Abstract

PURPOSE:To produce a stainless steel sheet which has tint color tone and luster and is excellent in the design effect by rolling the stainless steel sheet with a rolling roll having the fine unevennesses to roughen the surface and thereafter forming a chromic acid-based colored film and performing polishing of the specified degree. CONSTITUTION:A hot-rolled stainless steel sheet is pickled, cold-rolled, annealed and pickled. Thereafter it is rolled by a rolling roll having 10-25mum ten-point mean roughness (Rz) and the fine uneven parts 3, 4 having 1-12mum ten-point mean roughness (Rz) are formed on the surface of the stainless steel sheet. This stainless sheet 2 is treated by mixed acid of sulfuric acid and chromic acid or chromate to form a colored film 5. Thereafter hardening treatment due to cathodic electrolysis is performed by mixed acid of sulfuric acid or phosphoric acid and chromic acid. Successively the surface is polished and finished so that the ten-point roughness (Rz) is free from directional property and regulated to a range within 1-8mum. The designed steel sheet is obtained wherein the bare surfaces 6 of an original sheet are formed in the projecting parts 3 and the remaining colored films 5a are formed in the recessed parts 4.

[Industrial Field of Application] The present invention relates to a stainless steel plate with a light color tone and light luster and a high design effect, and a method for manufacturing the same. [Conventional technology] Today, corrosion-resistant and weather-resistant materials are used as building materials for roofs, ceilings, walls, interior and exterior panels, as well as for elevators, vehicles, bathroom vanities, bathtubs, kitchens, etc. There has been a strong demand for a metal plate that has excellent chemical resistance, heat resistance, and impact resistance, and has a beautifully colored or patterned appearance and has a high design effect. Therefore, conventionally, the surface of stainless steel sheets specified in JIS G4305 r Cold Rolled Stainless Steel Sheets was colored using a chemical coloring method in which the surface of stainless steel sheets was treated with a mixed acid of sulfuric acid and chromic acid or chromate to form a colored film on the surface. In addition, decorative stainless steel sheets have been used that have been colored by this chemical coloring method and then finished by an embossing method or the like to have irregularities on the surface. [Problems to be Solved by the Invention] However, such conventional decorative steel sheets made of stainless steel sheets are very complicated even if they are colored by chemical coloring methods, and unless strict process control is carried out, only a single color can be obtained. Because of this, the color tone tends to be monotonous, and since most of the colors are dark primary colors, it is not possible to meet the needs of a wide variety of colors, and in particular, it is difficult to obtain intermediate pale colors. Furthermore, because chemically colored stainless steel sheets generally have a smooth surface, they tend to reflect sunlight and illumination rays, creating a problem of being extremely dazzling and tiring to the eyes. Designed steel plates made of stainless steel with a textured surface reflect less light, but if the entire surface is colored, it will still exhibit a dark primary color, and intermediate pale colors cannot be obtained. The problem remained. Therefore, the present invention provides a stainless steel plate that exhibits a pale color in which each of the primary colors is diluted, does not have a strong surface gloss, has slightly anti-glare properties, and gives a soft tone and impression as a whole, and a method for manufacturing the same. That is the issue. [Means for Solving the Problems] As a result of various studies in order to solve the above problems, the inventors of the present invention have developed a stainless steel plate having surface irregularities with a roughness in a predetermined range without directionality processed by a special processing method. is treated with chromic acid or a mixed acid with chromate to form a colored film on its surface, and if necessary, the colored film is hardened, and the surface of the colored film has a ten-point average roughness within a predetermined range. The base surface of the stainless steel plate is exposed at the convex portion by polishing it to Rz, and the area of the base surface of the stainless steel plate occupies an area ratio of a predetermined range to the total surface area. The present invention was completed by discovering that it is possible to obtain a stainless steel plate with a light surface gloss that is not very strong. DESCRIPTION OF THE PREFERRED EMBODIMENTS A stainless steel design steel sheet and a method for manufacturing the same according to the present invention will be described in detail below based on one drawing. FIG. 1 is an enlarged cross-sectional explanatory diagram showing one example of the stainless steel design steel sheet according to the present invention, and FIG. 2 is an enlarged cross-sectional view showing an example of the colored stainless steel sheet ° (material) before manufacturing the stainless steel design steel sheet according to the present invention. It is an explanatory diagram. In the drawings, 1 is a stainless steel design steel plate according to the present invention,
As shown in Fig. 2, this stainless steel plate 1 is a stainless steel plate manufactured to a predetermined thickness and width by repeating annealing, pickling, and cold rolling, and if necessary, surface polishing during the process. 2 is used as an original plate, and the surface of the original plate 2 is lightly rolled at a rolling reduction rate of 0.1 to 0.6% with a rolling work roll having a non-directional ten-point average roughness (Rz) in the range of 10 to 25 μm. The surface has a non-directional ten-point average roughness (Rz
) to form surface protrusions 3 and surface depressions 4 of more than 1 to about 12 -, and then chemical coloring treatment in which this surface is treated with a mixed acid of sulfuric acid and chromic acid or chromate, and further as necessary. The hardening treatment is performed by cathodic electrolysis using sulfuric acid or a mixed acid of phosphoric acid and chromic acid, resulting in a colored film 5 on the entire surface.
