What are refractory products used for?

The purpose of a refractory material is to withstand the high temperatures required in furnaces, kilns, incinerators, power plants etc without contaminating other materials and to conserve heat in the area where it is needed.

What are examples of refractory materials?

The typical refractory materials include fireclay refractories, high alumina refractories, silica brick, Magnesite refractories, Chromite refractories, Zirconia refractories, Insulating materials and Monolithic refractory.

What is the refractory process?

Refractory manufacturing involves four processes: raw material processing, forming, firing, and final processing. Firing involves heating the refractory material to high temperatures in a periodic (batch) or continuous tunnel kiln to form the ceramic bond that gives the product its refractory properties.

Why refractory material is used in furnace?

Refractories are materials that are resistant to high temperature, used predominantly as furnace linings for elevated temperature materials processing and other applications in which thermomechanical properties are critical.

Are ceramics refractory?

Refractories are ceramic materials that are essential for all high-temperature industrial processes because they provide mechanical strength, protection against corrosion, and thermal insulation.

What is refractory give example?

Having a high melting point. Ceramics that are made from clay and minerals are often refractory, as are metal oxides and carbides. Refractory materials are often used as liners in furnaces. Resistant to heat.

What is ceramics and refractories?

Refractories are ceramic materials designed to withstand the very high temperatures (in excess of 1,000°F [538°C]) encountered in modern manufacturing. More heat-resistant than metals, they are used to line the hot surfaces found inside many industrial processes.

How is fire clay made?

Fire clay is a range of refractory clays used in the manufacture of ceramics, especially fire brick. The United States Environmental Protection Agency defines fire clay very generally as a “mineral aggregate composed of hydrous silicates of aluminium (Al2O3·2SiO2·2H2O) with or without free silica.”

What is boiler refractory?

Boiler refractory is heat-resistant materials that are used to line the boiler to help it retain heat. This prevents thermal loss during boiler operation. Refractory can be made of a number of different materials but is commonly brick, tile, castables or gunning mixes.

What is refractories and classification?

Refractories are classified according to their physical form. These are the shaped and unshaped refractories. The shaped is commonly known as refractory bricks and the unshaped as monolithic refractories. Shaped refractories are those which have fixed shapes when delivered to the user.
