摘要： PURPOSE:To shorten measuring time and to shorten the total rolling time as long as the measuring time by operating using an estimated roll profile in place of a measured roll profile during measuring pitch. CONSTITUTION:In the case that the roll profile is measured with a roll profile detector, a grinding roll profile is determined from the difference between the measured roll profile and the target roll profile in a roll grinding amount arithmetic device 26 and roll grinding is executed. On the other hand, the measured roll profile is switched to an predicted roll profile that is operated with an estimated roll profile arithmetic device 31 with a switching device 33 during the measuring pitch, the grinding roll profile is determined from the difference between the predicted roll profile and the target roll profile in the roll grinding amount arithmetic device 26 and roll grinding is executed. In this way, measuring time is shortened and, since the predicted roll profile is used, roll wear that is developed by rolling during grinding is taken into consideration.

摘要： PURPOSE:To hold at a target roll profile where the shape of a product plate is made optimum by providing a roll profile arithmetic controller, determining the optimum pressing position of a grinding wheel and changing a grinding position. CONSTITUTION:The roll profile arithmetic controller 29 is provided in a on-line roll grinder device. The roll profile to be ground, which is a difference between a roll profile actually measured with a detector 11 and the target roll profile which is arithmetically processed to become the optimum roll profile, is divided for each oscilater of the grinding wheel 10; an intersected point with a grinding profile is determined and a grinding section is decided. The mid point between the intersected point and the maximum wear point in an ungrinding section is made a position to start or finish the grinding; an optimum position to press the grinding wheel is determined for each oscilater; and also the grinding position is changed. Thus, the difference between the roll profile after grinding and the target profile is reduced.

摘要： PROBLEM TO BE SOLVED: To apparently increase the lateral rigidity of a housing and to suppress vibration by connecting them between the housings of a rolling mills which are arranged in tandem with support beams in the direction of the pass line. SOLUTION: On the pass line PL of a steel sheet of the housings H of the rolling mills, one support beam 2 is provided. The number of the beam 2 is optional in the range of the space allowed. The cross-sectional shape of the beam 2 is not cared, but it is required that bending and compressive rigidities are same as or more than the rigidity in he direction of the pass line. By providing the support beam 2 of a steel pole having the diameter of 500 mm, for example, between the housings H having the rigidity of 220 tonf/mm in the direction of the line, the rigidity of the housing H in the direction of the pass line is increased by 1.5 times. At this time, simultaneously, the frequency of the natural vibration of the housing in the direction of the pass line is increased by square-root times of 1.5 from 50 to 61 Hz, the damping ratio is also increased by 1.5 times from 5 to 7.5% and the vibration of large amplitude is not generated.

摘要： PROBLEM TO BE SOLVED: To take up a steel strip in a hot rolling equipment in a normal condition. SOLUTION: When a strip is coiled around a mandrel 10, the outer diameter of the mandrel 10 is firstly expanded to the same dimension as the inner diameter of a coil 40a, and in the second and subsequent coiling, the control is realized to avoid steps and the mandrel 10 is finely expanded. When the prescribed coiling number is reached, the diameter of the mandrel 10 is secondarily expanded to press the inner surface of the coil 40a, the lead ratio of the mandrel 10 is reduced to reduce the necking quantity of the strip. The frequency in controlling the step avoidance is reduced by releasing the control to avoid the step at early stage, and the friction of a segment 4 of the mandrel 10 and a unit roller is reduced to coil the strip in a normal condition.

摘要： PURPOSE:To detect the snaking amount and the width of a strip-shaped material accurately and stably by providing a pair of mounts, a pair of three-dimensional image sensing devices, purging devices, an image processing device, and an operating device. CONSTITUTION:Mounts 13 and 13 have moving means for movement in the width direction of a strip-shaped material. Three-dimensional image sensing devices 18 and 18 using optical cameras 18a and 18b and 18c and 18d accommodate both edge parts of the strip-shaped material 11 in the direction of the width in the fields of view. Purging devices 22 and 22 always purify the fields of view of the three-dimensional image sensing devices 18 and 18 effectively. An image processing device 20 computes the edge positions in the fields of view of the cameras based on the image signals from the cameras. An operating device 17 computes the two-dimensional position coordinates of the edge positions in the direction of the height and the direction of the width based on the edge positions by a triangulation method. The snaking amount or the width of the strip-shaped material is computed based on the position coordinates of both edges and the position coordinates of the mounts. In this way, the snaking amount and the width of the strip-shaped material can be detected accurately without the effects of up and down movement and the inclination of the strip-shaped material.

摘要： PURPOSE:To detect a plate turning angle automatically and to automate a plate turning device by using a plate turning angle theta or the other plate turning angle (90-theta) from the point of time the turning angle theta exceeds 45 deg. after the start of turning. CONSTITUTION:A television camera detecting infrared light emitting from a plate scans on a roll. The plate width on every optional DELTAN pitched scanning lines is detected sequentially. A plate turning angle theta is obtained based on an increment or a decrement of the plate width between every the number of optional scanning lines n.DELTAN. The time when that theta reaches or exceeds the value of (45-DELTAtheta) is monitored as necessary. When an operation such as braking is needed so early before that time elapses the operation is performed referring to the turning angle theta. After the theta exceeds the cross point A is detected, the turning angle of (90-theta) is used as an actual turning angle, where, the theta is a measured value. A timing of an operation such as braking is planed based on the value of (90-theta).

摘要： PURPOSE:To reduce the cost of production as well as to prevent the occurrence of trouble from the standpoint of control, by attaching a vibro-detector to a servo valve, while inferring a deteriorating state of the servo valve from a variation in the vibration level detected by this vibro-detector. CONSTITUTION:A vibro-detector 6 is installed in a servo valve 4, while output out of this vibro-detector 6 is inputted into a vibration analyzer 9, and a deteriorating state of the servo valve 4 is inferred from a variation in a vibration level. With this constitution, vibrations due to a leak of oil in the servo valve 4 is always monitored and thereby a durable limitation in the servo valve 4 is knowable so that service duration of the servo valve 4 is prolongable and, what is more, manufacturing cost is reducible. In addition, any trouble from the standpoint of control due to deterioration of the servo valve 4 is preventable before it happens.
