Synopsis : In the operation of the continuous casting process, incidental operator's work in the environment of high temperature and in 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 operator's work have been developed to avoid such hard work: (1) Installation of a cable and pipe auto-coupler for the ladel 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. |
