The construction of complex parts of high-temperature kiln equipment can be selected according to the actual situation. If it is impossible to support the mold, fire-resistant coating materials, wear-resistant plastic materials, etc. can be used. If it is impossible to vibrate, wear-resistant self-flow castables can be used.

Compared with other amorphous refractories, the main differences of coating are particle ratio, micro addition, deletion and water addition. The amount of water added to the refractory coating can change its construction method after changing. If the spraying construction increases the water volume, the tamping construction will be reduced.
The nature of refractory coating depends on the proportion of refractory aggregate and powder and the type of adhesive. The coating has certain plasticity, slurry, manual coating or mechanical spraying charm, and generally requires high strength, good resistance to melt or gas corrosion, good coating adhesion, good thermal shock stability, good chemical stability, no cracking, no peeling, etc.
Self-flowing refractory pouring materials have attracted more and more attention due to their excellent construction performance and physical and chemical properties. The artesian series products are applicable to the chaos of the construction site and are widely used in the cement industry, metallurgical industry and non-ferrous metallurgical industry, such as the tundish intermediate layer, the bottom of the blast furnace, the secondary movement CAS-OB movable cover lining, the induction insulation layer of the cast iron tank, the heating furnace, the full-heat furnace, the rotary kiln cooler, the burner, the ammonia gasification furnace, the carbon black reaction furnace, the civil waste incineration furnace lining, etc. It can also be used to repair kiln lining data and prolong service life.

What are the characteristics of alumina ceramic tubes?
Zirconia ceramic rod is processed by isostatic pressing process to form uniform, dense and smooth ceramic layer and transition layer under high temperature and high speed. Because the manufacturing process is advanced and the cost is high, it is suitable for precision ceramic parts, and its wear resistance is stronger than other ceramic rods, so it is generally used as a place with high wear resistance.

Comparison of advantages of zirconia ceramic and alumina ceramic materials
The toughness of zirconia ceramics is four times that of alumina ceramics. At the same time, zirconia will fall freely from a height of one meter, but there will be some gaps. The alumina will break.
