  • About author:Ding Qiang was born in 1987. He graduated from University of Science and Technology Beijing in 2013 and obtained his master’s degree of Materials Science majored in refractories. Since then, he has been working in RHI Magnesita as a Research & Development engineer, focusing on the production and field application of magnesia-based products in different industries.

Abstract:

A new type of magnesia spinel brick containing a novel flexibilizer was developed. The publication presents an investigation on its chemical composition, physical properties and cement clinker resistance. Compared to conventional magnesia spinel bricks, the new brick type shows reduced amounts of alumina, significantly improved hot properties and resistance against cement clinker attack whilst keeping its textural flexibility on the same level. Field trials revealed satisfactory results and confirmed the novel flexibilizer concept.

Key words: magnesia spinel brick, flexibilizer, cement clinker resistance
