More Products >The density of refractory bricks refers to the weight of refractory bricks per unit volume, usually expressed in kilograms per cubic meter (kg/m³). Different types of refractory bricks have different densities, mainly depending on factors such as their composition and manufacturing process. The following are the density introductions of some common refractory bricks:
一. Density of several common refractory bricks
1. Density of aluminum silicate bricks: The density of aluminum silicate bricks is generally between 1.5-2.5 g/cm³.
2. Density of alumina bricks: The density of alumina bricks is relatively high, generally between 3.0-3.5 g/cm³.
3. Density of high alumina bricks: The density of high alumina bricks is also relatively high, generally between 2.6-2.9 g/cm³.
4. Density of silicon carbide bricks: The density of silicon carbide bricks is relatively high, generally between 2.8-3.0 g/cm³.
5. Density of magnesia bricks: The density of magnesia bricks is relatively small, generally between 2.0-2.5 g/cm³.
二. What does the density affect refractory bricks?
1. Compressive strength: Generally speaking, refractory bricks with higher density have greater compressive strength and can withstand greater pressure and load.
2. Wear resistance: refractory bricks with higher density have better wear resistance during use, and can better withstand friction and wear.
3. Thermal conductivity: The density of refractory bricks will also affect its thermal conductivity. Refractory bricks with higher density usually have lower thermal conductivity, which can play a certain role in thermal insulation.
4. Stability performance: refractory bricks with higher density usually have better stability performance, and are not easy to crack or damage under conditions such as long-term high temperature and repeated cold and heat cycles.
5. Cost: Refractory bricks with high density usually require longer firing time and more materials, so the cost is relatively high.
In summary, the density of refractory bricks has an important impact on its performance and application. In the actual selection, it is necessary to choose according to the specific use situation and requirements, and balance factors such as performance and cost to achieve the best use effect.
