Silicon nitride ceramic tapered nozzle
Alias: Wear-resistant ceramic tapered nozzle / tubes

Description：

Precision ceramic products such as silicon nitride ceramic nozzles and mechanical wear-resistant ceramic tapered nozzle / tubes play an important role in the industrial field. Due to their excellent wear resistance, high temperature resistance, chemical stability, etc., they have been widely used in spraying, grinding, cutting, metallurgy and other fields. Among them, silicon nitride ceramic tapered nozzle is the core component of the waterjet cutting system.

Features:

1. Abrasion resistance
Silicon nitride ceramic nozzles, mechanical wear-resistant ceramic tapered nozzles/tubes and other products, have excellent wear resistance and can maintain a stable surface state under the impact of high-speed liquid flow or particle flow, and are suitable for spraying, grinding, cutting, liquid conveying and other processes.
The silicon nitride ceramic tapered nozzle, which not only withstands the friction of abrasives well, but also copes with the ultra-high pressure of the jet (> 4000 bar), it can last 300% or more compared to steel.

2. Hydrodynamic design
The cone angle of the tapered structure is usually 12°–15°, and the internal hole accuracy ± 0.02mm, preventing jet divergence. This structure can increase the water flow velocity from subsonic speed (300 m/s) to supersonic speed (≥600 m/s), and the abrasive acceleration is completed simultaneously.

3. High temperature resistance
These precision ceramic products have excellent high-temperature resistance and are not easy to deform or break in high-temperature environments, making them suitable for high-temperature furnaces, heat treatment equipment and other application scenarios.

4. Chemical stability
Silicon nitride ceramic nozzles, mechanical wear-resistant ceramic tapered nozzles/tubes and other products, have excellent chemical stability, can resist chemical corrosion such as acid-alkali solutions and corrosive media, and maintain long-term stable performance.

5. Precision machining
These precision ceramic products can be customized for precision processing to meet customers' specific size, shape, surface finish, and other requirements, ensuring the accuracy and reliability of the equipment, such as the flow control accuracy of nozzles, the inner diameter and dimensional accuracy of tapered nozzles/tubes.

Applications:

1. Spraying process
In the spraying process, silicon nitride ceramic nozzles are widely used in spraying equipment, which can generate a stable spray flow, achieve precise coating spraying, and improve coating efficiency and coating quality.

2. Grinding processing
In grinding processing, products such as mechanical wear-resistant ceramic tapered bushings are used as key components of grinding wheel grinding equipment, which can withstand high-speed rotation and high-pressure working conditions and extend the service life of grinding tools.

3. Ultra-high pressure hydraulic cutting field
Silicon nitride ceramic tapered nozzle is the core component of the waterjet cutting system. The solid-liquid mixture (emery including garnet/alumina, etc. - a mixture formed with an ultra-high-pressure water stream) inside this nozzle will create a powerful abrasive jet (sand-water jet) at the nozzle, followed by a waterjet cutting of the material.

4. Metallurgical industry
In the metallurgical industry, these precision ceramic products are used in key components of high-temperature melting equipment, such as the nozzle of the blowing furnace, the tapered casing of the melting furnace, etc., which can withstand the working environment of high temperature and high pressure, ensuring the stable progress of the smelting process.

5. Chemical field

In the field of chemicals, silicon nitride ceramic nozzles, mechanical wear-resistant ceramic tapered casings and other products are used in the conveying and spraying equipment of corrosive media, such as: chemical pipeline spraying systems, chemical reactor nozzles, etc.
