Angang expands product portfolio by upgrading heavy plate rolling mill

Chinese steel producer Angang has commissioned Primetals to upgrade the automation of its heavy plate mill in Bayuquan. Following the upgrade of the Level 1 and Level 2 automation in the 3.8-metre heavy plate mill, new process models will improve flatness and profile quality and enable plate thicknesses of up to five millimetres.

Angang has awarded the final acceptance certificate (FAC) to Primetals for a comprehensive automation upgrade at its plate mill in Bayuquan, Liaoning province, China. Primetals has supplied and implemented full Level 1 and 2 automation systems as well as a process camera system and a new human-machine interface (HMI).
According to Primetals, the modernization enables Angang to produce new types of steel, such as the high-performance X60MO subsea pipeline special steel, known for its stringent shape and surface quality requirements. Primetals’ newly implemented advanced process models enable rolling with increased flatness and profile quality, as well as the production of thinner plates down to a thickness of five millimeters. Following the successful modernization, Angang is planning a further expansion of its product portfolio with new steel grades, thereby increasing the proportion of high value-added products.
