High alumina castable fire clay bricks are used for certain projects. In order for bricks to be classified as ‘high alumina,’ they must be made using a certain amount of aluminum oxide. According to one source I’m taking a look at right now, the number is 90 percent. That makes these bricks a little different than other types of fire bricks. Are they more expensive, and do they have certain advantages over other fire bricks?
These bricks are supposed to offer the benefit of less grinding time. This can help to double productivity, which can of course be great for your operations. They are also supposed to provide for a longer service life, and you can count on less down time in general, too. Those are great benefits. Yet when it comes to less downtime, what types of bricks are these being compared to in order to come up with that finding?
In other words, are these high alumina refractory bricks going to have a longer service life than other fire bricks? What types of alumina bricks are there available for you to purchase or manufacture on your own? There are rectangle bricks, trapezoid bricks and other choices available. Those are based according to the shapes, but do the shapes have anything to do with the quality?
As you can imagine, each manufacturer is going to have different options available to consumers. You have to decide which bricks are best for your project. That will help you know whether or not you need these high alumina refractory bricks, or if you should be going with a different choice. Compare the benefits and advantages of various types of bricks. One manufacturer I say offers these high alumina bricks with a 92 percent aluminum oxide content.
You might want to check the specific aluminum oxide content levels that are stated by the brick manufacturers. Did you know that the industry standard today is the recognition that high alumina refractory bricks are known to be the strongest? That means they should last longer, right? You might want to consider going with these refractory bricks, but again, they aren’t your only choice.
High alumina refractory bricks have a different mechanical behavior than other similar insulated bricks. The materials that they are made of certainly make them the strongest bricks out there. If you are going to go with this type of brick based on quality, you are going to want to make a price comparison for sure. Is it going to be worth it paying a little extra for high alumina refractory bricks?
The natural sources for high alumina bricks are diaspora and bauxite. There are also unnatural sources as well. The more you learn about these bricks and how they work, the better you will be able to make a decision about using them for your projects. These bricks have a good reaction to thermal shock and acid slag. Read up more on these refractory bricks, and then you can make a purchase decision.
