せる必要がある。However, at the time of applying the rust-preventive oil, which is a problem of the present invention, for example, in the case of a section steel such as an H-section steel, each section steel is combined to improve the transport efficiency. Due to the piling, if the amount of rust-preventive oil is large, oil accumulates between the flanges (especially, with water-soluble rust-preventive oil, the evaporation of water is slow and the paste hardens to cause poor degreasing). Therefore, it is necessary to form an oil film thinly and uniformly in a short time.

く、輸送中に油が落下する等の問題が生じる。[0008] Therefore, in view of these facts, in the above-mentioned conventional spraying method (1), there is no technical idea of accelerating the formation of the film of the adhered paint or uniformly applying the film.
Therefore, if the coating is not applied so that the coating is uniform, rust-preventive oil accumulates at the contacting parts of the product, which not only increases the cost, but also causes problems such as oil dropping during transportation.

の水溶性防錆油の塗付方法を提供することにある。The present invention has been made in view of the above-mentioned circumstances, and has as its object to reduce the time required for forming an oily film when applying a water-soluble rust-preventive oil to the surface of steel.
The oily coating can be applied uniformly, and the excess oil adhering to the surface of the steel material can be removed to achieve a uniform application state, and the excess oil can be collected and reused. An object of the present invention is to provide a method for applying rust preventive oil.

Shortens the time for forming an oily film.

【００２２】このような構成からなる塗付装置１を使用
して、本発明の水溶性防錆油の塗付方法を実施するに
は、次に述べるようにして行う。The method of applying the water-soluble rust-preventive oil of the present invention using the coating apparatus 1 having such a configuration is performed as follows.
【００２３】まず、水溶性防錆油スプレー前に、塗付し

油の水分を蒸発させる効果が小さい。また、50℃を越え
ると防錆油剤の損傷の恐れがあり防錆性能を悪化させる
ことから、設定されている。First, the temperature of the steel material 3 to be applied is raised to 30 to 50 ° C. in the preheating furnace 4 before spraying the water-soluble rust-preventive oil. When the temperature at the time of this temperature rise is 30 ° C. or less, the effect of evaporating the water content of the water-soluble rust preventive oil is small. Also, if the temperature exceeds 50 ° C., the rust preventive oil may be damaged, and the rust preventive performance is deteriorated.

きくなって回収効率が悪いことから、設定されている。Next, the preheated steel material 3 is sent to the spraying chamber 5, and when the steel material 3 is detected by a sensor (not shown), the steel material 3 is supplied to the steel material 3 from the nozzle 7 a of the spray gun 7 in the coating booth 8. Rust oil is sprayed at a pressure of 15 to 70 kg / cm 2 and applied. When the rust-preventive oil injection pressure is low, the mist diameter increases, and the cohesive effect generated when the rust-preventive oil collides with the steel material is small, and the rust-preventive oil flows without forming an oil film. Further, if the pressure is high, the mist diameter becomes too small, the scattering of the mist becomes large, and the collection efficiency is poor.

By using a pressure air of 3 kg / cm 2 or more, extra rust-preventive oil adhering to the surface of the steel material 3 is removed, and the state of application of the rust-preventive oil to the steel material surface is made uniform. The pressure of the compressed air at this time is set because if it is low, excess rust preventive oil cannot be uniformly removed.

連結して、１ケ所で行なっている。The excess oil that has been oversprayed is recovered by the recovery unit 7 and reused. The collection of the surplus oil is performed in one place by connecting the oil collection booth 11 including the application booth 8 and the oil removal booth 10.
【００２９】そして、このことから、この発明の塗付方
法による、水溶性防錆油の鋼材表面への均一な塗付が行

前述した実施例の予熱炉は、製造設備の乾燥炉等によっ
て兼ねることもできる。The coating method of the present invention can be applied to a water-soluble paint coating apparatus as it is. Also,
The preheating furnace of the above-described embodiment can also be used as a drying furnace of a manufacturing facility.

被膜，防錆被膜の形成が速い。Further, in the case of spray coating and oil coating, when the pressure is increased to a high pressure and expanded at the tip of the spray tip, the temperature rapidly drops, so that the evaporation of moisture is slowed down. The formation of the paint film and the rust-preventive film is fast because the temperature drop of the paint and the rust-preventive oil is compensated and the evaporation of the moisture can be further promoted.
【００３２】また、余剰防錆油を除去する油切りについ

ができる。The technical point of the water-soluble rust-preventive oil is how to reduce the evaporation of water which accounts for more than half (usually 70 to 95%) of the water-soluble rust-preventive oil. According to the coating method, the formation of the oily film of the rust preventive oil can be accelerated.
