Tata Steel UK’s £1.25 billion investment in green steelmaking, is transforming the future of steel production — and it’s about much more than just the Electric Arc Furnace (EAF), as the company's latest podcast reveals.
“It is a massive project and a massive challenge. While it may fly under the radar, it is as big an investment as the blast furnace replacement a number of years ago — it's a real step forward for the mills.” — Andrew McGregor, Mills CAPEX Lead
Most people know the EAF will use scrap steel instead of raw materials, but the investment also covers crucial upgrades to Port Talbot’s Hot Strip Mill and Pickle Line — parts of the process that shape steel slabs into usable coils.
Many key components of the Hot Strip Mill, like the crop shear and coil box, are nearing the end of their operational lives. Replacing them is essential to keep the mill running efficiently for another 10 to 15 years.
“If we haven’t got crop shear and coil box, we haven’t got a hot mill operation. We haven’t got a sustainable business.” — Andrew McGregor
The Hot Strip Mill is a vital bottleneck in the steelmaking chain, with almost every product passing through it.
Alongside this, the old Pickle Line, which prepares steel sheets for further processing, is being replaced with a new line that will increase capacity to 1.8 million tonnes — future-proofing the site and enabling growth.
“This new pickle line is not just replacing old equipment, it’s an enabler for the future to make sure we are sustainable for the next 25 years.” — Andrew McGregor
