Brief introduction
In hot rolling pipe mill, pipe billet piercing procession is the first procedure of seamless steel tube processing.The piercing mill with guide disc is widely used.
Guide disc is a guide device of the piercing mill frame, which is used to form the closed pass of steel pipe.

Produce process:
Raw Material melting---sand casting ---machining----inspection---packing
Advantages:
1. High productivity.The active guide disc produces axial tension on the rolled workpiece,
thus speeding up the axial velocity of the hollow billet.The fastest speed is 3~4 pieces /min.
2. The axial force of the guide disc improves the bite performance of the tube blank, reduces the possibility of internal folding in the tube end, and improves the precision of the
wall thickness.
3. The high wear resistance of the guide disc reduces the time of tool replacement and improves the tool lifetime.
