<\/p>\n

\n

Engineered for High-Purity Elemental Phosphorus<\/h2>\n

The Yellow Phosphorus Smelting Furnace<\/strong> is a critical industrial unit used to extract yellow phosphorus (P4) from phosphate rock. As a specialized Yellow Phosphorus Furnace<\/strong>, it utilizes a high-temperature reduction process involving phosphate rock, silica, and coke. At HANI<\/strong>, we have developed advanced phosphorus smelting<\/strong> technologies that integrate fully enclosed designs with state-of-the-art gas condensation systems. Our SAF for yellow phosphorus<\/strong> is engineered to deliver maximum extraction efficiency and energy savings, providing a stable platform for the production of high-purity yellow phosphorus used in the chemical, food, and pharmaceutical industries.<\/p>\n

A HANI Yellow Phosphorus Smelting Furnace<\/strong> is designed for ultra-low emission and high reliability. The Yellow Phosphorus Furnace<\/strong> must handle the complexities of phosphorus gas (P4) capture and separation from slag and ferrophosphorus byproducts. Our phosphorus smelting<\/strong> units are equipped with fully automatic charging, electrode management, and furnace interior monitoring. By integrating hot-charging technology and high-efficiency gas purification, HANI\u2019s SAF for yellow phosphorus<\/strong> ensures the highest automation level in the industry, meeting the most stringent global standards for safety and product quality.<\/p>\n<\/div>\n

Chemical Process of Yellow Phosphorus Smelting<\/h2>\n

The production of yellow phosphorus in a Yellow Phosphorus Smelting Furnace<\/strong> is based on the carbothermic reduction of fluorapatite [Ca5(PO4)3F] or hydroxyapatite. In the Yellow Phosphorus Furnace<\/strong>, silica (SiO2) is added as a flux to combine with CaO to form a liquid slag, while coke (C) reduces the phosphorus to its elemental gas form. HANI’s phosphorus smelting<\/strong> technology ensures the precise control of the furnace temperature (1300-1500\u00b0C) in the SAF for yellow phosphorus<\/strong>.<\/p>\n

Overall Reduction Reaction:<\/p>\n

2Ca3<\/sub>(PO4<\/sub>)2<\/sub> + 6SiO2<\/sub> + 10C \u2192 6CaSiO3<\/sub> + P4<\/sub>(g) + 10CO(g)<\/p>\n<\/div>\n

To achieve high phosphorus purity and recovery in the Yellow Phosphorus Smelting Furnace<\/strong>, the removal of impurities like iron and aluminum oxides is critical. HANI’s phosphorus smelting<\/strong> process produces ferrophosphorus as a valuable byproduct, which is tapped separately. Our SAF for yellow phosphorus<\/strong> is also equipped with a multi-stage condensation system that cools the P4 gas to its liquid state, ensuring a safe and efficient collection process.<\/p>\n<\/div>\n
