22 April 2020 saw the successful winding of the first coil with the new Uni Plus Coiler, supplied by SMS group for POSCO’s hot strip mill No. 4 at Gwangyang in South Korea. POSCO chose a coiler of SMS group’s Uni Plus design for the expansion of its coiling capacity as this coiler type would enable winding of high-strength steels in the future. 30 coils – including API X70 grade hot strip of 25.4 millimeters thickness and 1,900 millimeters width – were produced during the hot tests.
In the current situation of protective measures being taken all over the world to contain the spread of the COVID-19 virus, production of the first coil was an extraordinary challenge, which the teams of POSCO and SMS group – working in close partnership - mastered successfully. POSCO expressed great satisfaction with the results of this project and congratulated all involved on the success.
