Closed-Type Submerged Arc Furnace

Closed-Type Submerged Arc Furnace: Advanced Industrial Smelting Solution 

Shaanxi Heyuan's Closed-Type Submerged Arc Furnace represents cutting-edge metallurgical technology, delivering exceptional performance for ferroalloy production. Our industrial-grade burners have amazing specs: they can work at temperatures between 1800°C and 2200°C, have capacities between 10MVA and 125MVA, and recover more than 95% of the gas they burn. Our systems save 10-15% more energy than standard open designs. We've been making them well for over 20 years and have installed more than 400 furnaces around the world. The improved electrode adjustment system keeps the smelting process stable and the building is fully sealed to protect the environment.

What Makes Our Closed-Type Design Superior?

Your factory should have technology that makes it as efficient as possible while also being good for the earth. Our sealed furnace design keeps the reaction zone totally separate from the outside air. During mining, this arrangement collects all process gases, mostly carbon monoxide.

The tightly sealed cover completely stops the release of stray dust. You will like how this solves problems with environmental compliance while also recovering useful stove gas for making energy. The high-calorific gas (2000–2500 kcal/Nm³) cuts your net energy use per ton of material made by a large amount.

Key Technical Specifications

Industrial Applications and Versatility

Our ovens can be used by your building for a number of high-temperature tasks. Our closed system design makes it easier to melt ferroalloys on a large scale. When recovering energy is needed to make silicomanganese and ferrochrome, this technique works very well.

The sealed climate is very helpful for making calcium carbide. You'll be able to collect high-purity gas right away, which is necessary for making chemicals further down the line. The managed atmosphere keeps the reaction conditions stable and stops pollution.

Our Closed-Type Submerged Arc Furnace controls the microclimate and is perfect for activities that need to be done in harsh environments. Changes in the outside atmosphere won't affect your welding processes, so your electrodes will always work well and won't break.

Advanced Engineering Features

The furnace body utilizes full closed structure with harmful gas recovery exceeding 95%. This meets stringent environmental protection standards while improving your facility's sustainability profile.

Our high-efficiency electrode holders minimize contact resistance and reduce electrode consumption. You'll experience lower production costs through this optimized design. The intelligent electrode adjustment system automatically controls insertion depth, maintaining stable smelting conditions.

Premium furnace lining incorporates high-quality carbon bricks and refractory materials. These components resist high temperatures and corrosion for service life exceeding 2 years. Your maintenance schedules become more predictable and cost-effective.

Energy Efficiency and Cost Benefits

Energy consumption drops 10-15% compared to traditional open submerged arc furnaces. This improvement directly impacts your bottom line through reduced electricity costs. The thermal efficiency reaches approximately 80% versus 50-60% in open designs.

The sealed environment maintains controlled internal pressure, minimizing heat loss through radiation and convection. You'll appreciate how this stable environment prevents electrode oxidation typically seen in open furnaces.

Gas recovery systems capture valuable byproducts for power generation or heating applications. This closed-loop approach maximizes resource utilization while reducing waste.

Quality Control and Safety Standards

Our quality control focuses on sealing integrity, safety, and operational longevity. Rigorous pressure testing ensures no oxygen leakage that could cause safety concerns. The furnace hood and feed chutes undergo comprehensive inspection protocols.

Hydraulic and electrode systems receive precise calibration to prevent operational issues. Water-cooled components undergo hydrostatic testing at 1.5x operating pressure to detect potential weaknesses.

Automated safety interlocks monitor gas composition continuously. Online analyzers detect hydrogen, oxygen, and carbon monoxide levels, triggering protective measures when needed.

Rapid Delivery and Professional Service

Standard configurations ship within 15-20 days of order confirmation. Custom designs require 30-45 days, ensuring your specific requirements receive proper engineering attention.

Our operational team includes nearly 400 professionals with 11 senior experts providing rapid service response. You'll benefit from our 11+ years of metallurgical research and development experience.

Professional installation teams ensure proper commissioning and startup. We provide complete process solutions beyond just equipment delivery. Long-term wearing parts supply maintains your operations efficiently.

With our product, you're investing in proven technology that delivers consistent results while meeting environmental standards. The combination of energy efficiency, safety features, and reliable performance makes this the ideal choice for modern metallurgical operations.
