After introducing an intelligent inkjet coding system to the 2# hot rolling line at the Stainless Cold Rolling Plant, the plant successfully achieved 100% online inkjet coding for wide-width products. This upgrade directly integrated the inkjet coding process, which was originally completed during the 3# cross-cutting stage, into the 2# hot rolling line for simultaneous execution. For users, this change brought tangible benefits: a shortened product delivery cycle and a faster response to production needs. Meanwhile, the application of this system increased the comprehensive yield by nearly one percentage point, highlighting TISCO's intelligent manufacturing capabilities in the field of lean production and further enhancing users' trust in the stability and consistency of the products. In addition, this technological improvement generated direct economic benefits of approximately over 400,000 yuan, reflecting the plant's outstanding performance in cost control and efficiency improvement.
