（従来の技術）
周知の通りほうろう成品の欠陥には、爪飛び、泡及び密
着性不良等があり、はうろう用鋼板と釉薬の組合せや前
処理が不適当な場合に、欠陥が発生しやすい。(Prior art) As is well known, defects in enamel products include nail skipping, bubbles, and poor adhesion, and defects occur when the combination or pretreatment of the steel plate for enamel and glaze is inappropriate. Cheap.

考えられる。Nail skipping occurs when hydrogen generated from the decomposition of moisture in the enamel glaze or the atmosphere of the firing furnace enters the steel during firing, collects at the interface between the steel plate and the enamel film during cooling, and the pressure of the hydrogen gas causes the enamel glands to form. It is thought that it was caused by being blown away.

等がある。On the other hand, foam-based defects include cockroach heads, pinholes, etc., and these are thought to be caused mainly by (C) in steel, carbide, etc. decomposing during firing and turning into COx gas, resulting in foam-based defects. To prevent this, as a measure to improve workability, decarburization is carried out during bathing or firing.

供することにある。(Problems to be Solved by the Invention) The object of the present invention is to provide a coated copper plate for enameling that simultaneously prevents nail skipping and bubble defects that occur when enameled products are made.
（問題を解決するための手段）
不発明は上記鋼板を提供するために、はうろう釉薬層の
下層に油を付着せしめたことを特徴とするものである。(Means for Solving the Problems) In order to provide the above-mentioned steel plate, the invention is characterized in that oil is attached to the lower layer of the waxy glaze layer.

提供することにある。That is, a layer of rust preventive oil is applied on the surface of an enameled steel plate with a surface roughness Rmax of 7.2 to 5.5 μm.
An object of the present invention is to provide an enameled coated steel sheet having one side of 5.69/m" and having an enameled glaze layer on the layer.

考えられない製品である。Generally, steel plates for crawling are completely degreased and then pickled or N
It is common knowledge to glaze after i-plating and neutralization, and it is essential to completely degrease or close to it. It is a product that would not be considered by conventional common sense to cause oil to adhere to the surface of the product.
以下、本発明の詳細な説明する。The present invention will be explained in detail below.
さて、本発明の鋼板は、表面粗度を調整したほうろう用
鋼板と、その表面に（１）さび止め油及び釉薬層又は（
２）Ｎｉメッキ層、さび止め油及び釉薬層の三又は門構
成体からなる。Now, the steel plate of the present invention includes a steel plate for enameling with adjusted surface roughness, and (1) a rust-preventing oil and glaze layer or (
2) Consisting of three or more gate structures: Ni plating layer, anti-rust oil and glaze layer.

析出物、介在物及び転位等の欠陥を調整し、はうろう用
鋼板に適するものにする。First, as a steel sheet for rolling, steel is processed through composition adjustment and decarburization or denitrification treatment at the steelmaking and annealing stages, heating hot rolling finishing temperature, coiling temperature, cold rolling rate, annealing conditions, temper rolling, etc. Defects such as intermediate precipitates, inclusions, and dislocations are adjusted to make the steel plate suitable for use in crawlers.

面はうろう掛けの場合は、はうろうを掛ける面のみでよ
い。The surface roughness of these steel plates is Rmax 7.2.
Adjust to ~55 μm. Generally, methods for adjusting surface roughness include pickling, dull roll rolling, and polishing (grinder, pitcher, etc.).
This is done by paring, shot blasting, electrical discharge machining, etc.) and grinding. Here, the surface roughness Rrnax is expressed as the average value of Rmax in the L and C directions on the front and back surfaces of the steel plate. If one side is a wall hanging, only the side on which the wall is hung is sufficient.
表面粗度がＲｍａｘで７．２μｍ未満では、その上にさ

する。If the surface roughness Rmax is less than 7.2 μm, the thickness of the oil film over the entire surface of the steel plate tends to be uneven when anti-rust oil is applied thereon (and when a waxy glaze is applied and fired,
The surface tension of the molten glaze causes the glaze to shrink, leaving some parts of the steel plate with glaze attached and others with no glaze attached.

〜４．０μｍである。Also, during firing, the glaze tends to float due to oil decomposition gas. In order to have an anchoring effect of oil and glaze on the steel plate, a roughness of Rmax of 7.2 or more is required, while the number of peaks per inch, PPI is approximately 25 to 3.
00 peak/inch, the centerline average roughness Ra is approximately 06
~4.0 μm.

