Benefits of Using Corundum Bricks in Your Kiln

Long Service Life

Corundum bricks are strong in both compressive strength and chemical resistance. This also means that this product can still maintain good and stable characteristics in the face of harsh working environments, so it can keep the kiln running stably at high temperatures.

Low Energy Consumption

One of the most important properties of corundum bricks is strong thermal conductivity. Therefore, in the corundum refractory lining, heat will be transferred quickly and evenly. This also means that you can save some fuel.

Wide Uses

In fact, Kerui Refractory recommends customers to use corundum bricks in kilns with higher working conditions. Because its performance is excellent in all aspects. Of course, this brick has a particularly wide range of applications and can play a good role.
