Statistical verification of the repeatability regimes at model of the bell furnace

Part of the research of steel coils annealing process was physical model of the bell furnace design. The contribution deals with the verification of the suitability of created object, furnace, in terms of the annealing regimes repeatability. Statistical methods are used for verification. A common method for time series comparison is comparing of the time series values in corresponding sections. The task is complicated by the nature of the physical model, in which heating is by electrical spirals. It is needed time series transformation before the time series values comparison. The transformation procedure consists of smoothening of the time series and adjusting of the working start point. In this publication we will discuss optimization of the moving average sequence, which is used to smooth the time series.
