| Synopsis: The development of steel plate manufacturing technologies at Kawasaki Steel since 1987 is described. A proximate Α-ray thickness gauge at a distance of 2 m from the finishing mill, a remodeled hydraulic AGC, and head and tail end thickness control systems were developed as the constituents of the advanced methods for plate thickness control. A shape control system composed of work roll bending force control based on data from a shape meter, an improvement on accelerated cooling device control for uniform cooling, and the renewal of hot leveller improved flatness. A milling machine and a new plate length meter on the shearing line achieved highly accurate edge cutting. A 3-head Α-ray thickness gauge, a flatness meter, and a plan view shape meter were installed on the shearing line as automatic inspection devices. |
