Pioneering Large-Scale DC Silicon Smelting<\/h2>\n

HANI\u2019s Submerged Arc Furnace for Industrial Silicon<\/strong> technology has achieved a breakthrough in the development of ultra-large DC systems. In silicon smelting<\/strong>, DC technology significantly reduces the skin effect and proximity effect seen in AC furnaces, leading to a much higher power factor and more uniform heat distribution in the SAF industrial silicon<\/strong> hearth. This results in larger production scales and lower environmental impact.<\/p>\n

Our silicon smelting<\/strong> systems are also equipped with a patented “Rotary Shell” technology. In a Submerged Arc Furnace for Industrial Silicon<\/strong>, the rotation of the furnace shell prevents the sintering of materials and promotes the smooth flow of the intermediate SiO gas. This is a critical factor in achieving high recovery rates in the SAF industrial silicon<\/strong> process. Coupled with HANI’s AI-driven refining system, our furnaces ensure the production of consistently high-grade silicon metal.<\/p>\n<\/div>\n
