Abstract
PURPOSE:To enhance the response characteristics of the titled control by a method wherein a signal of necessary heat amount for heating or cooling is calculated and is used as a basis, and a control output signal is auxiliarily used only when the plate temperature on the furnace outlet side is deviated from a set point. CONSTITUTION:The plate temperature To ( deg.C) on the furnace outlet side is controlled at a set point Ts ( deg.C) by the heating and cooling in the continuous furnace. In the case of heating, the necessary heat amount signal A% is calculated by a calculator 11 in accordance with equation I, where Ti is the plate temperature ( deg.C) on the furnace inlet side, W is plate width (cm), t is the plate thickness (cm), s is the feed speed (cm/min) of plate, xsi is the specific gravity (kg/cm<3>) of plate, gamma is the specific heat (kcal/kg deg.C) of plate, eta is the thermal efficiency (%), Q MAX is the maximum value of necessary heat amount (kcal/min). In the case of cooling, the signal A% is calculated in accordance with formula II. On the other hand, a plate temperature indicating controller 12 gives an output signal B% by conparing Ts and To. An adder 13 provides A%+B%, which is used as a master signal c of the necessary heat amount and is distributed to each zone through a heat amount distributor 15 and the like and fed to respective automatic combustion control system.
