О технологии производства и службе кварцевых сталеразливочных огнеупоров. Часть 1. Технологические особенности

摘要

Production conditions are specified for quartz refractories withenhanced endurance. The most important technological factor isproduction and application of extremely concentrated suspensions offused quartz(moisture 12-13%) having high polydispersity in slip orcentrifugal casting. A method of pressing the ceramoconcrete-basedmixtures makes it possible to reduce the porosity of as-formedsemiproduct to 7-12%. Analysis of the dynamics of quartz refractoryproduction at the Pervoural'skii Dynas Works revealed a 4-foldincrease in the refractory production over a 4-year period.
