Изобретение относитс к огнеупорной промышленности и может быть использовано в производстве изделий дл разлива цветных и черных металлов в качестве конструктивных элементов различных тепловых агрегатов и изделий дл тепловой изол ции.The invention relates to the refractory industry and can be used in the manufacture of products for bottling non-ferrous and ferrous metals as structural elements of various thermal units and products for thermal insulation.
Известна масса дл изготовлени термостойких теплоизол ционных изделий, включающа в свой состав стеклоткань, высокоглиноземистый цемент, огнеупорный заполнитель и воду, имеет низкую огнеупорность.The known mass for the manufacture of heat-resistant heat-insulating products, including glass fabric, high-alumina cement, refractory aggregate and water, has a low refractoriness.
С целью повышени огнеупорности изделий из этой массы, увеличени срока их службы в состав массы в качестве огнеупорного заполнител вводитс двуокись циркони при следующем соотношении компонентов (в вес. %):In order to increase the refractoriness of products from this mass, to increase their service life, zirconium dioxide is introduced into the composition of the mass as a refractory filler in the following ratio of components (in wt.%):
Стеклоткань12-28Fiberglass 12-28
Высокоглиноземистый цемент 20-56 Двуокись циркони 8-36High-alumina cement 20-56 Zirconia 8-36
ВодаОстальноеWaterEverything
Кроме того, масса содержит ускоритель твердени цемента.In addition, the mass contains a cement hardening accelerator.
Пустотелые издели указанного состава изготавливают путем наматывани на дерев нный шаблон стеклоткани с предварительно нанесенным на нее огнеупорным раствором . Монолитные издели изготавливают путем укладки лент стеклоткани одна на другую с предварительно нанесенными на них сло ми огнеупорного раствора.Hollow products of the specified composition are made by winding a glass fabric with a refractory solution previously applied to it on a wooden template. Monolithic products are made by laying glass fiber tapes one upon another with layers of refractory mortar previously applied on them.
Издели из предлагаемой массы используютс при более высоких температурах службы 1550-1600°С. Механическа прочность на 15-20% выше, чем у изделий из известной массы. Указанные преимущества достигаютс при сохранении одинаково высокой термостойкости и низкой теплопроводности композиционных изделий.Products from the proposed mass are used at higher service temperatures of 1550-1600 ° C. Mechanical strength is 15–20% higher than that of products of known mass. These advantages are achieved while maintaining the same high heat resistance and low thermal conductivity of composite products.
