摘　　要：以纯氟磷灰石、硅石和碳为例，电炉法制磷过程中，将原料从常温（20℃）升至1300K所需的热量，是从1300K继续加热升温至1725K所需热量的2．14倍。如果1300K前用动力煤加热，1300K以上才用电能加热，单从加热过程看，按当前贵州黄磷行业的电价及一般动力煤价计，成本可节约一半以上。During the electric furnace production process, the power needed while heating the material such as pure fluorapatite, silica and carbon, from 20℃ to 1300K 2.14 times that from 1300 K to 1725 K. If low - quality source （ such as thermal coal ） is used during the front process, and the high - quality（ such as electrical power） for the next step, it will save more than half electricity cost during the heating process in Guizhou phosphorus industry.
