Introduction to Graphite Nozzle
A graphite nozzle is a precision refractory component processed from high-purity artificial graphite raw materials. With a unique tubular and conical structure, it is specially designed to control the flow rate, flow direction and flow stability of molten metal, high-temperature gas and liquid. Thanks to graphite’s excellent physical and chemical properties, graphite nozzles have become indispensable consumables in high-temperature industrial scenarios, widely recognized in metallurgy, casting, aerospace and laser processing industries.
Core Advantages of Our Graphite Nozzle
1. Extreme High Temperature Resistance
Graphite owns an ultra-high melting point of 3650℃. Our graphite nozzles maintain stable physical structure without melting or deformation under long-term ultra-high temperature working conditions. They perfectly adapt to severe high-temperature environments such as molten steel and molten aluminum casting.
2. Low Thermal Expansion & Thermal Shock Resistance
The product features an extremely low thermal expansion coefficient. It will not crack or damage under rapid temperature rise and fall, effectively resisting thermal shock damage and extending service life.
3. Excellent Corrosion & Oxidation Resistance
High-purity graphite material is chemically inert. It is insoluble in acid-base solutions and not wetted by molten metal. It can resist corrosion of various high-temperature melts and industrial chemicals.
4. Smooth Flow & Self-Lubrication
The dense and smooth inner wall provides natural lubricity, reducing fluid friction. It ensures uniform and stable flow of molten metal to avoid blockage and improve casting yield.
5. High Dimensional Precision & Customization
We adopt advanced CNC machining technology. All graphite nozzles have precise size tolerance, smooth cutting surface and customizable shapes including cylindrical, tapered and special-shaped nozzles.
Industrial Application of Graphite Nozzle
- Metallurgy & Metal Casting: Used for flow guiding of molten steel, molten copper and molten aluminum in continuous casting furnaces to control liquid metal flow steadily.
- Aerospace Industry: Applied to rocket engine tail nozzles to withstand ultra-high temperature combustion gas and ensure engine operation safety.
- Laser Welding & Cutting: Serve as auxiliary nozzles for high-power laser equipment to dissipate heat and improve processing stability.
- Chemical & Laboratory Industry: Suitable for high-temperature reaction vessels and gas spraying equipment for precise fluid control.
