详细
The effect of nonisothermal heating temperature in the range 1100 – 1500°C on shrinkage indices and and degree of cristobalitization is studied for quartz steel-pouring refractory specimens with a ceramic concrete structure. Cristobalite formed at elevated temperature has a reduced (150 – 220°C) transition temperature into the low-temperature form. Quartz steel-pouring refractories with a ceramic concrete structure have good thermal shock resistance, and in contrast to corundum-graphite refractories, requiring preliminary high-temperature heating, may operate without the latter (“cold start”).
