我厂生产磷铁已有30多年的历史。近几年来,为了降低原材料消耗,降低电耗,提高磷的回收率,降低产品成本,我们对磷铁生产工艺进行了一些改进,收到了较好的效果。现将有关情况介绍如下。一、改变渣型我厂磷铁生产中的炉渣原为碱性渣,其代表性成分为(％):P 2.0,CaO 45,SiO_2 Phosphorus iron plant I have 30 years of history. In recent years, in order to reduce the consumption of raw materials, reduce power consumption, increase phosphorus recovery, reduce product costs, we made some improvements to the production of phosphorus and iron, received good results. The relevant information is as follows. First, change the slag type slag plant in the production of iron phosphate was originally alkaline slag, its representative composition (%): P 2.0, CaO 45, SiO 2
