I&ST was in Nashville for AISTech 2025, see the show highlights in our review.  Ingot casting may not be the highest volume production route in modern steelmaking, but this important method of casting continues to see technological advances, we look at the refractory side of your process. Also in focus, the latest developments in digitalisation, lubricants, power, sustainability and hydrometallurgy.

What is the effect of hydrogen DRI on your EAF steelmaking process? Does submerged arc welding have a benefit over open arc when repairing your rolls? Just two of the questions I&ST looks at this month.

Refractories, digitalisation, our AISTech 2025 show preview and optimisation are just part of the focus for April. As usual, we also bring you the latest news and views from across the global steel industry.
