り、灯油の通り道を塞防いでしまうためである。Structure of conventional example and its problems Various press oils are used in the press working during the conventional manufacturing process of this type of oil tank, but most of them are degreased and removed in the subsequent degreasing process. That is, press oil contains glycerides such as glycerin monoester, siester, and triester as extreme pressure additives. Glycerides mix with kerosene and when burned in a kerosene stove, tar adheres to the wick, reducing fuel consumption. This is because the boiling point of glyceride is about 280℃ or higher, while kerosene has a boiling point of 150℃ or higher.
Because the temperature is 260℃, it does not evaporate from the wick, but accumulates inside the wick, reacts with oxygen coming from outside, and becomes tar through oxidative polymerization and condensation polymerization due to dehydrogenation, blocking the passage of kerosene. This is because it will disappear.

たものと同様長いものとすることができる。Effects of the Invention As can be seen from the above examples, according to the present invention, the press oil is not degreased before painting, so corrosion can be prevented without applying rust preventive oil. Since no coating work is required, costs can be significantly reduced. That is, oil tanks for kerosene stoves are manufactured with sufficient consideration given to corrosion resistance, since kerosene may leak out if holes are formed due to corrosion, which is dangerous. Generally, the inner surface of the tank is galvanized with a thickness of 30 g/m 2 or more for corrosion resistance, since water tends to accumulate at the bottom of the tank due to condensation of water vapor. However, if there is thick galvanizing, there will be welding defects (cracks, etc.) in the seam welding, and the outer surface may need to be painted to improve its appearance.
Like a thin galvanized 3g/ m2 or steel plate,
Use galvanized steel plate on one side. For this reason, if the water used during seam welding splashes on the outer surface, it will corrode, so conventionally, after press working, it was once degreased, coated with anti-rust oil, welded, and then left. This is because, unless degreased, conventional press oils will generate tar on the wick due to high boiling point substances such as glycerides. However, by using a press oil with low glyceride as in the present invention, tar generation on the wick becomes negligible, and as a result, there is no need to degrease the lamp wick until just before painting, and there is no need to apply a rust preventive agent. This allows for significant cost reductions. Furthermore, the lifespan of equipment such as kerosene heaters that use this oil tank can be made as long as those made using conventional methods.
