Fire brick plays a vital role in high-temperature applications, providing insulation and structural support in various industries. The sizes and shapes of refractory bricks are carefully designed to meet specific requirements and optimize performance. Therefore, in this article, we will explore the common sizes and shapes of fire brick and its applications.

Classification of Fire Brick Sizes and Shapes
There are usually 6 types of high temp refractory bricks. That is two types of straight fire brick (T-3, T-6), two types of thick wedge fire brick (T-19, T-20) and two types of side wedge fire brick (T-38, T-39). Besides, we also support customized fire brick.
Straight Fire Brick
T-3 refractory brick is a standard brick type. Its shape and size are fixed, but its material is not. Among straight refractory bricks, T-3 brick is the most widely used type of refractory brick and is used in almost every kiln. Moreover, the volume of T-3 refractory bricks is approximately 1704cm³. Besides, the dimensions of T-3 refractory bricks are 230mm×114mm×65mm in length, width and height.
T-6 refractory bricks are not as widely used as T-3 refractory bricks. In addition, the volume of T-6 firebricks is about 2000cm³. The length, width and height of T-6 refractory bricks are 250mm×123mm×65mm. What’s more, T-6 refractory firebricks can be divided into clay bricks, semi-silica bricks, high alumina bricks, silica bricks and lightweight clay bricks according to their different refractory materials.
Sizes and Shapes of Thick Wedge Fire Brick
Among thick wedge refractory bricks, T-19 is the most widely used brick type. Its shape is wide at one end and narrow at the other. Generally speaking, its volume density is 1443 cm³. Furthermore, the size and shape of T-19 refractory fire bricks is 230mm×113mm×55mm/65mm in length, width and height. Therefore, we mainly use T-9 refractory bricks in furnace doors, arches, etc. in industrial kilns.
The volume of T-20 refractory bricks is approximately 1704cm³. The length, width and height of T-20 high temperature fire bricks are 230mm×114mm×65mm/45mm. We mainly use T-20 firebricks for building arches in industrial kilns. We often use T-20 in conjunction with T3 and T-54 corner bricks when building arches. The advantages of using T-20 bricks for masonry are the same as T-19 bricks.
Side Wedge Fire Brick
T-38 refractory bricks are wide and long. The volume of T-38 refractory bricks is approximately 1704cm³. The size specifications of T-38 refractory bricks are 230mm×114mm×65mm in length, width and height. Generally, we mostly use T-38 bricks in general industrial boilers. We mainly use T-38 bricks also for building arches, furnace doors, etc. in industrial kilns.
The volume of T-39 firebricks is approximately 1443cm³. The dimensions of T-3 refractory bricks are length, width and height 230mm×114mm×45mm/65mm. In addition, we mainly use T-39 refractory bricks to build arches in industrial kilns. We often use T-39 refractory fire bricks in conjunction with T-3 and T-61 corner bricks when building arches.
Customized Fire Brick
Based on your specific requirements and application scenarios, Keruigroup can customize refractory bricks in various shapes as needed. We design customized fire bricks in various special shapes according to specific application requirements. For example, corner firebricks and tapered firebricks. We use specially shaped bricks to accommodate complex geometries, corners and transitions.
Conclusion
By understanding the various sizes and shapes of fire bricks available, you can choose the most suitable refractory brick. Meanwhile, this optimizes the performance and durability of the refractory bricks in high-temperature operations.
