Description
Изобретение относитс к способу изготовлени стеклокристаллических изделий, которые предварительно формуют из расплава стекла любыми известными в практике стеклодели способами с последующей термической обработкой .The invention relates to a method for the manufacture of glass-ceramic products that are pre-molded from molten glass by any methods known in practice glass-making with subsequent heat treatment.
Известные способы .изготовлени стеклокристаллических изделий иредусматр вают формование изделий из расплава и последующую их термообработку. Однако при применении этих способов не четко регламентируетс термическа обработка изделий на стадии охлаждени , хот именно этот этап при изготовлении стеклокристаллических изделий вл етс весьма важным процессом, определ ющим качество изделий.Known methods for the manufacture of glass-ceramic products and to reduce the formation of products from the melt and their subsequent heat treatment. However, when using these methods, thermal processing of products at the cooling stage is not clearly regulated, although this stage in the manufacture of glass-ceramic products is a very important process that determines the quality of the products.
Интенсивное охлаждение изделий определ ет повышение качества объемной кристаллизации их, а также повышение экономичеокого эффекта.Intensive cooling of the products determines an improvement in the quality of their bulk crystallization, as well as an increase in the economic effect.
По предлагаемому способу дл обеспечени According to the proposed method for providing
объемной кристаллизации издели обрабатываютс по следуюшему режиму:bulk crystallization of the product is processed in the following mode:
выдержка при температуре 670-750°С от 10 до 70 мин, подъем температуры от 670- 750°С до 930-970°С со скоростью 75-320°С в 1 час, выдержка при температуре 930- 970°С от 10 до 70 лшн и затем охлаждение со скоростью 200-450°С в 1 час.holding at a temperature of 670-750 ° C from 10 to 70 minutes, a rise in temperature from 670-750 ° C to 930-970 ° C at a speed of 75-320 ° C for 1 hour, holding at a temperature of 930-970 ° C from 10 to 70 lshn and then cooling at a speed of 200-450 ° C in 1 hour.
Предмет изобретени Subject invention
Способ изготовлени стеклокристаллических изделий путем формовани их из расплава стекла и последующей термообработки, отличающийс тем, что, с целью обеспечени объемной кристаллизации, издели выдерживают при 670-750°С в течение 10-70 мин, затем повышают температуру со скоростью 75- 320°С в 1 час до 930-970°С и выдерживают при этой температуре в течение 10-70 мин, после чего охлаждают со скоростью 200-450°С в 1 час.A method of manufacturing glass-ceramic products by molding them from a melt of glass and subsequent heat treatment, characterized in that, in order to ensure bulk crystallization, the product is kept at 670-750 ° C for 10-70 minutes, then the temperature is increased at a speed of 75-320 ° C at 1 hour to 930-970 ° C and maintained at this temperature for 10-70 minutes, then cooled at a speed of 200-450 ° C per 1 hour.
