Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, in a steel mill, cutting, drilling, opening, ladle, etc. in a furnace work before a steel melting furnace.
It is used when cleaning nozzles of electric furnaces, etc., or structures and other structures such as reinforced concrete, metal materials such as steel frames, refractories such as refractory bricks, rocks or structures in water, reefs Ignition method and for ignition of lance pipe designed to easily and surely ignite the tip of the lance pipe used when performing piercing, cutting, dismantling work, etc. while melting the workpiece to be melted The present invention relates to a lance pipe including a combustion material and a combustion material for ignition.

[0002]

2. Description of the Related Art Conventionally, an appropriate metal material (for example, steel pipe)
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.

[0003]

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. .
