Description
We mix nano-scale silica materials with some additives and use dry molding technology to make a micro-porous structure of high-efficiency thermal insulation board. It has a lower thermal conductivity than still air, excellent thermal insulation performance in high temperature environment, and obvious energy saving effect.

JHYRef Nano Insulation Board Products
Nano Microporous Insulation Board(JHY-400、JHY-550、JHY-950)
The nano microporous insulation board is manufactured from specially engineered inorganic refractory nano-powders using a patented dry-forming process. Its finely controlled nano-scale pore structure delivers an exceptionally low thermal conductivity—lower than that of still air—while maintaining excellent insulation performance and long-term stability under high-temperature operating conditions.This material serves as a key energy-saving component in modern high-temperature industrial furnace upgrades.
Insulation Mechanism of Low-Dimensional Nanostructures
The superior thermal insulation performance is achieved through the coordinated reduction of all three heat-transfer modes:
- Minimized solid-state conduction by selecting inorganic materials with inherently low thermal conductivity
- Extended heat-transfer paths via ultra-fine particle structures, reducing lattice thermal conduction
- Suppressed gas convection through nano-scale pores that restrict molecular movement, especially at high temperatures
- Reduced radiative heat transfer by incorporating opacifiers that reflect and absorb infrared radiation
- These mechanisms work synergistically to achieve exceptionally low conduction, convection, and radiation heat transfer at elevated temperatures.

Nano Microporous Insulation Board for Ladles–Model JHY1150
The JHY1150 Nano Microporous Insulation Board—also known as a nano-porous super-insulation material—is manufactured using nano-scale inorganic refractory powders through a dry-pressing process without the use of gel binders.
The material exhibits extremely low thermal conductivity, even lower than that of still air, delivering exceptional high-temperature insulation performance. It also provides significantly lower high-temperature linear shrinkage compared with traditional refractory materials, ensuring excellent dimensional stability.
Industry Background
The ladle is a critical vessel in steelmaking, and its thermal insulation performance directly influences process stability, molten-steel temperature control, and final product quality.
Traditional monolithic permanent linings have relatively high thermal conductivity, often resulting in ladle shell temperatures above 350°C, significant molten-steel temperature loss, and accelerated shell fatigue.
Application Advantages of Nano Microporous Insulation Board for Ladles–Model JHY1150
- Significant reduction in ladle shell temperature
- Lower molten-steel temperature drop during transfer
- Improved stability during continuous casting and subsequent processes
- Reduced energy consumption in LF refining
- Easy installation and removal with reduced labor intensity
