Description
Anordnung zum Messen magnetischer Eigenschaften an einem bewegten Elektroblechband Die Erfindung bezieht sich auf eine Anordnung zum Messen magnetischer Eigenschaften an einem bewegten, eine Walzenstraße unter Zugspannung durchlaufenden Elektro.blechband mit Hilfe eines Magnetisierungsjoches. Arrangement for measuring magnetic properties on a moving one Electrical steel strip The invention relates to an arrangement for measuring magnetic Properties on a moving roller train running under tension Electrical sheet metal strip with the help of a magnetizing yoke.
Es ist bekannt, magnetische Eigenschaften an einem bewegten Band aus Elektrobiech zu messen, wenn dieses ein für die Messung dienendes Magnetisierungsjoch durchläuft. Es is.t ferner bekannt, die magnetischen Eigenschaften von Elektrobiechen in demjenigen mechanischen Spannungszustand zu messen, dem es bei der technischen Verwendung unterliegt, da der mechanische Spannungszustand die magnetischen Eigenschaften des Bleches beeinflußt. It is known to have magnetic properties on a moving belt to measure from Elektrobiech if this is a magnetization yoke serving for the measurement passes through. It is also known the magnetic properties of electrical bending to be measured in the mechanical stress state that occurs in the technical Subject to use because the mechanical stress state has the magnetic properties of the sheet affects.
Demgegenüber besteht die Erfindung darin, daß bei einer Anordnung der eingangs bezeichneten Art Mittel vorgesehen sind, die das Band in einer zugspannungsfreien Schleife das Joch im Sinne der Erzielung gleichbleibender Meßverhältnisse passieren lassen. In contrast, the invention consists in that in an arrangement of the type indicated at the outset, means are provided that the tape in a tension-free Loop the yoke in order to achieve constant measurement conditions permit.
Um eine spannungsfreie Bandstrecke zu erhalten, kann man ein angetriebenes Zubringerwalzensystem und ein bremsendes Abzugwalzensystem, zwischen denen die Schleife gebildet wird, miteinander starr kuppeln. Wenn man an der Anordnung eine Bremsvorrichtung vorsehen will, empfiehlt es sich, die Bremse an einer Abzugwalze anzubringen' Durch dir ses Mittel trägt man dazu bei, die Bandschleife selbst von allen Zugspannungen freizuhalten. Es kann günstig sein, die Zubringerwalzen oder die Abzugwalzen mit einem die. Haftung des Bandes an der Walzenoberfläche vergrößernden Belag, beispielsweise aus Naturgummi, Kunstgummi oder einem anderen Maserial, zu versehen. In order to obtain a tension-free belt section, you can use a driven one Feed roller system and a braking take-off roller system, between which the loop is formed, rigidly couple with each other. If you have a braking device on the arrangement If you want to provide, it is advisable to attach the brake to a take-off roller This means you are helping to keep the belt loop itself from all tension to keep clear. It can be advantageous to use the feed rollers or the take-off rollers one the. Adhesion of the tape to the roll surface enlarging covering, for example made of natural rubber, synthetic rubber or another maserial.
Zur Erläuterung der Erfindung dient die Zeichnung. The drawing serves to explain the invention.
Diese zeigt ein von links her aus der Walzenstraße ankommendes Elektroblechband 1. Dieses wird über mehrere angetriebene Zubringerwalzen 2 und Umlenkwalzen oder Führungswalzen 3 in das Magnetjoch4 eingeführt, welches beispielsweise für sich mit Walzenpaaren 5 und 6 ausgestattet ist, die den magnetischen Kraftfluß vom Magnetjoch auf das Blech übertragen. Am Ende des Magnetjoches 4 ist ein Führungsrollenpaar 7 vorgesehen, und von diesem aus läuft das Band über Umlenkwalzen 8 und Abzugwalzen 9 ab. In der Figur ist ferner angedeutet, daß die Zubringerwalzen 2 und die Abzugwalzen 9 untereinander durch einen Riemen- oder Kettenzug 10 oder durch eine andersartige starre Kupplung, die an Stelle des Riemenzuges angebracht i.st, starr miteinander gekuppelt sind, so daß die Zubringerwalze 2 stets dieselbe Geschwindigkeit hat wie die Abzugwalze 9. Auf diese Weise wird die Bandschleife zwischen der Zubringerwalze 2 und der Abzugwalze9 vom Zug der Aufwickelhaspel, welche am Bandendela zieht, von der Schleife selber ferngehalten. Bei den Abzugwalzen 9 sind ferner Bremsvorrichtungen 11 und 12 vorgesehen, durch die man einen übergroßen Zug oder eine zu große Bandgeschwindigkeit abbremsen kann.This shows an electrical steel strip arriving from the left from the rolling mill 1. This is driven by several feed rollers 2 and guide rollers or Guide rollers 3 introduced into the magnet yoke 4, which for example for itself is equipped with roller pairs 5 and 6, which the magnetic flux from the magnet yoke transferred to the sheet. At the end of the magnetic yoke 4 is a pair of guide rollers 7 is provided, and from there the belt runs over deflection rollers 8 and take-off rollers 9 from. In the figure it is also indicated that the feed rollers 2 and the take-off rollers 9 among each other by a belt or chain hoist 10 or by some other type rigid coupling, which is attached in place of the belt pull, rigidly with each other are coupled so that the feeder roller 2 always has the same speed as the take-off roller 9. In this way, the belt loop between the feed roller 2 and the take-off roller9 from the train of the take-up reel, which pulls on the Bandendela, from the Loop itself kept away. The take-off rollers 9 are also braking devices 11 and 12 provided, by which one an oversized train or an excessive belt speed can slow down.
Es ist zweckmäßig, bei beiderseits spannenden Ablauf-und Aufwickelvorrichtungen der Bandstraße diese Bremsvorrichtung nur am Ende der Schleife des Bandes vorzusehen, nicht aber auch am Anfang, damit auch durch die Abbremsung des Bandes keine Zugspannung auf das Band übertragen werden kann. Die Schleife kann im Arbeitsgang hinter der Walzenstraße angeordnet sein. Die Walzen 5 und 6 im Meßjoch können nach einem bereits an anderer Stelle ausgesprochenen Vorschlag wegen der sonst auftretenden Wirbelstürme aus Blechseheiben geschichtet oder aus magnetisierbarem oder mit einem Isolierübezug versehenen Pulver geformt sein.It is useful if the unwinding and winding devices are exciting on both sides the belt line to provide this braking device only at the end of the loop of the belt, but not at the beginning either, so there is no tensile stress due to the braking of the belt can be transferred to the tape. The loop can be used behind the Be arranged roller train. The rollers 5 and 6 in the measuring yoke can after one already Suggestion made elsewhere because of the hurricanes that would otherwise occur layered from sheet metal disks or from magnetizable or with an insulating cover provided powder be shaped.
