連続鋳造作業の自動化

Automatization of Operator Works in the Continuous Casting Process

田 中 秀 幸(Hideyuki Tanaka) 白 石 伸 司 (Shinji Shiraishi) 岩 永 侑 輔(Yusuke Iwanaga) 日和佐 章一(Shoichi Hiwasa) 下戸 研一(Kenichi Orito) 市原 晃 (Akira Ichihara) 要旨 : 連続鋳造設備の操業において,高熱環境で熟練を要する重筋作業は未だに人手に頼ってい るのが現状である。当社の連鋳工場では,最近,次の4つの作業を自動化してきた。(1)取鍋 用配線・配管着脱装置をスイングタワー上に設置して,自動的に取鍋に連結できるようにし た。(2)タンディッシュイマージョンノズル交換装置をタンディッシュカーに取り付け,赤 熱ノズルを遠隔操作で交換できるようにした。(3)異鋼種連々鋳時の連結金物のセットを遠 隔で行えるようにした。(4)熱間スラブの成分分析用サンプルを機械切削でとれるようにし た。これらの設備は,現在順調に稼働しており,省力や安全の向上,操業安定などに成果を 上げている。 Synopsis :

In the operation of the continuous casting process, incidental works in the environment of high temperature and the treatment of heavy materials have to depend on skilled workers even now. In the continuous casting shop of Kawasaki steel, recently the following four techniques for incidental works have been developed to avoid such hard works: (1) Installation of a cable and pile autocoupler for the ladle on the swing tower; (2) Installation of an immersion nozzle changer for the tundish on the tundish car, where the hot nozzle is changed by using remote control; (3) Installation of setting equipment of the coolant in the mould to avoid the mixing of two different components of steel; (4) Installation of an automatic sampling machine for hot slab in the slab treatment yard, where a sample for component analysis can be taken automatically. All units of these above-mentioned equipment are employed in a good condition now, and have achieved successfully a decrease in the number of operators, safety and the high rate of operation.
