The production of 75 Ferrosilicon uses natural silica as raw material, metallurgical coke as reducing agent and a certain amount of iron-containing material for smelting in a submerged thermal electric furnace. At present, the iron-containing material added to the production of 75 Ferrosilicon is carbon steel scraps, and the amount added is less than that of silica and coke. In addition, the particle size of the steel scraps is difficult to guarantee, which inevitably causes uneven distribution of steel scraps in the furnace, causing uneven distribution and frequent fluctuations of the resistance value in the furnace, and it is difficult to stabilize the consistency of the electrode and alloy composition.
The particle size range of 75 Ferrosilicon natural blocks is from 100mm to above, and the specific size may vary depending on the supplier, production batch and purpose.
In practical applications, the size selection of 75 Ferrosilicon natural blocks usually depends on the specific usage scenario and process requirements. For example, in the steelmaking industry, 75 Ferrosilicon natural blocks as deoxidizers and alloying agents may require a specific particle size to ensure their uniform distribution and reaction effect in molten steel. In the foundry industry, 75 ferrosilicon natural blocks as inoculants may require smaller particle sizes to better integrate into cast iron and improve its microstructure.
High-quality 75 ferrosilicon natural blocks should have high silicon content, stable chemical composition, good physical properties and low impurity content. These quality standards are essential to ensure the performance of 75 ferrosilicon natural blocks in various industrial applications.
75 ferrosilicon natural blocks are important deoxidizers and alloying agents in the steelmaking industry. It can effectively remove oxygen from molten steel and improve the purity and quality of steel. At the same time, by adjusting the proportion of ferrosilicon, the chemical composition and physical properties of steel can also be changed, such as improving strength, hardness and corrosion resistance.
In the foundry industry, 75 ferro silicon natural blocks are often used as inoculants, which can improve the microstructure of cast iron and improve the mechanical properties and process properties of cast iron.
75 ferro silicon natural blocks are also one of the important raw materials in the ferroalloy industry, used to produce other ferro alloy materials.
Other applications: In addition, 75 ferrosilicon natural blocks can also be used to manufacture refractory materials, chemical raw materials and semiconductor materials, etc.
