AI Technical Summary

Problems solved by technology

If the baking temperature is lower than 450°C, the phosphate bonded refractory may be damaged due to the failure of the aluminum orthophosphate bond phase
If the service temperature is higher than 1000°C, the phosphate bonded refractory may lose wear resistance due to the softening of the aluminum phosphate / calcium phosphate bond phase
[0004] On the other hand, when low cement is used as the binder, the low cement bonded paint has poor bonding and slow hardening.
Low-cement bonded smear not only needs more than 24 hours of curing to harden, but also has poor adhesion, so it is difficult to apply to the side wall and cannot be used to smear the top wall

Abstract

The invention belongs to the technical field of fireproof materials, in particular relating to an unshaped fireproof material with good daubing performance, hardenability, intensity and wear resistance. The rapid-hardening wear-resisting unshaped fireproof material has the advantages of good workability, rapid hardening speed, and high wear resistance, and can satisfy the requirements on rapid construction, emergent maintenance, wear resistance and erosion resistance of high-temperature furnaces.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to an unshaped refractory material with good smearability, hardening performance, strength performance and wear resistance. Background technique [0002] In the prior art, the smeared refractories used in high-temperature kilns generally use phosphate or low cement as the binder. However, in the actual application process, the above-mentioned binders have various shortcomings and cannot fully meet the construction requirements. [0003] On the one hand, when phosphate is used as the binder, the phosphate-bonded spread has good bonding performance, but the construction and use performance are not satisfactory. Phosphate bonded paint can be used to coat the furnace side walls as well as the ceiling. However, phosphate-bonded monolithic refractories use cement as a hardening agent, which not only requires more than 16 hours of curing to harden, but also needs to be baked...
