Description

Verwendung eines Stahles zum Herstellen von Flanschen für Kabeltrommeln Die Flansche von aus Stahlblech bestehenden Kabeltrommeln müssen ihrer hohen Beanspruchung wegen besonders widerstandsfähhig sein. Die Auswahl der für ihre Herstellung geeigneten Stahlbleche hat darüber hinaus noch zu berücksichtigen, daß die Flansche durch Profilieren, z. B. durch Einp:rägen radial verlaufender Stege, zu verstärken sind. Materialmäßig liegen die Grenzen zwischeneinem üblichen, Handelsblech und hochlegierten Stahlblechen.Use of steel to produce flanges for cable drums The flanges of sheet steel cable drums have to withstand high loads because of being particularly resilient. The choice of those suitable for their manufacture In addition, sheet steel has to take into account that the flanges are formed by profiling, z. B. by inserting radially extending webs, are to be reinforced. Materially are the boundaries between a common, commercial sheet and high-alloy steel sheets.

Durch eingehende Versuche und betriebsmäßige Erprobung wurde nun gefunden, daß man einen hochwertigen Werkstoff zur Herstellung der Flansche für Kabeltrommeln aus einem Stahl nachstehender Zusammensetzung herstellen kann, wenn dieser Stahl aus einer Bramm.e in üblicher Weise auf ein Rohband von etwa 3 mm Stärke ausgewalzt und vom Rohband mit einer Quers@chnittsabnahme von mindestens 20% in einem Stich kalt auf die erforderliche Abmessung verwalzt wird. Danach kann das Stahlblech ohne Vergüten durch Einprägen der jeweils .erforderlichen Versteifungen auf den Flansch verarbeitet werden. Die Ausgangsrohbramme besteht erfindungsgemäß aus einem Stahl der Zusammensetzung: 0,03 bis o,io % . . . . . Kohlenstoff, Spuren . . . . . . . . . Silizium, 0,2o bis 0,5o % . . . . . Mangan, 01015 - 0,050% . . . . Phosphor, 0,02o - 0,030% . . . . . Schwefel, Rest Eisen. Die erfindungsgemäß hergestellten Kabieltrommelflansche verhalten sich wie Flansche aus hochlegiertem Stahlblech, denen gegenüber sie aber den außerordentlichen Vorteil aufweisen, daß sie durch Kaltwalzung m einen Stich- und mit großer Abnahme Federhärte annehmen, ohne zu versprZden. Insbesondere aber ist der Flanschwerkstoff, ohne daß ereiner Vergütungsbehandlung bedarf, von besonders guter Verformbarkeit.Through in-depth testing and He operational p robung has now been found that one can produce a high-quality material for the production of flanges for cable drums of a steel of the following composition when this steel from a Bramm.e in a conventional manner mm on a raw band of about 3 Strength rolled out and rolled from the raw strip with a cross section decrease of at least 20% in one pass cold to the required dimensions. The sheet steel can then be processed without tempering by embossing the required reinforcements on the flange. According to the invention, the starting raw slab consists of a steel with the following composition: 0.03 to o.10%. . . . . Carbon, Traces . . . . . . . . . Silicon, 0.2o to 0.5o%. . . . . Manganese, 01015 - 0.050%. . . . Phosphorus, 0.02o - 0.030%. . . . . Sulfur, Remainder iron. The cable drum flanges produced according to the invention behave like flanges made of high-alloy sheet steel, but compared to which they have the extraordinary advantage that they take on a puncture and with a great decrease in spring hardness without being damaged by cold rolling. In particular, however, the flange material is particularly deformable without the need for tempering treatment.
