Blast furnace 2 has a hearth diameter of 12 m and an inner volume of approximately 3,300 m³. Average production is 6,900 metric t per day. The third rebuild of blast furnace 2 includes a complete shell and cooling system replacement. The cooling system will be a combination of copper and cast-iron staves from hearth to upper stack. Primetals was contracted to supply nine rows of cast-iron staves. The installation of the new staves is scheduled to take place during a planned shutdown period in 2020. Blow-in of the rebuilt furnace is expected for early 2021.
