AI Technical Summary
In existing spinning cooling processes, the constant wind speed of the annular blowing device can easily lead to problems such as spinning deformation or insufficient cooling.
The system employs a multi-stage annular air blowing tube structure, with the air speed of each air blowing tube increasing sequentially from top to bottom. Combined with a nitrogen protection component, this ensures that the spinning process does not deform and is fully cooled during the cooling process.
This effectively avoids deformation during the spinning cooling process and ensures sufficient cooling effect during spinning.
