The nano-composite reflective insulation board is made of ultra-fine nano-SiO2 and high-temperature resistant ceramic fibers as raw materials, with reflective aluminum foil as the base material, and is formed by a single-layer composite structure through a continuous coating, composite pressing and baking process. Its thermal conductivity is even lower than of stagnant air, and its insulation performance is about 4-6 times better than that of traditional insulation materials. It is one of the best insulation and heat insulation materials far.

Safe and environmentally friendly - a combination of pure inorganic materials, good thermal stability, no harmful substances released.

Economic analysis — The price is more than 50% lower than that of foreign counterparts, and it is 10-30% more energy-efficient than conventional materials.

Product physicochemical indicators

Product use effect

Reduce the thickness of the insulation layer

Since the insulation layer can be significantly thinned, the insulation layer can be lightened, and the volume of the furnace equipment can be increased

Reduce heat storage

Reduce the heat storage of the insulation layer, and significantly shorten the heating time of the kiln.

Therefore, not only can energy-saving effects be achieved, but also the effects of improving productivity and easy temperature control can be achieved.

Reduce heat dissipation

Since the thermal insulation effect can be achieved with thinner insulation materials, the heat dissipation surface area can be reduced, significantly reducing heat loss. Therefore, the surface temperature the kiln can be lowered, and the working environment can be improved.

Temperature equalization

The effect of reducing and loss can make the temperature achieve uniformity to the maximum extent. The result can make the metal solution, glass solution and other heat treatment in the kiln achieve more uniform temperature and improve the quality of the products.

Reduce costs

This is the most direct economic benefit, by reducing heat loss, extending the life of the ladle, improving the deformation of the steel shell of the ladle etc., the cost per ton of steel can be reduced by a few to tens of yuan.

Low temperature steel delivery

The essential foundation for low-temperature steel tapping is that the temperature drop during the subsequent transfer process of molten steel is relatively small. However, compared with and other developed countries, the steel tapping temperature in China is still 25-50 ℃ higher. Low-temperature steel tapping can improve the efficiency of the latent heat of the converter, reduce heat loss, and reduce the content of inclusions in molten steel. Reduce equipment thermal and chemical erosion and many other advantages.

Energy conservation and emission reduction

By using nano-composite reflective insulation board, the temperature of the outer wall of the steel ladle can be greatly reduced, which significantly reduces the heat loss the steel ladle transfer cycle, saves a lot of energy and reduces a lot of carbon dioxide.

Generalizability

Steel industry: Ladle, tundish, converter, electric furnace, iron ladle, torpedo can, etc. can be used

Aluminum industry: electrolytic cell, smelting furnace, vacuum ladle, insulation furnace, flow slot, etc.
