切割原理及其特点这种切割不用其它火焰,只用一根长铁管,在管中通氧,燃烧生成的氧化金属,从管子与坯料内空隙排出。用这种方法可穿孔(φ20～70毫米、孔深200～1000毫米的近似园孔,如配合 C 型切断器,可切割厚600～1000毫米之大料。切割前,用碳精片或气焊炬,局部予热管头及所需穿孔的坯料部分,予热至1000℃,将氧矛接触至被予热的毛坯,并打开气阀即可穿 Cutting principle and its characteristics This cutting without other flames, only a long iron pipe, the oxygen in the pipe, the combustion of the resulting oxidation of metal, the gap between the tube and the blank discharge. In this method can be perforated (φ20 ~ 70 mm, the hole depth of 200 ~ 1000 mm approximate Park hole, such as with the C-type cutter, can cut 600-1000 mm thick material. Cutting, carbon film or gas welding Torch, local to the hot pipe head and the required perforated blank part, to heat up to 1000 ℃, the oxygen lance exposure to be preheated blank, and open the valve to wear
