Polysilicon Melting Furnace
Polysilicon Melting Furnace - Advanced Silicon Processing Solutions
The Polysilicon Melting Furnace at Shaanxi Heyuan is a large machine used to make electronics and photovoltaics. Our state-of-the-art guided solidification systems can handle loads of 150 kg to 1000 kg at temperatures of up to 1400°C to 1500°C, and they can be controlled with a precision of ±1°C. Ozone levels below 5ppm are kept safe by inert gas safety systems in these furnaces. They can make up to 99.9999999% pure polysilicon, which is good enough for electronics. Our options are good for high-volume production because they can handle power levels between 50kW and 300kW and can be made to fit your needs. Smart process tracking and automated thermal field management tools help them keep the standard good.

Core Applications
Photovoltaic Industry
For your industrial needs, you need silicon ingots that are always of high quality. Our melting ovens turn raw polysilicon into multicrystalline ingots that are great for making solar wafers. Precise thermal control makes sure that the grain structure is regular, which increases the rate of photoelectric conversion in the solar cells you make.
Semiconductor Manufacturing
Our ovens provide electronic-grade purity levels for silicon that you need to be very pure for electrical uses. The modern vacuum protection system gets rid of the chance of contamination, making sure that your semiconductor substrates meet the highest standards in the business.
Silicon Recycling Operations
Turn waste sources of silicon into useful fuel. Our Polysilicon Melting Furnace systems can be used at your plant to handle pot scrap, off-spec wafers, and production leftovers. Silicon's natural segregation properties will clean up the recycled materials.
Advanced Features & Benefits
Precision Temperature Management
The uniformity of your production relies on how stable the temperature is. Our heaters keep the temperature in the melt zone within ±1°C of being the same everywhere else. This level of accuracy stops heat stress and makes sure that the crystallization patterns stay the same as you make more ingots.
Contamination Prevention
Protecting the clarity of silicon is very important for the quality of your product. The built-in inert gas safety system keeps oxygen levels below 5ppm, which stops oxidation and metal pollution while the melting process is going on. The end goods you make meet the purity standards needed by today's tech markets.
Directional Solidification Technology
Advanced cooling devices let you control how your crystal structure forms. The carefully controlled thermal gradient pushes impurities to specific places, which increases the amount of useful silicon and makes it work better electrically.
Intelligent Automation
Comprehensive process control will help you run your business more smoothly. The built-in tracking systems keep an eye on every step of the melting and solidification process. This makes sure that the results can be repeated and that the quality of the production is always high.
Technical Advantages
Enhanced Energy Efficiency
Your operational costs benefit from optimized thermal design. The advanced insulation systems and heating configurations minimize energy consumption while maintaining the high temperatures required for quality product operations.
Flexible Capacity Options
Scale your production according to market demands. Whether you're running pilot-scale batches or full industrial volumes, our customizable capacity range accommodates your specific throughput requirements without compromising quality standards.
Safety Systems Integration
Protect your investment and personnel with comprehensive safety features. Emergency cooling systems, leak detection sensors, and pressure relief mechanisms ensure safe operation even during unexpected process conditions.
Quality Assurance & Testing
Vacuum Integrity Verification
Helium mass spectrometer leak detection tests are done on every system to make sure it works well. Your furnace keeps the vacuum levels needed for contamination-free processes, and leak rates have been shown to be below the standard levels set by the industry.
Thermal Field Validation
Testing done before arrival shows that all heating zones are the same temperature. Validated thermal profiles help your production process by getting rid of cold spots and making sure that melting properties are always the same.
Component Purity Certification
All of the parts inside meet strict standards for cleanliness. It has been proven that graphite heaters and shielding materials have low ash content. This keeps carbon from getting into your silicon melt.
