In the method proposed in No. 13, in order to start the combustion of the self-combustible heating element, the igniting agent is fixed in contact with the self-combustible heating element, and the ignition agent is surely burned by the spark of the igniter. It is necessary to arrange the ignition agent widely in the range where the spark of the igniting stone spreads, and the area of the ignition agent required for combustion must be widened, and the ignition agent is used more than the amount of heat required for ignition of the self-combustion heating element I had to.

発熱体の反応は一般にはテルミット反応と呼ばれ急激に
発熱反応し、高温に達することが知られている。[Function] The reaction of a self-combustible heating element formed by mixing an oxide such as iron oxide powder or copper oxide powder with aluminum, silicon, silicon iron alloy powder or the like is generally called a thermite reaction, and a rapid exothermic reaction occurs. It is known to reach high temperatures.

を発生させる方法が取られる。Since the self-combustible heating element has such a high combustion start temperature, the method of starting combustion generally involves bringing a more highly ignitable material into contact with a part of the heat generator to easily ignite this material. Alternatively, a method of locally heating the reaction temperature of the self-burning heating element or higher to generate an exothermic reaction of the reaction main agent of the self-burning heating element is employed.

みることが出来た。Thermite reaction using aluminum powder is mainly used for welding and is mainly used for industrial purposes. If ignition is performed reliably, much attention should be paid to the characteristics and amount of the igniting agent. In many cases, if the ignition failed, the ignition agent could be tried again by contacting the igniting agent again.

Naturally, ignition reliability and cost are important points. It is required to heat a heating element with a small amount of an igniting agent to generate a desired amount of heat to heat a target object to be heated.

And these are covered with a cover 4.

剤９に確実に接触するように構成されている。The spark generated by the cover 4 is guided to the depression 5, and the depression 5 contains a mixed powder 9 of iron oxide and boron.
It is provided in a shape that can be filled with 2 g or more, and the spark is configured to surely contact the ignition agent 9.

Is fixed to a plate-like frame 6.

に燃焼させることが可能となる。The igniting agent 9 filled in the recess 5 of the self-combustible heating element ignition jig thus configured is brought into contact with the surface of the self-combustible heating element via the opening 7 of the frame 6 without any gap. With this configuration, the self-combustible heating element can be reliably burned.

レス成形した場合に比べロスが少ない。As a result, the self-combustible heating element can be sufficiently ignited and burned by filling the self-combustible heating element with a weight that generates heat capable of igniting and burning. Less loss compared.

よい。As a heat source for burning the igniting agent filled in the cover 4, a method of applying a voltage to a resistance wire such as Ni to glow red can also be used, and it is sufficient if the igniting agent is brought into contact with the glowing portion.

が着火不能になる確率はより少なくなる。Further, when the cavities 5 of the cover 4 are filled with the igniting agent 9 in a powder state, the igniting agent falls off from the opening 7 of the frame 6 to which the cover 4 is fixed, and the self-combustible heating element is removed. There is a possibility that a sufficient amount of heat may not be obtained to reliably ignite. In order to ignite more reliably, the igniting agent 9 is mixed with a liquid such as alcohol or water to be slurried and pushed into the recess 5 of the cover 4 for filling. After drying, the adhesive strength between the igniting agent 9 and the cover 4 is increased, and the probability that the igniting agent 9 falls off from the opening 7 of the frame 6 and the self-combustible heating element cannot be ignited is further reduced.
【００３２】また乾燥後に粉末の固着強度を増すような

る。Further, by blending a viscous binder that increases the fixing strength of the powder after drying with the slurry liquid, the strength after drying is further increased and the possibility of falling off is further reduced.

かかり着火剤の脱落はより少なくなる。Further, by making the recess 5 of the cover 4 in the igniting agent charged portion slightly larger than the opening 7 provided in the frame 6, the charged igniting agent 9 is caught by the frame, and the falling off of the igniting agent is further reduced.

た。When the size of the cross section of the recess 5 of the cover and the shape of the opening 7 of the cover fixing frame are the same, powder filling is performed by changing the structure in which the opening is slightly smaller than the recess.
Comparing the ease with which the igniting agent of slurry filling and binder addition and slurry filling from the cover frame falls out of the cover frame under any conditions, the case where the shape of the recess is larger than the shape of the frame is less likely to fall off. I understood.

図２に示した。As a guide of the dropping condition, the dropping of the igniting agent from the height of 100 mm onto the iron plate under the condition that 0.3 g of the igniting agent is filled with the cover facing upward and the opening of the frame facing downward until the igniting agent falls. The number of drops was measured. FIG. 2 shows the state of the dropout.

され、扱いが非常に容易になる。As is apparent from this figure, when the size of the opening and the size of the cross-sectional area of the hollow are the same, the powder igniting agent falls off once, and even when it is slurried, it falls off three times. When the powder is smaller than the recess size, the powder can withstand the impact three times, when it is slurried ten times, when the binder is added, it withstands more than 50 times. The igniting agent does not fall off even if external force such as inversion, vibration, or impact is applied before the tool is set in contact with the self-combustion heating element, and the igniting agent is retained in the recess, making handling very easy.
【００３７】しかし外力を作用させない場合にはこの限

る。However, this is not the case when an external force is not applied. The recess and the opening have the same cross-sectional dimensions, and a powder-filled one can sufficiently achieve the purpose.
【００３８】特に乾燥状態の着火剤を充填する場合には
充填性を改善するためにペレット状、顆粒状にすること
も可能である。In particular, when the igniting agent is charged in a dry state, the igniting agent may be formed into pellets or granules in order to improve the filling property.
【００３９】バインダーを配合した場合はその配合率は

た。As a result, as shown in Table 1, when the weight of the igniting agent was 0.1 g, the heating element could not be ignited.
In the case of, the heating element can be ignited 6 times by 10 ignition operations,
With 0.3 g or more, all 10 ignitions were possible.

重量が発熱体を着火する限界であった。As a comparative example, when the exothermic raw material and the igniting agent are simultaneously press-molded, and when the igniting agent is simultaneously press-formed so as to come into contact with the exothermic raw material, sparks generated by igniter spatter and spread, and the igniting agent becomes large. Since the probability of receiving sparks in a concentrated manner is reduced, an area having a diameter of 20 mm is secured at the center of the heating element. As a result, the ignition agent weight of 1.0 g was at the limit of igniting the heating element.

火剤としては実用できないものであった。Table 2 shows the results. As a comparative example, a case of simultaneous press molding according to a conventional method is shown. As a result, even if the method according to the present invention uses relatively inexpensive industrial-grade iron oxide powder (used mainly as a ferrite raw material) for the iron oxide powder,
Even if iron ore having a low Fe 2 O 3 content of 97% was crushed to an average particle size of 1 μm and used, 100% ignition could be achieved. However, in the case of conventional press molding, 1.0 g of an igniting agent was used. However, since the ignition rate of the heating element does not reach 100% and is formed by pressing, even if the igniting agent portion comes into contact with the spark, it does not easily ignite, and the ignition operation needs to be performed 20 times or more. It could not be used as an ignition agent.
