This report conducts a comprehensive inspection on mullite refractory materials used for pusher plates and saggars, in accordance with the international standard ISO 9001 quality management system and GB/T 3002-2017 "Test Method for High-Temperature Flexural Strength of Refractories". The test results verify the excellent performance of the materials in terms of high-temperature stability, mechanical strength and thermal shock resistance, which fully meet the application requirements under high-temperature working conditions of industrial kilns.
Mullite refractory materials are not only the basic materials for key components of kilns, but also the core elements to ensure the long-term safe operation of heat treatment equipment and improve energy utilization efficiency.
