What is the Requirement of Kiln for Fire Brick Function

With the development of industry, the application range and type of fire brick are more and more, refractory brick function is more and more obvious. Because the operating departments are different, even in different parts of the same furnace, the working conditions are not consistent. Accordingly, the requirement to fire brick also has different, so the function of fire brick generalizes several respects request in the following artcile.

1. Resist the effect of high temperature and heat load, and do not soften or melt.It is required that firebrick should have high fire resistance.
2. Resist the effect of high temperature thermal load, the volume is not shortened and only uniformly expands.It is required that the data have high volume stability, smaller residual shortening and larger residual expansion, no crystallinity change and severe bulk effect.
3. Resist the common effect of high temperature thermal load and heavy load, without loss of strength and creep and collapse.The data are required to be of moderate high ambient temperature strength and high temperature thermal strength, high load softening temperature and high creep resistance.
4. Resist sharp changes in temperature or uneven heating, without cracking or peeling.The data are required to have good thermal shock resistance.
5. Resist chemical corrosion of molten solution,dust and gas, and do not decay or corrode.Excellent slag resistance is required.
6. Resist the impact, impact and wear of fire, furnace materials and dust, and the appearance will not be worn.
7. The required data shall be properly dense and wear resistant at room temperature and high temperature.
8. Resist the influence of high-temperature vacuum operation and atmosphere change, and do not volatilize or damage.Data with low vapor pressure and high chemical stability are required

To ensure the overall quality of the masonry or lining of block firebrick. Slag resistance and air tightness are good, and it is convenient for construction. The data should be regular in shape and accurate in scale, so as to ensure certain service, and the root should never be allowed to exist defects. For some special requirements, sometimes it is necessary to consider its thermal conductivity and electrical conductivity. RS company produces all kinds of refractory bricks used in kilns, with different specifications, welcome to customize refractory bricks.
