Abstract (en)

A method of controlling a sliding nozzle device 10 and a plate 13 used therefor, even if operational conditions are changed, automatically optimizing sliding conditions of the device 10, increasing a life of the plate 13, and reducing a corrosion rate and a stroke length of the plate 13. When the device 10 is controlled, if an average cumulative sliding rate of the plate 13 is outside a control range, a sliding rate of the plate 13 is changed within a preset range, thereby automatically optimizing the sliding conditions of the device 10 even with an operational condition change. Also, 3% to 20% of average sliding rate can reduce the corrosion rate of the plate 13 and drastically increase the life of the plate 13.
