How to avoid brand dependence in refractory brick exports and create a data-driven procurement mechanism

Why are your refractory bricks consistently failing prematurely? Many customers rely on brand labels, ignoring the actual performance data, leading to frequent replacements and downtime losses. This article explains in detail how to scientifically evaluate the comprehensive properties of magnesia-aluminum spinel refractory bricks using ISO test methods (such as ductility temperature, high-temperature flexural strength, and slag corrosion resistance tests), as well as cross-validate them with field-tested data. This will help industrial furnace engineers and purchasing managers create a data-driven quality selection mechanism, truly achieve rational material selection, reduce costs, and improve efficiency.
