Description

Verfahren zur Schmierung von Pilgerdornen Die Erfindung betrifft ein Verfahren zur Schmierung von Pilgerdornen.Method for lubricating pilgrim thorns The invention relates to a Method of lubricating pilgrim thorns.

Es ist bereits allgemein bekannt, als Schutz-bzw. Schmiermittel, die das Anhaften der Werkzeuge an Werkstücken verhindern sollen, Fett, Ü1, Graphit, Isohlepulver und Sägespäne zu verwenden. Es ist auch vorgeschlagen worden. um das Ankleben des Werkstoffes an der Matrize bzw. an dem Dorn bei Strang pressen zu vermeiden, in die Strangpresse Schmiermittelcarbonate unter hohem Druck einzupressen.It is already well known as a protective or. Lubricant that to prevent the tools from sticking to workpieces, grease, Ü1, graphite, Use insulating powder and sawdust. It has also been suggested. about that To avoid sticking of the material to the die or mandrel when extruding, to inject lubricant carbonates into the extruder under high pressure.

Pilgerdorne wurden bisher vor jeder Auswalzung eines Hohlblockes mit einerMischung von Graphit und UI behandelt, um ein Festschweißen einzelner Materialteilchen auf dem Dorn zu verhüten und in der Hauptsache das Herausziehen des Dornes aus dem fertiggepilgerten Rohr zu erleichtern.Pilgrim thorns have so far been used before each roll-out of a hollow block a mixture of graphite and UI treated to weld together individual particles of material to prevent on the thorn and in the main the pulling out of the thorn from the ready-pilgrim tube to facilitate.

Es hat sich nun gezeigt, daß das Graphit als Rückstand im fertiggewalzten Rohr verbleibt und bei dein Blankbeizen von Rohren hinderlich ist. Auch die anderen ohenerw;ilinten bekannten. Mittel können zur Schmierung von Pilgerdornen nicht Verwendung finden, weil sie sämtlich das Blankbeizen erschwerende Rückstände hinterlassen.It has now been shown that the graphite as a residue in the finish-rolled Pipe remains and is a hindrance to your bright pickling of pipes. The others too Well known. Means cannot be used to lubricate pilgrim thorns because they all leave residues that make bright pickling difficult.

Erfindungsgemäß wird nun statt Graphit ein leicht schmelzbares Salz, wie z. B. Soda. verwendet, das infolge der beim Walzverfahren nötigen Temperatur flüssig wird, wodurch die geforderten Aufgaben, die sonst das Graphit löst, vollkommen erfüllt werden, ohne daß jedoch irgendwelche für das Beizen hinderliche Rückstände verbleiben.According to the invention, an easily meltable salt is now used instead of graphite, such as B. Soda. used, as a result of the temperature required in the rolling process becomes liquid, which completely fulfills the required tasks that graphite would otherwise solve be met, but without leaving any residues that could hinder the pickling process remain.

Das Aufbringen dieser Salze kann mit (51. Wasser oder anderen Bindemitteln erfolgen.These salts can be applied with (51.water or other binders.
