使用G01-100型割炬切割薄板(1.5毫米以下)时,最大的困难在于:预热火焰功率太大,使切口边缘熔比,熔渣粘附在背面难以剔除,钢板发生严重变形。曾试图以调小火焰方法解决,但还未及调到满意的程度火焰就熄灭了。国外为切割薄板,设计了单焰型、双焰型等形式的割嘴。特点是:预热 The biggest difficulty with the G01-100 cutting torch (less than 1.5mm) is that the preheated flame power is so great that the cut edge fusing ratio, clinker clinging to the back is hard to remove and the plate deforms severely. Attempts have been made to reduce the flame, but the flame is extinguished before it reaches a satisfactory level. Abroad for the cutting sheet, designed a single flame type, double flame type and other forms of cutting nozzle. Features are: Preheat
