Abstract
A solid-bowl centrifuge screw with a screw hub with a first welding layer applied to a base, and at least a second welding layer applied to the first welding layers. Thus, the screw hub is produced by a shaping build-up welding method.
Claims10
A solid-bowl centrifuge screw (10) comprising a screw hub (20) having a base, a first welding layer on the base and at least a second welding layer on the first welding layer so that at least a portion of the screw hub (20) has a shaping build-up welding structure that extends from the base and that includes an inlet chamber (94) comprising plural welding layers produced by shaping build-up welding.
The A solid-bowl centrifuge screw (10) comprising a screw hub (20) having a base, a first welding layer on the base and at least a second welding layer on the first welding layer so that at least a portion of the screw hub (20) has a shaping build-up welding structure that extends from the base and that includes an inlet pipe (98) comprising plural welding layers produced by shaping build-up welding.
A production method for forming a screw hub (20) of the solid-bowl centrifuge screw (10), the production method comprising:
- forming a base by a turning method;
- applying a first welding layer on the base;
- and
- applying at least a second welding layer on the first welding layer so that at least a portion of the screw hub (20) has a shaping build-up welding structure that extends from the base and that includes an inlet chamber (94) comprising plural welding layers produced by means of shaping build-up welding.
