摘要： PURPOSE:To perform the adjustment of a shape with good accuracy after predicting the future variation of the shape by deciding the latest target shape data, control gain, etc., based on the shape variation tendency and latest actual shape information and performing the shape adjustment based thereon. CONSTITUTION:In a metal rolling shape adjusting device 1, the actual shape data of elongation and tense detected from the sensor of a roll rolling mill 2 side is stored as well as collected periodically by a sampling means. The variation tendency of the actual shape and latest actual shape information are operated from the actual shape data stored in the sampling means by a shape variation tendency arithmetic means. Moreover the shape is adjusted with good accuracy by adjusting the target shape data to be given to the control gain or shape control part of the case of setting the target shape, based on the variation tendency and latest actual shape information.

摘要： PURPOSE: To execute adjustment at an optional concentration and dispersion degree by collecting an emission at a forward part of a roll stand after finishing of cooling/lubricating performance, individually treating a separated liquid phase and using again as an emulsion. CONSTITUTION: All the mixture of water/mixture of oil flows into a collecting tank below a roll stand 1, and from here is sent into a collecting and separating vessel 22 through an oil/water mixture conduit pipe 37. A separated oil phase is again settled in an oil collecting vessel 53, and then in succession is subjected to purification of metallic components and additional water separation in an oil purification device 41. A water containing oil phase is returned to the collecting and separating vessel 22 as a mixture phase through an introducing conduit pipe 45 so as to be separated. The purified oil is collected in a pure oil vessel 43, and in some cases fresh oil is added from a fresh oil vessel 44. In the fresh oil vessel 44, emulsifier is mixed to control emulsion. The water phase separated in the collecting and separating vessel 22 is purified by a filter 47, is collected in a pure water vessel 48, and over again is settled.

摘要： PURPOSE:To efficiently stabilize a crown of a cold rolling roll by bringing a cooling pattern of a roll coolant to be a flat pattern in the rolling width direction immediately after changing work rolls and increasing or decreasing coolant supply amounts in proportion to rolling speeds. CONSTITUTION:A strip 3 is rolled by upper and lower work rolls 1, 2 and a coolant is supplied from coolant nozzles 4. A coolant controller 5 controls a coolant supply amount. Then, a cooling pattern of the roll coolant is made to be a flat pattern in the rolling width direction for a duration time in which a prescribed number of coils are rolled immediately after changing the work rolls 1, 2. A coolant supply amount is proportioned to a speed detected by a speed detector 7 and the roll coolant supply amount is increased or decreased by use of an process computer 8 and the controller 5. Hence, a crown of the cold rolling rolls is efficiently stabilized.

摘要： PURPOSE:To quicken a response time constant for coolant controlling and to improve the shape control accuracy by making the region having a large influence coefficient a coolant control range. CONSTITUTION:The flow rate range causing large crown changes is made to be the coolant control range and its nearly central value is to be a setting value. A control computing element 22 outputs a control value into a coolant controller 26 to control the coolant flow rate within the coolant control range based on the shape deviation. Therefore, the coolant controller 26 controls the coolant flow rate within the coolant control range. By this method, the control time constant is quicken to be able to follow the thermal crown change of the roll sufficiently. Therefore, the controlling is enabled following to the crown change of the stock to be rolled, the accurate shape control is made possible.

摘要： PURPOSE:To perform cooling control for rolling rolls by a prescribed cooling capacity in spite of variations in a water film thickness by detecting surface temps. of rolling rolls and adjusting volume of a cooling water supplied to cooling water jackets. CONSTITUTION:Surface temps. of rolling work rolls 2 detected by temp. measuring means 4 and shown on a temp. indication panel 10 are monitored by an operator; the operator adjusts a variable throttle valve 7 to control volume of a water supply with the operator watching a flow meter 9. As the result, the roll surface temps. of the rolls 2 during rolling are properly controlled. The operational efficiency is improved because setting a water film thickness is not needed to be so severe.

摘要： PURPOSE:To rapidly remove local defects in flatness and to obtain a product having good flatness by controlling injection from coolant nozzle headers based on flatness detection results in plural roll coolant control regions segmented in the width direction of a strip. CONSTITUTION:A 1st coolant injection deciding means 31 and a 2nd coolant injection deciding means 32 are installed in the output side of a flatness deviation computing element 24. The element 24 calculates a deviation value of an actual detected flatness value found by a shape detector 22 from a previously decided target value. The deviation value is converted into a flatness deviation value corresponding to zone segmentation of coolant nozzle headers 20. The 1st means 31 processes the flatness deviation value to output a 1st coolant flag. Also, the 2nd means 32 processes the deviation value to output a 2nd coolant flag. Both the flags are inputted to a 3rd coolant injection deciding means 33 to output a coolant open-and-close signal for each coolant injection solenoid valve 21 decided as a logical sum.

摘要： PURPOSE:To obtain a simple, practical, and easy adjustable control system by deciding a gain in shape feedback control as a function of a deviation in work roll diameter, sheet width, position of an intermediate roll. CONSTITUTION:A shape of a rolled stock 5 passed through a work roll 1 of the final stand is detected by a shape detector 6 of magnetic correlation system, etc., and the shape data is inputted to a shape feedback controller 7. The controller 7 converts a shape measured value into a parameter and decides a gain by a formula expressing the gain as a function of a deviation in work roll diameter, sheet width, and shift position of an intermediate roll. Then, required control amounts such as thermal crown, roll bender, etc., are decided by substituting both a difference between a measured shape parameter and a target shape parameter and a gain into the formula to perform calculation. The thermal crown is further converted into a pattern of a roll coolant and all the total operation amounts at an operation end 8 and decided.

摘要： PURPOSE: To minify a body and make it slim and lower a seat height and ensure a storing capacity by arranging a storing box upheaving upward and provided with an opening in a frontside at the rearside of a seat rear end and covering a backseat to the opening openably/closably. CONSTITUTION: In the rear part 14b of a body cover formed by upheaving upward on the rearside of a backseat 4, an opening 18 is opened on its frontside and the opening 18 is covered by a seat 4. The upper end rear surface of the seat 4 is pivoted by a hinge 19 and it can be opened upto an upright position toward a front upper side and at the closed time, the lower end of the seat 4 is set so as to be overlapped to the rear end upper surface of a seat 3. A box 24 whose opening 18 is common is arranged in the rear part 14b and the box 24 is inserted in a double structure while holding an auxiliary frame 7 and supported to a bracket 25 striding over the frame 7. Therefore, the box 24 can be set to the bigness sufficient to store a helmet and a body can be made slim as some rooms are formed in the space of the cover front part 14a and the seat height can be constructed to a desired height.
