Open-Hearth Steelmaking and Ingots Rolled into Slabs

United States - Circa 1946: Archival film documents open-hearth steelmaking: furnace hearth above with checker-brick regenerators below; preheated air and fuel reverse every 15 minutes; the melter checks a peephole and samples go to the lab; tapping pours molten steel to ladles as lighter slag overflows; teeming into molds forms ingots; soaking pits equalize heat; 23,000-lb ingots exit and roll into slabs under heavy mills, like a wringer.
