Use Wedge Fire Brick in High Temperature Kilns

Ensure the Sealing Effect

This wedge-shaped brick has a trapezoidal shape at one end. When they are laid together, they form a perfectly fitting arc. Therefore, this brick can achieve a good sealing effect of the kiln. On this basis, you can then use enough high temperature mortar to fill the joints of the side arch and end arch bricks. More importantly, the thermal efficiency of the industrial furnace can be improved greatly. If you’re looking for a kind of refractory fire brick with superior sealing effect, the shape of wedge will be an ideal choice.

Save Masonry Costs

When encountering turning parts of the kiln, such as the top of the furnace, the corners of the furnace, etc., the use of wedge bricks can reduce the total amount of refractory bricks used. In addition, although it is cheap to buy standard-sized refractory firebricks, they need to be cut into specified shapes according to the working conditions when used, which consumes more labor costs. And the consumption of refractory mortar and other joint filling materials will be much less.
