Product Description
Yellow Phosphorus Smelting Furnace (Phosphorus Production Electric Furnace)
High Efficiency & Energy Saving · High Phosphorus Recovery · Sealed & Eco-friendly · Stable Mass Production
The yellow phosphorus smelting furnace, also known as phosphorus production electric furnace, is the core equipment for thermal-process yellow phosphorus production. It adopts a three-phase sealed arc furnace structure, in which phosphate rock, silica and coke undergo reduction reaction at 1300–1500℃ to produce phosphorus vapor, which is then condensed and refined into industrial yellow phosphorus. It is widely used in phosphorus chemical industry, fine chemicals, pesticides, flame retardants, and lithium battery raw materials.
1. Equipment Composition
