空気鋳に逆火して爆発事故ノ界生ずる危険性があった。Traditionally, fusing and drilling of the workpiece have been performed using gas cutting, powder lances, and oxygen lances.
In the case of gas cutting, there are problems such as the cuts 1 to 1 are easily damaged by IB, and it is difficult to fuse the concrete 4M structure 1. In the case of powder lance, iron powder Since powder such as powder is continuously fed to the oxygen combustion part, there is a problem that some of the powder is scattered around unburned. There was a risk of backfire and an explosion.

さく溶断、穿孔作業の効率が悪くなる。In addition, those configured so that the lance is combusted and reacted with an appropriate flammable gas or the like have problems such as the risk of an explosion occurring if the lance misfires. Furthermore, in the case of thick workpieces such as concrete structures, the work position gradually moves to the back of the workpiece as the cutting and drilling operations are performed. Therefore, 1/i1″7 is constant for the blowing of molten particles.
ζ If there is, the blowing distance will be long, and the loss of 10 heat will cause the hole to melt and the efficiency of drilling work will deteriorate.
