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.

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-22) and two types of side wedge fire brick (T-38, T-41). Besides, we also support customized 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. 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 materials.
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 of T-19 refractory fire bricks is 230mm×113mm×55mm/65mm in length, width and height. Therefore, T-9 refractory bricks are mainly used 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. T-20 firebricks are mainly used for building arches in industrial kilns. T-20 is often used 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.
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, T-38 bricks are mostly used in general industrial boilers. T-38 bricks also are mainly used 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, T-39 refractory bricks are mainly used to build arches in industrial kilns. T-39 refractory fire bricks are often used in conjunction with T-3 and T-61 corner bricks when building arches.
Based on your specific requirements and application scenarios, Keruigroup can customize refractory bricks in various shapes as needed. Customized fire bricks can be designed in various special shapes according to specific application requirements. For example, corner firebricks and tapered firebricks. Specially shaped bricks are used to accommodate complex geometries, corners and transitions.
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.
