In walking beam reheating furnaces and other metallurgical equipment, sealing materials operate under repeated heating, cooling, and mechanical disturbance. Furnace temperatures fluctuate cyclically between 1100–1250°C, causing continuous stress accumulation along the sealing interfaces. Conventional fiber ropes often become brittle, powdery, or fractured after only a few hundred thermal cycles, resulting in seal failure, heat leakage, rising energy consumption, and more frequent maintenance.
CCEWOOL® insulation ceramic rope are engineered specifically for such severe thermal-shock conditions. Their performance is rooted in high-purity raw materials, precise fiber fineness control, structural design, and intelligent manufacturing—together providing exceptional thermal-shock resistance and long-term sealing stability under extreme operating conditions.
How do CCEWOOL® insulation ceramic rope deliver longer-lasting, more stable high-temperature sealing in walking beam reheating furnaces?
CCEWOOL® insulation ceramic rope are made from high-purity alumina and silica sourced from our own mineral deposits, with impurity levels consistently below 1%. High-purity fibers resist crystallization at high temperature, preventing brittleness and powdering caused by phase changes. As a result, CCEWOOL® insulation ceramic rope maintain flexibility and toughness even after long-term exposure to high temperature and intense thermal cycling—fundamentally enhancing their thermal-shock resistance and making them ideal for harsh reheating-furnace environments.
CCEWOOL® uses imported high-speed centrifuges operating at 11,000 r/min to produce fibers with a uniform diameter of 2–3 μm. Finer and more consistent fibers disperse thermal stress rapidly throughout the fiber network, preventing localized stress concentration and breakage. This greatly improves strength retention during rapid heating and cooling, giving CCEWOOL® insulation ceramic rope superior thermal-shock performance in walking beam furnaces, enabling longer-lasting seals and lower overall heat loss.
CCEWOOL® insulation ceramic rope use a tightly braided, three-dimensional fiber structure that preserves compressible, recoverable internal space. When the furnace door opens, the structure expands or contracts, or the temperature fluctuates sharply, the rope absorbs the resulting stress and quickly returns to its original form. This allows the rope to maintain geometric stability without loosening or deformation, even under high-frequency stress, further supporting its strong thermal-shock resistance.
Stainless-steel wire reinforcement gives the rope higher tensile strength and abrasion resistance, ensuring structural integrity during prolonged thermal cycling. The wire is co-woven with the fibers to prevent unraveling or collapse during operation. This significantly enhances durability under extreme thermal-shock conditions and extends service life far beyond that of ordinary fiber ropes.
CCEWOOL® integrates its self-developed Ceramic Fiber Products Intelligent Manufacturing Management System V1.0 into production. By monitoring twist, tension, fiber distribution, and temperature in real time, the system automatically adjusts process parameters to ensure consistent density, elasticity, and structural uniformity along every meter of rope. Consistency ensures predictable thermal-shock performance, allowing every batch to operate reliably in harsh industrial conditions.
CCEWOOL® insulation ceramic rope enhance sealing and energy efficiency in walking beam reheating furnaces
Operational data from multiple steel plants show that CCEWOOL® insulation ceramic rope maintain flexibility and structural integrity even after thousands of thermal-shock cycles. Furnace-door sealing areas remain stable without powdering or detachment, heat leakage is significantly reduced, shell temperatures drop, and overall heat loss decreases by approximately 10–12%. Maintenance intervals are extended, reducing downtime and improving overall furnace efficiency.
With high-purity materials, ultra-fine fiber structure, 3D braided construction, reinforced design, and intelligent manufacturing, CCEWOOL® insulation ceramic rope maintain flexibility, stability, and durability under extreme thermal cycling. Their outstanding thermal-shock resistance not only ensures reliable high-temperature sealing but also enhances furnace safety, energy efficiency, and operational stability—making them a preferred sealing material for high-temperature industrial equipment.
