Hot pushing formation of large caliber stainless steel elbow

　　Hot pushing large caliber stainless steel elbow forming process is a process of heating, expanding and bending the blank on the die by large caliber stainless steel elbow pusher, core die and heating device. The deformation characteristics of hot pushing High Quality Large Caliber 304 Stainless Steel Elbow are to determine the diameter of tube billet according to the rule that the volume of metal material remains unchanged before and after plastic deformation. The diameter of tube billet used is smaller than the diameter of large caliber stainless steel elbow. The deformation process of billet is controlled by the core die, so that the compressed metal flow in the inner arc can be compensated to other parts which are thinned due to the expansion of diameter, so that the large caliber stainless steel elbow with uniform wall thickness can be obtained.

　　Hot push large caliber stainless steel elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, which is suitable for mass production. It has become the main forming method of large caliber stainless steel elbow, and also applied to the forming of stainless steel elbows of some specifications.

　　The heating modes of forming process include medium frequency or high frequency induction heating (heating ring can be multiple or single loop), flame heating and reflex furnace heating. The heating mode depends on the product requirements and energy conditions.
