Molybdenum Fiber Refractory Materials
Molybdenum fiber refractory materials are specialized products of the ferrous metallurgy industry, developed and produced to meet the needs of special high temperature applications in industries such as aerospace, petrochemical, metallurgy and nuclear power. The molybdenum fiber refractory material, also known as molybdenum-silicon-boron (MSB) refractory material, is a new type of ceramic composite material developed by introducing the unique characteristics of molybdenum fibers into traditional refractory materials. It has excellent high temperature mechanical properties and corrosion resistance, which can be widely used in high temperature structural parts and various industrial furnace lining materials.
The structure of molybdenum fiber refractory material is composed of alumina ceramic particles and molybdenum fibers in a certain proportion and is processed through a special method. The molybdenum diffusion zone is composed of molybdenum fibers interspersed in a two-dimensional arrangement. The density of molybdenum fiber refractory material is relatively low, and the molybdenum fibers are evenly distributed in the ceramic particles. The lamellar structure formed by the molybdenum fibers plays an important role in the enhancement of the properties of the molybdenum fiber refractory material.
The thermal conductivity and flexural strength of the molybdenum fiber refractory material are significantly improved due to the addition of molybdenum fiber in the traditional refractory material. The molybdenum fiber refractory material has the advantages of high temperature resistance, corrosion resistance, creep resistance and thermal shock resistance, and can withstand temperatures up to 1350℃. The thermal conductivity of this material is 1.2-2.0 w/(m·k), and its flexural strength can be increased to more than 200MPa. At the same time, the molybdenum fiber refractory material has the advantages of light weight and low thermal expansion coefficient, which is beneficial to reduce the weight of the material and improve the high temperature thermal shock resistance.
In addition, due to the characteristics of small thermal expansion coefficient, good thermal conductivity and low thermal expansion coefficient, the molybdenum fiber refractory material has good effects on thermal shock absorption. This material can effectively improve the working environment temperature and reduce the thermal stress, which is helpful for extending the service life of the high temperature equipment and improving the efficiency of the equipment operation.
In summary, molybdenum fiber refractory material has the advantage of excellent high temperature mechanical properties and corrosion resistance, which has a wide range of applications in high temperature structural parts and industrial furnace lining materials. In addition, its small thermal expansion coefficient, good thermal conductivity and low thermal expansion coefficient also make it have good absorption of thermal shock, which is helpful to improve the working environment temperature and reduce thermal stress, thus extending the service life of high temperature equipment and improving its operation efficiency.
