Description of the Invention: [Technical Field of the Invention] Field of the Invention The present invention relates to a cold-rolled steel sheet product for hot-rolled steel strips from which a scale is adhered and composed of a stainless steel. The method, wherein the hot-rolled steel strip adhered to the skin is cold-rolled into a steel sheet product, wherein the cold-rolled steel sheet product is annealed, and the cold rolled steel sheet product is subjected to descaling treatment. In addition, the present invention has a production line for manufacturing a cold-rolled steel sheet product of (4), wherein the production line comprises at least—a cold rolling station, at least one annealing furnace, and at least one for machinery= A unit that adheres to the scale of the cold rolled steel product. " In the article, “steel sheet product” is understood to mean a strip or sheet of steel made of a non-corrosive steel or “stainless steel”. BACKGROUND OF THE INVENTION Background of the Invention In the process of manufacturing a cold rolled stainless steel sheet product, a proper formation of a melt system becomes a semi-finished product, such as a thick plate, a thin plate or a steel-to-steel hot-rolled steel strip system. Rolled and wound into a steel coil. As a result, the rolled strip is then uncoated with the steel strip - and passed through a single: under or hot-rolled cold-rolled-cold steel strip. If necessary, the hot-rolled steel strip is an additional heat treatment. . In the cold rolling process, the rolled steel sheet will harden, and as a result, the quality of the cold steel strip after the formation will be greatly reduced. For cold rolling to eliminate this so-called "cold work hardening", the steel strip is usually heat treated, with annealing at a relatively high annealing temperature. The very fine scale which remains evenly adhered to the surface after annealing is removed in the pickling unit, and after the mechanical removal of the skin, the cold steel strip is guided through the pickling unit. A typical example of one of the above types of production lines is described in German Patent DE 691 26 699 T2 (European Patent EP (4) 9 177 B1). According to the prior art, in order to increase the efficiency of removing the scale adhered to the annealed steel strip, the pickling unit can be combined with a mechanically effective stripping unit. For this purpose, a scale cleaner is actually used, and the rough scale adhered to the anneal steel strip is removed in the cleaner. In addition, it is common to set a - button unit or a - unit to mechanically separate the larger scale particles that are still adhered to the cold strip when leaving the billiograph. To complete the manufacturing process, if necessary, the steel strips are additionally subjected to a skin pass after leaving the pickling unit to improve the strength of the fall and the stability of the inch. The continuous experience shows that the leg line is a cheek-type production line that can produce a large number of cold-rolled steel sheets from stainless steel in a shoulder-effective manner. The surface products of the steel products produced using the production line are not in many cases. Meet the current needs of the industry. SUMMARY OF THE INVENTION / SUMMARY OF THE INVENTION The Summary of the Invention differs from the background of the invention in that the basis of the present invention is to specify a method and a production line that is particularly suitable for carrying out the method. The way of benefit is to produce cold-rolled steel products with improved surface finish of 201211269 from stainless steel. Regarding the production method, according to the present invention, the goal of producing a cold-rolled steel sheet product by the town of Bengzhen Steel is achieved by completing the material in the article of the third paragraph of the patent application. OBJECTS OF THE INVENTION Regarding the production line, according to the present invention, by making the production line include the characteristics described in claim 13 of the patent application, the following will be described in more detail in the invention as described in the appended claims. The benefit of _, and the concept of the invention. According to the prior art as described in the Summary of the Invention, according to the present invention, the method for carrying out the production-cold-drying steel product is based on the assumption that the pure steel strip adheres to the skin and is composed of stainless steel, and the so-called "black skin" is cooled. Zaza did not pre-treat the scale. The method according to the invention additionally comprises an annealing step to soften the cold rolled material. According to the present invention, the money is removed to the skin to separate the cold rolled steel product from the scale adhered to the product. According to the present invention, after the hot dry steel strip is subjected to cold rolling, the cold-rolled steel sheet product is subjected to a de-skinning treatment in a hard-rolled state before annealing, wherein the hot-stained steel sheet product is mechanically removed. . Therefore, the hot rolled cold steel strip is mechanically removed by annealing according to the method of the present invention. In