Description

(54) ПЕЧЬ ДЛЯ ВЫРАБОТКИ КВАРЦЕВОГО ПРОФИЛЯ(54) FURNACE FOR DEVELOPING A QUARTZ PROFILE

Изобретение относитс  к промышленности строительных материалов, в частности, к оборудованию по производству кварцевого стекла. Известна печь дл  производства кварцевого стекла, состо ща  из кор inyca, смонтированного на схзновании и перекрытого сводом, в рабочем объеме корпуса установлены коаксиально перегородки, причем в центральной перегородке размещена емкос с формующей дюзой. Дл  разогрева пе чи и наплава стекломассы на ЪЬи печи в своде установлена горелка, сов мещенна  с питателем шихты iJ, , Работа печи осуществл етс  следующим образом. Первоначально производитс  вывод ка печи на рабрчий режим, дл  чего факелом через отверстие в своде раз жигают горелку. В течение 24-36 ч повышаетс  температурный режим печи до рабочей температуры (1500-170б с в зоне выброса отработанных газов. Затем включаетс , питатель шихты и начинаетс  наплав стекломассы в ван ну. По достижени.и заданного уровн  начинаетс  выработка стекломассы че рез дюзу. Печь имеет существенный недостаток , заключанвдийс  в том, что в процессе выводки печи материал муфел  ZrOg (двуокись циркони ) под воздействием газовой среды, имеющей избыток водорода - Hj,пре6ращаетс  в Zr-O или , которые имеют более низшую температуру плавлени , чем ZrOg, и начинает разрушатьс , попада  вместе со стекломассой в кольцевые зазоры, образуемые коаксиальными перегородками, а после заполнени  зазоров попадают в ванну наплава стекломасса, в конечном счете загр зн   её. Цель изобретени  - обеспечение чистоты расплава. Поставленна  цель достигаетс  тем, что в печи кварцевого профил , включающей горелку с питателем, смонтированными в муфеле, и формующий элемент, муфель перфорирован на уровне наплава стекломассы, причем отверсти  перфорации соединены кольцевым каналом, св занным с источником поступлени  защитного газа . , В процессе выводки и работы печи в кольцевой канал .через питающие патрубки подаётс  кислород с давлеThe invention relates to the building materials industry, in particular, to equipment for the production of quartz glass. A famous quartz glass production furnace consisting of an inyca core mounted on the mechanism and covered with a vault, coaxial partitions are installed in the working volume of the body, with a capacitance with a forming nozzle located in the central partition. To heat the furnace and surfacing of the glass melt, a burner was installed in the roof of the furnace, combined with the charge feeder iJ,. The furnace operates as follows. Initially, the furnace is put into a working mode, for which the burner is burned through a hole in the arch in the arch. Within 24-36 hours, the furnace temperature rises to the operating temperature (1500-170b in the exhaust gas emission zone. Then the charge feeder is turned on and the glass melt begins to melt into the bath. When it reaches the specified level, the glass melt begins to develop through the nozzle. The furnace has a significant disadvantage in that the material of the ZrOg (zirconium dioxide) muffle under the influence of a gaseous medium having an excess of hydrogen — Hj — converts into Zr-O or which have a lower melting point than ZrOg, and beginning It collapses, falling together with glass melt into annular gaps formed by coaxial partitions, and after filling the gaps into the float bath of glass melt, ultimately contaminated with it. The purpose of the invention is to ensure the purity of the melt. including a burner with a feeder mounted in a muffle and a forming element, the muffle is perforated at the level of glass melt, and the perforation holes are connected by an annular channel connected to the source no shielding gas. During the process of brooding and operation of the furnace, oxygen is supplied from the pressure to the annular channel.
