Abstract: PURPOSE:To improve the accuracy of weight of a cast slab by grasping the variation of thickness of the cast slab by actual measurement or surface temp. measurement and finding the prescribed cutting length from the aimed weight and the variation of thickness for the cast slab. CONSTITUTION:A correlation between the surface temp. and the weight ratio of the cast slab is extremely high and the weight ratio reduces as the surface temp. becomes higher. At the time of casting the cast slab in the continuous casting machine, the thickness of the cast slab is actually measured at the downstream side of pinch roll or the surface temp. of the cast slab is measured at the pinch roll zone and the results are respectively inputted into a controlling device. In the controlling device, variation of the weight caused by variation of the thickness of the cast slab is corrected, so that the slab weight coincides with the prescribed value, and the variating quantity is calculated to find the prescribed cutting length. Or, the prescribed cutting length is found based on the relation between the surface temp. measured value and the weight ratio. As the variating quantity for the weight is compensated by correction of the cutting length of the cast slab, the accuracy of weight of the cast slab is improved.

The coal delivery quantity Q is computed from the differential pressure DELTAP between the detected primary air pressures P1, P2 in a coal delivery quantity computing device 27. The coal delivery quantity deviation DELTAQ is determined by detecting the difference between the computed coal delivery quantity Q and the set coal delivery quantity Q0 corresponding to the boiler load command M in a substracter 29. The vane opening degree command X is determined from the coal delivery quantity deviation DELTAQ in a proportional integral controller 30. The vane opening degree of the separating vane 13a of the classifier 13 is so adjusted by this vane opening degree command X that the coal delivery quantity deviation DELTAQ attains zero. Consequently, the coal delivery quantity from the vertical mill is exactly controlled.

Title: Opening control device for motor-operated expansion valve
IPC: F15B21/00
Filed: 1992-03-10
Abstract: PURPOSE:To prevent the occurrence of defective setting due to instantaneous power stop when a motor-operated expansion valve is closed to set an opening to a reference value. CONSTITUTION:A motor-operated expansion valve 8 is arranged in a refrigerant circuit 14. A control part 130 connected to a first power source Tr1 and a drive part 120 connected to a second power source Tr2 are provided. When instantaneous power stop is detected during closing of the motor-operated valve 8 by means of a valve closing command means 201, the number of pulses of a closed valve is increased and corrected according to an outage time or by a specified amount by means of a correcting means 201. This constitution corrects an error between a control signal and a valve closing drive amount owing to a difference in responsiveness to power stop between the power sources Tr1 and Tr2 and prevents defective setting of the motor-operated valve 8 to a reference opening. When power stop occurs during thermo-ON operation, similar correction is executed when a valve opening is set to a reference opening.
