| Description |
The work is aimed at improving the energy efficiency of heating systems of high - temperature pitch at grafite electrodes producing plants. At was previously shown that the of pitch depends not only on its producing technology but on the heating conditions as well, moreover this affects the electrodes time living properties. In this regard the main pitch heating quality task is to archive its homogeneity with minimal time. The process of high - temperature pitch heating working system shown that the following technical factors influence on its heating time: the storage tank feeling; the pitch heating temperature at the outlet; the outlay of the circulating pitch. Using multivariate experiment we got the linear dependence of the high - pitch heating process. The number of experiments N is 8. The regression analysis of the factors influencing the high - pitch heating was carried out. The processing of the performed experimental results and its mathematical model adequacy. The type of connection between tank feeling and pitch circulating outlay as well, as heating time was determined. The regression correlation between the parameters of optimization and variables factors in polynomial form of the first order was calculated. The equation validity of the received regression was checked. It was shown that the storage tank feeling affects on the heating time more that the pitch circulating outlay. The using of such parameters may be recommended as the control functions in the process of high-temperature pitch heating for the time of energy – serving mode. Выполнен регрессионный анализ факторов, которые влияют на время нагрева высокотемпературного пека. Определена форма связи между наполняемостью емкости и расходом циркулирующего пека, а также временем нагрева. Рекомендовано использование данных параметров в качестве управляющих функций процесса нагрева высокотемпературного пека при разработке энергосберегающих режимов |
