Изобретение относитс к огнеупорной промышленности и может быть использовано дл изготовлени плотных корундовых изделий.The invention relates to the refractory industry and can be used to make dense corundum products.
Известна шихта на основе дистенсиллиманита , корунда и св зки.Known charge based on dysthesillimanite, corundum and binder.
Цель изобретени - повысить плотность и термостойкость огнеупорных изделий.The purpose of the invention is to increase the density and heat resistance of refractory products.
Это достигаетс тем, что в качестве св зки используют кварцевый песок при следуюш,ем соотношении компонентов, вес. %:This is achieved in that quartz sand is used as a binder at the next component ratio, weight. %:
Корунд80-88Korund80-88
Дистенсиллиманит10-14Distensillimanit10-14
Кварцевый песок2-6.Quartz sand 2-6.
Пример. Корунд измельчают на зерна менее 2 мм, Дистенсиллиманит и кварцевый песок измельчают на зерна менее 0,06 мм и составл ют шихту в % соотношении соответственно 84, 12, 4.Example. Corundum is crushed for grains less than 2 mm, Distansillimanite and quartz sand are crushed for grains less than 0.06 mm and the mixture is in% ratio, respectively 84, 12, 4.
Компоненты смешивают, увлажн ют, прессуют при удельном давлении 1000 кгс/см и обжигают при 1750° С с выдержкой 6 час. Полученные издели обладают следуюш,ими свойствами:The components are mixed, moistened, pressed at a specific pressure of 1000 kgf / cm and calcined at 1750 ° C with a holding time of 6 hours. The resulting products have the following properties:
Плотность, ,20Density, 20
Термостойкость (теплосменыHeat resistance (heat exchangers