ト的に不利である。In order to achieve an Rmax of more than 55 μm, pickling takes a long time, and a large amount of smut (dirt) adheres to the surface of the steel sheet, which tends to cause bubble defects in the product. Setting the roughness to more than 55 μm is disadvantageous in terms of cost because the roughness adjustment of the roll surface is mm and the roll surface is subject to severe wear during use, requiring frequent roll replacement.

正な粗度はＲｍａｘ ７．２〜５５μｍとした。Furthermore, shot blasting is suitable for roughening the surface of a steel plate, but in order to achieve an Rmax of over 55 μm, the shot injection pressure must be extremely high, resulting in high costs in terms of equipment and power consumption. From the above, the appropriate roughness is Rmax of 7.2 to 55 μm.
次に、さび止め油として、ＪＩＳでＮＰ−０〜１１及び
ＮＰ１８〜２０の１５種類に整理され、これらの中には

。Next, rust preventive oils are classified into 15 types according to JIS, NP-0 to 11 and NP18 to 20, and among these, there are those that are usually called rust preventive oils, lubricating oils, machine oils, etc. Volatile rust inhibitors are also believed to be effective.

止できると考えられるその塗油量は０．２〜５．６ ？
／ｍ”片面が適正である。The action and effect of the oil coating of the present invention is that the oil decomposes and burns at a low temperature until the enamel glaze softens and melts at approximately 500 to 600 degrees Celsius when the temperature rises during firing, and the water and oxygen in the glaze are evaporated and removed. The amount of oil applied is thought to be 0.2 to 5.6 to reduce or prevent the above-mentioned nail flying and foaming.
/m” single side is appropriate.
塗油量が０．２ｒ／ｍ２片面未満では、塗油していない

なくなり、本発明の主効果である焼成時に油か燃焼して
、はうろう釉薬中の水分の乾燥又は酸素の追出しに不十
分で、塗油の効果がなくなるからである。If the amount of oil applied is less than 0.2r/m2 on one side, some areas may not be oiled, or the amount is too small and the steel plate is no different from a normal degreased steel plate. This is because it is insufficient to dry the moisture in the waxy glaze or drive out oxygen, and the effect of the oil coating is lost.

起り易（なり、又コスト高になる。Furthermore, if the amount of oil applied exceeds 5.69/m" on one side, a large amount of oil will be burned and decomposed gas will be generated during firing, and the waxy glaze will float off the steel plate, peeling off, or partially floating. The glaze tends to fade (and the cost is high).
なお、上記のさび止め油の内、引火点が９８℃以上のも

で使用するとよい。Note that among the above-mentioned rust preventive oils, it is desirable to use one with a flash point of 98° C. or higher. Oil with a flash point of less than 98°C is burned during firing, and decomposed gas is generated in large quantities in a short time at low temperatures, causing the unmelted enamel glaze layered on the top surface to float from the surface of the copper plate. It may peel off, so it is best to apply a small amount of oil or mix it with one that has a high flash point.
塗油は一般にスプレィ、ロールコータ−１浸漬、フロー

After application, use a roll to even out the amount of application.
また、少量で均一塗布する場合には、静電塗装で行う。When uniformly applying a small amount, electrostatic coating is used.

るが、特にほうろう膜の鋼板への密着性を向上する。Alternatively, the steel plate may be coated with oil after being plated with Ni. That is, after adjusting the roughness of the steel plate surface, after degreasing and pickling, it was immersed for about several minutes in a several percent NiSO4 water bath solution (pH 25 to 3.0) heated to about 70°C, and plated. After that, it is neutralized, dried, and the above-mentioned anti-rust oil is applied. N
The effect of i-plating is to prevent defects in enamel products, but it particularly improves the adhesion of the enamel film to the steel plate.

。Next, the oiled steel plate can be used as a flat plate, such as a white plate or ξ flannel, or it can be bent, pressed, bath welded, etc., and processed into molded products for each purpose. For pressed parts, etc., there is sufficient oil remaining in the roughness of the steel plate, and it is sufficient as it is.

。In this way, a wax glaze is applied to the oiled steel plate for enameling. The floating glaze is made by adding a flotation agent, a coloring agent, and water to a glass material (frit) that is melted, then rapidly cooled and crushed, and then finely ground to approximately 200 mesh (slip) using a ball mill, etc. These ingredients are It varies depending on the wax component or its use, and various additives may be added.
