Which refractory material is used in the construction of complex parts of kiln lining
The construction of the complex parts of the high temperature kiln equipment can be selected according to the actual situation. If the mold cannot be supported, refractory smears, wear-resistant plastics, etc. can be used. If it cannot be vibrated, wear-resistant self-flowing castables can be used.

Compared to other monolithic refractories, the main differences in coatings are particle ratio, trace additions, deletions and water additions. The amount of water added to the refractory coating can be changed after changing its application method. If spray application increases the amount of water, reduce the amount of water for tamping application.
The properties of refractory spreads depend on the ratio of refractory aggregate to powder, as well as the type of binder. The coating has a certain plasticity, mud, hand coating or mechanical spraying charm, usually requires high strength, good melt or gas corrosion resistance, good coating adhesion, good thermal shock stability, good chemical stability, no cracking , no peeling, etc.
Self-flowing refractory castables have been paid more and more attention due to their excellent construction properties and physical and chemical properties. Self-flow series products are suitable for construction site chaos, used in cement industry, metallurgical industry, non-ferrous metallurgy industry, such as tundish intermediate layer, blast furnace bottom, secondary movement CAS-OB movable cover lining, cast iron tank induction insulation layer, heating furnace, full Hot furnace, rotary kiln cooler, burner, ammonia gasifier, carbon black reactor, civil waste incinerator lining, etc. It can also be used to repair the kiln lining data and prolong the service life.
