A Complete List Of Special-Shaped Refractory Bricks

In the process of building kilns in the high-temperature industrial field, to meet the needs of various complex industrial kiln lining structures, special-shaped refractory bricks are very important. They can be selected according to the specific shape of the kiln lining, and are often used in the masonry of some special-shaped kilns such as round and arched ones.

Common special-shaped refractory bricks

1. Arch foot bricks

Arch foot bricks are a kind of trapezoidal refractory bricks, mainly used in the corners of the vaults of industrial furnaces, bearing high temperatures and structural stresses. They are widely used in the blast furnace vaults of steel plants to ensure the stability and sealing of the furnace roof structure.

2. Knife-shaped bricks

Knife-shaped bricks are a kind of refractory bricks with a wide top and narrow bottom. They are shaped like a kitchen knife, so they are called knife-shaped bricks. They are mostly used in special-shaped furnace doors, observation holes, and other parts. Around the furnace door of the heat treatment furnace, knife-shaped bricks can effectively prevent heat leakage.

3. Anchor bricks

Anchor bricks usually have anchor claws or holes, which can be firmly connected to the furnace shell or steel structure. They are mostly used to fix the refractory lining to prevent it from falling off at high temperatures.

4. Wedge bricks

Wedge bricks are refractory bricks with one end thick and the other end thin. They can be adjusted at different angles during masonry through different combinations and can be used to adjust the masonry arc and angle of the furnace lining.

5. Fan bricks

Fan bricks are a type of brick with a fan-shaped body that can be tightly spliced to form a smooth curved surface. They are usually used for the masonry of circular or curved furnace walls. In the furnace wall of a glass melting furnace, the use of fan bricks can effectively reduce heat loss and improve the thermal efficiency of the furnace.

6. Tongue bricks

The shape of the tongue brick is similar to a tongue, which can smoothly transition and reduce stress concentration. It is mainly used in the transition between the furnace bottom and the furnace wall.

7. Dovetail bricks

The unique dovetail shape of dovetail bricks can provide a good self-locking effect. It is suitable for structural parts that need to be interlocked to enhance overall stability. In the lining of a cement rotary kiln, the use of dovetail bricks can prevent the bricks from falling off at high temperatures.

In addition to the above common special-shaped refractory bricks, some special-shaped refractory bricks can be customized according to actual needs. There are many types. Generally, when choosing, we should choose according to the design requirements and actual working environment of industrial kilns to ensure the safe and efficient operation of the kiln, improve production efficiency, and reduce maintenance costs.
