Description
Die Erfindung betrifft neuartige Transportrollen in Transportsystemen für Glaskeramikplatten.The invention relates to novel transport rollers in transport systems for glass ceramic plates.
Heiße, aber schon spröde Glasbänder werden z.B. nach dem Floaten und Walzen vorwiegend mittels Rollensystemen transportiert. Hot, but already brittle glass ribbons are mainly transported by means of roller systems, e.g. after floating and rolling.
Man verwendet dabei als Rollenmaterial vorzugsweise Asbest. (GB-PS 1421384). Der Asbest wird dabei in Form von runden Platten mit einer zentrischen Bohrung auf den Rollenträger geschoben, zusammengepreßt und verankert, und anschließend wird der Astestteil der Rolle rund gedreht. Die auf der Glastafel gegebenenfalls zurückbleibenden Asbestreste können später von der kalten Oberfläche abgewischt werden. Bleiben trotzdem kleine, unsichtbare Mengen von Asbestbestandteilen . an der Glasoberfläche haften, so stören sie im allgemeinen nicht.Asbestos is preferably used as the roll material. (GB-PS 1421384). The asbestos is in the form of round plates with a central hole pushed onto the roller carrier, pressed together and anchored, and then the branch test part of the roll is turned round. Any remaining on the glass panel Asbestos residue can later be wiped off the cold surface. Still small, invisible ones Amounts of asbestos components. adhere to the glass surface, they generally do not interfere.
Beim kontinuierlichen Walzen von Glaskermik kann Asbest als Material für die Rollenoberfläche nicht verwendet werden, weil die nicht entfernbaren Reste beim Keramisieren (Umwandlung des Ausgangsglases in die Glaskeramik) eindiffundieren und die Endfestigkeit unzulässig stark herabsetzen würden.When continuously rolling glass ceramics, asbestos cannot be used as the material for the roll surface, because the non-removable residues diffuse in during ceramization (conversion of the starting glass into the glass ceramic) and would reduce the final strength to an inadmissible extent.
Es ist auch bereits vorgeschlagen worden (DE-PS 25 33 367), zum Überziehen von Transportrollen für heiße Glasbänder schlauchförmige Hüllen aus einem Gewebe aus hoch hitzebeständigen Fasern, wie beispielsweise Quarzglasfasern zu verwenden. Beim Walzen von Glaskeramik verbietet sich auch die Verwendung von Quarzglasgewebe, weil bei den herrschenden hohen Temperaturen die Abrieb- und Bruchfestigkeit zu stark herabgesetzt wird und ein häufiges Auswechseln erforderlich ist; der dadurch verursachte Auf-It has also already been proposed (DE-PS 25 33 367) for covering transport rollers for hot glass ribbons tubular sheaths made of a fabric made of highly heat-resistant fibers, such as quartz glass fibers use. When rolling glass ceramics, the use of quartz glass fabric is also prohibited because the The prevailing high temperatures the abrasion and breaking strength is reduced too much and frequent replacement is required; the resulting increase
wand ist unvertretbar groß. Ziel der Erfindung ist daher eine neuartige Transportrolle, welche auch für den Transport heißer Glaskeramikscheiben geeignet und darüberhinaus preiswerter und dauerhafter als herkömmliche Rollen ist. Dieses Ziel wird erfindungsgemäß mit einer Transportrolle erreicht, deren die Glaskeramikscheibe tragende Oberfläche dadurch gekennzeichnet ist, daß sie aus einer Lage aus Stahlwolle besteht.wall is unacceptably large. The aim of the invention is therefore a new type of transport roller, which is also suitable for transporting hot glass ceramic panes and beyond is cheaper and more durable than conventional rollers. This goal is achieved according to the invention with a transport roller achieved, whose surface carrying the glass ceramic panel is characterized in that it consists of consists of a layer of steel wool.
Stahlwolle ist ein Material, das durch Zerfrasen von Metallstäben entsteht, zu Rovings verknäuelt wird und in Form von Kissen als Topfreiniger verwendet wird. Für die Verwendung auf Transportrollen für heiße Glasbänder wäre Stahlwolle ungeeignet, und ein derartiges Vorurteil bestand insbesondere für die Verwendung von Stahlwolle auf Transportrollen für heiße Glaskeramikbänder. Es hat sich jedoch überraschend gezeigt, daß beim Walzen von Glaskeramik die von der Transportrollenoberfläche herrührenden Defekte an den Scheibenoberflächen bei der weiteren Behandlung dieser Scheiben wieder ausheilen.Steel wool is a material that is made by milling Metal rods are created, twisted into rovings and used in the form of pillows as a pan cleaner. For the Steel wool would be unsuitable for use on transport rollers for hot glass ribbons, and such a prejudice existed especially for the use of steel wool on transport rollers for hot glass ceramic tapes. It has, however Surprisingly shown that when rolling glass ceramic, the defects originating from the surface of the transport roller occur the disc surfaces heal again during the further treatment of these discs.
Die Stahlwolle kann auf der Transportrolle in beliebiger, geeigneter Weise befestigt werden. Die bevorzugte Methode der Aufbringung der Stahlwolle besteht darin, einen endlosen Strang aus Stahlwolle auf die Rollenoberfläche aufzuwickeln. The steel wool can be attached to the transport roller in any suitable manner. The preferred method The application of the steel wool consists in winding an endless strand of steel wool onto the roll surface.
Zweckmäßigerweise besteht die erfindungsgemäß zu verwendende Stahlwolle aus hitze- und oxidationsbeständigem Stahl.Appropriately there is that to be used according to the invention Steel wool made from heat and oxidation resistant steel.
In der Zeichnung ist eine Transportrolle gemäß der Erfindung dargestellt. Auf eine Transportrolle herkömmlicher Bauart ist eine Lage aus Stahlwolle aufgewickelt.In the drawing, a transport roller according to the invention is shown. Conventional on a transport roller The construction is a layer of steel wool rolled up.
