In Mar. 50 tons high aluminum fire brick are packed for delivering to customer in Indonesia . High quality and nice price refractory materials product in Topower Refractory.
High alumina brick can withstand the temperature range of use, not easy to damage, melting. It also protects the furnace shell very well. The thickness of high aluminum brick also has great influence on furnace lining.
Although the thicker the high alumina brick is, the slower the heat source diffuses. But too thick is not scientific either. The reasonable thickness of high aluminum brick will prolong the service life of furnace lining. If it is used in the lining of rotary kiln with high aluminum brick, the thickness is generally between 220-250mm, because too thin thickness will reduce the service cycle, too thick will lead to small kiln diameter and low output. Not only increase the weight of the kiln. In addition, there will be extrusion of high aluminum brick phenomenon, affecting the normal operation.
If high aluminum bricks are used as permanent layers at the bottom of a calcium carbide furnace, generally six layers should be used for bricks with a thickness of 75mm. If it is used more, it will also affect the output of calcium carbide furnace. If the number of layers used in high alumina brick is reduced, it will also affect the service cycle. If the high aluminum brick is used in the furnace wall of calcium carbide furnace, the thickness is also reasonable at 345mm. If it is too thick, it will affect the output, and too thin will make the service cycle.
If high aluminum brick is used in hot blast furnace or blast furnace wall, it is also a reasonable thickness is the best choice. In the working layer, the thickness of the wall lining of hot blast furnace and blast furnace is generally 345mm, too thick is not good, too thin is not good.
If the high alumina brick is used in the waste incinerator, the thickness is about 230mm. If the thickness is 65mm, the service cycle will be quickly replaced due to wear resistance or erosion, delaying normal use, reasonable thickness is the best choice.
If it is some low temperature lining, below 1200℃ temperature, 114mm can also be used, 65mm thickness can also be used. It still depends on the temperature and erosibility of the furnace lining.
In short, no matter what type of furnace lining uses high aluminum brick, it depends on the actual use situation, can not be generalized. The reasonable thickness of high alumina brick will prolong the service life of furnace lining.
