High strength alkali proof castable adopts low cement bonding technology, adding ultrafine powder and high efficiency dispersant. It has the advantages of high strength, good thermal stability, impact resistance, erosion resistance, wear resistance and long service life. High strength alkali proof castables excellent material selection, alkali resistant castable refractory up to 1790℃, excellent high temperature performance. The machine can be used for mixing, pouring construction, spraying type can be machine semi-dry spraying construction is convenient, greatly shorten the construction period, significant economic benefits.
High strength alkali proof castables is widely used, mainly used for lining of cement kiln preheater, lining of pipeline, lining of cooling machine, dressing of coal jet gun, front and rear kiln mouth, cooling machine and other high-temperature parts. Can be prefabricated into various sizes of prefabricated blocks, can also be used for spray construction (preheater lining).
This series of refractory castable is mixed with water to vibrate into mortar, or each type of prefabricated block can be made, spraying type can be applied by semi-dry spraying.
Due to the high flow rate of flue gas of circulating fluidized bed boiler, the erosion of coal ash particles and flue gas are serious, and the use environment of wear-resistant refractory materials for lining is bad, the operation practice has proved that the traditional refractory materials are not suitable for the operation of circulating fluidized bed boiler. In view of this situation, our company has developed a domestic advanced level of nanotechnology high strength alkali proof refractory materials.
As we all know, no matter what type of castable construction, it is necessary to check before construction, clean up the site and check whether the construction machinery and spare parts are in good condition. Before the construction of high strength alkali proof castables, preventive measures should be taken to prevent the metal such as firebrick from losing water. Whether the castable fails should be tested first. The quality of water must reach the prescribed standard. Before the construction, the site should prepare all the measures, to ensure that the construction can not break down, can not interrupt the construction.
