CCEFIRE® DJM series insulating fire bricks are advanced refractory materials designed for direct flame contact in high-temperature industrial applications.
Combining lightweight, low thermal conductivity, and high refractoriness, these insulating bricks significantly enhance furnace efficiency and operational performance. They are particularly suitable for use in cracking furnaces, hot blast stoves, ceramic roller kilns, porcelain kilns, as well as lining materials for glass crucibles and various electric furnaces. With a wide temperature range from 1260°C to 1760°C, they are the ideal choice for improving furnace efficiency and extending service life.
In addition to standard sizes, CCEFIRE® lightweight insulating fire bricks can be customized to specific dimensions or shapes based on client requirements. Options include drilling, grooving, tapering, and arc-shaped cutting, enabling them to meet complex construction needs with precision. These bricks are easily adaptable to different furnace types, ensuring high accuracy and strength in construction.
In high-temperature industrial environments, corrosive agents are among the biggest threats to the service life of furnace linings. Alkali vapors, slag, acidic fumes, and chlorine-containing gases continuously attack insulation layers, leading to fiber embrittlement, powdering, or spalling. When insulation materials lack corrosion resistance, they not only lose thermal efficiency but also risk structural instability and […]

In high-temperature industrial applications, a ceramic paper gasket plays the dual role of sealing and insulation. It must not only operate stably for long periods at temperatures ranging from several hundred to over a thousand degrees Celsius, but also withstand mechanical stress and thermal shock during installation and operation. If tensile strength is insufficient, the […]

In high-temperature industrial furnaces and heat treatment equipment, linings must not only withstand continuous thermal radiation but also resist furnace pressure fluctuations and hot gas erosion. If compressive strength is insufficient, boards may collapse, crack, or fail during long-term operation, directly compromising insulation performance and operational safety. Therefore, compressive strength has become a key indicator […]
