(54) ШИХТА ДЛЯ ИЗГОТОВЛЕНИЯ ЭЛЕКТРОПРОВОДНЫХ ОГНЕУПОРНЫХ ИЗДЕЛИЙ(54) CHARGE MECHANISM FOR THE MANUFACTURE OF ELECTRICAL WIRES REFRACTORY PRODUCTS
tt
Изобретение относитс к стекольной промышленности и может быхь-использовано при изготовлении электропроводных огнеупорных изделий, например , электродов в варочных част х печей дл электроварки стекол, электродов дл подогрева стекломасс в фидерах, чехлов дл термопар, брусьев дл протоков, барботажных трубок, мешалок и каплеобразующих деталей .фидеров.The invention relates to the glass industry and can be used in the manufacture of electrically conductive refractory products, for example, electrodes in cooking parts of electric glass ovens, electrodes for heating glass mass in feeders, cases for thermocouples, duct bars, bubbling tubes, agitators and dripping parts .feders.
Известна шихта дл изготовлени огнеупорных изделий, содержаща , вес.%:The known charge for the manufacture of refractory products, containing, wt.%:
Двуокись олова 90-95 Хлористое олово 5-10Tin dioxide 90-95 Tin chloride 5-10
Из шихты такого состава прессуют брикеты, обжигают и измельчгиот, отдел ют фракцию с размером зерен 10 ,5 мм, прессуют издели и спекаютBriquettes are pressed from the mixture of this composition, burned and ground, the fraction with a grain size of 10, 5 mm is separated, products are pressed and sintered
при 1.at 1.
Однако огнеупорный материгш из шихты облсщает повышенным удельным сопротивлением, пониженными механической прочностью и плотностью, причем последние свойства обусловлены наличием в шихте спеченых зерен крупных фракций.сырой двуокиси олова , а также недостаточной температурой спекани материала.However, the refractory material from the charge has an increased specific resistance, lowered mechanical strength and density, the latter properties being due to the presence of sintered grains of large fractions of raw tin dioxide in the mixture, as well as an insufficient sintering temperature of the material.
Известна Шихта дл изготовлени электропроводных и огнеупорных изделий , содержаща спеченую SnO с добавками , %: СиО 0,1-0,5; ZnO 0,5-1,0, Sb20-5 0,7-1,2-.The known mixture for the manufacture of electrically conductive and refractory products containing sintered SnO with additives,%: CuO 0.1-0.5; ZnO 0.5-1.0, Sb20-5 0.7-1.2-.
Оформленные издели из такой массы по керамической технологии (прес0 сование, пластическое формование, лликерное литье) спекают в течение 18-24 ч при 1450-1460С 2.Decorated products of such a mass are cemented by ceramic technology (pressing, plastic molding, lye casting) for 18–24 h at 1450–1460С 2.
Однако электропроводный и огнеупорный материал, полученный из ука5 занной шихты,. обладает пониженным удельным электросопротивлением, высокой стеклоустойчивостью, но имеет низкую термостойкость и большую нестабильную усадку при обжиге (100 12,0%), создающую трудности в получении бездефек- ных изделий заданных размеровiHowever, electrically conductive and refractory material obtained from this mixture. has a low electrical resistivity, high glass resistance, but has low heat resistance and a large unstable shrinkage during firing (100–12.0%), which creates difficulties in obtaining defect-free products of specified sizes
Известна также шихта дл изготовлени огнеупорных изделий, содержаща Also known charge for the manufacture of refractory products, containing
5 сырую двуокись олова, добавки окиси меди, окиси цинка, окиси сурьмы и обожженную двуокись олова Сз.5 raw tin dioxide, additives of copper oxide, zinc oxide, antimony oxide and calcined tin dioxide Сз.
Из-дели , изготовленные из такой шихты, имеют высокую термостойкость, Made of such a mixture, have a high heat resistance,
0 но отличаютс повышенным удельным0 but differ in increased specific
электросопротивлением, это ограничивает их применение,в качестве электродов . Кроме того, издели обладают, недостаточно высокой стеклоустойчивостью и механической прочностью. . Из полученного материала невозможно изготавливать тонкостенные издели , например чехлы дл термопар вследствие содержани в шихте крупных зерен размером более 0,1 мм (0,1-2-мм),electrical resistance, it limits their use as electrodes. In addition, the products have not enough high glass stability and mechanical strength. . It is not possible to produce thin-walled products from the material obtained, for example, covers for thermocouples due to the content of large grains larger than 0.1 mm (0.1-2 mm) in the mixture,
Наиболее близкой к предлагаемой по технической сущности и достигаемому результату вл етс шихта 4, содержаща , вес.%: . .Closest to the proposed technical essence and the achieved result is the charge 4, containing, wt.%:. .
