摘要： Ein Schneidmesser (1) für eine Schneidvorrichtung in einer Strangeinheit zum Schneiden eines Stranges in stabförmige Produkte, bei dem Material des Messers eine Härte von 1.400 bis 2.200 HV30 sowie eine Biegebruchfestigkeit von 3.600 bis 4.400 MPa aufweist und die Korngröße des Materials von 0,2 bis 1,3 µm beträgt, erfordert kein Schleifen der Messer während des Schneidprozesses und gewährleistet trotzdem eine hinreichend lange Standzeit der Strangeinheit.
Ein Messerhalter (2) für ein solches Schneidmesser weist eine planare Klemmbacke (22) und eine planare Gegenlage (21) auf, wobei die Klemmbacke (22) um ein Klemmbackengelenk (222) justierbar ist, wobei die Klemmbacke (22) mit einem Hebel mit Masse (23) derart in Wirkverbindung steht, dass eine durch den Hebel mit Masse (23) erzeugte Kraft die Klemmbacke (22) gegen die Gegenlage (21) drückt, wodurch das Schneidmesser (1) zwischen Klemmbacke (22) und Gegenlage (21) flächig einklemmt wird.

摘要： Cutting elements having accelerated leaching rates and methods of making the same are disclosed herein. In one embodiment, a method of forming a cutting element includes assembling a reaction cell having diamond particles, a non-catalyst material, a catalyst material, and a substrate within a refractory metal container, where the non-catalyst material is generally immiscible in the catalyst material at a sintering temperature and pressure. The method also includes subjecting the reaction cell and its contents to a high pressure high temperature sintering process to form a polycrystalline diamond body that is attached to the substrate. The method further includes contacting at least a portion of the polycrystalline diamond body with a leaching agent to remove catalyst material and non-catalyst material from the diamond body, where a leaching rate of the catalyst material and the non-catalyst material exceeds a conventional leaching rate profile by at least about 30%.
