Ring forgings and the common distinction between what a large flange
A forging is an article in which a metal is applied with pressure to shape the desired shape or a suitable compressive force by plastic deformation. This force is typically achieved by using a hammer or pressure. The forging process creates an elaborate grain structure and improves the physical properties of the metal. In the actual use of components, a correct design allows the particle flow in the direction of the main pressure.
Large flange is the first cut into the appropriate sliver in the board, the length of the sliver according to the specifications of the large flange. And then with the volume ring machine made of a circle, with the electrode welding to the interface firm, weld to be X-spectrum test. And then press the flattened, and then lathe for water processing, chamfering and other processes, and finally with the index plate with a drilling machine for bolt hole drilling of the processing. It is not possible to hit a bolt hole in a place where a large flange is welded to the bolt hole.
Large flange of the production process forging and rolling and stitching three. Product size is too large only with the rolling and splicing process.
Ring forging process characteristics are: its smelting, forging process to a considerable extent, the impact of the forging properties. The ring-shaped forgings produced by GH4169 alloy bar using vacuum induction and vacuum consumable melting remelting double-melting process were analyzed. The low-power microstructures were observed through the anatomical observation of the defect position. The results show that the main reasons for the formation of low-fold defects in the ring-shaped forging are the segregation of Nb, Ti, δ-phase and MC-enrichment, which are defects in the smelting process. Forging processing non - dominant inducement factors.
The advantages of forging have stretchable length, shrinkable cross-section; retractable length, extensible cross-section; changeable length, changeable cross-section. Forging of the types are: free forging / hand forging, hot forging / precision forging, upset forging, rolling and forging and forging.
