Recently, CCEFIRE® successfully shipped a 40HC container of CCEFIRE® DJM26 Insulating Fire Brick (1430°C / 2600°F) to a key customer in South Africa with seven years of cooperation. The customer has long served the high-temperature industrial furnace and heat treatment equipment sector and places high requirements on lining materials in terms of load-bearing capacity, operational stability, and furnace temperature control.
Years of continued repeat orders stem from the stable compressive and flexural strength demonstrated by CCEFIRE® DJM26 Insulating Fire Brick under real operating conditions. Even under high temperatures and long-term thermal cycling, the bricks maintain structural integrity, providing reliable support for continuous production.
In high-temperature industrial furnaces, insulating bricks not only provide thermal insulation but also bear the lining’s self-weight, structural loads, and repeated thermal expansion and contraction stresses. Designed for insulation layers in medium- to high-temperature furnaces, CCEFIRE® DJM26 Insulating Fire Brick delivers reliable compressive and flexural strength through stable formulation and forming control, while maintaining excellent insulation performance.
During raw material selection and formulation, key components are precisely proportioned, and low-melting impurities such as alkali metals are controlled to below 1%. This reduces the risk of deformation or cracking during long-term service and ensures overall stability in practical applications, reflected in:
Stable lining structure under long-term high temperatures and sustained loads
Reduced risk of localized damage and maintenance caused by strength degradation
More reliable support for furnace temperature control and process operation
To ensure long-term performance consistency of DJM26 Insulating Fire Brick, CCEFIRE® uses an 88-meter fully automated tunnel kiln. A continuous and well-controlled firing regime allows the bricks to develop a stable, repeatable microstructure during sintering.
This stable manufacturing control ensures consistent compressive and flexural performance, delivering practical operational value through:
Consistency in compressive and flexural strength across different production batches
Avoidance of potential risks to furnace linings caused by performance fluctuations
Through continuous control of compressive and flexural properties, CCEFIRE® DJM26 Insulating Fire Brick maintains stable performance under long-term high-temperature operation. For industrial furnaces requiring continuous operation and demanding high equipment stability with extended maintenance intervals, this stable and predictable performance provides reliable protection for furnace lining systems.
