摘要： PURPOSE: To remove the refrigerant sticking on a steel wire rod to a permissible value or below without wasting washing water by providing means for operating the necessary flow rate of the washing water in accordance with the washing characteristic of the steel wire rod, detecting the actual flow rate, and controlling the flow rate of the washing water.
CONSTITUTION: The necessary flow rate of washing water is calculated by a calculator 8 in accordance with the diameter of a steel wire rod (d), a conveyance speed (v) and the permissible value X
0 for the remaining amt. of the refrigerant sticking on said rod in a control device for washing which removes the refrigerant sticking on the wire rod by washing. The output from the calculator 8 is determined as a target value, and the flow rate of washing water is controlled by operating a flow rate controller 12 for the washing water and adjusting a control valve 14 so that the actual flow rate of the washing water detected by a detector 13 for the flow rate of the washing water coincides with the target value. The excessive use of the washing water is thus obviated and even if the wire diameter and the conveyance speed change, the refrigerant is removed always to the permissible value or below.

摘要： PROBLEM TO BE SOLVED: To detect abrupt change of excavation force to thereby restrain fluctuation in the quantity of unloading by obtaining the fluctuation of excavation force from the excavation force according to the pressure of inclining rotation cylinder, and proportionally controlling the fluctuation of excavation force and compensating a lateral movement speed command. SOLUTION: Excavation force Fdf is obtained by a block E according to inclining rotation cylinder pressure Pkf , and after the offset error of the excavation force is removed, only the rapid change of the excavation force Fdf is made to pass and it is made to pass through a bypass filter F for removing low frequency components, then the excavation force fluctuation component Fdf is added to a lateral movement command V being a control output of a main circuit PI by the P control G for restraining the component to a targel level. As a result, the lateral movement speed command is obtained which makes the speed high as the excavation force Fdf is decreased while low as it is increased, and a lateral movement speed command value by the conventional bucket hydraulic control is compensated. The lateral movement speed command value is divided into three speeds of DE turning, boom turning and running according to the lateral movement mode set by an operator.

摘要： PROBLEM TO BE SOLVED: To insure a target cargo handling quantity regardless of unevenness of cargo handling or cargo collapse by providing a detector detecting the drilling load of a drilling part in the horizontal direction, and managing the lateral feed speed of an unloader so that the drilling force detected value by the detector becomes a prescribed drilling force target value. SOLUTION: A cargo handling quantity setting part 9 computes a lift force target value based on the sort of load and a target cargo handling quantity set by an operator, and output to a lift force computing part 10. The lift force computing part 10 proportionally and integrally computes so that a lift force detected value is equal to the target value, and outputs a correcting quantity against a drilling force target value and the reference value. The drilling force reference value is obtained by previously investigating a steady value against a rated cargo handling quantity for example and proportionally computing according to the target cargo handling quantity set by an operator. The drilling force target value corrected in this way is output to a drilling force control computing part 11. The drilling force control computing part 11 computes and outputs a lateral feed speed command value to a drive device 12. The drive device 12 operates an unloader main body 16 for cargo handling.

摘要： PURPOSE:To control adequately the temp. of a refrigerant even if conveyance of a steel wire rod is interrupted for short time when an operating condition is changed in a method for controlling an installation which subjects the steel wire rod after hot rolling to a direct heat exchange by specifying the control when the conveyance of the steel wire rod is interrupted and resumed. CONSTITUTION:A steel wire rod 1 in a looped state is immersed in a refrigerant, for example, molten salt 3, in a cooling vessel 2 and is thus cooled. The refrigerant 3 heated by the wire rod is circulated between the vessel 2 and a heat exchanger 5 by a pump 4 so as to be subjected to a heat exchange with cooling water 6, by which the refrigerant is cooled. When the final end of a preceding material 1 passes through the vessel 2 owing to a change in an operating condition such as a change in a wire diameter, a calculator 14 applies the target value T2 of the refrigerant temp. in the vessel 2 calculated from the input data for the operating condition of the succeeding material to a temp. control device 7 by which a flow rate adjusting system is controlled until the temperature detected with a detector 8 attains T2. The quantity of the heat extraction is thus decreased as far as possible while the supply of the water to the heat exchanger and the circulation of the refrigerant are continued. When the front end of the succeeding material passes through the vessel 2 and the temp. detected with the thermometer 13 rises to the permissiblemin. temp. or above, the refrigerant temp. T21 on the inlet side of the vessel 2 for the succeeding material calculated by the calculator 14 is applied to the device 7.

摘要： PURPOSE:To wash away the refrigerant sticking on a steel wire rod to a permissible value or below in the stage of washing away the refrigerant sticking to the steel wire rod by determining preliminarily the lowest flow rate of the washing water meeting an operating condition and controlling the flow rate to the lower limit value or above. CONSTITUTION:The detection signal of a refrigerant concn. detector 14 disposed in a washing tank 4 is inputted to a concn. controller 13 in the stage of washing the refrigerant sticking to a steel wire rod. The controller 13 feeds the output therefrom to a lower limit operator 16 so that the output signal from the detector 14 meeting the balance value corresponding to the permissible value of the final amt. of the refrigerant sticking to the wire rod is obtd. A lower limit operator 16 controls a signal 15 for the set value of the flow rate of the washing water so as not to fall below the lower limit value of the flow rate of the washing water determined by the operating condition. A controller 10 for the flow rate of the washing water controls a control valve 12 by receiving the set signal 15 and the signal from a flow rate detector 11 interposed in the washing water flow passage. As a result, the flow rate is controlled while the limit value of the flow rate of the washing water is maintained under said operating condition by the operator 16.

摘要： PROBLEM TO BE SOLVED: To accurately detect the position and quantity of a wear step of a work roll from its roll profile. SOLUTION: Variation in primary differential value and variation in secondary differential value are found from the measured roll profile to the overall length of the roll profile (steps A2, A3). The multiplication value of the primary differential value and secondary differential value is found to the overall roll profile length (step A4). The primary differential value and the multiplication result in the step A are evaluated from the center position of the roll profile to the right and left end parts, to decide as a wear step start position the position where the primary differential value is larger than a specific threshold, the multiplication result obtained in the step A4 is larger than the specific threshold and as a wear step end position the position where the primary differential value is less than the specific threshold (step A5). The wear step quantity is found as the difference between the roll profile values corresponding to the wear start position and wear end position from the positions.
