200kg bulk density ceramic fiber rope 50 * 60mm for steel plant

Apr 24, 2026

200kg bulk density ceramic fiber rope 50 * 60mm for steel plants? 200kg/m ³, 50 × 60mm flat square ceramic fiber rope for steel plants is a specialized flexible sealing material with low density, high elasticity, large cross-section, high temperature resistance, and vibration resistance; Perfectly adapted to the wide gap sealing and insulation of heating furnace doors, expansion joints, and flue flanges, the sealing effect, construction convenience, and service life are superior to high-density hard ropes, making it the preferred choice for high temperature gap sealing in steel mills with high cost-effectiveness.

What are the core functions of ceramic fiber rope in steel plants?

1. Wide gap flexible seal (core application)
2. Efficient insulation and heat preservation
3. Anti thermal shock+anti furnace body vibration (essential for steel mills)
4. Resistant to harsh working conditions in steel mills

What are the application areas of ceramic fiber rope in steel plants?

1. Sealing of heating furnace/heat treatment furnace door
Tighten and seal the large gaps around the furnace door, fill the gaps around the upper and lower sides of the furnace door and the observation hole (800-1000 ℃)
2. Furnace expansion joint/expansion joint filling
Longitudinal/transverse thermal expansion gaps of furnace top, furnace wall, and furnace bottom (most commonly used by steel mills in 50 × 60 specifications)
3. High temperature flue and waste heat pipeline flange sealing
Hot air flue, large mouth flange of flue gas pipeline, and wrapped sealing around valves (400-900 ℃)
4. Walking beam furnace, annealing furnace, steel rolling heating furnace
Sealing and insulation of furnace body joints, burner edges, and furnace roller through wall gaps
5. Insulation and sealing around the ladle, molten iron tank, and intermediate ladle
The edge of the tank mouth and the cover plate are sealed, buffered, and insulated

200kg ceramic fiber rope with a density of 50 * 60mm for steel plants? The 50 * 60mm ceramic fiber rope for steel plants belongs to the specification of square braided rope (flat rope), with a rectangular cross-section. Due to the large sealing contact surface, this type of rope is particularly suitable for areas such as furnace door edges, flange planes, rectangular gaps, etc. in steel plants that require large-scale sealing.
