Techint Technologies, Genoa, Italy, started up a thin slab roller hearth furnace, installed at Acciai Speciali Terni, part of the Thyssen Krup Stahl Group, located in Terni, Italy. The furnace is in line with a new CSP caster (single line), a new descaling machine and the existing mill. The new plant is designed to produce stainless steel coils with slabs coming from the existing walking beam furnace and the new roller hearth furnace (mix rolling). Techint designed, supplied, erected and commissioned the furnace.
