摘要
The properties and performances of high purity corundum bricks for the refractory linings of the gasifiers in the ammonia and ethene synthesis and carbon black reaction furnaces in China are described.The high purity corundum bricks are characterized by high refractoriness,hot strength,dimensional stability and chemical inertness at elevated temperature,Their performances in the gasifiers and carbon black furnaces are very satisfied ,The failure mechansims of the refractory lining are discussed on the basis of the petrographic analysis.
