Refractory Protective Shells

Refractory protective shell is a kind of shell used to protect the refractory material, usually used to wrap in the surface of the refractory material, play a protective role. Refractory protective shell material variety, different materials have different characteristics and uses, choose the right material to improve the service life of the refractory material and the effect is critical.

Generally speaking, the refractory protective shell material should have the following characteristics:

1. high temperature: refractory protective shell needs to be able to withstand high temperature environment, will not melt or deformation due to high temperature, to ensure the normal use of refractory materials.

2. corrosion resistance: refractory materials are often used in corrosive environments, so the refractory protective shell material needs to have a certain degree of corrosion resistance, will not be affected by corrosion.

3. Abrasion resistance: refractory protective shell needs to have a certain degree of wear resistance, can resist external friction and collision, to extend the service life.

4. Good sealing: refractory protective shell needs to have good sealing, can effectively refractory material wrapped in the internal, prevent the external environment on its impact.

Common refractory protective shell materials include:

1. metal materials: such as stainless steel, aluminum alloy and other metal materials, with good high temperature and corrosion resistance, suitable for protection in high temperature environment.

2. ceramic materials: such as alumina, aluminum silicate and other ceramic materials, with excellent high-temperature resistance and wear resistance, suitable for high-temperature and corrosive environments.

3. refractory brick material: one of the materials commonly used in refractory protective shells, with good high temperature resistance and corrosion resistance, and significant protection effect.

4. high-temperature resistant plastic materials: such as PTFE, polyphenylsulfone and other high-temperature resistant plastic materials, with good high-temperature resistance and corrosion resistance, is one of the choices of refractory protective shell.

In general, the choice of suitable refractory protective shell material is very important, only in different environments and requirements to choose the right material to effectively protect the refractory material, to extend its service life. I hope the above content can help you.