this context, another aspect of the present invention has the advantage that, in fact, part of the recording has been broken during the cold drawing and thus can be easily separated from the cold rolled steel product. The advantage of this procedure is that, in contrast, the hot dry cold steel strip is applied to its free surface during mechanical removal of the recording operation: Millennium 201211269 is not sensitive. Therefore, the surface deformation of the hard-rolled material when it is subjected to the removal of scale is much smaller than that of the relatively soft, and softer steel strip after annealing, which is subjected to conventional surface removal during the work of removing scale. According to the present invention, the steel sheet product which is separated to the maximum extent of the rough scale is then passed through an annealing unit of m, wherein (4) the conventional annealing step is performed to eliminate the stainless steel during the cold rolling process and may be mechanically removed. A further hardening phenomenon that occurs during the step. On the other hand, unlike the steel sheet product which is prone to corrosion during the annealing step, the steel strip or steel sheet composed of stainless steel forms only a small amount of new scale on the surface of the individual steel sheet product during the subsequent annealing treatment. These skins are then removed in the n-washing unit. Therefore, according to the present invention, it is not necessary to perform a special mechanical descaling operation between the product leaving the annealing furnace and entering the pickling unit. After annealing, the stainless steel sheet can additionally pass through a unit for improving surface uniformity as needed. This object has been achieved in the prior art using, for example, a tensile bending unit or the like. Corresponding to the features of the method according to the invention as described above, a production line for producing a cold rolled steel sheet product consisting of stainless steel according to the invention comprises at least one cold rolling station, at least one annealing furnace, and at least one mechanical means The unit adhered to the scale of the cold rolled steel product is removed, wherein the direction of transport of the cold rolled steel product is examined, and the at least one unit for mechanically removing the scale is disposed before the inlet of the annealing furnace. According to the present invention, since the damage caused during the stripping operation performed after the cold rolling and before the annealing is performed, it is manufactured according to the present invention 201211269, and the surface is refined by a stainless steel. The best surface: the steel strip and the steel sheet have an optimized mechanical removal of the material. The object of the invention (4)/, before the annealing, has already been used for the purpose of achieving the unit according to & In the production line, but two = Γ. Therefore, the procedure according to the present invention does not result in an increase in the cost of finance' while significantly improving the quality of the obtained product. Although '(d) the present invention, the mechanical de-skinning operation performed prior to entering the annealing furnace can be performed by a plurality of programs which can perform 2 procedures followed by another procedure or a combination of interactions Therefore, the mechanical removal of the recording operation can be carried out by particle spraying, such as sand blasting or jet rinsing or brushing. Among them, such as the use of a combination in a corresponding unit, or in a single-in-one manner in a separate spray and brush unit, these removal of the scale member may be particularly effective. In particular, if the stripping operation is to be carried out in a particularly gentle spray pattern using fine particles, it is recommended to dry or remove any liquid present on the surface of the steel sheet product as much as possible before performing the spray treatment. In this way, it is possible to avoid the particles and the liquid which impinge on the hard-rolled steel sheet product from intermingling with each other to form a substance which is difficult to remove and which hinders the need for the removal of the scale, such as being present on the surface, or A rolling oil or similar liquid that is derived from the previous processing steps. These liquid residues can be removed by heat treatment. For example, a flame drying process is suitable for this purpose' wherein the surface is cleaned and exposed to a flame such that the liquid present on the surface evaporates or burns rapidly. By using 201211269 a so-called "combustion burner," which produces a coated flame covering the steel strip to be liquid cleaned, the flame drying method can be carried out very efficiently. This burner system is described, for example, in Germany. Patent DE 10 2006 005 063 A1. If the rust is removed from the cold-rolled hard-rolled steel product by means of a spray treatment, the treatment can be carried out by means of a liquid jet, for example a high-pressure water stream. Effect 'The liquid spray can be provided with granules which are removed by grinding to the cold