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.

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.
The metallization of zirconia ceramic rod is to paste the ceramic rod on the inner wall of the metal with high-temperature resistant strong adhesive, and form a solid anti-wear layer after heating and curing. The production process of this product is relatively simple, the production cycle is short, and the cost is relatively low. Technical specifications: Mingrui Ceramics has various sizes of ceramic rods, which can also be customized according to customer needs. Metalized ceramic rods are basically not limited by size, with diameters ranging from 0.5mm to 160mm, and most of them can be produced.
Perforation of ceramic rod is to stick the ceramic rod with holes in the middle to the inner wall of the metal with high temperature resistant strong adhesive, and at the same time, the ceramic is firmly welded to the inner wall of the steel sleeve through the small holes through the spot welding process. To protect the solder joint, screw on the ceramic cap. Each porcelain rod is not only close to each other, but also forms a corresponding angle, so that the porcelain rods are closely connected without gaps; When the last piece of a circle is tightly embedded, a 360 ° mechanical self-locking force is formed between the porcelain blocks. The production process of this product is relatively complex, the production cycle is long, and the cost is high.
The integrally formed wear-resistant ceramic rod is assembled by pouring the ceramic rod into the steel sleeve with special filler after the ceramic rod is integrally fired. The ceramic rod has smooth inner wall, good sealing performance and good wear and corrosion resistance. However, the production cycle of this product is long and the cost is high.
The composite rod overcomes the characteristics of low hardness, poor wear resistance and poor toughness of the metal rod due to its high strength, good toughness, impact resistance, good welding performance and high hardness, high wear resistance, corrosion resistance and heat resistance of the corundum ceramic. Therefore, the composite rod has good wear resistance, heat resistance, corrosion resistance, mechanical shock resistance and thermal shock resistance, and good weldability.
Because zirconia ceramic rod has wear resistance, corrosion resistance and heat resistance, it can be widely used in electric power, metallurgy, mining, coal, chemical and other industries as a corrosive medium, and is an ideal wear-resistant ceramic rod.

Which refractory material is used for the construction of complex parts of kiln lining

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.
