Ferrophosphorus is obtained from phosphorus-making electric furnaces and has a honeycomb-like surface. It is a symbiotic compound containing 26-28% phosphorus and 0.1-6% silicon. The quality and chemical composition specifications of ferrophosphorus during production are within a certain standard range, which results in a relatively uniform particle size of ferrophosphorus, thereby better reducing the loss of natural block crushing of ferrophosphorus in steelmaking, and What a waste of other resources!
The physical properties of phosphorus iron are very similar to those of pure iron, but their chemical properties are quite different. The chemical properties of iron phosphorus are very active and easy to be oxidized and corroded, but it also has strong corrosion resistance and wear resistance. These special properties make ferrophosphate suitable for various industrial fields.
The production process of ferrophosphate mainly includes two steps: ore beneficiation and smelting. First, the ore raw materials containing phosphorus are extracted from the phosphate rock, such as apatite, phosphorite, siderite, etc. Then, under high temperature conditions, the ore and reducing agents such as coke are put into a blast furnace or electric furnace for smelting, and ferrophosphorus is generated through a reduction reaction. During the smelting process, certain fluxes and desulfurizers can also be added as needed to improve the purity and product quality of ferrophosphorus.
One of the main uses of ferrophosphate is in the steelmaking process. In the steelmaking process, raw materials such as limestone and coke are added to the steelmaking furnace together with ferrophosphorus, and liquid ferrophosphorus is generated through a high-temperature reaction. Ferrophosphorus has high solubility in molten steel and can effectively reduce and adsorb impurities, sulfur, phosphorus and other substances in the steel, thereby improving the purity and quality of the steel. Ferrophosphorus can also prevent the formation of bubbles in steel, improve the structural structure of steel, and increase the strength and toughness of steel.
In addition to its use in the steelmaking process, ferrophosphorus also plays an important role in the production of metallurgical alloys. Ferrophosphorus can be combined with other metal elements to synthesize phosphorus-containing alloys, such as low-phosphorus ferrochromium, low-phosphorus ferromanganese, etc. These phosphorus-containing alloys are widely used in industrial production, such as stainless steel production, manganese alloy production, etc. Phosphorus-containing alloys can improve the wear resistance, corrosion resistance and strength of metal materials and are widely used in automobile manufacturing, aerospace, construction and other fields.
As a special alloy material, ferrophosphorus plays a very important role in future industrial production and technological applications. Its special properties and excellent performance make iron phosphorus one of the most widely used materials in the future. We believe that with the continuous development and advancement of science and technology, iron phosphorus will have increasingly broad application prospects.
