Abstract

PURPOSE:To make it possible to set quickly the optimum temperature of the atmosphere and line velocity in the furnace according to the characteristic of the annealing furnace, by computing the radiation rate or the convective heat transfer rate of each furnace from the value of actual result and by computing either of the temperature of the furnace atmosphere and the line velocity at the required furnace using that result.
