T38 Refractory Brick Size

T38 refractory brick is a common refractory brick size, which is often mentioned by people. It is also called knife-shaped brick or big knife brick. T38 represents the size of refractory brick, which is 230*114*65/55 (mm). This brick is thick on the top and thin on the bottom like T20 refractory brick. It looks like a knife from the side, so it is called a knife-shaped brick. It is often used for the masonry of the arched part of the kiln.

The reason why T38 refractory brick is designed to be thick on the top and thin on the bottom is mainly to meet the needs of arc-shaped kiln masonry. This can meet the diversity of kiln shapes. After masonry, the refractory bricks can be more closely laid, making the kiln more closed and effectively resisting high-temperature erosion and pressure. It is usually used in combination with T20 refractory bricks to make the masonry of arc-shaped or circular kiln parts more convenient.

At present, the materials of T38 refractory bricks mainly include high alumina, clay, magnesium, silicon carbide, corundum, and other materials. Reasonable selection should be made according to the actual situation of the kiln, such as the operating temperature of the kiln, the working medium of the kiln, etc., to ensure that the kiln is more stable and safe and ensure the actual use of the kiln.
