Microporous Board for Steel Industry
Microporous boards are specifically engineered for high-temperature industrial applications, offering exceptional thermal efficiency with a conductivity lower than that of still air.
- Thermal Conductivity Lower Than That of Still Air
- Excellent High-Temperature Stability
- Lightweight and Efficient
- Environmentally Friendly and Non-Toxic
- Resistance to Thermal Shock
What is Microporous Board?
A microporous board is a high-performance insulation material made from ultra-fine, nanoporous silica, often enhanced with specific additives to reduce all forms of heat transfer. Its unique structure gives it a thermal conductivity even lower than that of static air, providing 3-6 times more effective insulation compared to traditional materials like mineral wool, perlite, and calcium silicate. Ideal for extreme temperatures, microporous boards excel in applications that demand exceptional thermal efficiency, making them highly suitable for various industrial uses, including aluminum, glass, and steel production. Additionally, they are lightweight, thin, and non-combustible, making them easy to install and environmentally friendly.

Application of Microporous Boards in the Steel Industry
In the steel industry, microporous boards provide crucial insulation solutions tailored to withstand high temperatures and extreme conditions found in steel production. Engineered to enhance thermal management and energy efficiency, these boards are used in ladles, tundishes, reheat furnaces, and electric arc furnaces. Their superior insulation helps steel manufacturers achieve higher energy savings, improved process safety, and optimized performance. With high resistance to thermal shock, microporous boards ensure stable, long-lasting insulation, contributing to cost-efficiency and safety in demanding industrial settings.
Key Features of Microporous Boards
Exceptional Thermal Conductivity: The nanoporous structure effectively reduces conduction, convection, and radiation, achieving thermal conductivity lower than still air and providing up to six times the insulation of conventional materials.
Superior Heat Stability: Performs reliably at high temperatures, remaining effective up to 1200°C.
Lightweight and Space-Saving: Provides robust insulation while being over 50% lighter than traditional materials, perfect for compact applications.
Environmentally Friendly: Free of toxic substances and harmful fibers, it is recyclable and environmentally safe.
Resilient to Thermal Shock: Built to withstand abrupt temperature changes, ensuring stability in demanding environments.
Molding Method
Microporous boards are molded using machine press molding (primarily for boards):
- Unlike bricks, microporous boards require no drying or sintering.
- After pressing, the boards can be cut to meet various size specifications.
- For glass fiber cloth-covered types, there are two production methods:
a. The powder is placed into a fiberglass bag and then pressed, resulting in cambered edges.
b. After pressing and molding, the boards are wrapped and cut, creating right-angle edges.
What makes microporous board thermal conductivity lower than still air?
Microporous insulation materials leverage their advanced nanoporous structure and the synergy of special additives to reduce heat transfer across a wide temperature range. Unlike traditional insulation options like mineral wool, perlite, insulating bricks, calcium silicate, and ceramic fibers, as well as aerogel felts, these materials provide superior insulation. Impressively, microporous boards can maintain thermal conductivity levels lower than static air across various conditions.
Core Benefits:
- Nanoscopic Structure: Reduces heat conduction by minimizing surface contact.
- Nanoporous Composition: Ultra-fine pores around 20nm trap gas, nearly eliminating convection inside.
- Anti-Infrared Properties: Blocks and reflects infrared radiation, effectively controlling heat transfer at high temperatures.
With these features, microporous boards provide unmatched thermal efficiency, making them ideal for demanding industrial and high-temperature applications.
Multiple Surface Covering Choices
Depending on factors like product type, operating temperature, handling requirements, and environmental conditions, microporous boards are available with various standard covering materials. These include:
– Aluminum Foil Covering
– Aluminum Foil Cloth Covering
– POF (Polyolefin) Film Covering
– Non-woven Fabric Covering
– Fiberglass Cloth Covering
Each covering material is chosen to suit specific application needs, ensuring optimal performance and durability in diverse industrial and operational settings.
