Apparatus for cooling steel blooms, slabs, and the like

摘要

Hot steel slabs are cooled in upright, edge-on state between respective pairs of adjacent cooling walls, each of which comprises a row of intercommunicating boiler tubes conducting cooling water and constituting one component of a circulatory heat recovery system. As the slabs cool, heat is transferred therefrom principally by radiation to the cooling walls, in which the cooling water is turned into a mixture of steam and hot water. A slab handling system comprising roller conveyers, slab uprighting and tilting devices, and a tong crane for picking up and lowering slabs is provided.
