新日铁公司东京开发了一种热喷射耐火材料修补焦炉炉壁的方法。新法消除了沿用的湿喷(托克雷梯法)的所有缺点。现在这种拉瓦尔火焰系统的新方法已用在新日铁的大多数焦炉修复工作中,修复的部分寿命可延长5～10年。新方法将陶瓷粉变为熔液状,通过高温气体焰喷到待修补处。可以使炉壁接触缝处密合,充填已穿透的孔隙,并强化炉壁表面。喷 Nippon Steel Corporation Tokyo has developed a method of repairing coke oven walls by thermal jetting of refractory materials. The new law eliminates all the disadvantages of wet spray (Tocqueville). Now this new method of Laval flame system has been used in most of Nippon Steel coke oven repair work, the restoration of part of the life expectancy can be extended 5 to 10 years. The new method will ceramic powder into a melt-like, high temperature gas flame spray to be repaired. Can make the furnace wall contact seams close, filling has been through the pores, and strengthen the furnace wall surface. spray
