摘要： PURPOSE:To control the flatness of a steel sheet in high precision by enabling the continuous detection of the shape of the steel sheet and operating separately the right and left sides of sink roll or supporting rolls even in the case of being the unsymmetrical steel sheet in the right and left sides. CONSTITUTION:From the coating weights W1, W2 on the front and back surfaces of the steel sheet by using a sheet width direction scanning coating weight measuring instrument 5 for measuring the coating weight in the width direction of the steel sheet 1, a displacing quantity DELTAD=(ln W1-ln W2)/K is calculated with a shape arithmetic device 6 to obtain the steel sheet shape. The shape obtd. from this method is approximated to a quaternal expression and by separating the shape into the symmetrical component and the unsymmetrical component, a linear expression is established between warpage rate of each component and the displacing rate of shifting quantity in the right and left direction of the sync roll 2 or the support rolls 3. Therefore, by using a shape control arithmetic unit 7 for deciding the operating quantity in the right and left sides of each roll and right/left and advancing/retreating driving devices 8, 9, the shape of the hot-dip coated steel sheet is controlled.

摘要： PROBLEM TO BE SOLVED: To easily and accurately execute the direct control of a dew point in a furnace by utilizing an estimated dew point model prepared from various kinds of conditions, at the time of controlling the dew point in a continuous decarburize-annealing furnace for a grain oriented silicon steel sheet. SOLUTION: At the time of annealing the grain oriented silicon steel sheet in the continuous decarburize-annealing furnace for steel sheet which is classified as a heating zone, decarburizing zone, reducing zone and cooling zone, a model expression for estimating the infurnace dew point in the heating zone is prepared from a humidifier set value, infurnace atmosphere gas quantity, sheet width of the steel sheet coil and steel sheet radiation rate based on the measured value of the dew infurnace point in the heating zone at the stationary time. Characteristic of the dew point in the furnace at the time of changing the humidifier set value is observed, and based on the data, an approximated dynamic characteristic model with a useless time and the temporary delay is prepored. The humidifier set value for achieving a target value of the dew point in the furnace decided for each kind of steel is calculated from the dew point estimation model and set to the humidifier, and since the dew point in the furnace is easily and directly controlled, the unevenness of the film oxidation quantity in the steel sheet is regulated within the target value with excellent control accuracy and the annealing yield is improved.

摘要： PURPOSE: To correct precision for position detector of steel sheet and to control dispersion of coating weight by utilizing function approximation on calculated distance between traveling steel sheet and gas wiping nozzle, calculated from plated coating weight in downstream of plating equipment, and distance between the steel sheet and gas wiping nozzle detected with position detector of steel sheet. CONSTITUTION: Estimated distance X between steel sheet 1 and gas wiping nozzle 5 is calculated by using an equation I (where, D is distance between steel sheet and gas wiping nozzle (m 50m), W is coating weight (kg/cm ), P is gas wiping pressure (kg/cm ), V is passing speed of sheet (m/min), K0 to K3 are constants for each kinds of steel) from detected coating weight of a measuring instrument for plated coating weight utilizing fluorescent X-ray intensity, and gas wiping pressure corresponding to the coating weight and passing speed of sheet. Estimated distance X and distance Y between steel sheet 1 and wiping nozzle 5 measured by the steel sheet position detector corresponding thereto are function-approximated like equation II. The equation II shows precision character of steel sheet position detector 6. Accordingly, since output value after correction of the steel sheet position detector 6 is calculated by equation IV, considering precision character, linearity if inverse function of equation II, equation III is used, the output value is corrected by correction arithmetic unit 99.
