Monolithic refractory, also popularly known as unshaped refractory, has a variety of sizes and shapes, making it a special type of refractory material. Monolithic castable refractory has a wide range of minerals in its content, which is quite different from other refractory material’s compositions. Thus, monolithic refractories have some prominent properties, such as low permeability, improved stability, better insulation and so on. These advantages are partly resulted from the manufacturing process of monolithic castable refractories. In this passage, detailed information about how to manufacture monolithic refractory cement will be provided.

How are monolithic refractories made?

Monolithic castable refractory is a rising refractory product benefited from Nanotechnology. The compositions of monolithic refractory cement can come in many different forms and recipes. Generally speaking, monolithic castable refractories mainly consists of alumina silicate and silicon carbide with graded cement and adhesives. They are usually made by some form of granular suspension and the mixture eventually harden into solid lumps. Most of the monolithic formulations consist of large refractory particles, fine fillers and binder phases. Monolithic refractories can be divided into plastic refractories, ramming mixtures, casting materials, gunning compounds, fettling mixtures, mortars and so on.

 

 

Types of monolithic refractories

Monolithic refractories can be manufactured in different recipes. Therefore, they could be divided into several types due to diverse methods, including plastic refractory, gunning compound refractory, ramming masses and so on.

 

 

Properties of monolithic refractories

Monolithic castable refractory has a variety of advantages, including its unique ability to vary sizes and shapes to adapt to different applications, its refractoriness, low thermal conductivity, low bulk density, high resistance to thermal shock and mechanical impacts, chemical inertness, low permeability and ability of energy saving. These prominent qualities ensure optimum performances of monolithic refractory cement in individual applications.

 

 

Applications of monolithic refractories

Monolithic castable refractories have a continuously increased demand in recent years. They are employed in a wide of range of fields due to their prominent characteristics, including metallurgical industry, mechanical industry, chemical industry, energy industry and construction industry.

 

Monolithic castable refractories can be used to build or repair different types of kilns. In this application, monolithic refractory cement has better performance than ordinary refractory bricks. The use of monolithic refractory can promote fast installation, prevent delays in producing special brick sizes, and often eliminate difficult brick laying work. They are of great significance in the application of kilns’ maintenance, because monolithic castable refractories are able to do substantial reparation work without wasting much time. They sometimes can even do fixing work during equipment’s operations.

 

As monolithic refractory cement is unshaped, it is usually used for filling gaps between joints in new construction to form joint free linings which would improve the overall performance of the product.

 

In summary, monolithic castable refractory is a new technological material. It has good characteristics and various applications in reality. In the future, monolithic refractory will have a broader range of uses.
