  Metallurgical equipment operates under extreme duress—scorching temperatures, corrosive molten metals, and severe abrasion. Traditional materials like graphite and alumina often fail prematurely due to corrosion, sticking, or cracking. Boron nitride ceramics , however, offer a transformative alternative, combining chemical inertness, exceptional thermal stability (up to 2200 ° C), and inherent solid-state lubricity to solve the industry’s most persistent challenges. Here is the tradition application for Metallurgy.   1. Continuous Casting – Separator Rings and Side Dams One of the most critical applications is in continuous casting. In horizontal continuous casting, the separator ring connects the tundish to the mould and acts as the solidification starting point for molten steel, which must endure 1480–1560  ° C and severe thermal cycling. BN‑based composites (e.g., Si₃N₄‑BN) offer outstanding thermal shock resistance, corrosion resistance against steel, and complete non‑we...

In the processes of melting alloys, precision casting and high temperature metal processing, the nozzle is a key component that directly comes into contact with the molten metal, the material properties directly affect the melt flow stability, the purity of the alloy, and the long term reliable operation of the equipment. Regarding the problems that the traditional nozzle materials are prone to adhesion, reaction or have limited lifespan under high-temperature conditions, We have introduced boron nitride nozzles, providing a more stable and controllable solution for fusion welding applications.   Advantages of materials for use in molten metal environments   Boron nitride is a typical high performance functional ceramic material, featuring extremely high temperature resistance, excellent thermal shock resistance, and extremely low wetting properties towards most molten alloys. In the high temperature melting and metal transportation processes, boron nitride nozzles can effecti...

  1. Protective Materials During the steel smelting process, it can be used as a protective material to protect metal materials. For example, in the continuous casting process,  Boron Nitride (BN)  can be used as a protective slag to effectively prevent slag inclusion defects in castings and reduce the wear of the tundish and crystallizer. In addition, BN can also be used as a filter material for molten metal to filter out impurities and gases in the metal and improve its quality and purity.   2. Thermal materials Due to its high thermal conductivity and good thermal stability, this material can be used as a thermal material in the metallurgical industry.   For example, in the steel smelting process, BN can be used as the main material for high-temperature equipment such as crucibles and thermocouple sleeves and has good high-temperature oxidation resistance and high-temperature strength.   In addition, it can also be used as a lining material for high...

  Boron Nitride Nozzles for Molten Metal Atomizing Boron Nitride nozzles  are widely used in the processing of metal powder. Molten metal atomization is a process used to fabricate metal powder from a melt. In a typical atomizer, liquid metal is poured from a nozzle into a large chamber while being sprayed with high-pressure water, oil or gas. This causes the metal droplets to separate and condense into a powder that collects at the bottom. Atomization has become one of the most popular methods of powdering metals. Atomization begins in a furnace where the metal is kept liquefied by electric heating elements. The metal falls into the spray chamber through a “nozzle” – this nozzle is designed to a high degree of perfection and specification. The nozzle is one of the most important parts of the atomization process – a damaged or clogged nozzle can cause the metal flow to stop or the flow to increase dramatically – both of which can disrupt the powdering process. To prevent this ...
