Abstract

PURPOSE: To make possible the controlling of outputs without disturbing later processes by changing the timings of programs according to conditions during progression of program controlling.
CONSTITUTION: A standby command is fixed like the solid line in the figure by assuming that the current cooling water flow (y) is not changed. X is defined as drawing length of a cast ingot. If at this time the coordinates after (Xn+1, Yn+1) are fixed, the danger of process stray run occurs at the moment when the standby is released; therefore, the inclination of the graph after the command release β must be held fixed or the coordinates of Xn+1, Xn+2Wmust beforehand be moved by the extent having stood by. Since the standby extent is ΔX, the new coordinates are changed to (Xn+ΔX, Yn), (Xn+1+ΔX, Yn+1)W, hence, the cooling water flow (y) is again controlled along the prelimited program, thus the abrupt output fluctuations are averted.
