我所在试制钙镁磷肥期间,为了解决白云石、石英石采运困难,在党的领导、关怀和具体帮助下,大胆打破对外国和书本的迷信;结合当前群众性大搞钢铁的实际情况,用高炉炼铁的铁渣,代替大部分白云石和全部石英石,制成铁渣磷肥。产品含枸溶性有效磷9.75%,枸溶性硅酸24.1%。不仅质量超过我们试制的钙镁磷肥,而且比生产钙镁磷肥还有节省燃料、劳力,缩短熔融时间,减轻炉壁腐蚀,容易找到原料等优点。
During my trial of calcium-magnesium phosphate fertilizer, in order to solve the difficulties of dolomite and quartz stone mining, boldly broke the superstition of foreign countries and books with the leadership, care and concrete help of the party; Ironmaking iron slag, instead of most of the dolomite and all quartz, made of iron slag phosphate fertilizer. Products containing Citrus soluble Phosphorus 9.75%, 24.1% citric acid soluble silicate. Not only the quality of our trial production of calcium magnesium phosphate, but also than the production of calcium magnesium phosphate fertilizer and fuel savings, labor, shorten the melting time, reduce furnace corrosion, easy to find the advantages of raw materials.
