What Is The Size Of Refractory Brick T20?

Refractory brick T20 is a refractory brick of a specific specification, where T20 represents the brick number of the refractory brick, also known as knife-shaped brick or small knife edge. Its size is 230*114*65/45 (mm). The shape of this brick is characterized by its thickness, which is wide at the upper end and narrow at the lower end. It is often used for the masonry of the arched part of the kiln.

The size of T20 refractory bricks is generally carefully designed so that when the kiln is built, it can meet the masonry of arched or circular parts, such as chimneys, craters, etc. The reason for designing such a size is that in addition to making the construction simple, it can also make the refractory bricks fit more closely, forming a solid structure, and effectively resisting high-temperature erosion and pressure. This is also the refractory brick model we commonly use in masonry arched parts.

At present, the materials of T20 refractory bricks mainly include high alumina, clay, corundum, etc. They can also be made into carbon-containing refractory bricks, zirconium-containing refractory bricks, and other different materials to meet the use requirements of different industrial kilns. In the selection process, we must choose different materials according to the actual kiln temperature, kiln medium, and other factors to ensure the stability of the kiln and the efficiency of production.

In addition to T20 refractory bricks, there are also T3 refractory bricks, T38 refractory bricks, T46 refractory bricks, etc. Their sizes are different, and there are hundreds of sizes of refractory bricks, so you should pay special attention when choosing.
