Shougang Changzhi Iron and Steel Co., Ltd. (hereinafter referred to as Changzhi Iron and Steel), founded in 1946, was the first iron and steel enterprise (Guxian Iron and Steel Plant) built by the CPC in Taihang Mountains Revolutionary base area that year.

Every time we approach Changgang, we can always feel the striving and uplifting atmosphere of Changgang people, as if we are back in that era, with those ancestors vaguely by our side.

At Changgang, Gaozhida was fortunate to have won the bid to contract for the speed improvement project of the 8 # continuous casting machine. This project is a key link in Changgang's direct rolling strategy, and it officially ceased production and started construction in the first lunar month of 2022. The total construction period, including civil construction, installation, and debugging, is only 55 days. During that period, it happened that Omicron was raging. We overcame various difficulties and worked together with the people of Changgang to successfully put into production on schedule, and achieved the design targets that month, laying a solid foundation for Changgang to achieve the strategy of hot delivery, direct rolling, and energy conservation and consumption reduction.
