石油化学炉用自己流動キャスタブルの溶融アルミン酸カルシウム
Fused calcium aluminate in self-flowing castables delivers measurably better flow, hot strength, and sulfur resistance than sintered grades in petrochemical furnace linings. This article explains the phase chemistry behind those gains, presents comparative performance data across key ISO test standards, and outlines the specification and sourcing criteria engineers need to qualify the material for critical applications.
