する瞬間を称している。If the base metal adheres, various problems will occur, so pure oxygen (hereinafter referred to as O!) is poured into the pot pipe, and the heat of the oxidation reaction between 02 and the steel pipe is used to remove the deposited base metal. A method of melting and removing (hereinafter referred to as oxygen cutting) is commonly used. During the oxygen cutting, ignition is first performed at the tip of the copper pipe. The ignition refers to the moment when the tip of the steel pipe itself melts and starts dripping.

でμ着火ができなくなる。Now, FIG. 1 shows an example of the oxygen cutting, and is a cross-sectional structural diagram of a molten steel ladle that stores and transports molten steel. After discharging the stored molten steel, the molten steel ladle 1 is turned over before receiving the next molten copper, and the base metal 3 adhering to the vicinity of the sliding nozzle device (hereinafter referred to as SN device) 2 is removed.

It is possible to ignite just by letting the water flow. However, for example, if the residual heat becomes low due to the time from when the molten copper is discharged until the time when it is heated for oxygen cutting, μ ignition cannot be performed only by NI storage.

It was customary to ignite the radish by forcing the four steel pipes into the radish and pouring it into the radish. In addition to admiring the time and effort required to obtain the hikari and set up the first stage of making hikari, the time required for making the first stage of moxibustion also caused many of the problems of temples where the quality of moxibustion was disappointing = Akira Honto 6 The main purpose of this is to fundamentally solve the conventional problems such as restraint.7 Now, the second

。In the experience of the present inventors, not only does the cutting powder (generally referred to as rag force) generated during nail manufacturing efficiently perform the above function, but also the cutting oil that adheres during nail manufacturing causes However, it was confirmed that easily oxidizable alloys and granular iron have extremely good ignitability when either or both of them are coated with oil. The attached table shows an example of experimental results based on the present invention. In this experimental example, a mixture 6 with various types and proportions of easily oxidizable alloy and granular iron was prepared, and about 150 (about 1!) of this mixture 6 was filled into a bag body 7 made of a plastic bag. An ignition envelope 8 was constructed.The ignition envelope 8 was then placed into the SN device 2 of the molten steel ladle 1 shown in FIG. 1, and the ignition situation by the steel pipe 4 was investigated.Ignition envelope 8 The residual heat in the SN device 2 into which No. 8 was introduced was in the range of 700-1200°C.As can be seen from the table, ignition was possible with sample Al using only the 0a-8i alloy, but it was strong. It was not practical because it emitted light and damaged nearby refractories.On the other hand, a mixture of easily oxidizable alloy and granular iron was used (Sample A2 to Sample Shop 6).
So, although there is a slight difference in the ignition time, practical ignition is possible, especially C! Sample &5, in which the a-8i alloy and whiskers were mixed at a weight ratio of 5:5, was 100% ignited within 5 seconds, and it was confirmed that the most efficient ignition could be performed.

よって前述の鋼管番の着火が可能となる。As shown in the table above, the present invention is a mixture of an easily oxidizable alloy and granular iron,
Alternatively, the ignition package 8 is constructed by filling a flammable bag 7 with a mixture of an easily oxidizable alloy and granular iron, in which one or both of them are coated with oil or fat. When oxygen cutting is performed, even if there is only a small amount of residual heat in the base metal adhesion part, the steel pipe 40 can be ignited in an extremely short time and easily by injecting 02 from the tip. The bag 7 may be made of, for example, vinyl, paper, cloth, rubber, etc., as long as it does not impede the combustibility of the mixture 6 and can hold the mixture 6 in a predetermined form. Bye. By the way, in all of the above embodiments, the ignition envelope 8 was described which can be applied to a part where the metal attachment part has a heat above a predetermined value (temperature above the ignition point of an easily oxidizable alloy). Connect the fuse 9 to the bag body 7,
By filling the mixture 6 into the bag 7, which is fully equipped with the fuse cord 9, to form the ignition package 80, it is possible to efficiently ignite even if the residual heat is below a predetermined value. . That is, the fuse cord 6 is ignited at about 240 to 420° C., for example, the fuse cord 9 is ignited by the slight residual heat of the part made of cotton, linen, straw, etc. to which the bare metal is attached, or by other heat sources such as a fire starter. After that, the bag and the mixture 6 are combusted through the fuse cord 9, thereby making it possible to ignite the above-mentioned steel pipe number.

ようになった。As described above, the ignition package 8 of the present invention allows the mixture 6 to be formed into any size and shape by the bag, and is extremely easy to handle. Even when removing bare metal from narrow areas such as 2 or the bottom of a deep pot that has residual heat that is difficult for workers to access, the steel pipe 4 can be easily ignited by simply inserting the ignition envelope 8 into the designated area. Therefore, oxygen cutting work can now be performed quickly and easily.
以上のように本発明の実用的効果は非常に大である。As described above, the practical effects of the present invention are very large.
