Features of DJM Insulating Fire brick

Low Thermal Conductivity, with Good Thermal Insulation Effect
CCEFIRE® DJM insulating fire brick boasts low thermal conductivity, providing exceptional thermal insulation. This helps maintain stable temperatures within furnaces and thermal equipment, ensuring energy efficiency and reduced operational costs.
Low Heat Capacity for Enhanced Energy Savings
Thanks to its low thermal conductivity, CCEFIRE® DJM insulating fire brick has a low heat capacity. This means it accumulates minimal heat energy, demonstrating significant energy-saving effects, especially in intermittent operations where rapid heating and cooling cycles are common.
Low Impurity Content for High Refractory Performance
CCEFIRE® DJM insulating fire brick features very low levels of impurities, such as iron and alkali metal oxides. This characteristic enhances its refractory performance, making it highly resistant to high temperatures and chemical attacks. The higher aluminum content ensures the brick maintains its integrity and performance even in reducing atmospheres.
High Compressive Strength at Elevated Temperatures
CCEFIRE® DJM insulating fire brick exhibits high compressive strength under high temperatures. This ensures the structural integrity of the brickwork in furnaces and other high-temperature environments, providing long-term durability and reliability.
Precise Dimensions for Efficient Installation
The accurate appearance and size of CCEFIRE® DJM insulating fire brick speed up the brick-laying process, reducing the amount of refractory mortar needed and ensuring the strength and stability of the brickwork. This precision extends the life of the furnace lining and minimizes maintenance needs.
Customizable Shapes for Reduced Joints and Enhanced Efficiency
CCEFIRE® DJM insulating fire brick can be processed into special shapes, reducing the number of bricks and joints required in the construction. This customization improves the overall structural integrity and efficiency of the insulation, enhancing the performance and lifespan of thermal equipment.
