Description
Используют описанное устройство следующим образом. Из фидера печи расплав поступает на плиты 1 и 2. Растека сь по площади плит, расплав через зазоры 4 проникает на боковые грани клина 3. По боковым гран м клина 3 расплав стекает к его острию, где формируетс пленка расплава, котора затем раздуваетс энергоносителем по известной схеме способом вертикального раздува.Use the described device as follows. From the feeder of the furnace, the melt enters the plates 1 and 2. Spread across the plate area, the melt penetrates through the gaps 4 to the side faces of the wedge 3. On the side faces of the wedge 3, the melt flows to its tip, where the melt film is formed, which is then blown by energy the known scheme by the method of vertical inflation.
Дл поддержани требуемой температуры расплава к устройству через токоподводы 6 и 7 подвод т электрический ток. Подводимый электрический ток к клину с одной стороны вертикального паза 5 вынужден проходить путь, огиба паз 5 снизу. Ввиду того, что в этом месте сечение клина уменьшено, его заостренна часть будет нагреватьс интенсивнее, в результате чего уменьшаетс градиент температуры расплава по высоте клина 3.In order to maintain the required melt temperature, an electrical current is applied to the device through the current leads 6 and 7. The supplied electric current to the wedge on one side of the vertical groove 5 is forced to pass a path, bending around the groove 5 from below. Due to the fact that at this point the cross section of the wedge is reduced, its pointed part will heat up more intensively, as a result of which the melt temperature gradient decreases along the height of the wedge 3.
Уменьшение градиента температуры по длине клина 3 достигаетс за счет его конструктивных особенностей: конструкцию клина можно представить как бесконечное множество пластинок V-образного сечени равной толщины, соединенных между собой параллельно.The reduction of the temperature gradient along the length of the wedge 3 is achieved due to its design features: the design of the wedge can be represented as an infinite set of plates of V-shaped section of equal thickness, connected in parallel to each other.
Таким образом использование устройства дл подачи расплава на раздув данной конструкции позвол ет за счет уменьшени Thus, the use of a device for feeding the melt to blow up this construction allows, by reducing
градиента температуры расплава по высоте и длине клина обеспечить стабильность процесса выработки расплава. При этом существенно уменьшаетс процент неволокнистых включений в готовом продукте и значительно улучшаетс качество получаемых штапельных волокон.temperature gradient of the melt along the height and length of the wedge to ensure the stability of the process of melt production. This significantly reduces the percentage of non-fibrous inclusions in the finished product and significantly improves the quality of the staple fibers produced.
