ABSTRACT:
A given target temperature profile T is produced in a workpiece as it passes through an elongated passageway of a belt furance by the steps of: (1) determining a set of temperature setting TS.sub.X for the belt furnace thermostats which satisfy an equation f(.alpha.,TS.sub.X,CF.sub.Y).apprxeq.T where .alpha. is a set of thermal parameters for the workpiece, CF.sub.Y is a set of correction factors, and f( ) is a function which approximates the temperature of said workpiece based on TS.sub.X,.alpha., and CF.sub.Y ; (2) measuring an actual temperature profile A(TS.sub.X) of the workpiece in the furnace with the heater thermostats at the settings TS.sub.x ; (3) terminating if the measured actual temperature profile A(TS.sub.X) matches the target temperature profile T within a predetermined tolerance; otherwise, (4) determining a new set of correction factors which satisfies an equation f(.alpha.,TS.sub.X,CF.sub.Y)=A(TS.sub.X); and thereafter repeating the above steps.
