PURPOSE:To elevate the control accuracy of the vulcanization process by controlling the vulcanization process depending on the equivalent vulcanization time and vulcanization level at a set point inside rubber from a detection value obtained when the temperature at a plurality of points of a rubber surface changing with time during the vulcanization is detected at a specified time interval. CONSTITUTION:At the step 1, the temperature at a plurality of point on the surface of a rubber 10 varying with time is detected at DELTAt interval. At the step 2, the temperature detected at the step 1 is used as restricting condition to compute the temperature at the set point inside a rubber after DELTAt time by the solution of heat diffusion. Then, at the step 3, the arithmetic processing is performed on the equivalent vulcanization time toi and the vulcanization level x1 at the set reference temperature T0 based on Arrhenius' equation from the temperature computed at the step 2. At the step 4, the computed value toi is compared with the set values toc and xc to judge. At the step 5, a control signal is outputted to a vulcanizer based on the results of the judgement at the step 4 and thus, a higher control accuracy is achieved. |
