Temperature Grade 2800°F (1540°C)

CCEFIRE DJM28 insulating fire brick combines light weight, high strength, and ultra-low thermal conductivity to deliver durable thermal protection and energy efficiency in demanding environments. It performs exceptionally in steelmaking, refining ladles, non-ferrous metal electrolytic cells, petrochemical cracking furnaces, and high-temperature glass processes. By enhancing thermal efficiency and extending the service life of linings, DJM28 is the ideal solution for continuous high-intensity production.

CCEFIRE DJM Insulating Fire Brick is supported by two automated batching systems, five extrusion molding production lines, five cutting and processing lines, two high-temperature tunnel kilns with automatic temperature control, one high-temperature shuttle kiln, three press molding production lines, and two automatic batching lines for monolithic refractories, with an annual output of 20,000 tons of various refractory materials.

CCEWOOL's manufacturing facility covers 80,000 m2 and is equipped with over 60 advanced high-temperature insulation fiber production lines, delivering an annual capacity in excess of 300,000 tons.

26 production lines dedicated to CCEWOOL ceramic fiber blankets. Products range from 1100–1430 °C ceramic fiber blankets to PUREWOOL ceramic fiber blankets, hydrophobic ceramic fiber blankets, and ceramic fiber aluminum foil blankets.

2 production lines for CCEWOOL bio soluble(Low Biopersistent) fiber blankets, offering 1200 °C low-bio soluble blankets, an innovative 1300 °C grade, and aluminum foil fiber blankets.

1 production line for CCEWOOL polycrystalline wool fiber blankets, with products rated up to 1600 °C.

Equipped with three fully automated CCEWOOL ceramic fiber board production lines, one fully automated CCEWOOL bio soluble fiber board line, and one CCEWOOL polycrystalline wool fiber board line, we have also independently developed a "2-hour deep-drying" system. Our product range includes ultra-large boards up to 1.2 × 2.4 m, ultra-thin boards with thicknesses of 3–10 mm, and high-density boards with bulk densities of 800–1000 kg/m3. We also manufacture classic series such as ultra-low thermal conductivity boards, hydrophobic boards, and aluminum foil fiber boards.

Equipped with two fully automated CCEWOOL high-temperature insulation fiber paper production lines, we offer a comprehensive range of papers to suit varying temperature requirements: standard ceramic fiber paper, high-alumina and zirconia-enhanced grades, and low-bio-soluble fiber paper, as well as our in-house innovations—flame-retardant ceramic fiber paper and expansion ceramic fiber paper.

Includes seven fully automated CCEWOOL high-temperature insulation fiber module production lines, capable of fabricating bespoke shapes per customer drawings—standard ceramic fiber modules, precision-cut blocks, and folded blocks. We further produce bio soluble fiber modules, polycrystalline wool fiber modules, composite fiber modules, and monolithic fiber modules, delivering a complete high-temperature insulation module system.

With over ten CCEWOOL high-temperature insulation fiber textile production lines, we manufacture a wide variety of ceramic fiber and bio soluble fiber yarns, fabrics, tapes, and ropes to meet diverse application needs.

Our eight fully automated CCEWOOL high-temperature insulation fiber cutting and grinding machines, alongside five high-temperature curing kilns, enable the custom production of tubes, cones, domes, and box-shaped components per customer specifications. Products are available in both organic and inorganic fiber variants and may be surface-coated with vacuum-form hardeners or refractory mortars. Temperature ratings span from 1260 °C to 1800 °C.
