In the steel industry, equipment such as heat treatment furnaces, walking beam furnaces, and roller hearth furnaces are subject to extreme temperatures and frequent thermal cycling during long-term operation. Traditional heavy back-up insulation materials often fall short due to insufficient insulation performance, high thermal inertia, and frequent maintenance, resulting in slow heat-up rates, excessive energy loss, and reduced productivity—hindering the industry's drive for cost control and energy savings.

Low Thermal Conductivity and Excellent Thermal Shock Resistance: CCEWOOL Refractory Insulation Board for High-Temperature Back-Up Applications

To solve the issue of poor insulation performance and structural instability in furnace back linings, CCEWOOL refractory insulation board offers low thermal conductivity, excellent thermal stability, and outstanding resistance to thermal shock. Even at temperatures above 1000°C, the board maintains its structural integrity without cracking or powdering. It is especially well-suited for furnace walls, roofs, and hot-air ducts, where thermal loads are high and temperature fluctuations are frequent—ensuring better system insulation performance and durability.

High-Purity Materials + Automated Forming + Uniform Sintering: CCEWOOL Delivers High-Strength, Stable Ceramic Fiber Boards

CCEWOOL refractory insulation boards are made using high-purity spun fiber produced in-house, combined with fully automated vacuum forming and intelligent drying and sintering systems. This ensures boards are dense, dimensionally accurate, and surface-smooth. By fine-tuning slurry formulas and forming pressures, the boards gain enhanced compressive and flexural strength, meeting the steel industry's demand for long-term performance under high-temperature conditions in large-scale thermal equipment.
