Alloy Elbow 90° 273.1*9.27 There are 45,90, and 180 of the three most commonly used
Hot bending forming process is the process of using special elbow press, core mold and heating device, to move the billet forward driven by the press, heating, expansion and bending in the movement. The deformation of the hot bending elbow determines the diameter of the pipe diameter is less than the bending diameter, through the core mold to control the billet deformation process, make the inner arc compressed metal flow, compensate to other parts due to expansion, so as to obtain a uniform wall thickness bend.
The hot push bending forming process has beautiful shape, uniform wall thickness and continuous operation, suitable for mass production, thus becomes the main forming method of carbon steel and alloy steel elbow, and also applied in the shape of stainless steel elbow.
The heating methods of the forming process include medium frequency or high frequency induction heating (heating ring can be multiple or single circle), flame heating and reflection furnace heating. What heating method shall be determined according on the requirements of the forming product and energy situation.
