Claims (2)

1. Способ изготовления керамобетонных кварцевых сталеразливочных огнеупоров, включающий получение высококонцентрированной суспензии кварцевого стекла мокрым измельчением, центробежное формование при переменной скорости, сушку и упрочнение изделий, отличающийся тем, что для формования применяют суспензии плотностью 1,89 - 1,93 г/см3 в которые дополнительно вводят зернистый заполнитель из кварцевого стекла с размером частиц 0,1 -2,0 мм в количестве 30-45% (на сухое вещество), смешивают и формуют изделие, подвергая сушке и термообработке при 1150 - 1200°С.1. A method of manufacturing a ceramic concrete quartz steel-casting refractories, comprising obtaining a highly concentrated suspension of silica glass by wet grinding, centrifugal molding at variable speed, drying and hardening of products, characterized in that suspensions with a density of 1.89 - 1.93 g / cm 3 in which additionally introduce granular filler made of quartz glass with a particle size of 0.1 -2.0 mm in an amount of 30-45% (on a dry basis), mix and form the product, subject to drying and heat treatment at 1150 - 120 0 ° C. 2. Способ по п.1, отличающийся тем, что зернистый заполнитель перед его смешением с суспензией подвергается увлажнению сливом центробежного литья кварцевой керамики с плотностью 1,40 - 1,65 г/см3 до влажности 2-5%.2. The method according to claim 1, characterized in that the granular aggregate is subjected to moistening by centrifugal casting of quartz ceramics with a density of 1.40 - 1.65 g / cm 3 to a moisture content of 2-5% before being mixed with the suspension.
