When finished undergoing secondary steel making processes, molten steel is cast into "semifinished" billet, bloom, or slabs preparing the steel for its final physical shape. Forming, Fabricating, and Finishing: Afterwards, steel processing service centers take steel billets, blooms, and slabs and create deliverable steel products.
This innovative continuous process melts, casts and rolls steel from a single uninterrupted strand, producing higher strengths and lower energy costs compared to traditional mini mill processes. In addition to our U.S. micro and mini mill facilities, we operate the second largest long-products EAF mini mill in Poland.

Steel making is a sophisticated process that turns iron ore into steel, involving methods like the Blast Furnace and Electric Arc Furnace to produce various grades of steel. The industry emphasizes sustainability by using additives and recycled materials while ensuring quality through rigorous testing for diverse applications.
Homepage /; About Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route.
Before most cold rolling processes, previously hot rolled steel goes through a pickling line to remove the scale from the surface and make it easier to work. To restore the best corrosion resistant performance, the damaged metal layer must be removed, exposing a fully alloyed stainless steel surface.
Often, when a mill is upgraded, the entry end of the line is overlooked. While the mill capacity may be 600 or 700 feet per minute, this can be limited by the capacity of the accumulator or the speed of the end welding equipment. Overview of Welded Tube Making Line. A mild steel welded tube line typically consists of the …
