polycrystalline mullite fiberI believe there are still many people who are not clear about these issues, so today I will explain to you about the knowledge related to it! Hope it can bring good help to the relevant people.

Polycrystalline mullite fiber is widely used in metallurgy, machinery, ceramics, electronics, petrochemical, aerospace and other fields of high temperature industrial furnace and other thermal equipment lining insulation. In this way, it can naturally achieve the purpose of saving energy and increasing production, reducing the temperature difference in the furnace, improving product quality, reducing spare parts consumption, extending the service life of the furnace, and improving the working environment. Of course, this is mainly because the polycrystalline arable fiber is loose and porous, has the characteristics of low thermal conductivity and high blackness coefficient, coupled with its high temperature stability and good quenching and heat resistance. At present, polycrystalline mullite fiber is widely used in the working face of high temperature furnace, and the energy saving effect is very significant. Therefore, the energy-saving effect of polycrystalline mullite fiber used in high-temperature furnace windows is better than that of ordinary refractory bricks or high-temperature coatings, and the energy saving is much greater than the heat loss. Another reason is not only the heat loss is reduced, but also the convective heat transfer from the furnace gas to the furnace wall is strengthened. The polycrystalline mullite fiber makes the furnace wall obtain more heat, and then transfers it to the material through radiation, thereby increasing the heating speed of the material And production capacity.

polycrystalline mullite fiberThe energy-saving effect for high-temperature furnace windows is better than ordinary refractory bricks or high-temperature coatings. The amount of energy saving is much greater than the heat loss, which is not only due to the reduction of heat loss. At present, the main reason is that the convective heat transfer of the furnace gas to the furnace wall is strengthened, so that the furnace wall obtains more heat, and then passes to the material through radiation, thereby improving the heating speed and production capacity of the material. Of course, the polycrystalline mullite fibers are still loose, soft and elastic at high temperatures. Polycrystalline mullite fiber has good thermal stability, small shrinkage at high temperature and low heat capacity. Low thermal conductivity, good thermal insulation performance. Now it also has good chemical stability and corrosion resistance. Good thermal shock resistance and sound absorption performance. Easy to install. In addition, the regenerative heating furnace adopts polycrystalline mullite fiber, which prolongs the service life of the furnace top and reduces the maintenance cost, reduces the heat loss of the furnace body and improves the thermal efficiency, shortens the heating and cooling speed before and after rolling, and improves the operation rate and yield rate. After years of development and hard work, we have been in this industry. Has a certain degree of visibility, so welcome and friends from all over the country to establish long-term cooperative relations.
