THERMORESISTANT FIRECLAY REFRACTORY

摘要

This fire-proof agent is used for technical purposes in multiple alternations of high and low temperatures. It has a high thermal resistance in thermal exchanges without content of multi-fractional chamotte, and enhanced mechanical strength without variations in the existing technology. The fire-proof agent consists of between 68 and 72% chamotte, modified with barium oxide, and between 28 and 32% bonding modified with barium oxide. The modified chamotte is a kaolin- and barium-containing component, where the proportion of barium oxide to the bialuminium trioxide is between 0.10 and 0.21, while the proportion of barium oxide to silicon dioxide - between 0.09 and 0.18. The modified bonding is a mixture of kaolin and barium-containing component, while the proportion of barium oxide to bialuminium trioxide is between 1.4 and 1.6, and the proportion between barium oxide to silicon dioxide - between 1.25 and 1.32.
