Iron Phosphorus Granules

Ferrophosphate acts as a phosphorus additive in steelmaking and casting. Phosphorus is a harmful impurity in most steel grades, but it can improve the corrosion resistance of some steel grades.

When steel plates containing phosphorus are used, adhesion between steel plates can be prevented. When producing rolls, adding 0.4%-0.5% phosphorus can improve fluidity and avoid surface cracks. Phosphorus can also improve and enhance the cutting performance of steel. These are the uses of ferrophosphorus in steelmaking.

The use of phosphorus iron in casting can improve the fluidity of cast iron, thereby improving the quality of castings. When producing high-phosphorus wear-resistant cast iron, phosphorus forms a uniform binary phosphorus eutectic structure in the casting and is distributed in a network. Due to the high hardness of phosphorus eutectic, truck brake shoes contain 0.7%-1% phosphorus to improve their wear resistance. Currently, most uses of ferrophosphate are in the foundry industry.

There are many kinds of phosphorus minerals in nature, and the ores suitable for industrial production mainly include apatite and phosphate rock. Apatite is a widely distributed mineral, and the main mineral in Hanlin is fluorapatite. Globally, phosphate rock resources are mainly distributed in Africa, North America, South America, Asia and the Middle East. More than 80% of phosphate resources are concentrated in Morocco and Western Sahara, South Africa, the United States, China, Jordan and Russia. At present, my country's annual output of phosphate rock exceeds 60 million tons, much higher than that of countries such as the United States, Morocco and Western Sahara.
