1. The characteristics of good metal silicon 553 in terms of content: the national standard metal silicon 553 requires that the content of iron element accounts for 0.5%, aluminum element accounts for 0.5%, calcium content accounts for 0.3%, and the content of silicon in metal silicon should be as high as 98.5%, which has a good effect in steel making and deoxidation. When purchasing metal silicon 553, you can also ask the metal silicon manufacturer for samples for analysis. Good metal silicon 553 should have the content requirements standard.
2. The characteristics of good metal silicon 553 in terms of price: The metal silicon 553 can be divided into oxygen free metal silicon 553 and oxygen free metal silicon 553 in terms of product price. Generally, the price of oxygen free metal silicon 553 is about 12000 yuan/ton, while the price of oxygen free metal silicon 553 is about 11000 yuan/ton. If the price quoted by the manufacturer of metal silicon 553 is far from the standard price, It should be noted that the reliability of the manufacturer's metal silicon 553 products.
