Investment Casting Process for Slender Curved Pipe of a Certain Titanium Alloy Oil Line Sealing Cover
In response to the structural characteristics and casting difficulties of a certain titanium alloy oil pipeline sealing cover casting with small diameter and large aspect ratio,the design adopts the inlay casting process,focusing on the casting method and precautions of the inlay casting metal pipe.Measures have been taken from the process design to solve the problems of shape control,positioning,thermal expansion deformation,etc.of the slender elbow,ensuring the overall structure of the product oil pipeline casting and forming.The results show that the titanium alloy slender oil pipeline is formed by the inlay casting process,and the inner cavity of the casting is free of defects such as cracks,slag inclusions,and pores.The appearance and internal quality of the product meet the requirements of use,and the dimensional accuracy reaches CT7 level.
