喷补法是维修炼钢炉最常使用的方法之一。但还有许多缺点:如由灰尘引起的环境污染问题;因回弹引起的材料损失;喷补层结构松散且寿命低等。目前日本已研制成一种新型喷补系统—SNG系统(Shinagawa新型喷补系统),克服了上述缺点。新型喷补系统的粘合液由细粉末和粘合剂组成,它借助于泵的压力送到喷嘴处。喷补料通过空气送到喷嘴处,两者在喷嘴内混合之后进行喷补。 Spray repair is one of the most commonly used methods of repairing a steelmaking furnace. However, there are still many disadvantages: environmental problems such as dust; material loss due to springback; loosely packed layers with low life expectancy. At present, Japan has developed a new type of gunning system - SNG system (Shinagawa new gunning system), to overcome the above shortcomings. The adhesive system of the new injection system consists of a fine powder and a binder, which is delivered to the nozzle by means of the pressure of the pump. Spraying feed through the air to the nozzle, both in the nozzle after mixing gunning.
