Steel - Slabs, Blooms, Manufacturing: Cast ingots, sometimes still hot, arrive at slabbing 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). An ingot used for …
