Low Aluminum Ferro Silicon FeSi75Al

Low aluminum ferro silicon is an alloy product primarily composed of silicon, iron, and a small amount of aluminum. It is an important flux and widely used in steelmaking and foundry industries. It plays a crucial role in steel production, effectively removing iron oxide and other impurities, thereby improving the purity and quality of steel.

The main components of low-aluminum ferrosilicon are silicon and iron, with silicon content generally ranging from 40% to 60% and iron content from 30% to 50%. The aluminum content is generally below 1%, hence the name "low-aluminum ferrosilicon." FeSi exhibits excellent reducing and deoxidizing properties, effectively absorbing and removing harmful impurities such as manganese and sulfur, thereby improving the purity and strength of steel.

In steelmaking, FeSi is commonly used as an additive, added to the charge to promote reduction and alloying reactions. It stabilizes furnace temperatures, reduces slag volume, reduces energy consumption, and improves smelting efficiency. It also improves the fluidity and wettability of molten steel, reduces gas and slag inclusions, and enhances the formability and mechanical properties of steel.

In general, low-aluminum ferrosilicon is an important steel alloy product with good reducibility, deoxidation and alloying properties. It can improve the quality and output of steel and is widely used in steel smelting and casting industries.

A new method for smelting low-aluminum ferrosilicon (FeSi) that reduces power and coke consumption. This method replaces steel scrap entirely with an iron-containing material composed of oxides such as Fe2O3, Fe3O4, and FeO. The smelting charge consists of silica, metallurgical coke , and iron oxide, tailored to the silicon content of the ferrosilicon required by the design . This method, unlike existing methods for producing low-aluminum ferrosilicon, features a first step in which the iron oxide and metallurgical coke are evenly mixed; this is then combined with silica to form a mixed charge.

First, the iron oxide material and the coke particles are mixed evenly to ensure their close contact, thereby ensuring that the iron oxide is reduced earlier than the silicon dioxide in the silica , thereby avoiding the reaction of the iron oxide with the silicon dioxide in the silica to form a low-melting-point iron silicate melt, maintaining the high temperature that the melt should have, and avoiding the defect of lowering the melt temperature that is easily caused by the iron oxide material replacing the steel chips.

The new process ensures that the resistance value of the entire charge in the furnace is uniform, the electric field is evenly distributed, the insertion depth of the three electrodes is balanced, the current of the three-phase electrodes is balanced, the power distribution of the three-phase electrodes is even, and the temperature field in the furnace is uniform. This ensures that the three crucible reaction zones formed by the ends of the three electrodes buried in the charge are at approximately the same horizontal height in the furnace, which is beneficial to the communication between the three crucibles, the aggregation of low-aluminum-silicon ferromagnetic liquid, and the stability of the iron outlet position.

Depending on the needs of different customers and production process requirements, the chemical composition of low aluminum silicon ferrosilicon can be adjusted to meet the specific requirements of different steels and alloys. We provide low aluminum silicon ferrosilicon in different specifications and composition ratios to ensure that customers get the best solution for their production needs.

Excellent Deoxidation Performance
Low-aluminum ferrosilicon has a strong deoxidation capacity, which can effectively remove oxygen from molten steel during the steelmaking process, reduce oxide formation, and improve the purity of the steel. This makes it an essential alloy material for the production of high-quality alloy steel and stainless steel.

Significant alloying effect:
The aluminum component in low-aluminum ferrosilicon can form stable compounds during steelmaking, enhancing the steel's oxidation resistance, corrosion resistance, and high-temperature resistance. It is particularly suitable for the production of high-temperature alloys, heat-resistant alloys, and high-strength steel.

Improving the overall performance of steel
