Refractories Important Aspects of every Industry

Refractory materials form the most important connection between the thermal process technology and the material to be heated. The functionality is related to the product quality as well as the cost of the heat processes. As we know that refractory materials goes through the best quality standards in critical application areas, such as metal, glass and ceramic production. The most important point of refractory is it must withstand very different thermal, chemical and mechanical loads. If the refractory withstand these loads it can produce large number of refractory products such as refractory and insulation bricks, dense shaped products such as basic, fireclay bricks or silica bricks, kiln furniture, fiber materials.

For industrial heat treatment, different types of furnaces are used. The selection of the furnace type depends on numerous parameters such as operating then required furnace atmosphere, maximum temperature, loading and support and transport of the material in the furnace. These are designed especially for each application such as usable volume, heaters, furnace lining and gas etc. Depending on the needs of the furnace user, furnace systems must be planned very flexibly for different products and production volumes or for constant high throughput of large-scale production.

It is true that the world cannot function without Refractories. Refractories are responsible for facilitating many modern manufacturing processes that rely on their robust properties.

The most important characteristic of a refractory is its ability to withstand high temperatures while maintaining dimensional stability after repeated thermal cycling.

Characteristics of Refractories are as follows

· Abrasion resistance

· Bulk density

· Cold crushing strength

· Creep

· Melting point

· Porosity

· Pyrometric cone equivalent

· Refractoriness under load
