摘要:
The invention provides a brushing apparatus hardly affected by metal powder and the cleaning water during the brushing operation and free from damage caused by the contact with the metal strip (P). The brushing apparatus of the invention reciprocates in the width direction of the metal strip (P) with its brush roll stand being controlled by a control unit. The brushing apparatus comprises position sensors (100) for detecting the width direction edges of the metal strip (P), wherein the position sensors (100) are provided with emitting portions (101) each located in a position corresponding to an end of the brush roll for emitting linear flows of water or air, etc. from a side above or below the metal strip (P) to the other side and receiving portions (102) for receiving the linear flows and outputting detection signals to the control unit.

Disclosed are a brush roll and brush elements thereof which are useful for grinding, polishing cleaning or otherwise treating steel sheets, plates or strips. The brush roll and the brush element have in common the following feature. A brush element U comprises an assembly of annular disks 2 joined together as arranged side by side in the direction of width thereof and each having polishing bristles or cleaning yarns 1 implanted in an outer periphery thereof to provide an assembly of such brush elements U as fitted around a shaft 3 and arranged side by side longitudinally of the shaft 3, the brush element U being engageable with the shaft 3 by keyways 5 formed in both a peripheral surface of the shaft 3 and an inner peripheral surface of the brush element U and equidistantly spaced apart circumferentially of the peripheral surfaces and by sunk keys 4 fitting in the respective keyways 5, the sunk keys 4 and the keyways 5 being each so profiled in cross section that the sunk key 4 is prevented from slipping out of the keyway 5a in the brush element U radially of the brush element U, the sunk keys 4 having a length not larger than the length of the brush element U, each of the sunk keys 4 being expandable or contractable widthwise thereof and tightly engageable in the keyway 5 when expanded and disengageable therefrom when contracted, the sunk key 4 being prevented from slipping out of the keyway 5 in the brush element U longitudinally of the keyway by retaining means C when fitted as contracted in the keyway 5.

摘要:
Provided is a strip edge detection device that can precisely detect an edge of a strip, and that can reduce maintenance labor; and also provided is a brushing apparatus comprising the same. An edge detection device 7 reciprocates in a width direction of a strip 2, together with brush rolls 3, to detect an edge of the strip 2 in the width direction. The edge detection device 7 comprises a light-emitting portion 8 for emitting light from one side of the front and back surfaces of the strip 2 to the other side; a light-receiving portion 9 for receiving light emitted from the light-emitting portion 8, the light-receiving portion 9 being placed on the opposite side of the light-emitting portion 8 with respect to the strip 2; multiple covers 100 individually covering the light-emitting portion 8 and the light-receiving portion 9; an air injection means 11 for continuously injecting air to the light-emitting portion 8 or the light-receiving portion 9, the air injection means 11 being provided in each cover 100; and a water injection means 12 for injecting water to the light-emitting portion 8 or the light-receiving portion 9 at a predetermined timing, the water injection means 12 being provided in each cover 100.
摘要:
A steel strip is degreased with low power consumption by subjecting the steel strip to electrolytic washing in a degreasing apparatus including an electrolytic washing apparatus in which electrodes confront each other across the steel strip located therebetween, and charge density and current density are maintained within a predetermined range. There is also provided a simple steel strip degreasing apparatus which is especially suitable for the method.
