Description
изводства, т.е. уменьшение количества брака.production, i.e. reducing the number of defects.
Способ осуществл етс следукщим образом .The method is carried out in the following manner.
Дл измерени истинной температуры полимерного сло производ т загрузку на конвейер нагревательной печи одног или нескольких пакетов-зталонов со встроенными в их промежуточный слой датчиками сопротивлени . На выходе пакетов-эталонов из печи датчики подключают к вторичному прибору, показывакицему достоверное значение температуры полимерного сло . Если температура полимерного сло превышает величину , требуемую по технологии, то Производ т снижение напр жени на электронагревател х и равнозначное и одновременное повьш1ение напр жени на электродвигателе привода. Таким образом , осуществл ют одновременное снижение температуры газовой среды и увеличение скорости конвейера, т.е. уменьшение времени нахождени пакетов триплекса в нагревательной печи. Корректировка подобным методом осуществл етс за значительно меньпшй промежуток времени, чем в известном. В случае, если вторичный прибор показывает температуру меньшую, чем требуема по технологии, то производ тTo measure the true temperature of the polymer layer, a heating furnace is loaded with one or several ztalon packages with resistance sensors embedded in their intermediate layer. At the output of the standard packages from the furnace, the sensors are connected to the secondary device, indicating a reliable value of the temperature of the polymer layer. If the temperature of the polymer layer exceeds the value required by the technology, then the voltage on the electric heaters is reduced and the voltage on the electric motor of the drive is increased and equal at the same time. Thus, a simultaneous decrease in the temperature of the gaseous medium and an increase in the speed of the conveyor, i.e. reducing the time spent by the packs of triplex in the heating furnace. Correction by a similar method is carried out for a much smaller period of time than the known one. In case the secondary device shows a temperature lower than that required by the technology, it is produced
увеличение напр жени на электронагревател х и, соответственно, уменьшение напр жени на такую же величину на электроприводе. Увеличение количества тепла, отдаваемого электронагревател ми , сопровождаетс соответствующим уменьшением скорости конвейера , т.е. увеличением времени нахождени пакетов триплекса в нагревательной печи.an increase in the voltage on the electric heaters and, accordingly, a decrease in the voltage by the same amount on the electric drive. An increase in the amount of heat given off by electric heaters is accompanied by a corresponding decrease in the speed of the conveyor, i.e. an increase in the time spent by the packs of triplex in the heating furnace.
