Die Erfindung betrifft ein Verfahren zur Beschichtung von Walzmaterial, insbesondere von Stahlband, mit nichtmetallischen Überzügen, insbesondere Kunststoff, wobei das Überzugsmaterial in flüssiger Konsistenz auf das Walzmaterial aufgetragen und unter Ausnutzung von dem Walzmaterial zugeführter Wärme getrocknet und gegebenenfalls eingebrannt wird»The invention relates to a method for coating Rolled material, in particular of steel strip, with non-metallic coatings, in particular plastic, the coating material applied in a liquid consistency to the rolling material and dried using the heat supplied by the rolling material and, if necessary, is burned in »

Bandstahl wird insbesondere zum Zwecke des Korrosionsschutzes mit nichtmetallischen Überzügen versehen, nämlich lackiert bzw» mit Kunststoff beschichtet« Dabei kann das Überzugsmaterial auch in flüssiger Konsistenz aufgetragen und der auf dem Walzmaterial befindliche Überzug getrocknet und gegebenenfalls eingebrannt werden. Das geschieht im allgemeinen in der Weise, ( daß das, sofern erforderlieh, zunächst entzunderte Walzmaterial mit dem Überzugsmaterial beschichtet und sodann einer Wärmebehandlung unterworfen wird» 2s ist auch schon vorgeschlager worden, das|| Walzmaterial zunächst zu erhitzen und sodann Xfjh beschichten, wobei die dem Walzmaterial innewohnende Wärme zur Trocknung des Überzugsmaterials ausgenutzt wird. ,Strip steel is provided with non-metallic coatings, especially for the purpose of corrosion protection, namely painted or "coated with plastic". The coating material can also be applied in a liquid consistency and the coating on the rolling material can be dried and, if necessary, baked. This is generally done in such a way (that, if erforderlieh initially descaled rolled material with the coating material coated, and then a heat treatment is subjected to '2s has also been pre-hit, first to heat the || rolling material and coating then Xfjh, wherein the the heat inherent in the rolling material is used to dry the coating material.,

Kaltgewalztes Material muß nach dem Auswalzen in der Regel einer Bntspannungsglühung unterworfen werden. Bei solchem Material erfolgt das Aufbringen des nichtmetallischen Überzugs bislangCold rolled material usually has to be rolled out after it has been rolled out be subjected to stress relief annealing. In the case of such a material, the application of the non-metallic coating has hitherto been carried out

Der Erfindung gemäß' wird nunmehr ein Verfahren sur Beschichtung von Walzmaterial, insbesondere von Stahlband mit nichtmetallischen Überzügen, insbesondere Kunststoff, vorgeschlagen, wobei das Überzugsmaterial in flüssiger Konsistenz auf das Walzsaaterial aufgetragen und unter Ausnutzung von dem Walsaaterial zugeführte.?

When choosing the glow unit, it must be taken into account which temperature the feed material can withstand.

Das Verfahren gemäß der 2r,findung spart in vorteilhaft ei' V/eise eine gesonderte Wärmebehändlung für das Trocknen bsw. für das Einbrennen des "ubercugsmaterials ein.

geraäße Verfahren erweist sich dem vorbekannten Verfahren gegenüber also in wünschenswerter Yfeise seit- und kostensparend.straight process turns out to be compared to the previously known process So in a desirable Yfeise side and cost saving.

Das Verfahren ist gleichermaßen für Kaltband wie auch für kaltausgewalzten bzw» -gezogenon Draht anwendbar= Der Nachbehandlung kann bei Band eine Zerteilung auf geringere Breiten vorausgehen;, so daß die Mantelfläche des Endproduktes in jedem lalle von einem geschlossenen Überzug umgeben ist« fThe process is the same for cold rolled strip as well as for Cold-rolled or -drawn wire can be used = after-treatment In the case of tape, this can be preceded by a division into smaller widths, so that the outer surface of the end product in every one is surrounded by a closed covering «f

Das Verfahren ist anhand der in der Zeichnung schematisch dargestellten, zur Durchführung des yerf-ahrens geeigneten Anlage erläutert. Das su einem Coil 1 aufgewickelte Band 11 läuft von einem Haspel 2 ab und wird durch eine Rolle 3 umgelenkt durch die Lack- bzw. Kunststoffauftragsvorrichtung hindurch und dem Durchlaufofen 5 zugeführt. Tn dem Durchlaufofen erfolgt die ohnehin erforderliche Glühbehandlung des Bandes 11, die gleichzeitig die Trocknung bzw. das Einbrennen des zuvor auf das Band 11 aufgetragenen nichtmetallischen Überzugs bewirkt. Das spannungsfrei geglühte und mit dem getrockneten und gegebenenfalls eingebrannten nichtmetallischen Überzug versehene Band 11 wird durch die Rollen 6 und 7 umgelenkt e'inem · Haspel 8 zugeführt und zu dem Coil 1' aufgewickelt.The process is schematic based on the one in the drawing shown, suitable for carrying out the driving explained. The tape 11 wound up on a coil 1 runs off a reel 2 and is deflected by a roller 3 through the paint or plastic application device and the Continuous furnace 5 fed. This takes place in the continuous furnace anyway required annealing treatment of the strip 11, the at the same time causes the drying or burning-in of the non-metallic coating previously applied to the strip 11. The stress-free annealed and provided with the dried and optionally baked non-metallic coating Belt 11 is deflected by rollers 6 and 7 e'inem · Reel 8 is fed and wound up to form the coil 1 '.
