Leader of CEM Project Team, Technical Research Lab, POSCO, South Korea
Mr. Young Ju Ko has master’s degree in chemical& material Engineering at Chonnam National University in 2005. In the same year he joined POSCO, Gwangyang Steel Work and he worked as a Process Engineer for rolling mill and product quality in Mini Mill Department. Since 2008, he joined the CEM project, which was revamped from ISP, as a rolling process engineer. Since 2010, he worked for process development of endless rolling and started to develop CEM product in 2015. Since 2017, he has been working as a Leader of CEM project team.
Topic: The Innovative Manufacturing Process of Steel Strips, CEM® Compact Endless Casting and Rolling Mill
Abstract: The compact endless casting & rolling mill (CEM), the energy-saving steel making process which directly links a single continuous caster and a single hot rolling mill. CEM mainly composes of thin slab high speed casting technology and endless rolling technology, which are possible to produce thin gauge hot rolled coils more stable than the batch rolling. Uniform product quality can be obtained successfully which sustains unchanging rolling conditions such as the material temperature and the threading speed. Consequently, it is effortless and efficient to control the strip cooling in the run-out table zone to produce automative steel like the advanced high-strength steel. Moreover, CEM product with uniform material quality, great surface quality, accurate thickness and width quality has been brought the excellent results in application of automative manufacturing.
