摘要： PROBLEM TO BE SOLVED: To make a chamber preventing device in a rolling mill compact, and improve the quality of rolled material and production efficiency by shorten ing the distance from a rolling machine to a descaling header and HMD when reversing rolling mill is applied. SOLUTION: A camber preventing guide 9 is arranged with a ctenoid end 9b and a rear stripper guide 8b lapped together, and set up possible to move rotatably because of a preventing camber guide's rotatably moving axis 18b fixed on the same axis with a rear stripper guide's rotatably moving axis 18a. The width of a preventing camber guide 9 itself is made shorter than a rear stripper guide 8's width (or a maximum rolled plate's width). Two pieces of preventing camber guide's cylinder 21 are fixed facing each other across an oil pressure cylinder 19 attached to a rear stripper guide 8 against a camber preventing guide 9, each of an exit part of a camber preventing guide 9 and a rear stripper guide 8 is independently controlled moving rotatably.

摘要： PURPOSE:To improve the property and quality of the surface of product by varying/rationalizing the lubricating condition of up and down sides of vertically symmetrically hot rolled strip. CONSTITUTION:When strip rolling is executed with a vertically asymmetric hot rolling mill 7 of which the upper and lower work rolls between which the strip 3 is held are intentionally provided with a stepped part, lubricants with different lubrication property are respectively supplied to the upper and back sides of the strip 3 and also the rolling bite possible condition for every strip is calculated. In the case that condition isn't satisfied, the supply of lubricant is stopped at least at the time of biting with the rolling mill. In this way, the small diameter roll can be prevented from friction and surface roughening and, without reducing the quantity of scheduled rolling with the slip at the time of biting, furthermore, high draft rolling and high speed rolling can be executed and rolling efficiency can be improved.

摘要： PROBLEM TO BE SOLVED: To easily measure a vibration acceleration of a cage at low cost when machinery facilities are operated. SOLUTION: Vibration acceleration detectors 40 and 41, and 44 are mounted on the cage 26 and a bearing box 30, respectively. By hitting the shaft 20 when the machinery facilities is stopped, the vibration acceleration of the holder 26 and the vibration acceleration of the bearing box 30 during the standstill period of time are measured, respectively, to obtain the relationship between both the measurement values in advance. Thereafter, the vibration acceleration of the bearing box 30 is measured when the machinery facilities are operated, and the vibration acceleration of the holder 26 during the operating period of time is found from the measured value during the operating period of time and the relationship between both the measured values during the standstill period of time. Further, the driving speed of the machinery facilities is decelerated or stopped, according to the thus obtained vibration acceleration and the permissible vibration acceleration.

The injection flow passage 2 and an introducing flow passage 4 are communicated and connected in the back and forth direction of the diametral direction of the infection flow passage 2 clamping the valve hole 17. A valve seat 19 is formed at the front end face of a valve hole forming member 13 and many slit flow passages 20 are formed at the base part of this valve hole forming member 13, by which the filter 21 of the high-pressure water flowing into the injection flow passage 2 is constituted. A valve seat fitting 14 and a plug 15 are freely attachably and detachably screwed to both ends of the valve body 16 to make both ends of the valve body 16 freely openable and closable. As a result, the filter 21 is made freely attachable and detachable.