rolled hard rolled steel product. These granules can be rust particles which are obtained from the cold rolled hard rolled steel product. It is possible to mechanically remove the scale of the cold-rolled hard-rolled steel sheet product by using a conventional scale cleaner, wherein the steel sheet product is adhered to the cold-rolled hard-rolled steel sheet product by bending at least one roller The scale of the steel sheet is broken. In order to obtain an optimized stability of the method, the surface roughness and mechanical properties of the steel sheet product produced according to the present invention are produced by the cold rolled steel sheet. The surface leveling rolling or temper rolling may be carried out after annealing as needed. The method according to the invention can be carried out in an intermittent manner or in a continuous passing manner, depending on the number of cold rolling steps to be carried out and the technology of the factory. If the method is to be carried out in a discontinuous manner, the cold rolling can be carried out, for example, in a multi-stage operation on a reversing mill, regardless of the operation of the annealing furnace. The advantage is that the cold-rolled steel strip can A high degree of overall deformation and a relatively high degree of cold work hardening are obtained, and thus with the addition of a particularly hard surface, the mechanical removal of the scale has a very low effect on the surface. The method is carried out in a coherent manner for example In order to save a large number of steel products for the purpose of saving 8 201211269 time, and by -as or more cold rolling stations, the thickness of the steel plate can be significantly reduced. According to the present invention, the continuous production line is taken as a towel. The difference in conveying speed between the stations can be arranged by at least one steel strip storage in the transporting of the steel products. Compensating according to the present invention, and the steel sheet product composed of stainless steel has a surface roughness Ra, and the range of the relativity is 〇_micron, which does not require measures for the purpose of obtaining money, and the material belongs to The procedure of the invention. If the unrecorded steel strip is subjected to the illusion rolling after annealing, a particularly low surface roughness is obtained, which varies up to 1%, specifically 丄~7%. The invention will be explained in more detail below with the aid of a schematic representation of an exemplary embodiment.

The liquid jet is ejected through a high pressure and impacts the surface of the steel strip to be recorded with a high degree of motion, and in this procedure, the particles can be entrained to increase the effect of the skin removal. These particles may be recycled skin particles having a certain particle size which is mixed with a liquid such as water to form a jet stream. When it passes through the continuous annealing furnace 11, the non-scale steel strip (10) is heated to -temperature' where the hardened microstructure of the (4) E is softened again. The length of the continuous annealing furnace 11 is such that the length of the belt-belt passes through the crucible_speed and the annealing temperature is 4 integrals so that the steel strip microstructure obtains the desired degree of softening at the end of the continuous annealing furnace. Of course, the continuous annealing furnace u can be divided into multiple = regions to achieve this, in which different temperatures are exhibited in order to be able to deliver the best annealing results. Due to its alloy composition, only a small amount of new skin is formed on the unrecorded steel belly, independent of the relatively high annealing temperature, and 12 201211269 thus minimizes the possibility of corrosion. When the steel strip leaves the annealing furnace, the amount of scale adhered to the stainless steel strip E is very small, so that in the pickling unit 12, the effect of the pickling agent directly acting on the stainless steel strip E can be achieved as much as possible. Remove the scale from the stainless steel strip completely. However, before entering the pickling unit 12, the stainless steel strip E still needs to pass through the stretching and bending unit 17 disposed in the conveying direction F only behind the annealing furnace. In this tensile bending unit 17, the stainless steel strip E is deformed in a known manner by changing the direction a plurality of times, so that when the steel strip directly enters the pickling unit 12, it passes through the stretching and bending unit to pass the acid behind. The steel strip of the wash unit will have an overall improved surface uniformity. The surface leveling rolling after leaving the pickling unit 12 is particularly suitable for improving the surface longitude of the stainless steel strip E, wherein in addition, the steel strip is wound into a coil 3 or 4 in the winding unit 16. In the past, the stability and mechanical properties of the inch were also optimized. The surface roughness value can be almost halved by performing temper rolling, which is a typical deformation degree of 5 to 7%, so that an optimum smooth product can be obtained after temper rolling.
