Si-al-fe alloy is a kind of deoxidizer used in steelmaking. It is an effective new technology to improve the quality of steel, reduce the cost and save aluminum by improving the inclusions and reducing the content of gas elements in liquid steel. According to the raw material treatment method, there are two kinds of ore reducing agent, directly into the furnace after batching and first through mass treatment and then into the furnace.
Ferro Silicon Aluminum uses
Silicon aluminum and iron in the steelmaking industry can improve some of the mixed with some stuff, but also reduce the gases in the molten steel element, has the very good products, to improve the quality of steel can improve steel quality can also reduce the cost, and can save use of new technology of aluminum so well suited for use in steelmaking, and also got a very wide range of applications. Continuous casting steel deoxidation requirements, the practice has proved that it not only meets the requirements of steel deoxidation, but also has the desulfurization performance and has the advantages of heavy, strong penetration and so on.
Si-al-ferroalloy is a strong deoxidizer and a reducing agent in the production of other metals and alloys. It is also used in thermite welding, the manufacture of heating agents and explosives.
Advantages of Ferro Silicon Aluminum
1. The practical application of silicon aluminum ferro alloy deoxidation proves that the effect is good. Compared with aluminum deoxidation, not only the aluminum yield is high, the residual aluminum is easy to control, and the shape of inclusions is also improved;
2. After using silicon aluminum alloy, the element recovery rate is high, mainly because the proportion of alloy increases, the proportion of aluminum is 2.7g/cm3, the proportion of silicon aluminum ferro is 3.5-4.2g/cm3, and the proportion of final steelmaking slag is generally 2.8-3.2 g/cm3, so the alloy will sink below the slag surface after being added, effectively controlling the reaction of aluminum with air and oxygen in the slag.
3. The deoxidation effect is good. It is generally believed that complex deoxidation products are formed, and the activity of oxides is reduced, which is conducive to the deoxidation reaction.
4. It is easy to form a low melting point, which makes the inclusions easy to aggregate and promotes floating removal. When deoxidizing with silicon aluminum ferro respectively, the total aluminum content in the steel is higher in the former than in the latter, while the acid-soluble aluminum in the latter is higher than that in the former, which shows that when ferrosilicon is used, the aluminum oxide inclusions are greatly reduced.
