Frequently Asked Questions

What are the advantages of silicon carbide graphite crucibles?

Silicon carbide graphite crucibles offer high temperature resistance, excellent thermal shock resistance, superior thermal conductivity, and long service life. They are ideal for melting non-ferrous metals, precious metals, and anode materials.

How should graphite crucibles be stored?

Graphite crucibles should be stored in a dry environment to avoid moisture. Wet crucibles may cause uneven heating and potential cracking during initial use.

What is the typical lifespan of a submerged entry nozzle?

Lifespan varies based on steel grade, casting speed, and operating conditions. Our high-quality nozzles typically last for multiple heats, with some applications exceeding 20 hours of continuous operation.

Do you offer custom refractory solutions?

Yes, we accept customized isostatic pressing of special-shaped refractory products. Our engineering team works closely with customers to develop solutions tailored to specific requirements.

What industries do you serve?

We serve the steel industry (continuous casting), non-ferrous metal smelting, precious metal refining, anode material production, gravity casting, die-casting, and other high-temperature industrial applications.
