摘要： PURPOSE: To prevent generations of surface flaw and strain in cold rolled steel sheets by adjusting damper opening of a plenum chamber based on temp. distribution in the steel sheet width direction at inlet and outlet sides of the cooling roll part in a cold rolled steel sheet cooling apparatus using both of said chamber and cooling roll.
CONSTITUTION: The cold rolled steel sheet 2 carried continuously in arrow direction in a cooling zone 1, is cooled by passing between the plenum chambers 3 opposed at both surfaces, further cooled by plural cooling rolls 4. Temp.s in the sheet 2 width direction are detected by temp. detectors 5, 15 at inlet and outlet sides of the cooling roll part respectively, and the signals converted by converters 6, 16 are entered to a calculator 7. Parameters of cooling calculation model at the cooling roll parts divided imaginally in said width direction are obtained statistically, and cooling calculation is performed by using respective parameters in the width direction. Estimated temp. distribution at inlet side of said roll is obtained so that temp. distribution in said width direction at outlet side of said roll corresponds to the necessary aimed value, and respective openings of plural dampers 19 provided parallelly in said width direction are adjusted so that the distribution is obtained.

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.

摘要： PURPOSE:To correctly detect the contamination level of the surface of a molten metal by measuring the thickness of a metallic film vacuum-deposited on a hoop, the temp. of the molten metal and the opening degree of a shutter and by calculating a coefft. from the measured values. CONSTITUTION:The thickness of a metallic film vacuum-deposited on the surface of a hoop 10 introduced into a vacuum deposition chamber 1 is measured at the outlet of the chamber 1. The temp.of a molten metal 11b in the chamber 1 and the opening degree of a shutter are also measured and a coefft. is calculated from the measured values. The contamination level of the surface of the molten metal is detected by making use of the fact that the thickness of the metallic film is proportional to the temp. of the molten metal 11b and the opening degree of the shutter but is reduced when the surface of the molten metal 11b is contaminated.

摘要： PURPOSE:To prevent the negative pressure of a pressurizing chamber or cooling chamber without generating hunting by supplying gaseous nitrogen to a sealing roll chamber or cooling chamber which is a post stage of the pressurizing chamber. CONSTITUTION:A steel sheet 7 is conducted via the pressurizing chamber 1 and sealing roll chamber 3 to a vacuum deposited chamber. The gaseous nitrogen is filled in the pressurizing chamber 1 through a supply path 8. The gaseous nitrogen leaks between the pressurizing chamber 1 and the outside of sealing rolls 4 on passing of the weld zone of the steel sheet 7. A pressure fluctuation is detected by a differential pressure transmitter 10 when a differential pressure arises. A control valve 12 of the gaseous nitrogen supply path 8 is automatically released through the control valve 11 and the prescribed amt. of the gaseous nitrogen is replenished into the pressurizing chamber 1. A control valve 15 of the supply path 9 is opened at the same instant and the prescribed amt. of the gaseous nitrogen is supplied into the chamber 3. The generation of the negative pressure in the pressurizing chamber 1 is thus prevented.

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 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.
