U.S. Steel Duquesne Works, Basic Oxygen Steelmaking Plant

The mill was the first to employ the "direct process" by which ingots were rolled directly from the soaking pits without being reheated. Under Carnegie Steel a new blast furnace plant was constructed with the industry's first fully mechanized material handling system, an innovation which came to be called the "Duquesne Revolution."

Steel - Slabs and blooms | Britannica

Slabs and blooms C ast ingots, sometimes still hot, arrive at slab and blooming mills on railroad cars and are charged upright by a special crane into under-floor soaking pits. These are gas-fired rectangular chambers, about 5 metres deep, in which four to eight ingots are simultaneously heated to about 1,250° C (2,300° F).
