Hengrui Ceramic Fiber

In industrial furnace applications, ceramic fiber, specifically aluminum silicate refractory fiber, has become a critical material for energy-saving upgrades. This is due to its exceptional thermal insulation properties and high-temperature resistance. Among these, aluminum silicate refractory fiber stands out for offering improved insulation performance. Traditional refractory materials are heavy with high heat storage. This causes slow furnace heating and excessive energy consumption. By contrast, ceramic fiber's lightweight nature (only 1/5 the density of traditional materials) and low thermal conductivity (0.15-0.21 W/m·K at 1000°C) can significantly reduce furnace wall heat loss by over 30%. It can also shorten heating time and enhance production efficiency. Aluminum silicate refractory fiber provides significant advantages in modern engineering.

Three Core Advantages of Choosing HENGRUI:

  1. Ultra-High Temperature Stability
    Hengrui's polycrystalline ceramic fiber boards (e.g., HR1700 series) withstand temperatures up to 1700°C with thermal shrinkage ≤1% (tested at 1500°C). This far exceeds industry standards. It ensures long-term furnace operation without deformation or cracking. This is especially true when using aluminum silicate refractory fiber.
  2. Custom Engineering Capabilities
    For complex furnace structures, Hengrui provides vacuum-formed custom components and modular designs. These precisely match furnace chamber contours. This eliminates localized heat leakage from traditional material joints.
  3. Full Lifecycle Cost Reduction
    CE-certified Hengrui products contain less than 0.2% impurities with superior erosion resistance. This extends service life to over 3 times that of conventional fibers. Consequently, it reduces furnace downtime. It also boosts comprehensive energy savings by 40% due to the efficiency of aluminum silicate refractory fiber.

Case Validation:
After retrofitting a special steel manufacturer's heat treatment furnace with Hengrui ceramic fiber modules, the exterior wall temperature dropped from 180°C to 65°C. Meanwhile, natural gas consumption decreased by 28%, yielding annual energy cost savings exceeding 2 million yuan.
