004642fr004642fr Übersetzung der Ansprüche der europäischen Veröffentlichungsschrift Nr. 0 046 423Translation of the claims of European publication No. 0 046 423 . Im Rahmen der Herstellung von Bändern aus kohlenstofffarmen Stahl, insb. für die Fabrikation von Verpackungen, bei der im Wickel vorliegende Bleche, die aus einer für das kontinuierliche Vergießen bestimmten Stahlsorte stammen, durch einen ersten Kaltwalzvorgang genau auf eine Dicke des Bandes gebracht, in einer die aus dem ersten Walzvorgang stammenden strukturellen Anisotropien verschwinden lassenden Weise geglüht und darauf in einem zweiten Walzvorgang mit schwacher Längung derart gewalzt v/erden, daß das Metall des Bandes auf eine gewählte Härte gebracht wird, ein Verfahren zum kaltverformenden Walzen, um unter der Glocke geglühten Bändern eine Festigkeit zu verleihen, die mit der von kontinuierlich geglühten und durch einen trockenen Walzvorgang mit einer Längung von unter 2 % kaltverformten Bändern vergleichbar ist,, dadurch gekennzeichnet , daß man das Verfahren auf zwei aufeinanderfolgenden Walzgerüsten ausfuhrt, derart, daß die sich ergebende Längung auf einen Wert eingesteuert wird, der zwischen A % und 20 % gewählt und zum größten Teil in dem ersten Walzgerüst erhalten wird, daß man das Band am Eintritt in das erste Walzgerüst durch aufspritzen einer Emulsion von Öl in Wasser schmiert, daß man das Band zwischen den Walzgerüsten mit einem Wasser von einer Temperatur höher als die Umgebungstemperatur wäscht,und daß man das Band am Ausgang des zweiten Walzgerüstes durch Aufblasen von Luft trocknet.. As part of the production of ribbons from low carbon Steel, especially for the manufacture of packaging, in the case of the sheet metal present in the coil, which consists of one for the continuous Shedding certain types of steel come from a first cold rolling process exactly to a thickness of the strip in a manner that makes the structural anisotropies from the first rolling process disappear annealed and then rolled in a second rolling process with slight elongation in such a way that the metal of the strip is on a selected hardness is brought, a process for cold forming Rolling to give bell-annealed strips a strength similar to that of continuously annealed and comparable to cold-formed strips through a dry rolling process with an elongation of less than 2% is ,, characterized in that the process executes on two successive roll stands, in such a way that the resulting elongation is controlled to a value which is chosen between A% and 20% and is obtained for the most part in the first roll stand that one lubricates the strip at the entrance to the first roll stand by spraying on an emulsion of oil in water that one washes the strip between the roll stands with water at a temperature higher than the ambient temperature, and that the strip at the exit of the second roll stand is dried by blowing air on it. 2. Verfahren nach Anspruch 1, dadurch gekennze i c h n e t , daß die Rauhigkeit der Zylinder des ersten Walzgerüstes zwischen 3,5 und 1 Mikrometer Ra liegt, während die der Zylinder des zweiten Walzgerüstes zwischen 0,75 und 0,4 Mikrometer Ra liegt.2. The method according to claim 1, characterized in that i c h n e t that the roughness of the cylinders of the first roll stand is between 3.5 and 1 micrometer Ra, while the the cylinder of the second roll stand between 0.75 and 0.4 Micrometer Ra. 3. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß die Längung in dem ersten Walzgerüst 85 % bis 95 % der gesamten Längung präsentiert.3. The method according to claim 1, characterized in that the elongation in the first roll stand 85% to 95% of the total elongation presented. 4. Verfahren nach Anspruch 1, dadurch gekennze ichn e t, daß die Emraulsion aus 1 % - 10 % Öl in Wasser besteht. 4. The method according to claim 1, characterized in e t that the emraulsion consists of 1% -10% oil in water. 5. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß das Waschwasser eine Temperatur von ungefähr 50 ° Celsius aufweist.5. The method according to claim 1, characterized in that that the washing water has a temperature of about 50 ° Celsius. 6. Verfahren nach Anspruch 1, dadurch gekennzeichne t-, daß das Waschwasser ungefähr 0,2 Gewichtsprozent Matriumnitrit enthält.6. The method according to claim 1, characterized t- that the wash water contains approximately 0.2 percent by weight of sodium nitrite.
