| Revamping of Billet Mill for a Continuous and Synchronized Operation Nobutsune Hirai, Masanori Yoshihara, Teruyuki Nakanisi |

Synopsis : A modernization program for billet, bloom and shape products was established at Mizushima Works generally aiming at streamlining the complicated crisscrossing of in processes from the two continuous bloom casters to the succeeding rolling mills. A new billet mill, which was a significant part of this modernization, was brought into operation in February, 1984. The billet rolling facility has the "roll-chance-free" function in order to realize continuous and synchronized production between the continuous casters and the new billet mill. This new factory has realized drastically laborsaving and rationalization of handling and transporting by several new techniques, such as the highly computer controlled vehicle (HCCV) system, quick roll changing system, and automatic shipment system for round billets. Operation and information processing are fully computerized over the entire process from steel making to billet shipping. Operation of the new billet factory has brought much benefit in energy and laborsaving, high yield, higher productivity, and so on. |
