Several Different Types of “T” Refractory Bricks
T19 refractory bricks also called ax bricks. The size of the T19 mullite brick is 230×114×65/55mm. The country stipulates the size of bricks in order to facilitate calculation and save resources. There are many types of refractory bricks, and their shapes and sizes are quite complicated, but they all stipulate a unified brick number. People with rich experience and knowledge of refractory bricks can know its purpose, even shape, size, and weight from the brick number. For example, bricks with the prefix “T” are commonly used in general industrial furnaces. From “T-1” to “T-105”, there are more than 20 shapes and 105 brick numbers (specifications). Another example is the bricks with the prefix “G” are used for blast furnaces. There are two shapes and 8 specifications from “G-1” to “G-8”. The size of the T19 refractory bricks produced and processed by Zhengzhou Rongsheng Refractories is strictly implemented in accordance with the standard size, and customers are welcome to come and inspect. Next, let’s learn more about the “T” refractory bricks.
Several Different Types of “T” Refractory Bricks
The cylindrical lining uses T3 bricks to match T38 bricks and T39 bricks (thicker lining). Or use T3 bricks with T19 bricks and T20 bricks (thin lining) for masonry. When designing, we must go through strict calculations to ensure that the “T” refractory bricks joints are basically the same.
- T3 is a standard brick with dimensions (length×width×height): 230×114×65.
- T38 and T39 are wedge-shaped bricks, also called knife-shaped bricks, with dimensions (length×width×height) respectively: 230×114×65/55 and 230×114×65/45.
- T19 and T20 are called ax-shaped bricks, and the dimensions (length×width×height) are 230×114×65/55 and 230×114×65/45, respectively.
- The thickness of T38 and T39 is gradually reduced from 65 to 55/45 in the length (230) direction.
- The thickness of T19 and T20 is gradually reduced from 65 to 55/45 in the width (230) direction.
T19 Mullite Bricks
T19 mullite bricks are mainly used in metallurgical hot blast furnaces with high blast temperature above 1400℃. The parts and slag lines of the torpedo car hit by molten iron. The roof of the steel-making electric arc furnace, the forehearth of the glass melting furnace, the regenerator arch, and the upper structure. Ceramic sintering kiln, ceramic roller kiln, tunnel kiln, electric porcelain drawer kiln, dead corner lining of petroleum cracking system, glass crucible kiln, and various electric furnaces, etc. The wall of the clarifier, cement and lime rotary kiln lining, etc. They can be directly contacted with flame.
Mullite bricks are aluminum-silicon refractory products with mullite as the main crystal phase. Because the main crystal phase of mullite brick is mullite. Therefore, the properties of mullite bricks are as follows: the high-temperature resistance of mullite bricks can reach above 1790℃, the starting temperature of load softening is 1600-1700℃, and the compressive strength at room temperature is 70-260MPa. Good thermal shock resistance, high strength, low high temperature creep rate, low expansion coefficient, low thermal coefficient, and acid slag erosion resistance. It can also greatly reduce the weight of the high-temperature furnace body, transform the structure, save materials, save energy, and improve production efficiency.
Rongsheng Refractory Bricks Manufacturer
The mullite bricks produced by Zhengzhou Rongsheng Refractory Bricks Manufacturer are mainly divided into lightweight mullite bricks and corundum mullite bricks. Lightweight mullite bricks use imported tabular corundum and high-purity fused corundum as the main raw materials. It is made by applying advanced superfine powder adding technology, mixing, drying, forming, and firing in a high-temperature shuttle kiln. Corundum and mullite refractory bricks are made of dense fused corundum and alumina powder as the main raw materials, which are mechanically mixed and high-pressure forming and high-temperature firing. Through the purity of the corundum sand and the process formula to meet the requirements of different corundum products using temperature.
