KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei der Walzenmüllerei kommen zwei Arten von Walzen, nämlich aus Hartgufs und Porcellan hergestellte, zur Verwendung. Während nun erstere eine sehr lange Dauer besitzen, ist die Dauer der Porcellanwalzen von vielen Zufälligkeiten-abhängig und deshalb unsicher. Der Bruch einer Porcellanwalze erfolgt oft ohne jede sichtbare Ursache. Aufserdem ist die Beschaffung von Porcellanwalzen an vielen Plätzen äufserst schwierig und mit grofsen Opfern an Zeit und Geld verknüpft.In roller milling there are two types of rollers, namely hard cast iron and porcelain manufactured for use. While the former have a very long duration, the is Duration of the porcelain rollers depends on many coincidences and is therefore uncertain. Of the A porcelain roll often breaks without any visible cause. Also is the Obtaining porcelain rollers in many places extremely difficult and with large amounts Sacrifice linked to time and money.
Nachstehend beschriebene Erfindung bezweckt nun die Herstellung von Walzen, die die Stabilität des Hartgusses mit den Vorzügen des Porcellans oder einer zweckentsprechenden Ersatzmasse desselben bieten.The invention described below now aims to manufacture rolls that the stability of chilled cast iron with the advantages of porcelain or an appropriate one Offer substitute mass of the same.
Zu diesem Zwecke wird der Mantel der Hartgufswalzen mit Aussparungen beliebigen Querschnittes versehen, von denen abc (Fig. 1) einige Beispiele geben. Diese Aussparungen können nuthenförmig, parallel zur Längsachse über den Mantel geführt werden (Fig. 2 und 6), oder rechtwinklig zu demselben (Fig. 5 und 6), oder in linken oder rechten Schraubenwindungen von beliebiger Steigung (Fig. 4), können aber auch jede beliebige andere Form haben. Die abgewickelten Walzenmäntel (Fig. 7, 8, 9 und 10) geben hiervon einige Beispiele. In den Fig. 3 bis 10 sind ddd die Aussparungen, e e e die stehengebliebenen Rippen des Walzenmantels. For this purpose, the shell of the hard cast iron rolls is provided with recesses of any cross-section, of which abc (Fig. 1) give some examples. These recesses can be grooved, parallel to the longitudinal axis over the jacket (Fig. 2 and 6), or at right angles to the same (Fig. 5 and 6), or in left or right helical turns of any pitch (Fig. 4), but can also have any other shape. The unwound roll shells (FIGS. 7, 8, 9 and 10) give some examples of this. 3 to 10 are ddd the recesses, eee the remaining ribs of the roll shell.
In den Aussparungen a be ddd werden nun entweder dem Querschnitt entsprechend geformte Stücke aus Porcellan, künstlicher oder natürlicher Steinmasse oder einem beliebigen anderen zweckentsprechenden Material eingesetzt und auf beliebige Weise befestigt, oder das Material wird in loser oder breiiger Form in die Aussparungen gebracht und in diese eingestampft oder eingeprefst. Schliefslich werden alle Unebenheiten der Mantelfläche durch Drehen oder Schleifen entfernt und die Walze ist zum Gebrauch fertig.In the recesses a be ddd , pieces of porcelain, artificial or natural stone mass or any other suitable material are now inserted and fastened in any way, or the material is brought into the recesses in loose or pulpy form and in them pulped or pressed in. Finally, all unevenness of the outer surface is removed by turning or grinding and the roller is ready for use.
Ist das in den Aussparungen ab c d d. .. befindliche Material durch den Gebrauch schadhaft geworden, so ist dasselbe ohne besondere Schwierigkeit zu entfernen und an Ort und Stelle zu ersetzen.Is that in the recesses from cd d. .. material located there has become damaged through use, it can be removed without any particular difficulty and replaced on the spot.
