Hot commissioning of coiler No. 3 at POSCO hot strip mill

by Hans Diederichs

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.
