摘要： PURPOSE:To uniformly control the vapor deposition thickness in the widthwise direction of band steel by using a learning vapor deposition chamber pressure coefficient obtained from the actual and theoretical values of the Zn vapor deposition chamber pressure when the metallic vapor-deposited layer of Zn, etc., is formed on the surface of band steel by a continuous vacuum deposition device. CONSTITUTION:The band steel 1 is continuously transferred by a rolling roller 4 from (a) to (b) in a vapor deposition chamber 3, a molten Zn bath 6 in an evaporation vessel 5 is heated by a heater 9 and evaporated, and the obtained vapor is passed through a duct 8 provided with a shutter 11 and a film thickness distribution controlling plate 15 to vapor- deposit Zn on the surface of the band steel. The stability of the Zn deposition control system of the device is judged. When the system is stabilized, the actual data such as the deposition amt. and a line velocity are collected, the ratios of the actual vapor deposition chamber pressure PX obtained by the inverse calculation from the data to the theoretical vapor deposition chamber set pressure PO, namely the learning vapor deposition chamber pressure coefficient CP=PO/PX, are statistically processed into a data table stratified in accordance with the specifications of the band steel, and stored in an arithmetic unit 23. A vapor deposition pressure setting calculation equation is adjusted on a line by using the values of CP, and reflected on the succeeding pressure setting. The Zn vapor deposition amt. in the widthwise direction of the band steel is thus uniformized.

摘要： PURPOSE:To obtain a good and uniform vapor deposited metallic film on the surface of a steel strip by parting the heating element internally mounted to a wrap roll for the steel strip provided in a vapor deposition chamber to >=3 parts in the axial direction of the roll and controlling the temp. distribution in the axial direction of the roll. CONSTITUTION:The steel strip 10 entering the vapor deposition chamber G from an inlet side differential evacuation chamber V1 is wrapped around the wrap roll 1 and is delivered to an outlet side differential evacuation chamber V2. The heating elements 4a-c which are divided to >=3 parts are provided to the above-mentioned roll 1 in the axial direction thereof. The temp. distribution at >=3 points in the transverse direction of the steel strip 10 is then detected by temp. detectors 5a-c and the outputs of the heating elements 4a-c are controlled. The heat is transferred by contacting to the above-mentioned steel strip 10 at the temp. gradient given in the axial direction of the roll 1. The temp. distribution in the transverse direction of the steel strip 10 in the stage of vapor deposition is thus made uniform and the good and uniform vapor deposited metallic film is obtd.

摘要： PURPOSE:To make the coke charging of given coke safe and ready, by controlling the concentration of combustible gases in a coke charging hopper with a quenching inert gas to give a given concentration. CONSTITUTION:A quenching inert gas 5 is made to flow into a coke charging hopper 2 at a given flow rate in a period from charging coke into a coke charging hopper 2 and closing a hopper lid 3 to reducing the concentration of combustible gases (G) in the coke charging hopper 2 to a specific value or below, and a mixed gas in the coke charging hopper 2 is taken out at a given flow rate to reduce the concentration of the cmpbustible gases (G) in the coke charging hopper 2 rapidly to a given value or below and discharge the gases (G) from the coke charging hopper 2. After the end of the period, the length of the period is judged whether it is longer or shorter than the given period to control and correct the gas flow rate.

摘要： PURPOSE:To improve the quality of a product by providing the 1st and 2nd coils around a casting mold, supplying respectively AC currents of different phases thereto and generating rotating magnetic fields in an ingot. CONSTITUTION:U-shaped iron cores 12, 13 are provided on both end sides in the transverse direction of the casting mold 10 and the 1st coils 14a, 14b and the 2nd coils 15a, 15b are disposed thereto. The rotating magnetic fields H1, H2 which rotate in the same direction as the rotating direction of a clock are formed when the AC currents of the phases different from each other by 90 deg. are supplied to the coils 14a, 14b and the coils 15a, 15b. Eddy current are induced in the molten steel 11 by such magnetic fields H1, H2 by which the rotating force is generated. Since the rotating force acts horizontally on the molten steel 11, the molten steel is horizontally stirred. The quality of the product is improved by the above-mentioned method.

摘要： PURPOSE:To judge whether a coil is mountable or not, by collating the inner- diameter hole of a coil carried into a prescribed position, between the mandrel of a payoff reel and an image sensor on the extension of the axial line of mandrel, by using the image sensor to detect the positional deviation of coil inner- hole and the existence of foreign matters. CONSTITUTION:The inner-diameter hole of a strip coil 8 mounted on the prescribed position between the mandrel 7 of a payoff reel and an image sensor 9 on the extension of the axial line of mandrel 7, is collated by the revolving image sensor 9 of a revolving mechanism 10. The positional deviation of the inner-diameter hole is detected by judging whether the collating area of the hole lies between the allowable outer and inner-diameter quantities of a video output, or not; the loose winding of coil or the existence of foreign matters is detected when even a part of the collating area comes off the allowable inner-diameter quantity.

摘要： PURPOSE:To safely control combustion in a continous annealing oven with the low ratio of residual O2, by subjecting systems for controlling the flow rate of fuel gas and the pressure of exhaust gas to restrictions on the basis of detection signals from detectors for detecting the pressure of exhaust gas and the flow rate of fuel gas, respectively. CONSTITUTION:In the combustion zone 1 of a continuous annealing oven using a suction pressure-type radiant tube 2, a signal from a temp. detector 3 is inputted to a regulator 4 for controlling the in-oven temp. A signal from a detector 5 for detecting the pressure of exhaust gas (b) is used in an arithmetic unit 7 to correct the temp. and in an arithmetic unit 8 for calculating the optimum flow rate of fuel gas (a) to perform the calculation, compared with a signal from the regulator 4 in a selector 9 to choose a lower one and then handled as a setting signal for a regulator 10 for controlling the flow rate of fuel gas. On the other hand, the higher one is selected from the signals from the regulator 4 and a detector 12 for detecting the flow rate of fuel gas by a selector 13 and handled as a setting signal for a regulator 16 for controlling the pressure of exhaust gas (b). Against external disturbance, the system for controlling the flow rate of fuel gas is subjected to restriction on the basis of the detection signal from the detector 5, while the system for controlling the pressure of exhaust gas is subjected to restriction on the basis of the detection signal from the detector 12.
