A new journey begins in the new spring, with hot test achieving outstanding results!

On February 5, 2026, the full‑line hot test of Jingye Steel 1450mm hot strip rolling widening renovation project was successfully completed.This key project undertaken by EIT has set a new industry record as the world’s first wide‑strip hot rolling system fully based on Siemens S7‑1500 PLC.

The renovation covers all core links of the hot rolling line, completing technical replacement and optimization upgrading of the level‑2 model system, automatic charging and tapping of reheating furnaces, roughing, flying shear, finishing, laminar cooling, coiling and transportation, as well as hydraulic and lubrication control systems.From hardware equipment to software programs, a more efficient and precise control architecture has been built in an all‑round way, achieving a qualitative leap in the automation level of the entire rolling line.

Tough tackling demonstrates engineering excellence.The renovation project featured a tight schedule, heavy tasks, and high technical complexity.During project implementation, the IET team worked efficiently with Jingye Steel and construction units, forming a strong tackling force with seamless coordination across disciplines to ensure accurate transmission of every signal and save valuable time for on‑site commissioning.TheIET automation team worked continuously on site for 35 hours, repeatedly verifying program logic and finely calibrating control parameters, controlling every technical detail with extreme rigor.Ultimately, the shortest commissioning cycle in history was achieved, delivering an outstanding answer with strong engineering strength.

The successful implementation of the Jingye Steel 1450mm hot strip rolling widening renovation project not only marks the mature application of IET’s hot rolling control system based on Siemens S7‑1500 PLC in the wide‑strip hot rolling field, but also fills an industry gap.It provides mature, reliable, and implementable technical support for the upgrading of wide‑strip hot rolling TDC control systems, driving hot rolling control technology to a more efficient and precise new stage.
