、かつ特殊な分り！ｔでの使用としかなりえなかった。Generally, in order to add corrosion resistance, weather resistance, chemical resistance, and design to a metal plate, it is known to form a coating film or an enamel coating layer on the surface of the metal plate. In particular, the enamel coating layer (hereinafter simply referred to as enamel) has the property of exhibiting the above-mentioned physical properties semi-permanently, except for impact resistance. Known base metal plates to which enameling is applied include steel plates, cast iron materials, stainless steel plates, aluminum plates, magnesium plates, and silver plates. However, if a bow is formed on a simple steel plate or cast iron material, and if a pin hole, armpit, or crack occurs in the bow, rust will form in the defective area, which will extremely contaminate the appearance and cause damage to the base metal. It had the disadvantage that it gradually eroded the board and corroded the entire $14 board. In addition, the glaze used to form the porcelain has a large surface tension, so it cannot sufficiently cover the sheared edges of the steel plate, etc., resulting in so-called non-porous areas. The problem was that moisture could seep in through the boundaries between the two, greatly reducing corrosion resistance. Furthermore, when enameling is applied to a stainless steel plate, although it is extremely unlikely to rust, it has the disadvantage of being more than twice as expensive as a simple steel plate. In addition, when enamel is formed on an aluminum plate, it lacks strength compared to each 1'4 plate, and is also quite expensive.
It had the disadvantage that the parts where it could be used were severely limited. Others, I
To form a glaze on J11 lead-plated steel sheets, since the melting point of zinc is approximately 420°C, there are almost no glazes that can be fired below this temperature for practical use, and even if they exist, they are expensive and require special techniques. ! It could only be used in t.

る。In order to eliminate such drawbacks, the present invention uses an aluminum-zinc alloy plated steel plate, which is about 10 times more corrosion resistant than this steel plate, instead of a galvanized steel plate that is inexpensive but has inferior properties, and uses the surface of the aluminum-zinc alloy plated steel plate. By forming a bow on this plating layer without destroying the aluminum-zinc alloy plating (hereinafter referred to simply as the plating layer), corrosion resistance, abrasion resistance, chemical resistance, and resistance to corrosion are improved. In addition to giving it a feminine, ceramic image, etc.
This invention proposes a steel plate coated with porcelain that is manufactured at low cost.

成を混合したような組成からなるものである。The aluminum-zinc alloy-plated steel sheet (hereinafter simply referred to as alloy-plated steel sheet), which serves as the base material in the present invention, is a steel sheet with a plating layer formed on its surface, and has the excellent corrosion resistance of aluminum. It is a copper plate that has the corrosion resistance of zinc and the sacrificial anticorrosive action, so-called galvanic action. To explain further, the plating II composition (weight ratio %) is
It is composed of approximately 4 to 95% aluminum, 5 to 95% zinc, and a trace amount of additives. The additives mentioned above include Sl, La, Ce, Mn, Sn, etc., and Si is mainly used to improve the workability of plating and the performance of plating. % (weight ratio) was added. Also, La, Ce,...
Mg and the like are added mainly to improve the fluidity of the plating bath, the wettability with the steel plate, the plating quality, and the amount of Mg added, for example, about 0.0% to the plating layer. 0
It is about 1 to 0.5%. In addition, in the present invention, porous glazes are porous glazes of various compositions (hereinafter simply referred to as glazes).
It becomes enameled when fired below the melting point of aluminum (660°C), and the thickness is 0.05 to 1.
It has about 5 fins and is formed by firing the glaze once or multiple times. Of course, when forming a bowl by firing multiple times, either the same glaze or different glazes may be used. More specifically, the glaze consists of a frit component, a mill additive, and water, and the additives include a floating agent, an emulsifying agent, a coloring agent, and a first coloring agent. 11〆d: For glazes with points in the range of 400 to 650℃, P

イメージの外観となし得る。Next, a method for producing an enameled steel plate according to the present invention will be explained. First, the thickness is Q, 5mm, and the plating layer is 25mm.
Prepare a μ alloy-plated steel plate, degrease its surface, and then thoroughly dry the surface. Next, the dried surface is glazed with a slip, for example, by applying a predetermined amount evenly with a spray gun, and drying at about 50 to 200'C for 10 to 30 minutes. This is to allow the water to evaporate gradually without causing the glaze to dry too quickly, making it difficult for cracks, pinholes, bubbles, etc. to form on the bowl. Next,
The applied glaze is heated to 650℃ or less, for example 400 to 650℃
It is baked in an electric furnace or the like for about 1 to 20 minutes to form a bow on its surface. The enameled steel plate manufactured in this way is made by molten all or part of the alloy plated steel plate. Since it is possible to form a bow on the surface which functions well as a plating layer even when coated, corrosion resistance, durability, abrasion resistance, and heat resistance can be significantly improved compared to galvanized steel sheets. Furthermore, since the bow is formed on the alloy plated steel plate, the appearance of the metal image can be changed to -Ji+S to give the appearance of a ceramic image.

What's more, the enamel does not suffer from cracking, cracking, pinballing, or peeling. In this case, the melting point of the plating layer is higher than the melting point of the glaze, whereas the suspension point of zinc in galvanized steel sheets is approximately 419°C. niZn
This is because it melts and has a great negative effect.

る特徴がある。As mentioned above, the enamel-coated steel sheet according to the present invention is
++ It has certain characteristics such as corrosion resistance, weather resistance, chemical resistance, and wear resistance that are 7 to 10 times higher than plated steel sheets. In addition, the enamel can be made into a porcelain enamel because it is heated to a considerably higher temperature than the heat resistant enamel, and the heat resistance of the enamel is around 650°C, so it can be used even in areas that require heat resistance while maintaining dimensional stability. Are there any benefits you can use? Furthermore, since the base metal of enamel is dimensionally and chemically stable at high temperatures, it is characterized by having almost no pinballs, cracks, cracks, wrinkles, bubbles, or cut surfaces. Furthermore, the alloy-mebuki copper plate has an enameled appearance, eliminating the metallic image, and is characterized by being able to be produced at low cost.
