Abstract

This article reviews the literature concerning high spinel bricks and magnesia spinel bricks for application in the glass industry. The characteristics of RUBINAL ESP, a RHI developed new spinel-bonded magnesia brick brand, are reported. Based on industrial experience, RUBINAL ESP can be recommended for checkers in the condensation zone of regenerators where high amounts of Na2SO4 and SO3 are expected.

Keywords
