Abstract

PURPOSE:To control the temperature of the strips in the furnace with good precision, by setting the furnace temperature from the model formula for heat transfer, calculating the value of actual result of the overall heat-transfer coefficient from the transferring speed of the strips and the furnace temperature, comparing this value with the aimed value and determining the modified set furnace temperature. CONSTITUTION:By computing the heat capacity for the measured values T1 and TO of the temperature of the strips at the inlet side and outlet side of the furnace with the computer P, and by computing from the mean furnace temperature Tg computed with the computer R, the mean temperature Tm, the constant and the heat capacity of the strips in the furnace computed with the computer N and the transferring speed V of the strips with the computer Z, the value of actual result Ha of the overall heat-transfer coefficient is determined. Besides, the difference between the aimed value Tf and the measured value TO of the temperature of the strips at the outlet side of the furnace is determined with the computer U. By using these values, the modified set furnace temperature Tc' is determined with the computer Y and the adding machine E'. By using this modified set furnace temperature Tc', the former set furnace temperature is modified by shutting the switch Sb1 at a definite period.
