What are the lining materials of refractory kiln?

There are many kinds of high-temperature industrial kilns. Different functional kilns use different types of refractory materials and different material quality. High temperature industrial kilns are lined with refractory materials to protect the normal operation of high temperature kilns. What are the common refractory materials for the lining of high-temperature industrial kilns?

Reasonable refractory lining structure is the basis of stable production of high-temperature industrial kilns. Generally speaking, the commonly used refractory materials for the lining of high-temperature industrial kilns include: refractory brick masonry, unshaped refractory materials, thermal insulation ceramic fiber refractory materials and other refractory materials.

1.The choice of refractory brick masonry for industrial kilns is to use refractory bricks and refractory slurry as the lining, which is the most widely used lining structure of kilns. When selecting refractory bricks to construct the lining of the kiln, it is necessary to select refractory bricks of appropriate materials and specifications according to the structure of the kiln body to build the lining.

2.Unshaped refractory material is a popular refractory material for lining industrial kilns. The main products are fire-resistant castables, fire-resistant spraying coatings, fire-resistant ramming materials and so on.

During the construction of refractory castable, the refractory materials can be mixed according to the requirements and then poured to the parts requiring construction. It has good fluidity, convenient construction, short construction time, good use effect and wide application range. It can also be used in places where refractory bricks are difficult to build.

During the construction of fire-resistant spray coating, the selected spraying tools can be sprayed from multiple angles and unlimited positions. High quality refractory materials are selected to construct and spray the kiln lining as the kiln lining.

The construction methods of refractory castable and refractory spray coating are different, and the essential requirements for refractory materials are slightly different. For example, the fire-resistant castable requires good fluidity and the fire-resistant spray coating requires low rebound rate. However, in order to better integrate the spraying paint with the kiln lining, it is generally necessary to install anchors on the kiln lining during construction, so that the construction effect after spraying is good.

Fire resistant ramming materials are generally used for paving or relatively flat high-temperature furnace parts. The inner liner tamped by the tamping tools has good compactness, high strength and good use effect.

Refractory castables, refractory spraying coatings and refractory tamping materials are different forms of unshaped refractory materials, and are also the refractory materials selected for lining a variety of industrial kilns. Because of their convenient construction, they are used in a variety of industrial kilns.

3.Ceramic fiber thermal insulation material is a kind of thermal insulation material, which is mostly used in industrial kilns that need thermal insulation to avoid heat loss. Ceramic fiber insulation materials include fiber blanket, fiber cotton, fiber felt, fiber board and other fiber materials.

According to different uses, different types of refractory materials are selected as the lining of high-temperature industrial kilns to protect the kiln shell from erosion, and play an important role in the normal operation of high-temperature kilns.
