RH Furnace
RH Furnace: Advanced Vacuum Degassing Solution for Steel Refining
Shaanxi Heyuan's enterprise-grade RH Furnace delivers exceptional vacuum degassing capabilities for large steel complexes, featuring ultimate vacuum levels ≤67Pa and treatment capacities from 60t to 300t. Operating at temperatures between 1550°C-1650°C, our advanced system reduces hydrogen content to ≤2ppm while maintaining composition deviation ≤±0.03%. With over 400 delivered units worldwide and 20+ years of metallurgical expertise, Shaanxi Heyuan provides comprehensive solutions from design to commissioning, ensuring your steel refining operations achieve superior quality and efficiency.
How RH Furnace Technology Works?
Our vacuum recirculation degassing system uses a unique dual-snorkel design. The up-leg and down-leg snorkels create an argon lift pump effect. This forces molten steel into the vacuum chamber where it disperses into droplets.
During this process, dissolved gases are released efficiently. The treated steel then circulates back through the down-leg. This continuous circulation ensures uniform composition and temperature throughout your molten steel.
Key Applications and Industries
Automotive Steel Production
You can produce ultra-low carbon steel for car body panels. Our system achieves carbon levels below 20 ppm. This meets the demanding requirements for deep-drawing properties without fracturing.
Pipeline Steel Manufacturing
When you need high-performance line pipe steels, our RH Furnace removes hydrogen to prevent cracking. This is crucial for sour service applications in corrosive environments.
Electrical Steel Processing
For transformer and motor applications, you get precise silicon and aluminum alloying. We maintain ultra-low carbon and sulfur levels to minimize magnetic losses.

FAQ
Q: How does your system handle temperature loss during treatment?
A: We incorporate chemical heating systems and top lance burners to compensate for temperature drops. This maintains optimal processing conditions.
Q: What maintenance is required for the snorkels?
A: Snorkels typically last 60-150 heats depending on refractory quality. We provide interchangeable cassettes to minimize downtime.
Q: Can the system perform desulfurization?
A: Yes, by adding appropriate fluxes during treatment. However, we recommend our LF furnace systems for deep desulfurization requirements.
