Title:
CONSTRUCTING AND FORMING METHOD FOR PREPARING HOMOGENIZED FORGE PIECES
Document Type and Number:
WIPO Patent Application WO/2016/150024
Kind Code:
A1
Abstract:
A constructing and forming method for preparing homogenized forge pieces, which relates to the field of forge piece forging. The method comprises: firstly, billet prefabricating: baiting a plurality of blocks of continuous casting sheet billets into assigned sizes, smoothly machining surfaces to be welded through a milling machine, cleaning by adopting vacuum plasma, and performing electron beam sealing and welding on the peripheries of the surfaces to be welded in a vacuum chamber after the billets are overlapped; then, billet forge welding and homogenizing: heating welded billets to an assigned temperature, enabling the billets to get out of a furnace, forging on a hydraulic machine, enabling an interface to be fully welded and scattered by adopting a method for in-forging pressure preservation, in-forging temperature preservation and three-dimensional forging, and guaranteeing that components, tissues and inclusions in a position of an original interface to reach a level being consistent with that of a basal body; and finally, forming: forging the billets into final specifications and sizes. The method breaks through a traditional method for manufacturing forge pieces by adopting a static ingot, continuous billets which are relatively cheap are utilized for overlapping and forging, not only can the manufacturing cost be reduced by more than 20%, but also the problems of macroscopic segregation and central shrinkage cavity and porosity of a big forge piece are completely solved.
