The constantly growing demand particularly from steel and foundry industry hasn’t allowed the pace of development to be compromised.  The following section briefly elaborates on the merits and applications of Refractory Castables. <br /><br /><strong>Advantages Of Refractory Castables:</strong><br /> <ul> <li><strong> Shrinkage: </strong>Typical problems like warping or burning cannot be associated with Refractory Castables even at extremely high temperatures. As the chemical reaction starts, the powder starts creating ceramic bonds subsequently.</li> <li><strong>Green strength: </strong>with strength similar to conventional concrete refractory castables can be driven easily even before getting fired.</li> <li><strong>Fire strength and toughness: </strong>Refractory castables are harder than conventional concrete. Due to its ability to collect and arrest crack propagation it is tougher than ceramics. High Alumina Refractory Castables are known for its strength.</li> <li><strong>Drying Time: </strong>refractory castables take less time to dry and dismiss water from its surface. High Alumina Refractory Castables are used as a binder, also they take very short time for setting that conventional cement.</li> <li><strong>Thermal shock: </strong>Refractory castables are highly adaptable to temperature changes. They are designed and manufactured such that they handle rapid changes and fast firing.</li> </ul> <br /><strong>Applications Of Refractory Castables:</strong><br /> <ul> <li>Castables are used to make burner blocks to withstand the decreasing outcome of oil firing and localizing over heating caused by carbon build up.</li> <li>Used in the lining of sidewalls to get more support by using ceramic anchors. This gives more adequate lining than brick line up.</li> <li>They are used in steel industries and glass industries.</li> <li>Castables are used to make furnaces. They increase the rate of intermediate repairs and decrease number of joints to reduce heat loss.</li> </ul> <br />Due to their evident advantages <b><a href="http://www.firebricks.in/refractory-castables.htm">Refractory Castables</a></b> are high on demand. They show exceptional performance with their physical, mechanical and thermal properties, and are used in large number of industries. Features to look for in Insulating Bricks http://www.firebricks.in/blog/features-to-look-for-in-insulating-bricks_5333.htm Fri, 05 Jun 2015 11:05:15 +0530 <p>It happens very often that people looking for refractory material get confused between Insulating Bricks and Dense Firebricks. While both of them have refractory properties and are able to sustain extremely high temperatures, the feature that differentiates the two is that Insulation Bricks do not absorb heat whereas Firebricks do. The other difference is that the former ones are lighter and the latter ones are heavy. For applications where thermal insulation is needed, Insulating Bricks are to be used. Made with aluminum and silica, these bricks are typically used as a back-up lining in kilns and furnaces and also as a primary hot face refractory lining. <br /><br />If you are buying them from an <strong><a href="http://www.firebricks.in/insulating-bricks.htm">Insulating Bricks Supplier in Gujarat India</a></strong> for the first time, know about the features you should look for.</p> <p> </p> <ul> <li><strong>Insulating Value: </strong>Depending on your application’s requirements you should check the insulation ratings of the bricks. The formula of ‘higher the insulation value, higher the price’ is applicable most of the times, so do not go for exceedingly high ratings than what is actually required. Needless to say, going below that value is not even an option. </li> <li><strong>Purity Levels: </strong>Iron and alkali flux content are some of the commonly found impurities which affect the performance of bricks. Unless you get a sample of bricks and test them, there is no way to know about it but trust the word of your Insulating Bricks Manufacturer. Buy from them only when you have established a reasonable level of trust. </li> <li><strong>Dimensional Accuracy:</strong> This is one of the crucial factors to consider as it directly affects the performance of bricks. This might sound absurd as how can precise measurements affect quality? But think, when you are getting them installed and due to the inaccuracies, gaps are being left between bricks. This would mean heat loss through those gaps. Some Insulating Bricks Manufacturers in Ahmedabad offer them in customized shapes as well to suit your specific requirements. </li> </ul> <ul> <li><strong>Low Heat Storage:</strong> If Insulation Bricks start absorbing heat instead of offering protection against them, the purpose of their installation would be completely defeated. Thermal conductivity of bricks should be as low as possible. </li> </ul> <p> </p> <p>With kilns, furnaces and other such heated work areas, the operating temperatures are exceedingly high. Thusly, installing reliable material for such operations is of immense importance. So be sure of the quality before you ask for quotes from different suppliers.</p>
