7 Major Types of Refractory Materials Produced by the Leading Indian Refractory Companies

Refractory materials manufactured by the leading Indian refractory suppliers are generally referred to as different types of inorganic materials having a refractory capacity (degree) of 15800C or even above. These supplies include nature-made ores and a large number of other products manufactured to serve different purposes and requirements under extreme temperature conditions. As these products or materials have the capability of withstanding high temperatures due to certain mechanical properties, they are of immense significance in various industries.

 

This article sheds light on different types of refractory materials made and supplied by the leading Indian refractory companies on the following points:

 

1. Fired Refractory Materials 

 

Fired refractory materials are those products made and supplied by the leading Indian refractory companies that are achieved through the following methodologies:

 

  • Kneading
  • Molding
  • Drying
  • The high-temperature firing of granular
  • Powdery refractory raw materials, and
  • Binders. 

 

2. Non-fired Refractory Materials 

 

Non-fired refractory materials are those products for which perfectly suitable blinders, powdered refractory stuff, and granular are not fired and used directly. 

 

3. Special Refractory Materials

 

Special refractory products are a kind of materials that are believed to have some special mechanical properties concerning the capabilities of withstanding high temperatures. The refractories have a high melting point due to different types of oxides, carbon, and non-oxides components. 

 

4. Monolithic Refractory Materials 

 

Monolithic refractories are those materials made and supplied by the leading Indian refractory companies that are directly used in various refractory applications without any firing activities. They are used after grilling, mixing, or molding the materials. This is because the monolithic refractories come with a reasonable granular gradation. 

 

5. Functional Refractory Materials 

 

Functional refractory materials made and supplied by the leading Indian refractory suppliers are those materials that are mixed or blended with granulated as well as powdered refractories. These are also considered non-fired refractories comprehensively utilized to create a certain shape with a specific heating application. 

 

6. Fireclay Refractory Materials 

 

Fireclay refractories manufactured and supplied by the leading Indian refractory companies are hydrated aluminum silicates well-known for having 25% - 45% Al2O3 and 50% - 80% SiO2 and a large number of other minor minerals. Since fireclay refractory materials come cheaper and are available easily, they find applications in most furnaces, kilns, stoves, and regenerators, etc.

 

7. High Alumina Refractory Materials

 

The alumina refractories produced by the leading Indian refractory suppliers are those materials that contain more than 45% alumina. The alumina concentration in these refractory materials ranges from 45 to 95%. Some of the most commonly used refractories in this category include the following:

 

  • ·       Sillimanite (61%)
  • ·       Mullite (70 –85%), and
  • ·       Corundum (99%).

 

The applications of high alumina refractories include:

 

  • ·       Hearth and shaft of blast furnaces
  • ·       Lime and ceramic kilns
  • ·       Cement kilns
  • ·       Glass tanks, and
  • ·       Crucibles for melting a wide range of other metals.

 

Concluding Remarks 

 

RHI Magnesita is one of the leading Indian refractory companies. The company has the largest number of locations across the globe and offers the most innovative, reliable products and services. The company also provides the most robust supply and quality security due to its unmatched vertical integration – right from mining to the manufacturing of full-service solutions.
