摘要： PURPOSE:To reduce the disturbance of bath temp. and to carry out stable vacuum vapor deposition, by controlling the amount of evaporation by providing the prescribed set heat power or the maximum or minimum heater power according to the opening of a shutter carrying out the instantaneous control of the amount of evaporation. CONSTITUTION:The opening of a shutter provided on the outlet of an evaporation tank is regulated according to the target value of the amount of evaporation, by which the instantaneous control of the amount of evaporation is performed. Subsequently, the control of heat balance is carried out by means of heater power to control the amount of evaporation. In controlling the amount of evaporation in the above vacuum deposition device, the above shutter opening is detected, and then, the deviation value between this detected value and the set value is determined. When this deviation value is within the tolerance, a set heater power maintaining the target evaporation amount is provided. Further, when the above deviation value exceeds the tolerance, a heater power changed according to the heater power maintaining the target evaporation amount or the minimum heater power is provided. By this method, the disturbance of bath temp. is reduced and splashing from a metal-bath surface is prevented, and further, the breakage of a heater due to thermal shock can be avoided.

摘要： PURPOSE:to improve the productivity by arranging a temp. control system and a pressure control system, previously detecting the unstable condition of the process, and forcibly switching the temp. control of band steel to a pressure control method to stabilize the vapor deposition line in an exteremely short time. CONSTITUTION:The set value of the temp. of band steel 1 at the outlet of a cooler 3 is inputted to a temp. regulator 12. The cooling gas pressure in a plenum chamber 3a of the cooler 3 is set and controlled based on the output signal from the regulator 12 through a gas pressure regulator 13. The set value of the pressure of cooling gas in the chamber 3a against the set value of the temp. of the band steel 1 is determined through an arithmetic unit 15. The set value is inputted to the pressure regulator 13 to control the pressure of the cooling gas in the chamber 3a. The stability of the process in a vapor deposition chamber 5 is detected, and all the control is switched to the pressure control system when the process is unstable to control the temp. of the band steel 1.

摘要： PURPOSE:To reduce defective parts due to the nonuniform plating of a joint by temporarily stopping information on the joint of a metallic strip in the continuous vacuum deposition plating method in which the temp. of the strip, which has been discharged from an annealing furnace and cooled, is controlled based on the information of a radiation thermometer. CONSTITUTION:A metallic strip S (steel strip) annealed in an annealing furnace 1 is introduced into a cooling chamber 2 and then into the seal roll chamber 3 of a vacuum deposition chamber. A gas blower 6 of the cooling chamber is controlled to a specified output by a computer 4, and the strip temp. is sensed by a radiation thermometer 5 set at the outlet of the cooling chamber and sent to the controller 4 to adjust the output of the blower 6. When the arrival of the strip is sensed by the computer 4, the feedback of the sensed information of the thermometer 5 is stopped at a predetermined position in front of a weld line, and feedback is resumed at a predetermined position at the rear of the weld line.

摘要： PROBLEM TO BE SOLVED: To improve accuracy in control to stuck quantity of plating and responsiveness. SOLUTION: A model equation indicating a relation among the stuck quantity of plating and factors related to the stuck quantity of plating, is preset and measured data on the factors are taken and stored in a memory (a2-a3), and the stuck quantity is measured (a4) at each time when a longitudinal direction position of the steel strip existing at the nozzle position reaches the position of a stuck quantity meter in the data-taking time. Further, the measured data of the factors at the time when the longitudinal directional position of the steel strip exists at the nozzle position, is read out from the memory (a5) and an estimated value of the stuck quantity of plating corresponding to the read-out measured data is obtd. from the model equation (a6). A deviation between the measured value of the stuck quantity of plating and the estimated value is obtd. (a7) and based on the obtd. deviation, the control target stuck quantity of plating is set (a8-a12). A control target pressure corresponding to the control target stuck quantity of plating, is obtd. from the model equation (a13) and the spouting pressure is controlled so as to become the control target pressure.

摘要： PROBLEM TO BE SOLVED: To omit the changeover process of cameras for changing the width of a metal strip and prevent an object from going out of the Camera view field. SOLUTION: A light source 15 extending across the width of a metal strip 14 is disposed over a range of the edge position to be detected on one surface of the strip 14, a plurality of cameras 16, 17 for receiving lights from the light source 15 to output electric signals having output levels corresponding to received light quantities are disposed on the other surface of the metal strip 14 with widthwise spacings so as to partly overlap their view fields adjacent in the width direction of the strip 14 and an adder 43 adds the outputs of the cameras 16, 17, thereby adding to synthesize the outputs of the cameras 16, 17. This eliminates the need of changing over the cameras 16, 17 and prevents an object from going out of the cameral view field.

摘要： PURPOSE:To minimize a waste part in changing by increasing the quantity of heat supplied to an evaporation bath and decreasing the opening degree of a shutter in a previous lot and suddenly increasing the opening degree in changing, when changing to a lot of greater METSUKE (unit, 200-2000g/m ) quantity at the middle part of a coil in continuous vacuum deposition plating. CONSTITUTION:After metal 1, such as Zn is melted in a melting furnace 2 and fed to an evaporation vessel 3 by suction and heated by a heater 5, the metal is introduced into a vapor duct 7 through a shutter 6 to plate a steel belt 8 by vapor deposition. At the change point which is two lots before the lot where METSUKE (unit) quantity is increased at one lot before, first power to the heater 5 for a metal deposition bath is suddenly increased. To compensate the increase of the evaporated quantity, the opening degree of the shutter 6 is gradually decreased to maintain the same METSUKE (unit) quantity as that of the previous lot. Next, at the change point to the lot of the in creased METSUKE (unit) quantity, when the opening degree of the shutter 6 is suddenly increased, the evaporated quantity is suddenly increased to increase METSUKE (unit) quantity. As the evaporated quantity is suddenly increased, the opening degree is gradually decreased to compensate it.
