摘要： PURPOSE:To surely execute rolling reduction support for a cast slab by arranging control valves respectively to cylinders for rolling reduction and for shifting of the cast slab and arranging change-over means for cutting-off between a controller and the control valve for the shifting cylinder. CONSTITUTION:Servo valves 49a, 49b, 49c, 49d are arranged respectively to the cylinders 44, 42 for rolling reduction and the cylinder 19, 28 for shifting of the cast slab. A discriminator 46 inputting the velocity Vcc of the cast slab is connected with a controller 48 through shifting velocity computing element 47. Further, the controller 48 is connected with the servo valves 49a, 49c and the change-over switches 52b, 52d are arranged between the controller 48 and comparators 51b, 51d. As the same way, the change-over switches 53b, 53d, 55b, 55d are respectively arranged. When the sending velocity of the cast slab is less than the lower limit velocity Vccd, working of the cylinders 19, 28 at the time of rolling reduction is cut off. By this method, the damage of the device is prevented and the cast slab is surely supported to the rolling reduction.

摘要： PURPOSE:To uniformize rolling reduction to a cast slab by arranging a computing element of elastic deforming rate of a bar for the cast slab rolling reduction and a correcting computing element for the cast slab rolling reduction rate and controlling a cylinder for rolling reduction based on difference between the correcting rolling reduction rate and the aimed rolling reduction rate. CONSTITUTION:Load detectors 35, 40 are arranged between the cylinders 26a, 26b for rolling reduction and a hausing, and a detector 35 is connected with a ground detector 36 and a computing element 41. The detector 40 is connected with the computing element 41 and also the computing element 41 is connected with an elastic deforming displacement rate computing element 42, and further, computing elements 34, 42 are connected with a computing element 43. By this method, the total load variation p is found with the computing element 41 and the difference y with the aimed value for the rolling reduction rate is operated with the computing element 34. Further, under consideration of the elastic deforming rate y' of bar units 10, 10', the cylinders 26a, 26b for rolling reduction are controlled. As the rolling reduction control is executed by operating the deforming rate y' of the bar unit 10, 10', the rolling reduction is accurately and uniformly executed to the cast slab.

摘要： PURPOSE:To restrain the development of unnecessary reaction to a cast slab by arranging a detector for depressing load and a dislocation meter for sending cylinder in the continuously cast slab depressing supporting device and controlling the cylinder so that the sending speed in range of approach running of the bar sending movement becomes the advancing speed of the cast slab. CONSTITUTION:In sending movement of an inner and outer bars 13, 12 in the continuously cast slab depressing supporting device, the dislocation in the range R of the approach running is measured by the dislocation meter 32, and the sending cylinders 27, 28 are controlled through a controller 33 so that the sending speed becomes the advancing speed of the cast slab 3. Then, period P of the cast slab depressing with the bars is detected by a load cell 29 and output of the cylinders is controlled corresponding to the depressing force and holding of the cast slab 3 is released at the range S. By this method, the development of unnecessary reaction in the cast slab 3 can be prevented.

摘要： PURPOSE:To detect depressing rate at the prescribed position and to control the depressing so as to be the prescribed depressing rate by arranging inner and outer bar unit at every line and arranging a cast slab depressing device supporting so as to possible to contact with/detach from the cast slab. CONSTITUTION:The depressing device 7 constituting of inner and outer bar blocks 8, 9 holds the cast slab 3 and the bar blocks 8, 9 are shifted together with the cast slab 3 to support so as to be possible to contact with/detach from the cast slab 3. By the outer bar depressing cylinder 44, the depressing force of the bar unit is detected with the pressure detector 51. The control device is composed of a positioning sensor 45, comparison computing element 46, correction operating unit 48, etc. The comparison computing element 46 calculates actual depressing rate based on the setting value, output of depressing dislocation after grounding from the comparison adder 57 and output from the correction computing element 48. In case of existing excess or shortage against the depressing rate, servo-valve 49 is worked and corrected to the prescribed depressing rate.

摘要： PURPOSE:To substantially execute rolling reduction only to non-solidified layer in a cast slab, to reduce the rolling reduction force by half and to stabilize inner quality of the cast slab by arranging rolling reduction liner to be possible to change into contacting state or non-contacting state with the cast slab surface at contacting part of an inner and an outer bars with the cast slab positioning at both sides to width direction of the cast slab in the title device. CONSTITUTION:At the time of executing the rolling reduction of the cast slab 3, cylinder 32 in the outer bar 12 or further the inner bar 13 positioning to the whole width part of solidified layers 6 at both sides is worked in accordance with the width size of the cast slab 3. In this result, the rolling reduction liner 29 connecting with the cylinder 32 is shifted to the outer bar 12 and the inner bar 13 along dovetail grooves 30. In this case, as the reverse tapered face having inclination in the groove 30 is formed, the contacting face of the liner 29 with the cast slab is made to non-contacting state to the surface of the cast slab 3. Under this condition, at the time of executing the rolling reduction of the cast slab 3, as the rolling reduction is executed to the non-solidified layer 2 at the center of the cast slab 3 contacting with the liner 29 and is not executed to the non-contacting solidified layer 6 at both sides of the cast slab 3, the rolling reduction is executed only to the layer 2, and as the rolling reduction force needed at this time is very little, load to the equipment can be drastically reduced.

摘要： PROBLEM TO BE SOLVED: To predict the time when a roll is broken due to a bearing of the roll in a continuous casting apparatus. SOLUTION: A roll gap measurement device installed on a dummy bar 1 passing through a cast piece passage of the continuous casting apparatus previously measures the gap between oppositely provided rolls 4 and 5 at a plurality of times with time interval. The time-series tendency of the difference between the measured result and a reference value is checked, and the time period when the difference becomes not less than a predetermined value is estimated based on the time-series tendency of last time, and the time period is determined to be the time of breakage of the roll. Thus, the rolls can each be replaced before breakage of a bearing. COPYRIGHT: (C)2010,JPO&INPIT
