摘要： PURPOSE:To improve the productivity, and to reduce the cost of equipment by performing beinding to a hot-rolled sheet steel by giving a tension of a specified elongation percentage, breaking down a scale on the surface of the sheet steel, and thereafter, pickling it. CONSTITUTION:A hot-rolled sheet steel 25 is fed to a scale breaker through an entry bridle roll 15. In the scale breaker 16, the sheet steel 25 is given a tension by the bridle roll 15 and a delivery-side bridle roll 19, and also receives a bending action by a roll group. Accordingly, the sheet steel 25 is subjected to drawing, bending and elongation. Thereafter, its scale is removed partially by sprinkling cooling water by a brush grinding roll 17, and thereafter, the sheet steel 25 passes through the roll 19 and its scale is removed by a pickling tank. According to this method, the scale can be removed in a short time, therefore, a passing speed of a descaling line is improved. Accordingly, the production is improved, also the length of the pickling line is shortened, and the cost of equipment is reduced.

摘要： PURPOSE:To obtain a titled device capable of measuring the tension of a material accurately and detecting the meandering even if its quantity is small by constituting the device wherein the load of a roll is received by load cells disposed at the inside of bearing parts through a frame which connnects the bearing parts located at both sides of the roll. CONSTITUTION:A tension meter device of a rolling mill is constituted by pivotally supporting a bracket 13 attached to a frame 10 which connnects roll chocks 3, 3 located at both sides of a roll 2 of rolling mill, and a bracket 15 on a fixed frame 16, at the position just below a pass center C, and installing a pair of load cells 1, 1 at both sides of the center C and at the inside of said chocks 3, 3. By said device, the tension of a material to be rolled is accurately detected by receiving a load loaded from the material 8 on the roll 2 by the load cells, 1, 1 and also even the small quantity of material meandering is detected basing on the difference between the loads of load cells 1, 1 located at both sides when the material 8 deviates from the pass center C and meanders.

摘要： PURPOSE:To continuously roll an excellently shaped sheet material over a wide range of sheet breadth, by rolling a jointed part between two sheet materials while ajusting a contact position between the sheet material and a work roll and a roll bending force, in case of rolling sheet materials of different breadths. CONSTITUTION:When a jointed part between two sheet materials is detected by an optical device, etc., at a proper position on the feed-in side of a rolling mill, an intermediate roll 12 is automatically shifted in the direction of roll axis so as to make the roll crown of a work roll 11 conform to a material to be rolled next, and besides, the roll bending force of a roll bender 14 is also adjusted. The position delta of the intermediate roll 12 (a distance between the side edge of rolled material and the side end of the intermediate roll 12), that is the distance of the side end of the intermediate roll 12 from the contact point between the work roll 11 and the material, is adjusted; hereby, the distribution of rolling pressure is changed, and the roll crown is also changed. Hereupon, the intermediate roll's position delta and the roll bending force are correlatively changed.

摘要： PURPOSE:To measure the sharpness of a steel plate or a rolling roll after painting by performing band-pass in the specified size range from the curve of the surface texture of the steel plate or the rolling roll, and measuring the slant angle on the obtained waviness curve. CONSTITUTION:When the wavelength component of the cross-sectional curve of the surface texture of a steel plate or a rolling roll in the range of 0.2-5mm, is taken out, for example, the function, wherein the straight line, an arc and the like most close to the cross-sectional curve obtained at the first measurement are specified, is obtained. The function correction or the like, which subtracts the component of the function and removes the long wavelength component, is used. When the slant angle of the waviness of the wavelength component in the range of 0.2-5mm is measured, for example, the slant angle at the point, which is separated by the specified length (the short cutting length: selected in the range of 0.2-5mm) for each point constituting the waviness curve with the point as the center, is obtained by the specified expression. Then, the absolute value of all points undergo arithmetic means, and the result is made to be the slant angle representing the measured plane. The computing method between two points and the like such as this are used.

摘要： PURPOSE:To detect whether welding is normal or not, by arranging plural magnetic detecting elements dispersedly along the butt part between the rear end of a preceding steep plate and the front end of a trailing steel plate. CONSTITUTION:The magnetic detecting elements for magnetic field distribution detection are arranged dispersedly along the weld zone. Namely, when they are equipped to an electrode, grooves 60 are formed in the electrode 30 on the top surface side in a comb-tooth shape; tips (on a steel plate end side) of the teeth are made deep to arrange detection coil 7 therein, intermediate parts are made shallow to run lead lines 7a of the detection coils 7 therein, and the other-end common part is made slightly deeper to allow the lead lines to run therein. A magnetic field produced by a current flowing through the steel plate during flashing and upsetting is detected to find =>1 of a flashing frequency distribution, flashing mean current distribution, flashing heat input distribution, upsetting mean current distribution, and upsetting heat input distribution from respective output voltages of the detecting elements, thereby detecting whether the welding is normal or not.

摘要： PURPOSE:To improve the accuracy of sheet thickness, by restricting the speed of the whole stand while controlling also, as an object of speed control, the speed of bridle rolls provided to the inlet side of a tandem mill. CONSTITUTION:Unlike conventional methods, an automatic speed controlling circuit (ASC) 40 is provided to bridle rolls 10 to control the speed v0 of a sheet material at the inlet side of the No.1 stand 11. Then h1D is constantly maintained by an equation (h1E, h1D: sheet thickness at the inlet and outlet sides of the stand 11, v1: speed of the sheet at the outlet side of the stand 11) even when a rolling down force of the stand 11 varies. The thickness of a running sheet 1 is sampled by a sheet thickness detector 51 to store it in sequence in a memory 61, and the memory 61 acting as a shift register is shifted by a clock the same one for sampling. A delay equal to the time required for transferring the sheet 1 from the detector 51 to the stand 11 is given to obtain the sheet thickness h1E, which is inputted to an arithmetic device 71 to obtain the sheet thickness h1D by calculating the speed v0, v1 and v0h1E/v1. In No.2-4 stands 12-14, the same calculations are performed.

摘要： PURPOSE:To improve the accuracy of sheet thickness control during the change of sheet thickness and the stability of a rolling operation by executing continuously the sheet thickness control and tension control to preset values at the point of the time when the thickness change point of a sheet material arrives at a prescribed point then changing the rolling down position and roll circumferential speed of a rolling stand. CONSTITUTION:The target sheet thickness value on the outlet side of the Noi stand determined preliminarily for a sheet thickness control device (AGC) of the Noi stand is changed from HAi to HBi at the point of the time when the sheet thickness change point arrives at the Noi stand in, for example, a 4-stand cold tandem rolling mill. The target tension value between the Noi stand and Noi+1 stand predetermined for a tension control device (ATC) between the Noi stand and Noi+1 stand is changed from TA1 to TB1 at the point of the time when the sheet thickness change point arrives at the Noi stand or the prescribed position between the Noi stand and Noi+1 stand. The sheet thickness control and tension control are thus continuously executed even during the sheet thickness change, by which the sheet thickness is changed.
