Metallurgical Grade
& Thermal Excellence

Engineered specifically for ferroalloy smelting and high-temperature industrial processing.

In the competitive landscape of the black metal smelting and rolling industry, our bulk coarse vermiculite stands as a global benchmark for thermal insulation efficiency. By utilizing premium raw minerals and a precision expansion process, we provide a material that ensures maximum energy retention and structural integrity within smelting furnaces.

Our technical advantage lies in the homogeneity of grain size and superior compressive strength. This allows operators to reduce heat loss significantly, lowering operational costs while extending the lifespan of critical smelting equipment through the superior protective properties of bulk coarse vermiculite.

Core Technical Pillars

The three fundamental advantages that define our metallurgical vermiculite performance.

01

Ultra-High Thermal Resistance

Engineered to withstand the extreme temperatures found in ferroalloy smelting processes.

  • Melting Point Control: Exceptional stability at temperatures exceeding 1200°C.
  • Low Thermal Conductivity: Minimizes heat dissipation to surrounding structures.
  • Shock Absorption: Reduces thermal expansion stress on furnace walls.
02

Structural Stability

Maintaining volume and density under intense industrial pressure and load.

  • High Compressive Strength: Resists collapsing under the weight of furnace linings.
  • Dimensional Stability: Minimal shrinkage during prolonged heating cycles.
  • Uniform Granularity: Ensures consistent gaps and predictable insulation layers.
03

Chemical Inertness

Resistant to corrosion and chemical reactions in harsh smelting environments.

  • Acid and Alkali Resistance: Stable in contact with diverse smelting fluxes.
  • Non-Combustible Nature: Zero flame propagation, ensuring plant safety.
  • Low Moisture Absorption: Prevents steam-induced cracking at high heat.
