Description
В процессе выработки стекл нных изделий из расплавленной стекломассы температура рабочих поверхностей формы измен етс в стади х формовани в весьма широких пределах.In the process of making glass products from molten glass mass, the temperature of the working surfaces of the mold varies in the molding steps over very wide limits.
Поэтому начало формовани протекает при низких температурах (ниже оптимальных), вызываюш,их р д различных дефектов на поверхности издели . Поддержание температуры формы в пределах не выше „точки прилипани стекла достигаетс интенсивным ее охлаждением и более или менее длительными перерывами между рабочими циклами выработки.Therefore, the beginning of the molding takes place at low temperatures (below optimal), causing them to be a number of different defects on the surface of the product. Maintaining the temperature of the mold within the range of not higher than the point of sticking of the glass is achieved by intensive cooling of the glass and more or less long interruptions between the working cycles of generation.
Такой способ регулировани температуры рабочей поверхности форм дл заливки расплавленной стекломассы обладает суп1ественными недостатками, а именно;This method of controlling the temperature of the working surface of the molds for pouring molten glass melt has supreme drawbacks, namely;
заниженна температура формы ноблагонри тно вли ет на качество поверхности издели ;the underestimated shape temperature noblononno affects the surface quality of the product;
на охлаждение форм непропзводитслтию тер етс 40% рабочего цикла формовани ;non-production of 40% of the molding cycle time is lost for cooling the molds;
резка смена температуры разрушающе действует на рабочую поверхность форм и сокращает срок их .cutting temperature change has a destructive effect on the working surface of the forms and shortens their life.
Предлагаемый способ имеет целью поддерживать во всех стади х формовани , в том числе и перед загрузкой стекла, практически посто нную заданную температ1уру рабочей поверхности форм.The proposed method is aimed at maintaining, at all stages of molding, including before loading the glass, a practically constant predetermined temperature of the working surface of the molds.
По предлагаемому способу, в conpHKocHOBeiuie с наружной поверхностью формы, вводитс охлаждающее вещество, имеющее заданную температуру. Тепло, переход щее от формуемой стекломассы через форму к охлаждающему веществу, образует двухфазную систему, состо щую из жидкой и твердой фаз, причем форма нриобретает температуру , практически равную температуре охлаждающего вещества. Эта температура остаетс неизменной до тех пор, пока охлаждающее вещество предст авл ет собою указанную выще двухфазную систему.According to the proposed method, a cooling substance having a predetermined temperature is introduced into the conpHKocHOBeiuie with the outer surface of the mold. The heat transferring from the molded glass mass through the mold to the coolant forms a two-phase system consisting of liquid and solid phases, the shape acquiring a temperature almost equal to the temperature of the coolant. This temperature remains unchanged as long as the coolant constitutes the above two-phase system.
