[0002] Hot extrusion is one of the production processes of hot-processed seamless stainless steel pipes abroad. Compared with the rolling production method, the characteristic of the extrusion method is that the metal is subjected to three-dimensional compressive stress during the deformation process. Under this optimal state, high-end stainless steel pipes with large deformation resistance and poor thermoplasticity can obtain better internal and external surface quality and metallographic structure, which is suitable for the production of small batches and multi-specification stainless steel pipes.

However, the device is not convenient to adjust. The structure of the device for extruding stainless steel tubes is a fixed position, so that the device can only process one type of stainless steel tube.
