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 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 Fire Brick

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.

Thick Wedge Fire Brick

T-19 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, T-9 refractory bricks are mainly used in furnace doors, arches, etc. in industrial kilns.

T-20Fire Brick

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.

Side Wedge Fire Brick

T-38 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, 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.

T-39 Fire Brick

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.