The material is the material that is formed. Stainless steel plate 2 (original plate) lightly rolled in this way
As shown in Fig. 2, a colored film 5 is formed on the entire surface of the material, but this colored material surface is further coated with a ten-point average roughness (Rz) in the range of 1 to 8 μm without directionality. As shown in FIG.
The stainless steel plate 1 remains without being removed. The stainless steel plate base surface 6 from which the coloring degree fil 5 of the convex portion 3 has been removed may be either a stainless steel plate base surface that does not have luster or a stainless steel plate base surface that has been polished to a mirror finish and has a luster. . As described above, the stainless steel plate 2, which is the original plate for manufacturing the stainless steel design steel plate 1 according to the present invention, is a rolling work roll whose surface has no directionality and has a ten-point average roughness (Rz) in the range of 10 to 257 m. The reason why the stainless steel plate 1 according to the present invention must be lightly rolled at a rolling reduction of 0.1 to 0.6% is that it exhibits a pale color tone with diluted primary colors and a glossy surface. It is not strong and has some anti-glare properties, giving a soft color tone and impression as a whole, so its surface must be in a state of roughness without directionality even before it is polished as described below. In addition, in order to achieve a predetermined surface roughness after polishing as described below, it is necessary that the surface roughness before polishing be rougher than the surface roughness after polishing, and such conditions must be met. If the surface roughness is lightly rolled using a rolling work roll having a ten-point average roughness (Rz) of less than 107n, the surface roughness will become less than the desired level in subsequent polishing, and the surface will become glossy and will not exhibit anti-glare properties, which is preferable. Moreover, if light rolling was carried out using a work roll larger than 25 mm, the remaining colored film 5a and the base surface 6 of the stainless steel plate would be clearly visible during subsequent polishing, and the overall color tone would become mottled. This is because, depending on the distance, the light color may no longer appear, which is undesirable. In this way, when light rolling is performed at a rolling reduction ratio of O81 to 0.6%, the rolling reduction ratio is 0.1%.
This is because if it is very small, less than %, the surface of the original stainless steel sheet 2 will not have a surface roughness exceeding 1 in the non-directional ten-point average roughness (Rz) described above, and if it exceeds 0.6%, This is because not only will the stainless steel sheet not have the design of the present invention as described above, but the degree of work hardening on the surface of the stainless steel sheet will increase, causing problems during subsequent processing to produce various products. Next, as such a stainless steel plate 1, the surface of the material was roughened to a ten-point average roughness (1 to 8 degrees) with no directionality.
Rz), for example, 50~
A disk with a diameter of 200 to 1,000 o+m fixed to a shaft that rotates at a rotation speed of 300 rpm is made of polyethylene foam, polyurethane foam, 6-6 nylon nonwoven fabric, or 6-6 nylon nonwoven fabric with a thickness of 5 to 100 s+m.
A synthetic resin foam or nonwoven fabric such as a nylon nonwoven fabric is applied to the surface of a stainless steel plate 2 whose entire surface is colored, at a rate of 0.01 to 0.04 kgf/.
Press to make contact so that the contact surface pressure is cm2, and depending on the case, add water or a nitric acid aqueous solution with a concentration of 7% or less 1
Abrasives with a particle size of 1 to 5 Ia, such as lubricants, are
If □, apply 700 to 1.000 g of the mixed polishing liquid to the surface to be polished through the two discs in the hollow part of the shaft and the central opening of the synthetic resin foam or nonwoven fabric attached to the discs. 5
This polishing can be carried out by moving the synthetic resin foam or nonwoven fabric at a speed of 1 to 10 m/i*in while adjusting it in a desired direction such as vertically, horizontally, diagonally, etc. while supplying ~20 Qlrd. In the method, the rotational speed of the shaft is 100~
250 rpm is more preferable, and the thickness of the synthetic resin foam or nonwoven fabric is more preferably in the range of 20 to 60 a+m. Then, to attach the synthetic resin foam or nonwoven fabric to the disk fixed to the shaft, it can be attached with adhesive or with a velvet-type fastener. It may be attached by various other methods. In addition, as an abrasive, AllI2O3, which is white in quality and does not have a unique color tone, can be used to color or make the surface of a designed steel sheet product appear colored, including during manufacturing such as polishing. It is the most preferable because it does not contaminate the manufacturing site with strange colors.
