Yellow phosphorus smelting furnace is a kind of equipment used to extract and refine yellow phosphorus, which is widely used in the smelting of phosphorus ore. It uses high-temperature melting and special separation technology to separate yellow phosphorus from phosphate rock and achieve the purpose of refining. The working principle of the yellow phosphorus smelting furnace is to realize the extraction and refining of yellow phosphorus through the melting and separation of phosphate rock at high temperature. First, put the phosphate rock into the smelting zone of the furnace, and heat the phosphate rock to melt at high temperature. During the smelting process, the yellow phosphorus is separated from the ore and collected in a collector at the bottom of the furnace. While smelting, use separation technology to separate and remove impurities and harmful components in phosphate rock. Finally, the yellow phosphorus goes through storage, condensation and other process steps to obtain high-purity yellow phosphorus finished product. Yellow phosphorus smelting furnace has the following salient features. First, it uses high-temperature melting to effectively extract yellow phosphorus from phosphate rock. Secondly, the yellow phosphorus smelting furnace adopts special separation technology, which can effectively remove impurities and harmful components in phosphate rock. Thirdly, the yellow phosphorus smelting furnace has the characteristics of high efficiency and energy saving. It adopts advanced heating methods and energy-saving measures to reduce energy consumption and improve production efficiency. Finally, the yellow phosphorus smelting furnace has an automatic control system that can achieve precise temperature and pressure control to ensure the stability of the smelting process and product quality.
