摘要： PURPOSE: To provide a manufacturing method of a shape detection roller which allows forming of a hard to peel very hard lining layer by a spray coating. CONSTITUTION: A plurality of discs 2 each containing a pressure sensor 1 are arranged successively concentric on an outer circumference part to form a roller material. The roller material is deoiled and the outer circumferential surface of the roller material undergoes a blasting treatment. Then, the outer circumferential surface is spray coated with a very hard lining material. In the manufacturing method of a shape detection roller, the roller material is preheated after the blasting treatment and then, the outer circumferential surface of the roller is spray coated with the very hard lining material.

摘要： PURPOSE: To provide a shape detection roller which eliminates possible surface defect on the surface of a rolled plate material attributed to the use of the shape detection roller. CONSTITUTION: In this shape detection roller, a plurality of discs each containing a pressure sensor are arranged successively concentric on an outer circumference part and a gap 11 is formed between outer circumferential upper parts 9 and 9 of adjacent discs to prevent the outer circumferential upper parts 9 and 9 from interfering with each other. An angle part of each outer circumferential upper part 9 is chamfered. The radius of curvature of the chamfered part 12 is 5μm or more while the total W of the lengths of the gap 11 on the outer circumferential surface of the roller and the chamfered parts 12 of the adjacent outer circumferential upper parts 9 is 500μm or less.

摘要： PURPOSE:To make the prevention of the breakdown of a steel strip possible by using the 2nd intermediate driving rolls of roughened initial surface roughness in cold rolling of a stainless steel strip with 20-stage Sendzimir rolling mills. CONSTITUTION:In cold rolling of a stainless steel strip S with 20-stage Sendzimir rolling mills, the initial surface roughness of the 2nd intermediate driving rolls 3 is set >=0.8mu (Ra) up to 1.6mu (Ra). If the roughness of the rolls 3 is increased in this way, the generation of slips between said rolls and the 1st intermediate driving rolls 2 is obviated and the breakdown of the strip S is prevented. Hence, the possibility of damaging work rolls 1, the rolls 2, the rolls 3, the 2nd intermediate idler rolls 4, and backing bearings 5 in accordance with the breakdown of the steel strip is eliminated and this is helpful for improvement in productivity.

摘要： PURPOSE:To provide a metal plate having uniform color tone from any angle with securing glare prevention by making the shape of cross section right angle to the metal surface projecting part circular arc in a metal plate having many of microscopic ruggednesses on surface. CONSTITUTION:The acid resistant resing incorporating a light absorbing agent is uniformly applied on roll surface with the prescribed thickness. The surface is irradiated with the pulse state beam from YAG laser oscillator having Q switch with traversing in the roll axial direction. The resin in the part to form a recessed part is removed with controlling the output timing of pulse so as to obtain the required pattern. Ruggedness pattern is formed by etching the roll surface with an acid corrosion agent. In this etching, the cross section form right angle to the metal surface of etched surface is made to a circular arc. By using the roll with Sendzimir mill, the ruggedness pattern of microscopic projecting part 1 and recessed part 2 is transferred on SUS430 steel plate. By this method, the metal plate having dull finish surface, securing glare prevention and being dependent less on an angle of reflection strength is obtained.

摘要： PURPOSE:To prevent a surface folding generating in the intermediate part of a belt-like material at the time of taking-up by gradually increasing a drawing down force at the time of a rolling start in an initial pass to gradually decrease the change of a thickness, gradually decreasing a drawing down force at the time of the completion of rolling to gradually increase the change in the thickness at a tip part at the time of the completion of rolling. CONSTITUTION:At the time of the start of the rolling of each pass, the total drawing down quantity (t0 - t1) of the pass, is gradually added to the intermediate part on one end side of a belt-like material existing between an upper and a lower rolling rolls, and the change of a thickness at the tip part of a rolling start, is allowed to gradually reduce in a tapered shape or by stages. Further at the time of the completion of each pass, the total drawing down quantity (t0 - t1) of the pass, is gradually released from an intermediate part on another end side of the belt-like material existing between the upper and the lower rolling rolls, the change in the thickness at the tip part of a rolling completion, is allowed to gradually increase in a tapered shape or by stages. Consequently, a difference in level in rolling, generating at the tip part of the rolling start of the belt-like material and at the tip part of the rolling completion, can be adjusted so that it becomes within an allowable difference in level in which the surface folding is not generated at the time of taking-up, and the surface folding caused by the difference in level in rolling, can be prevented.

摘要： PURPOSE:To obtain a stainless steel band having uniform color tone by continuously measuring the intensity of reflected light on the steel band surface in a pickling after dull-rolling and controlling the pickling condition. CONSTITUTION:In an annealing-pickling process or a pickling process after the dull-rolling to the stainless steel band, the variation of the color tone in the longitudinal direction of the steel band surface after pickling is continuously measured by brightness (cd/m ) on the reflected light intensity. Based on this result, the pickling condition is controlled to obtain the dull-finished stainless steel band having uniform color tone in the longitudinal direction. In the last color tone adjusting process of the dull-finished stainless steel band, the color tone evaluation in on-line can be executed. Based on this result, by controlling the pickling condition, the color tone in the longitudinal direction of the steel band can be controlled at one process.
