RU: Рассмотрен способ прогнозирования и управления качественными характеристиками прокатных валков в технологии их производства путем использования композиции пассивного и активного экспериментов.
EN: There are various methods of isolation, passive and active experimentation. The first of which is based on the formation of prediction models based on ana League investigated the background of technology in her work area, and the second — to study the mathematical model, based on the analysis of the interaction process variables that can quantitatively dominate the upper and lower level workspace. For example, using the method of passive experiment investigated the polymerization process in the factory. Based on the statistics of recent years were obtained regression equation, where the objective function performed viscosity product as well as arguments were: degree of conversion, the number of controlled reagent and reaction time. All this information enables passive experiment is important to monitor and control the quality of the finished product, but it is clearly insufficient for process control at the level where the process variables are outside the workspace.
The closest to the proposed method is active experiment, which used a matrix planning to identify factors that have a dominant effect on the rate of chlorination of titanium slag melt.
The disadvantages of passive experiment is to create the forecast model, which is based only on an analysis of the background using a particular technology, where variables are only of value obtained in the work area or close to them. The disadvantages of the active experiment based on the method of planning, is the choice of variables and their upper and lower levels as close to the work area, excluding the study those values that are outside still not used. These shortcomings restrict the scope of applicability of these methods in solving problems of prediction and control of quality characteristics iron which projected only in the workspace.
The basis of this work is the task of improving the method of prediction and control of quality characteristics rolls in their production technology, which as a result of composition. passive and active experimentation becomes possible to predict their mechanical properties not only within the workspace, but also abroad.