In addition, Cr2O, Fe, 03, etc. may be used, or an appropriate mixture of these may be used. If the particle size of such an abrasive exceeds 5 pm, scratches may be observed on the stainless steel plate base surface 6 of the polished surface convex portion 3, which is undesirable. A particle size range of ~3 μm is more preferred. As described above, the stainless steel plate 1 according to the present invention has a surface with a non-directional ten-point average roughness (Rz) of 1 to F3p.
It is necessary to have an uneven portion within the range of ra. This is because if the ten-point average roughness (Rz) is smaller than 1-, the surface becomes too glossy and does not exhibit anti-glare properties.
If it is larger than p, the remaining colored film 5a after polishing and the stainless steel plate base surface 6 will be clearly visible, and the overall color tone will become speckled, and depending on the viewing distance, it will no longer appear pale. The area of the stainless steel plate base surface 6 after polishing is 10 of the total surface area of the stainless steel plate 2.
~90%, which is l. This is because if it is less than 90%, there is almost no difference compared to the case where the surface of the fully colored stainless steel plate 2 is not polished, and if it is more than 90%, the surface of the stainless steel plate 2 is almost completely polished. A colored film 5 is formed on the surface concavity 4.
This is because almost no a remains.

A stainless steel plate 2, which is a stainless steel cold rolled steel strip or an original plate, having a predetermined size within a size range of 0 mm and a plate width of 600 to 1,300 mm was manufactured. Next, this original plate has a non-directional ten-point average roughness (Rz) of 1.
By continuous light rolling with a rolling reduction ratio of 0.1 to 0.6% using a relatively large diameter work roll (cold rolling mill or temper rolling mill work roll) in the range of 0 to 25 μm, Ten-point average roughness (Rz) with no directionality on the surface of the original plate exceeds 1.12. This resulted in the formation of fine surface irregularities in the range of . Stainless steel plate 2 formed with such surface unevenness portions 3.4
The surface is colored blue and gold by chemical coloring treatment and hardening treatment if necessary according to the conditions described above. After forming a colored film that looks red or green. A stainless steel plate 2, that is, a raw material, whose entire surface was colored by shearing to a predetermined size was obtained. The material obtained in this way already has anti-glare properties as shown in Figure 4, but this anti-glare property is due to the roughness of the uneven parts formed on the surface of the original plate by light rolling in the previous process. This shows that it is affected by the degree of In the same figure, A, B, and C grade materials whose surface roughness exceeds 1 and is in the range of 127 m are
By polishing the surface to a degree of ~8/a, a residual coloring degree H5a appeared on the base plate surface 6 and the fourth part of the convex part 3, and a designed steel plate having a uniform pale gloss was obtained. Furthermore, this decorative steel sheet was made into a stainless steel decorative steel sheet 1 product through a refining process such as cleaning, drying, shearing, and packaging. Now, about the stainless steel design @[1] manufactured through the above manufacturing process and its manufacturing method. A more specific embodiment will be described below. 750a+m of a temper rolling mill with a surface roughness dulled to a non-directional ten-point average roughness (Rz) of 1011m
A 5US304 cold-rolled stainless steel strip with a thickness of 1.5 mm, which was lightly rolled at a reduction rate of 0.2% using a rolling work roll with a diameter of 47 mm and had surface irregularities of 47 a with the same roughness, was processed into a continuous coloring device and the like. The strip is then passed through a hardening treatment device, where a mixed acid of sulfuric acid and chromic acid is used to uniformly form a golden colored film over the entire surface of the cold rolled stainless steel strip. This cold-rolled stainless steel strip is cut into strips with a width of 1.00 by continuous shearing equipment.
It was sheared into a steel plate 2 with an Ox plate length of 2,000 m + dimension. The sheared stainless steel plate 2 was rotated at a rotation speed of 150 rpm on a vertically arranged shaft, and a diameter of 600 mm between the disk and an elastic polyurethane synthetic resin foam (thickness: 50 m).
