The nozzle is a crucial component of the quenching and rapid solidification equipment. The fundamental production process is to melt the metal alloy, flow it out via a nozzle, and then employ high-pressure airflow at the outlet of the nozzle to atomize the molten metal and cool it into spherical particles simultaneously. The nozzle is embedded in the nozzle sleeve, and the molten alloy is ejected from the hole or slot of it. Due to the harsh working conditions of the nozzle used in the production of alloys, it must be able to withstand instantaneous thermal shock and high-velocity airflow impact, erosion of high-temperature molten metal, chemical corrosion, and oxidation. Therefore, the material used to manufacture the nozzle must possess a variety of superior properties.

A state-of-the-art option created for sectors requiring accuracy, robustness, and high-temperature performance is the Boron Nitride Nozzle. Meticulously designed to satisfy the most discriminating customers, our nozzles offer unmatched dependability and efficiency in advanced manufacturing, aerospace, and metal powder production.

The nozzle made of boron nitride offers great processing performance and excellent heat dissipation effect (good thermal conductivity). The addition of composite materials (such as alumina, zirconia, aluminium nitride, and silicon nitride) improves the toughness and thermal shock resistance, improves the material's deformation resistance, heightens the density, and enhances the erosion resistance of the nozzle. Moreover, the corrosion resistance of the material to high temperature metals is enhanced, which greatly contributes to the improved impact resistance and toughness of the nozzle, and reduces slag clogging on the nozzle body. The BN nozzle can be used in brazing amorphous alloys, as well as Fe-based, FeNi-based, Co-based, Ni-based, and Cu-based alloys.

High thermal stability, low friction coefficient, and remarkable resistance to chemical corrosion are only a few of the special qualities of boron nitride (BN), a synthetic ceramic material. It is supplied in powder, solid, and aerosol forms, each suited to particular industrial requirements.

Main Characteristics

Temperature Conductivity and Stability

High thermal conductivity of BN makes it perfect for high-temperature applications; it is stable at temperatures up to 3000°C in an inert atmosphere.

Excellent electrical insulator BN finds use in applications needing strong voltage resistance and thermal management.

Molecular Inertness

Durability under demanding conditions is ensured by its resistance to chemical attack, particularly from acids, alkalis and organic solvents.

Minimum Friction Coefficient

For uses requiring moving components and high wear, this characteristic makes BN a great material.

Second only to diamond in hardness, c-BN offers remarkable wear resistance.

Features of Boron Nitride Nozzles

Graphite, alumina, and silicon carbide are among the conventional materials that boron nitride nozzles outperform:

Extra Long Life

Longer operating lifespans from the combination of high hardness, thermal stability, and chemical resistance mean fewer replacements are required.

Enhanced Competence

Extreme conditions do not affect the structural integrity or performance of BN nozzles, which guarantees steady and dependable operation.

Savings on Maintenance

The longevity and corrosion and wear resistance translate into reduced maintenance expenses and downtime, which raises output levels all around.

Practicality

BN is a flexible option for many sectors because of their special qualities, which enable them usage in a broad range of applications.

Superior Thermal Control

Even with sharp temperature swings, our nozzles' minimal thermal expansion and great thermal shock resistance guarantee reliable performance. For operations where exact temperature control is critical, like gas atomization, this is essential.

Chemical Inertness and Resistance to Corrosion

Because boron nitride is naturally chemically inert, it is a great material to handle a variety of materials—including molten metals—without running the danger of contamination or deteriorating. Particularly important is this characteristic in sectors where product integrity and purity are non-negotiable.

Customization and Accuracy Machining

Our Boron Nitride Nozzles can be highly customized thanks to the use of cutting edge machining methods. Our production process can accommodate the particular dimensional needs and complex geometries of different applications.

Real-World Applications and Case Studies

Aerospace uses

BN nozzles are utilized in rocket propulsion systems in the aerospace sector to control the high temperatures and corrosive conditions that are present during launch while airborne. For example, BN nozzles in solid rocket motors function as ablative liners to shield the structural parts from the high-temperature exhaust gases. The propulsion system is kept safe and efficient by its capacity to withstand temperatures beyond 2000°C and to fend off chemical attack from the propellants.

Industry of Semiconductors

The semiconductor industry depends heavily on BN nozzles, especially for chemical vapor deposition (CVD) procedures that create coatings and thin layers. The exceptional purity and chemical inertness of BN avoid contamination of the semiconductor wafers, while their thermal conductivity provides uniform heating and cooling, resulting in high-quality, defect-free products. This application underlines the necessity of BN nozzles in maintaining the precision and dependability required in semiconductor fabrication.

Processing Metals

BN nozzles guide molten metal into molds during continuous casting of steel. Rapid heat dissipation made possible by BN's high thermal conductivity also helps to avoid the occurrence of flaws like fractures and guarantees a smooth, uninterrupted flow of the molten metal. The overall efficiency of the process is increased by the fact that BN nozzles' wear resistance lowers the likelihood of nozzle clogging, a typical problem in metal casting.
