Synopsis : At Chiba Works, a new pickling line was installed as an extension to the No.1 hot strip mill and started operation in November 1984. It has a nominal capacity of 112 000 t/month with a rated capacity of 175 t/h. Features which distinguish this line from conventional pickling facilities include a mechanical descaling system, a new pickling tank, a carrousel tension reel and other automatic facilities. This line adopted a mechanical descaling system, in which scale breaking and removal are done by tension leveler and brush to save acid consumption ratio and improve strip flatness. Administration of the entry coil storage yard and the scheduling of pickling commands are automatically controlled and also combined with the pickling line operations. The computer network of a hierarchy system is adopted from the entry of the coil storage yard to the pickling line, which means fully automatic operations, high quality products and high labor productivity. |
