Customers who are producing both round
pipes and hollow sections highly appreciate
this system, as it reduces the number of
required roll sets and shortens downtime
during size changes.
Furthermore, a compact and rigid box-
style design has been adopted for the SQ
(squeeze) and TH (sizing/straightening)
stands. This design enables the HF induc-
tion coil to be positioned closer to the SQ
roll center, thereby improving weld qual-
ity, while also providing stable and highly
repeatable pipe straightening performance
at the TH stands.
NAKATA also presented lately developed
IIOT-related software, which grouped by
below four sections.
1) Automation Network & RSS
Newly developed automation network
which integrates Server, Engineering Sta-
tion, Defect Tracking System, Aided System
of Cutting Management and other IIOT
units, along with normal production.
One advantage of this architecture is to
guarantee the data flow in the production
control layer and the information collection
layer independent of each other. At same
time, as a data collection and analysis plat-
form, RSS (Remote Service System) is also
integrated, which aims to allow customer
and NAKATA to work together remotely and
efficiently.
2  Defect Tracking & Optimal Cutting
System
By real-time communication with PLC, coil
head and tail, as well as defects, including
coil joint, unwelded open pipe, untrimmed
OD and ID bead and cutting window, etc.
shall be tracked continuously from the en-
try of mill line to FCO (Flying Cutoff).
The purpose of this software is to help the
operators easily understand defects distri-
bution/positions during production, espe-
cially offering the convenience and guid-
ance to manually or automatically cutting
the pipe longer or shorter than “set-length”.
Besides, by interacting with “optimal cut
program”, this system can also offer the
optimized length pipe cut to maximize pro-
duction yield.
