摘要： PURPOSE:To improve the accuracy of fine working on the surface of a metallic strip by using liquid mercury as an energizing anode in place of an energizing roll, thereby preventing degradation in resist pattern accuracy by roll draft at the time of using the energizing roll and degradation in the surface characteristics of the metallic strip by dents, etc. CONSTITUTION:This one side continuous electrolytic etching treatment device electrolytically etches the metallic strip 5 coated with a resist to prevent contact with an etching liquid in prescribed patterns on its front surface by passing the metallic strip in cathode plates 2 of an electrolytic treating cell 9 consisting of a horizontal bath. The device described above is provided with a vessel 15 holding the liquid mercury 6 forming an anode section 1 on at least its inlet or outlet side. The liquid mercury 6 in the anode section 1 is brought into contact with the rear surface of the metallic sheet 5 by its plane tension at the time of passing the strip within the device. The vessel 15 is provided with liquid sealing means on its circumference to prevent leakage of the liquid mercury 6 outside the vessel 15.

摘要： PROBLEM TO BE SOLVED: To improve a liquid draw performance and increase a ringer roll life by providing a preceding step ringer roll, whose length is less than the minimum width of a band shape element, the latter step ringer rolls which are divided into two in width directions and are capable of shifting in an axial direction for liquid drawing both end parts only, and air wipers positioned at an inlet side for blowing a sump away from a center of the band shape element towards the end part directions. SOLUTION: Length of the preceding step ringer roll 5 is made to be less than the minimum width of the band shape element 1 so as not to generate uneven abrasion. A liquid drawing of the band shape element 1 end part is performed by the latter step ringer rolls 8. By moving an abrasion damaged part successively to outside of the band shape element width, according to the abrasion damaged condition of the latter step ringer rolls 8, liquid draw property of the latter step ringer roll 8 is not decreased and the preceding and latter step ringer rolls 5, 8 life can be elongated. The latter step ringer rolls 8 are made to shift a go/back movement in a direction of the moving direction 9, resulting in a prevention of proportional offset abrasion of the ringer rolls 8, and in an improvement of liquid draw property. Generation of the liquid draw failure can also be prevented by air wipers 30.

摘要： PROBLEM TO BE SOLVED: To prevent scattering of a liquid coolant onto a steel sheet and moreover to cool a work roll uniformly and sufficiently by providing a nozzle position adjusting device for adjusting the distance between an air jetting nozzle for removing the liquid and the work roll and pressure adjusting device for adjusting the pressure of the air jetted from the nozzle. SOLUTION: The air jetting nozzle 6 for removing the liquid is arranged on the upper side of the steel sheet 1 and the outlet side of the work roll 2. As the shape of the nozzle 6, it is preferable to use a slit nozzle and moreover the nozzle having the length of its slit opening part longer than the width of the steel sheet 1 is better. The distance between the nozzle 6 and the surface of the work roll 2 is adjusted with the nozzle position adjusting device 7. It is better to use gears or a cylinder for this adjusting device. The jetting pressure of the nozzle 6 is adjusted with the pressure adjusting device 8. It is preferable for this adjusting device to have a constitution by which the pressure is automatically adjusted to a proper pressure using a pressure detecting device 10 for detecting the pressure in the nozzle 6 and arithmetic unit 11 for processing detected data.

摘要： PROBLEM TO BE SOLVED: To execute a precise shape control of a metallic material in a feedback system by using the difference between measured tension distribution in the width direction of a strip detected on the outlet side of the pass and the measured tension distribution at the inlet side of the following pass. SOLUTION: The tension distribution in the width direction of the strip 10 is detected by providing a shape-meter 20 at the left reel 16 in a reversible rolling mill. First, the rolling reduction is executed with a roll bender 30 by using the inlet side tension distribution obtd. with the shape-meter 20 at the first pass. In the second pass, the outlet side shape is measured with the shape-meter 20 to execute the rolling reduction condition with the rolling bender 30. At the same time, a position of the longitudinal direction of a coil is measured with a pulse generator 26 to store the outlet side shape distribution. In the third pass, the outlet side tension distribution stored at the second pass is deducted from the inlet side tension distribution measured at the third pass, and the feedback control is executed only for the inlet side tension distribution at the first pass appeared as a replica of the outlet side shape at the third pass. By this method, even when the strip shape at the inlet side is not flat, the inlet side tension distribution developed in the rolling can precisely be measured.
