When the tip portion of the lance pipe configured by is burned, unless the tip portion of the lance pipe is sufficiently heated (molten state), it does not easily ignite, and even if it ignites, misfire easily occurs. Therefore, for example, the tip portion of the lance pipe is ignited by melting it with an oxygen acetylene melting machine, or burns a combustion material such as wood, charcoal, coke, etc. A method of igniting is adopted.

う等の難点があった。However, in the above-mentioned means, the oxygen acetylene melting machine and its peripheral equipment are required, and there is a drawback that the ignition work becomes large. In addition, when burning wood, charcoal, coke, and other combustible materials, it is necessary to secure a place for burning them, and it takes a relatively long time to ignite the tip of the lance pipe. . In particular, in steelworks and steelworks, when piercing a nozzle such as a ladle, cleaning, or opening the spout of a cupola, the lance pipe whose tip is burned in advance is relatively high. I am trying to do the drilling work by applying it to the above-mentioned drilling location, but since the tip of the lance pipe is burning, it becomes a backlight condition and it is difficult to accurately apply it to the desired position. Also, it was difficult to apply the relatively heavy and long tip of the lance pipe to the perforated part located at a relatively high place, and this work required physical strength and skill, and there were problems such as misfire during movement. .

イプPとなる。In the lance pipe provided with the ignition material A for ignition according to claim 4, an ignition material interior space P3 is provided at the tip of the outer pipe P1 of the lance pipe P, and the ignition material interior space P3 is provided. 6 is filled, the ignition material 5 is arranged so as to penetrate the ignition material 6, and the combustion flame blow-out hole P4 is formed behind the ignition material interior space P3 of the outer pipe P1. The igniter material 5 can be easily burned, and the igniter material 6 can be reliably burned by the combustion of the igniter material 5.
Combustion of the ignition material 6 makes it possible to generate sufficient energy to heat and burn the lance pipe P, so that the lance pipe P can be reliably burned. Further, the lance pipe P provided with the combustion material A for ignition can be configured simply, small in size, and light in weight, is not bulky, is easy to handle, and is easy to use.

ようになる。In particular, since the combustion flame blow-out hole P4 is formed behind the ignition material interior space P3 of the outer pipe P1, oxygen is blown to the combustion portion of the ignition material 6 and the combustion flame is generated.
1 The base end of the lance pipe P slightly returns along the inner peripheral surface and is blown out from the combustion flame blowout hole P4 so that the tip portion of the lance pipe P can be heated and burned over a relatively wide range. The tip portion of the lance pipe P can be heated and burned very stably and efficiently.
Moreover, the combustion flame blowout hole P4 of the outer pipe P1 causes the jetted combustion flame of the oxygen and the ignition material 6 to smoothly move along the front surface inside the outer pipe P1 and blow out from the combustion flame blowout hole P4. .
