  • Location: No.100, Longchang Rd., Longjing Dist., Taichung City 434, Taiwan
  • Coordinates (WGS 84): 24.226897, 120.493911 (exact)

Background

China Steel Corporation owns both the Dragon Steel and China Steel Structure plants in Taiwan. It is the only integrated steel plant in Taiwan with blast furnace, basic oxygen furnace and electric arc furnace[1]. Its No.1 blast furnace will be taken offline in 2025 for a partial reline. As part of the revamp effort, the plant will replace the entire set of staves and add ten staves featuring Primetals Technologies to reduce coke consumption and carbon emissions[2].
