The second steelmaking plant of Wuhan Iron and Steel Co., Ltd. is the first to introduce a 1.7-meter rolling mill. Production has been suspended for two years. When Baogang merged with Wuhan Iron and Steel Co., Ltd., coupled with the recovery of the steel industry, it was decided to restart and resume production. On this basis, Wuhan Iron and Steel Measurement & Control Co., Ltd. decided to use our TORLEO basic single-acting intelligent valve positioner to transform KOSO's valves and replace the intelligent valve positioner of Japan's Yamatake. All have been successfully installed and debugged.
