Description

Verfahren und Vorrichtung zur Behandlung von Blechen zwecks Entfernung der Unreinlichkeiten und zur Erzielung einer gleichmäßigen Härte. Den Gegenstand der Erfindung bildet ein Verfahren--und eine Vorrichtung zur Behandlung von Blechen zwecks Entfernung der Unreinlichkeiten und zur Erzielung einer gleichmäßigen Härte. Es sind bereits Verfahren bekannt, Drähte und Bänder in einem Arbeitsgange zu bürsten, zu beizen und zu spülen. Bei dem vorliegenden Verfahren handelt es sich darum, Bleche, die zum Schweißen verwendet werden und die aus verschiedenen Erzeugungsstätten herrühren, die also ungleichmäßig gehärtet sind, auf eine gleichmäßige Härte zu bringen. Dies geschieht dadurch, daß in einem Arbeitsgange die Bleche gereinigt und darin der Einwirkung geheizter Preßw alzen, Preßplatten usw. unterworfen werden.Method and device for treating sheet metal for removal the impurities and to achieve a uniform hardness. The subject of the invention forms a method - and an apparatus for treating sheet metal to remove the impurities and to achieve a uniform hardness. There are already methods known to brush wires and strips in one operation, to pickle and rinse. The present process involves the removal of metal sheets, which are used for welding and which come from different production sites, that are unevenly hardened to bring them to a uniform hardness. this happens because the sheets are cleaned in one operation and the The action of heated press rolls, press plates, etc. are subjected.

Auf der Zeichnung ist schematisch eine Vorrichtung gemäß der Erfindung dargestellt. Die zu reinigenden Bleche a werden durch eilten mit Beizflüssigkeit gefüllten Kasten b geführt, gebeizt und dann von Hand oder auf mechanischem Wege durch Abstreifer c hindurchgeführt, wo die Beizflüssigkeit entfernt wird. Die Bleche werden von den Transportwalzen d aufgenommen und durch den Führungskanal e transportiert. Beim Durchgang durch denselben werden die Bleche durch umlaufende Bürstenwalzen f von beiden Seiten gereinigt. Die Bürsten«alzen treten durch Aussparungen des Kanals e dur h und die Bleche werden nach dem Abbürsten von Transportwalzen g wieder aufgenommen und durch einen Führungskanal h in den mit Spülwasser versehenen Kästen i befördert. Das Wasser wird durch die Abstreifer j abgestrichen und die Bleche dann .durch beheizte Walzen k, welche das noch anhaftende Wasser verdampfen, befördert. Beim Austritt aus 'den Walzen k werden- die Bleche noch durch einen mit Stoff ver:-eLenen Abstreifer hindurchgeführt, damit der letzte evtl. noch anhaftende feuchte Hauch dadurch genommen wird.In the drawing is a device according to the invention schematically shown. The sheets to be cleaned a are rushed through with pickling liquid filled box b out, pickled and then by hand or by mechanical means passed through scraper c, where the pickling liquid is removed. The sheets are picked up by the transport rollers d and transported through the guide channel e. When passing through the same, the sheets are moved by rotating brush rollers f cleaned from both sides. The brushes roll through recesses in the channel e through h and the sheets are picked up again after being brushed off by transport rollers g and conveyed through a guide channel h into the boxes i provided with washing water. The water is wiped off by the scraper j and the sheets are then heated by Rollers k, which evaporate the still adhering water, conveyed. When leaving from the rollers k the metal sheets are still covered by a scraper covered with fabric passed through, so that the last possibly still adhering moisture breath is removed will.

Die Walzen k haben eine Temperatur von ungefähr ioo°. Die Bleche erhalten durch diese Behandlung eine gleichmäßige Härte. Die behandelten Bleche können sofort -weiter verarbeitet werden. Die so behandelten Zinkbleche ergeben insbesondere beim Schweißen keinen Ausschnß. Auch werden erfrorene Zinkbleche durch die geschilderte Behandlung wieder brauchbar.The rollers k have a temperature of approximately 100 °. Received the sheets this treatment gives it a uniform hardness. The treated sheets can be used immediately - further processed. The zinc sheets treated in this way result in particular in Do not weld any cutouts. Also frozen zinc sheets are caused by the above Treatment usable again.
