Abstract

A steel ribbon is laminated on both sides with a layer of Al. AFter lamination, the ribbon is annealed for 36-40 hrs. at 500-540 degrees C. At this temp. the layers are not affected in any negative manner. After annealing, the laminated ribbon is rolled to its final thickness. The finished ribbon is then split along the longitudinal direction in order to obtain several ribbons of various width.

Description

Verfahren zur Hersytellung von beidseitig Aluminium-plattiertenProcess for the production of aluminum clad on both sides

Stahlbändern Zusatz zu Patentanmeldung P 26 30 84+.1 ~~~=====~=~~== =======~~==========================~~========= Gegenstand der Hauptanmeldung ist ein Verfahren zur rationellen Herstellung beidiseitig Aluminium-plattierter Stahlbänder, die zur Herstellung von rundgewalzten Rohren vorgesehen sind. Bei diesem Verfahren werden die Aluminiumbänder auf an sich bekannte Kaltbänder aus weichen unlegierten Stählen mit den Gütebe- dingungen nach DIN 1624 aufgewalzt. Bekannt sind unplattierte Stahlbänder nach den Gütevorschriften von DIN 17 175 (nahtlose Rohre aus warmfesten Stählen). Für diese warmfesten Stahlbänder ist für das Glühen nach dem Schweißen bzw. Walzen eine Glühtemperatur von 6500 Celsius bis 7000 Celsius vorgeschrieben. Die Temperaturen kommen für das Glühen von Aluminium-plattierten Stahlbänder nicht infrage, da sie zu nahe an der Schmelztemperatur des Aluminiums liegen.Steel bands Addition to patent application P 26 30 84 + .1 ~~~ ===== ~ = ~~ == ======= ~~ ================ ========== ~~ ========= Subject of the main application is a process for the efficient production of aluminum-clad steel strips on both sides, which are intended for the production of rolled tubes. In this process, the aluminum strips are applied to known cold strips made of soft unalloyed steels with the quality class conditions according to DIN 1624. Unplated steel strips according to the quality specifications of DIN 17 175 (seamless tubes made of heat-resistant steels) are known. For these heat-resistant steel strips, an annealing temperature of 6500 Celsius to 7000 Celsius is prescribed for the annealing after welding or rolling. The temperatures are out of the question for annealing aluminum-clad steel strips because they are too close to the melting temperature of the aluminum.

Man hat sich die Aufgabe gestellt, das Verfahren nach der Haupt anmeldung im Hinblick auf eine rationelle Her tellung von warmfesten Aluminium-plattierten Stahlbändern weiter zu entwickeln und in Gestalt der Verfahrensschritte nach dem beiliegenden Patentanspruch eine Lösung dafür gefunden.You have set yourself the task of the procedure after the main registration with a view to the rational production of heat-resistant aluminum-clad To further develop steel belts and in the form of the process steps after attached claim found a solution for this.

Die bei diesem Verfahren angegebenen Glühtemperaturen haben, wie Erprobungen gezeigt haben, keinerlei negativen Einfluß auf die beidseitig gewalzten Aluminiumbänder. Die Werte für die Warmzugfestigkeit der Stahlbänder, die nach dem erfindungsgemäßen Verfahren hergestellt wurden, liegen bei weitem höher als die entsprechenden Werte der Aluminium-plattierten Bänder aus weichen unlegierten Stählen nach DIN 1624, sie erreichen nahezu die bei nicht plattierten warmfesten Stähle nach DIN 17 175 üblichen Werte.The annealing temperatures given in this process have been tested have shown no negative influence on the aluminum strips rolled on both sides. The values for the hot tensile strength of the steel strips obtained according to the invention Processes were produced are far higher than the corresponding values the aluminum-clad strips made of soft unalloyed steels according to DIN 1624, they almost reach those of non-clad heat-resistant steels according to DIN 17 175 usual values.
