【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、金属板の表面処理方法に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for surface treatment of metal plates.

欠点をともなうものである。In such surface treatment of a metal plate, heating for alloying treatment takes time, productivity is poor, and heat-induced deterioration of the metal base material may occur. Also, depending on the application, the flatness of the alloy layer surface is insufficient. Furthermore, when simply layering powder on a metal plate, it is necessary to layer the powder relatively thickly (approximately 5001 Lm or more) in order to obtain a homogeneous coating layer, and in such a case, there are disadvantages such as high cost. It is something.
（課題を解決するための手段）

する、鋼板の表面処理方法である。(Means for Solving the Problems) The present invention is characterized by arranging metal powder on the surface of a steel plate, rubbing the metal powder into the steel surface with a roll to coat it,
This is a method for surface treatment of a steel plate, which is characterized in that the steel plate is then heated and then hot rolled.
（作 用）
本発明において、鋼板等の表面に配置する金属粉として

ウム、チタン、ステンレス等の１種又は２種以上の混合
金属粉あるいはセラミック微粒子を混合したもので、鋼

粉は、配置（積層）を容易にするため樹脂等のバインダ
ーを混入することもできる。(Function) In the present invention, the metal powder disposed on the surface of the steel plate, etc. may be, for example, one or more mixed metal powders such as zinc, tin, nickel-based self-fluxing alloys, aluminum, titanium, stainless steel, etc., or ceramic powder. It is a mixture of fine particles, and a material with a melting point equal to or lower than that of steel plate can be used. Such metal powder may also be mixed with a binder such as a resin in order to facilitate arrangement (lamination).
このような金属粉の粒径としては０．０１〜５００μが
適当である。５００μ超になると、後のロールによる鋼
板表面へのすり込み付着が困難になり取扱い上好ましく
ないこともある。The particle size of such metal powder is suitably 0.01 to 500μ. If it exceeds 500μ, it becomes difficult to rub and adhere to the surface of the steel plate using subsequent rolls, which may be unfavorable in terms of handling.
この金属粉の鋼板表面への配置は、すり込み層厚との関
係もあるが、例えば、すり込み層厚１．０〜１００ ｕ
であれば、ＩＯμ〜４．０ｍｍの層厚になるごとく、配
置するものである。The arrangement of this metal powder on the surface of the steel plate has a relationship with the thickness of the rubbed layer, but for example, the thickness of the rubbed layer is 1.0 to 100 u.
If so, the layers should be arranged to have a layer thickness of IOμ to 4.0 mm.
このようにして金属粉を鋼板表面に配置した後、ロール
（例えばセラミック系、ＮＩ系、ＣＯ茶系自溶合金又は
その複合材の溶射等が最適）で押え、鋼板の移動速度よ

逆方向に回転せしめ、金属粉を鋼板表面にすり込み付着
するものであり、ロールの押付力としては、例えば、前

速）の速度比としては、すり込み層厚は差速か大なる程
大きくなり、１：２〜１：５００（鋼板：ロール又はロ
ール二金属板）の範囲で十分である。After the metal powder is placed on the surface of the steel plate in this way, it is held down with a roll (for example, thermal spraying of ceramic, NI, CO brown self-fluxing alloys, or their composites is most suitable), and It is rotated at a low differential speed in the same direction or in the opposite direction to the 8th rotation direction of the steel plate, and the metal powder is rubbed and adhered to the steel plate surface. As for the thickness and the thickness of the rubbed layer, 0.1 to 5.0 kg/mm per roll unit length is sufficient. In addition, as mentioned above, the speed ratio of the steel plate moving speed and the roll rotation speed (peripheral speed) is 1:2 to 1:500 (steel plate: roll or roll two). (metal plate) is sufficient.
しかして、上記のごとき、ロールによる金属粉のすり込
みは、すり込み金属層厚を厚くして耐食性等をより向上
する場合は、複数回、金属粉配置〜ロールすり込みを繰
り返すものである。Therefore, in the above-mentioned rubbing of metal powder using a roll, if the thickness of the rubbed metal layer is to be increased to further improve corrosion resistance, etc., the process of disposing the metal powder and rubbing the metal powder with the roll is repeated multiple times.
このようにして鋼板表面に金属粉をロールにより、すり
込み被覆した後、加熱するものであるが、この加熱は、
後の熱間圧延のための加熱であり、例えば４００〜ｂ
熱を施し、次いで熱間圧延を行なうものである。After coating the steel plate surface with metal powder by rolling it in this way, it is heated.
This is heating for subsequent hot rolling, for example, heating to 400 to 100 lbs., followed by hot rolling.
熱間圧延としては用途により異なるが、圧下比２〜６倍
が適当である。For hot rolling, a reduction ratio of 2 to 6 times is appropriate, although it varies depending on the application.
このようにして表面処理した鋼板は、熱間圧延前におい
ても、通常のメツキ等により表面処理した鋼板に比べ耐
食性、耐摩耗性等が極めてよい、その理由としては、前
記のごとく、ロールにより、すり込んだ金属が強固に付
着するとともに熱間圧延により、すり込み金属が強固に
被覆でき、かつ鋼板の平坦度を向上できる。しかして、
このような鋼板は、例えば船舶の外板、海上油田構造物

うけ易いところ、あるいは建設機械用鋼板等、耐摩耗性
を必要とする用途に最適であり、鋼板厚としては、３〜
８０ｍｍが適当である。Even before hot rolling, the steel sheet surface-treated in this way has much better corrosion resistance and wear resistance than steel sheets surface-treated by ordinary plating, etc. The reason for this is that, as mentioned above, the rolls The rubbed metal adheres firmly, and hot rolling allows the rubbed metal to be firmly covered and improve the flatness of the steel plate. However,
Such steel plates require wear resistance, for example, for use in the outer panels of ships, marine structures such as offshore oil field structures, areas prone to corrosion and salt damage around bridges, or steel plates for construction machinery. It is most suitable for the purpose, and the steel plate thickness is 3~
80mm is appropriate.
