Description

Pilgerwalze aus legiertem Stahl Werkstoff, der diesen Ansprüchen genügt, wurde gefunden in.einer Stahllegierung; die als wesentliche Bestandteile 1,5 bis 2,2 0/0 Chrom, i,o bis 1,65 % Wolfram und i,o bis 1,65 % Nickel enthält. Die übrigen Bestandteile sind etwa o,6 bis o,$ % Kohlenstoff, 0,4 bis 0,7 % Mangan, o,oi5 bis o,2 Silicium; Phosphor und Schwefel unter 0,03 %. Die Erfindung betrifft eine Pilgerwalze aus legiertem Stahl. Die Pilgerwalzen sind sehr hoch beansprucht, da sie starken und sehr häufigen Stößen ausgesetzt sind. Sie müssen ferner im Betriebe durch Berieselung mit kaltem Wasser gekühlt werden, da sie sonst zu heiß werden und sich sehr rasch abnutzen.Pilger roll made of alloyed steel Material that meets these requirements was found in.einer steel alloy; the 0/0 to 2.2 chromium, i, o containing as essential components 1.5, o to 1.65% tungsten and i to 1.65% nickel. The remaining ingredients are about 0.6 to 0.0% carbon, 0.4 to 0.7 % manganese, 0.05 to 0.2% silicon; Phosphorus and sulfur below 0.03%. The invention relates to an alloy steel pilger roller. The pilgrim rollers are very stressed because they are exposed to strong and very frequent shocks. They must also be cooled in the company by sprinkling with cold water, otherwise they will become too hot and wear out very quickly.

Diese Verhältnisse verlangen daher für die Walzen einen Werkstoff, der mit großer Härte höchste Zähigkeit und Verschleißfestigkeit vereint und gegen rasch wechselnde Temperaturen möglichst unempfindlich ist, also nicht zu schnell die gefürchteten Oberflächenrisse bekommt. Der Werkstoff muß sich ferner verhältnismäßig leicht bearbeiten lassen.These conditions therefore require a material for the rollers which combines the highest toughness and wear resistance with great hardness and against rapidly changing temperatures is as insensitive as possible, i.e. not too quickly gets the dreaded surface cracks. The material must also be proportionate easy to edit.
