Abstract
In a sleeve for a gas nozzle, a sleeve main body and a sleeve end face is formed at least in part by a wear protection element which is fastened to the sleeve main body and which is composed of a more wear-resistant material than the sleeve main body adjoining the sleeve end face, an inner and/or an outer beveled portion of the sleeve end face are formed at least in part by the wear protection element.
Claims22
A sleeve for a gas nozzle, comprising:
- a sleeve main body;
- and
- a sleeve end face,
- wherein the sleeve end face is formed at least in part by a wear protection element composed of a more wear-resistant material than that of the sleeve main body,
- wherein one or both of an inner or an outer beveled portion of the sleeve end face is formed at least in part by the wear protection element, and
- wherein a surface portion of the sleeve on which a gas pressure of a gas acts in a forward direction when the sleeve is arranged inside a gas nozzle is 1.2 to 1.4 as large as the surface portion of the sleeve on which the gas pressure acts in a backward direction.
