本発明は表面処理鋼板、耐蝕性及び成形性を有する表面
処理鋼板の製造法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a surface-treated steel sheet and a method for producing a surface-treated steel sheet having corrosion resistance and formability.
従来、自動車用燃料容器（ガソリンタンク）としては、
Ｐｂ−８ｎ系合金を被覆せしめた所謂ターンシートが使

されている。Traditionally, automotive fuel containers (gasoline tanks) include:
So-called turnsheets coated with Pb-8n alloy are used, but recently in the market, methyl alcohol, ethyl alcohol, methyl tert-butyl is used for alcohol fuels such as methyl alcohol and ethyl alcohol, or for gasoline. Alcohol-laced fuels, such as alcohol (MTBA), have been used as an alternative fuel.
これらのアルコール燃料又はアルコール含有燃料には、

金属被覆層を有する耐蝕性表面鋼板が使用されている。These alcohol fuels or alcohol-containing fuels include:
Since corrosion resistance superior to that of conventional Pb-8n alloy plated steel sheets is required, Sn is added on one or both sides of the coating layer, which is mainly composed of a Pb and Sn alloy coating layer, on the surface of the steel plate.
A corrosion-resistant surface steel plate with a metal coating layer is used.
この鋼板上層のＳｎ金属層は電気メツキ方法で被覆する

キ法、溶融メッキ法はいずれも問題を有しており、この
欠点を解決する為の新規な製造方法が望まれている。Since the Sn metal layer on the steel plate is coated by electroplating, special plating equipment (electrolytic plating tank and plating power supply equipment) is required, and the equipment investment cost cannot be ignored. On the other hand, if the Sn plating layer is formed by a hot-dip plating method, the Pb gold metal of the lower Pb-Sn alloy coating layer tends to be dissolved in the Sn plating bath, making it impossible to obtain a Sn metal coating layer. Therefore, both the electroplating method and the hot-dip plating method for obtaining the steel sheet have problems, and a new manufacturing method is desired to solve these drawbacks.
また八〇又はＡｌ系合金メッキ鋼板は、耐蝕用の■型（

金メッキ浴に鋼板を浸漬して製造されている。In addition, 80 or Al-based alloy plated steel sheets are corrosion resistant ■ type (
There are two types: pure AI2 plated steel plate) and heat-resistant type (Al1-5i alloy plated steel plate).
It is manufactured by immersing a steel plate in a plating bath of Al or Al2 = Si-based alloy melted on a plating line.

鋼板の製造が望まれている。However, although the ■ type has excellent corrosion resistance, it has poor heat resistance, and the I type does not have the same corrosion resistance as the ■ type. Therefore, there is a desire today to manufacture Al-based hot-dip plated steel sheets that have corrosion resistance, heat resistance, and workability.

Hot-dip plating in a 1L or Al-based alloy plating tank, and then
Surface treatment in which the plating thickness is adjusted by a gas wiping method in an unsolidified state, and then metal powder is sprayed and deposited on one side or surface along with a carrier gas in an unsolidified state, and then heated and melted if necessary. This is a method of manufacturing steel plates.

immersed in. The immersed steel plate (■) is placed in the hot-dip plating bath (■) by gluing the outer periphery of the zinc roll (■), changes its direction, and is led out of the plating bath (■). The Pb-3n hot-dip plating layer adhering to the steel plate (■) is kept in an unsolidified state in order to maintain the appropriate amount of adhesion, and after being adjusted by the jet of gas blown from the gas wiping nozzle (■), the plating layer is solidified. Before doing so, it passes between metal powder injection nozzles (3) and receives a spray of metal powder. Metal powder is adhered to the surface of the unsolidified plating layer,
During cooling, if the metal powder does not melt due to lack of latent heat and has an uneven surface, it is heated and melted by the heating device ■ to make the surface smooth, improve adhesion to the plating layer, and improve the pin strength. Provides superimposed effects such as hole reduction. The steel plate is
After that, it undergoes post-treatments such as chromate treatment and phosphate treatment to become a product. Metal powder injection is generally carried out using a gas mixture with a carrier gas (mixing device not shown). As the carrier gas, air, hydrogen, nitrogen,
A hydrogen-nitrogen mixed gas is preferred. The particle size of the metal powder used is from 1 to 100, considering the relationship between cooling effect and surface unevenness.
6 The coating thickness by metal powder injection is set based on the line speed and the metal powder injection density.

の未凝固状態の確保によって調整される。It is also conceivable to use a steel plate having a plating layer as a pretreatment layer below the hot-dip plating layer. The bath temperature of the pb-5n hot-dip plating tank is preferably around 350°C, but this depends on the line speed, the relative position to the gas wiping method, and the amount of Pb- and Sn hot-dip plating layers formed when passing between the metal powder injection nozzles. It is regulated by ensuring the coagulation state.

れる。The heating device after injecting the metal powder heats the surface of the steel plate to a temperature higher than the melting point of the injected metal in order to remelt Sn and the like on the surface of the steel plate. As described above, by carrying out this dipping process, a surface-treated steel sheet can be produced easily and inexpensively without requiring special electroplating equipment or large-scale equipment for the hot-dip plating process.
