需要调整、
In order to overcome the defects of frequent detonation (gas and water vapor) in the furnace shutdown method for lowering the water intake and discharge line, the blast furnace workers of Taiyuan Iron and Steel Company have worked hard for years to achieve the overall goal of safety, economy and rapid shutdown. Set of effective. “Dry - normal load material - step down wind” shutdown method. The main points of the law are: ① water vaporization. From the gas sampling hole (or throat thermocouple hole) into the top of the four closed drains to the blast furnace center. This pipe furnace section of the internal part of the angle of 30 ° set three rows of holes φ3mm, hole spacing of 30mm of the water hole, the installation of the nozzle up. During shutdown, the water pressure is maintained at 0.4MPa, the control valve is normally open and the opening degree is adjusted as needed.
