Description of the Related Art Skin-pass rolling improves the press formability by eliminating the elongation at the yield point in ferritic stainless steel in order to flatten the shape and to bring out the flatness of the entire plate, and to smooth the surface roughness. This is an operation that has been generally performed in the past in order to improve the surface gloss.

ルの表面粗度を鋼板に転写し、平滑化を図っている。Conventional skin pass rolling is carried out by a means known as dry rolling without using rolling oil. That is, a large-diameter roll is ground with a grindstone # 1000 or more, and a multi-pass rolling is performed under a light reduction of 0.5 to 1.0% in total reduction amount, and the surface roughness of the roll is transferred to a steel sheet for smoothing.

欠陥( 押込み) が発生することもあった。However, since such conventional skin pass rolling is dry and has a large diameter roll rolling, the rolling load becomes high and many passes are required. As a result, the number of man-hours is increased and the efficiency is unavoidable. In addition, since it is dry rolling, dust and dust may adhere to the rolls and the steel sheet, causing minute surface defects (indentation).

の低いことから水溶性のものが多く使用されている。Conventionally, as a means for solving such a problem, a skin pass rolling technique using rolling oil (called wet skin pass rolling) is known. As the rolling oil used in that case, a water-soluble rolling oil is often used because of its drying property after rolling and low residual oil content.

化は問題とはならない。Certainly, although the rolling efficiency was significantly improved by such wet skin pass rolling, it was found that the surface gloss rather deteriorates in the case of ferritic stainless steel sheet. In the case of ordinary steel plates, the surface gloss is not a problem because it is often painted later, so rather it has a dull finish, and for austenitic stainless steel plates, deterioration of the surface gloss is not a problem due to the intended use. ..

A more specific object of the present invention is to change the surface gloss of a ferritic stainless steel sheet by skin pass rolling,

高光沢圧延が実現される。Means for Solving the Problems The inventors of the present invention have made various studies in order to achieve such an object, and have obtained the following findings. Assuming a reduction rate of 0.5 to 2.0% in skin pass rolling, skin pass rolling of ferritic stainless steel sheets was performed using various rolling oil solutions.
High gloss rolling is realized.

大きく関与している。 軽荷重側ではＴ方向光沢がスキンパス圧延油の動摩擦
係数の低下に伴い著しく向上している。In the wet skin pass rolling, the glossiness in the T direction is particularly difficult to improve, because the roughness in the T direction during rolling is less likely to be smooth than in the dry skin pass rolling. The dynamic friction coefficient of the skin-pass rolling oil is greatly involved in improving this. On the light load side, the gloss in the T direction is remarkably improved with the decrease in the dynamic friction coefficient of the skin-pass rolling oil.

Was found, and the present invention was completed. In the past, the coefficient of kinetic friction of water-soluble skin-pass rolling oil was 5 to 20 vol.%.

This is a skin pass rolling method for ferritic stainless steel sheets performed at 0.5 to 2.0%. Preferably, skin pass rolling oil
Skin pass rolling is performed while applying 30 to 70 ml / m 2 .

Usually, the rolling oil contains a rust preventive agent, a surfactant, a salt and the like. Even in the skin pass rolling oil according to the present invention, it is not necessary to appropriately add such a conventional additive to the present invention. It is a matter within the range of. A typical composition of the rolling oil according to the present invention is, for example, 30 to 80% by weight based on a mineral oil system, and 2% of other rust preventive agent.
Hereinafter, the oil is composed of 15% or less of the surfactant, and this is diluted with water to 5 to 20 vol%.

If it exceeds 20% by volume, on the other hand, if it exceeds 20% by volume, oil may remain. In other words, the composition of the oil is determined so that the dynamic friction coefficient is 0.25 or less at 5 to 20%. As the oil component, mineral oil, esters, etc. are usually added.

If it is less than 0.5%, the yield elongation will not disappear, while if it exceeds 2%, work hardening will occur and the formability will deteriorate. Dynamic friction coefficient: The dynamic friction coefficient is limited to 0.25 or less, preferably 0.20 or less.

This is because 400). Up to now, a large amount of surfactants and rust preventives have been added to enhance stability and rust resistance, so that a dynamic friction coefficient of about 0.3 to 0.4 has been used. However, according to the present invention, in order to improve the surface gloss in the T direction, the coefficient of dynamic friction is limited to 0.25 or less, preferably 0.20 or less.

The mechanism for improving the directional gloss is not necessarily clear, but it is presumed that the lubrication state changed and the roll surface roughness was easily transferred to the steel sheet. In the present invention, the dynamic friction coefficient can be adjusted by changing the blending ratio of mineral oil, and the dynamic friction coefficient may be adjusted by other means such as ester addition.
