What are the main characteristics of the use of refractory bricks

The effect of refractory bricks in our actual use is very great. In our use of refractory bricks, what are the characteristics of the use of refractory bricks? The editor will lead you to understand what characteristics should be possessed by the use of refractory bricks.

①It can resist the effect of high temperature heat load without softening and melting. The refractoriness of refractory bricks is required to be appropriately high.

②It can resist the effect of high temperature heat load, the volume is not shortened and there is only uniform expansion. The refractory bricks are required to have high volume stability, the residual shortening and residual expansion should be small, and there is no crystal change and serious volume effect.

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

④ It can resist the influence of rapid temperature changes or uneven heating, without cracking or falling off. Refractory bricks are required to have good thermal shock resistance

⑤ It can resist the chemical erosion of molten liquid, dust and gas, without deterioration and corrosion. Refractory bricks are required to have good slag resistance

⑥ It can resist the scouring, impact and wear of flame, charge and dust, and the surface is not lost. The refractory bricks are required to have appropriately high compactness and wear resistance at room temperature and high temperature.

⑦ Resist the influence of high temperature vacuum work and atmospheric changes, no evaporation, no damage. Refractory bricks are required to have low vapor pressure and high chemical stability. The shape is regular, the specifications and dimensions of the refractory bricks are accurate, high quality, low price, convenient Delivery, construction and maintenance, etc.

⑨ For refractory bricks with special requirements, their thermal conductivity, electrical conductivity and gas adaptability should also be considered.

Therefore, for refractory bricks, it is very important to have these characteristics, so that we can better use refractory bricks to meet our needs.
