摘要： PURPOSE: To control the flattening of a hot dip coated steel sheet with high accuracy and to control the simple C camber with high accuracy thereof. CONSTITUTION: The shape of the coated steel sheet 1 is determined by a shape calculating device 8 from the plating coating weights on the front and rear surfaces of the respective transverse directions measured by an instrument 7 for measuring the plating coating weight of scanning in the transverse direction of the sheet which measures the respective plating coating weights on the front and rear surfaces in the transverse direction of the steel sheet by detecting the intensity of the fluorescent X-rays received after irradiation of the steel sheet traveling past a gas wiping area from a hot dip coating bath with γ rays or X-rays in its transverse direction. This control method for making the plating coating weights of the hot dip coated steel sheet uniform comprises approximating the resulted steel sheet shape with a quartic function and determining the installation positions of auxiliary dies 5 arranged in plural pieces on the front and rear of at least either of above and below wiping nozzles 4 in the transverse direction of the steel sheet 1 and the pressure of auxiliary dies 5 by an arithmetic unit 8 using the maximal value and minimal value of the function. The auxiliary dies 5 are then moved by a driving device 11 to the resulted set positions and the pressure of the auxiliary dies 5 are controlled by a pressure controller 10.

摘要： PURPOSE:To accomplish both quick responsiveness and stability by outputting an output influence parameter value obtained by synthesizing an output of a PI operation high in speed of response and an output of a PI operation low in speed of response in the rate of a 1st weight value to a 2nd weight value to a control object instrument. CONSTITUTION:When the deviation of an instrument output from a target value is large, correction of the output influence parameter functions at a high speed and instrument output control high in response is realized. On the contrary, when the deviation of an instrument output from a target value is small, correction of the output influence parameter functions loosely and an instrument output high and stable in precision is realized. Since the speed of response changes continuously in accordance with continuous decrease of deviation values, the instrument output is not fluctuated by the change of the speed of response.

摘要： PURPOSE:To execute effective carrying and flow rate control to molten metal passing through round flow passage by equally sifting plural circular arc type linear motors the circular direction and rotating each linear motor at the same speed. CONSTITUTION:By forming the circular arc type linear motors 1-3 to multi steps and also equally shifting each step of the divided parts, almost uniform electromagnetic force is generated to the circular direction as the whole. Then, by rotating each linear motor 1-3, the uniform electromagnetic force to the circular direction can be generated. Further, the electromagnetic force rotating to the circular direction is generated and by executing rotating motion to the molten metal, centrifugal force acts to the molten metal itself. By this method, as the molten metal at center part of the carrying passage is worked to outer diameter direction with the centrifugal force and the controllability is improved, the control efficiency to the molten metal at center part can be improved.

摘要： PURPOSE:To improve the accuracy of gagemeter formula by determining the amount of roll wear/expansion in each stand and executing screw down position setting of the next material and screw down position correcting control on the way of passing sheet between the stands. CONSTITUTION:The thickness control is executed in a continuous hot rolling mill having plural rolling stands 1-7 and loopers between the stands. The thicknesses on the outlet sides of the respective stands 1-7 are measured based on a mass flow fixing formula with a thickness gage 10 on the outlet side of the final stand 7, thickness gage 11 which is installed between arbitrary stands and respective looper rotation detectors 21-26 between the stands. Errors between this thickness and the estimated thickness that are determined by a formula for estimating thickness on the outlet side of an own stand itself that consists of the load and actual result of screw down position at the own stand itself are determined. The amount of roll wear/expansion of each stand is determined from them and the screw down position setting of the next material and screw down position correcting control on the way of passing sheet between the stands are executed. In this way, the reduction of off-gage length can be realized.
