Estimating the time of reaching steady-state uniform load temperature of a load in a heat treatment process in the absence of a load temperature sensor. In an embodiment, a system utilizes signals and parameters available on a temperature controller to estimate the period of time required for a load to reach a steady-state temperature in a heat treatment process. When the estimate of the temperature of the load reaches the steady-state condition, the system advances the heat treatment process from a load heating phase to another phase.
