Round-to-Square Share-Roller Tube Mill (XZTF)

ZTZG has studied a new forming process, the technology of ‘Round-to-square without replacing molds’ or XZTF share-roller technique. 

Products Details

It utilizes the round-to-square technique while allowing customers to use one set of rollers to produce all square pipe range within the set range, and shared-use break-down section rollers when producing round pipe, saving significant roller cost and increase productivity. Combined with our ZTF technique, it allows full automatic adjustment of roller position with minimum to none need of manual adjustment, reducing labor maintenance cost and risk of hazard.

High Efficiency

Line speed can be up to 120m/min.

Low Wastage

Low unit wastage and low production cost.

High Accuracy

Diameter error is only 0.5/100 of the pipe OD.
