Product Description

Diescher Disc for Seamless Pipe Piercing Mill And Hot Rolling Mill

Description
Pipe blank 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.The guide disc has an axial front tension on the blank during the piercing process, which can increase the axial velocity of the hollow billet and reduce the ellipticity, which is beneficial to the piercing process and speed improvement. The guide disc is composed of two parts: the contact arc radius and the thickness .The profile and thickness are important technical parameters of guide disc.The profile is determined by inlet radius and outlet radius and the thickness is determined by the minimum roll distance and the minimum gap between the guide disc and the roll.

Material: Nodular iron

Produce method: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.

Hardness:340-360HV
