HELLO ! look at here
2,Its thermal conductivity is the lowest among all refractory materials.
3,Although its refractoriness is as high as 1700°C, its softening temperature under load is only about 1400°C, making it resistant to rapid cooling and heating.
Next, let's talk about the data of the product.
| product name | clay bricks |
| AL2O3 content (%) | ≥50 |
| Compressive strength (MPa) | ≥40 |
| porosity | ≤28 |
| 0.2MPa load softening temperature (ºC) | ≥1400 |
| Line change rate after burning (%) | 2.5 |
Do you know the functional uses of refractory bricks?
A. Chemical composition: The main components determine the quality and characteristics of the refractory material
B. Volume density: unit volume weight. A high density means good density, which means the strength may be high, but the thermal conductivity may be high.
C. Load softening temperature: also called the temperature at which high-temperature loads begin to deform. This parameter is very important and marks the material's ability to withstand high temperatures.
D. Thermal shock resistance: the ability to resist sudden changes in temperature without being damaged
E. Compressive strength: the ability to withstand maximum pressure (at normal temperature)
F. Flexural strength: the ability to withstand shear pressure
G. Linear change rate: also called reheat line change or residual line change, refers to the change in volume expansion and contraction every time at the same temperature change. If the expansion and contraction are the same every time, we define such a linear change rate as 0
