What are the requirements for the use of high alumina bricks?

There are certain requirements for high alumina bricks in the process of use. Now I will share with you what are the requirements for their use?

1. It can resist the shaking of high temperature heat load, without softening and melting. The fire resistance of refractory bricks is required to be quite high.

2. It can resist the effect of high temperature heat load, the volume does not shrink, but only expands uniformly. Refractory bricks require high volume stability, small residual shrinkage and residual expansion suits, no crystal changes and serious volume effects.

3. It can resist the combined action of high temperature thermal load and heavy load, without losing strength, without creep and collapse. Refractory bricks are required to have relatively high normal temperature strength and high temperature thermal strength, high load softening temperature, and high creep resistance.

4. It can resist the shadow of rapid temperature change and uneven heating, no cracking or peeling. Refractory bricks are required to have good thermal vibration resistance.

5. Resistant to chemical attack by solution, dust and gas, without deterioration or corrosion. Refractory bricks are required to have good slag resistance

6. It can resist the erosion, impact and wear of flame, furnace material and dust, and the surface will not be lost. Refractory bricks are required to have fairly high compactness and wear resistance at room temperature and high temperature.

7. Resist the shadow of high temperature vacuum operation and atmospheric changes, non-volatile and non-damaged. Refractory bricks are required to have lower steam pressure and higher chemical stability. The shape is neat, the specifications and dimensions of the refractory bricks are accurate, the quality is good, and the transportation, construction and maintenance are convenient.

8. For refractory bricks with special requirements, their thermal conductivity, electrical conductivity and air permeability should also be considered.
