The Trunnion Ball is used to control the fluid flow state in the fluid delivery pipeline. Because of the simple structure of the valve sphere, convenient installation and maintenance, good sealing performance, no internal leakage, small volume, etc., it is very popular among market users. Different valve ball blank forging processing methods are different, then what are the specific processing of valve ball blank forging?
1. According to the temperature of the Stainless Steel Trunnion Ball blank forging:
(1) Hot forging: heating the billet to a certain temperature and then forging is called hot forging.
(2) Cold forging: Forging of a billet at normal temperature is called cold forging. The forging equipment required for cold forging has a large tonnage. Cold forging can obtain forgings of higher precision and strength as well as smoother surfaces.
(3) Warm forging: The heating temperature of the billet is lower than the temperature at the time of hot forging. It requires less tonnage than cold forging, and can forge high forging and rough surface forgings, which is a new process in the process of development.
