High Purity Ferro Silicon FeSi65-72
An alloy of iron and silicon. Ferrosilicon is mainly used as a deoxidizer and alloy additive in steelmaking, and is also used in casting, beneficiation, welding rod, light metal industry and as a reducing agent for smelting certain metals. The main raw material of smelting ferrosilicon is silica ore (quartz, silica), SiO2 in the ore is generally higher than 96%, smelting high silicon ferrosilicon is higher than 98%, P2O5 in the ore generally should not exceed 0.02%, Al2O3 should not exceed 1.5%. The commonly used varieties of ferrosilicon contain 45%, 75% and 90% silicon.

Products Description
Ferrosilicon is widely used in steel industry, casting industry and other industrial production. Ferrosilicon is an essential deoxidizer in steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel, improve the permeability of steel, and reduce the hysteresis loss of transformer steel. Low aluminum ferrosilicon is a special use of ferrosilicon in recent years, its smelting process is complex, high added value of products, is the ferrosilicon manufacturers actively explore the field. Examples of ferrosilicon applications are as follows:
1) Adding ferrosilicon powder to reduce the powder rate of ferrochrome alloy, the method includes the following steps: Select the particle size generated in the crushing process of ferrosilicon alloy is 5? 10mm ferrosilicon powder as raw material; Ferrosilicon powder is added to the hot metal ladle during the ferrochrome alloy baking process, and the amount of ferrosilicon powder added is 0.5? 1.0kg/t, when added, 1/3 of the total amount of ferrosilicon powder is added when the ferrochrome alloy is baked to 1/4, 1/3 of the total amount of ferrosilicon powder is added when the ferrochrome alloy is baked to 1/2, and 1/3 of the total amount of ferrosilicon powder is added when the ferrochrome alloy is baked to 3/4. On the one hand, the invention can prevent the formation of bubbles, so as to obtain dense iron ingot, effectively reduce the powder rate of ferrochrome alloy, improve the production technical and economic indicators of ferroalloy enterprises, and greatly reduce the production cost of ferrochrome alloy. On the other hand, the ferrosilicon powder is produced in the crushing process of ferrosilicon alloy, which realizes the recycling of resources, meets the requirements of energy conservation and environmental protection, and will not cause environmental pollution and energy waste, and the method is easy to implement, simple and convenient.
2) A ferrosilicon ball is prepared, which is made of ferrosilicon raw materials and adhesives. The raw materials of ferrosilicon are ferrosilicon powder or a mixture of ferrosilicon powder and metallic silicon powder; The content of silicon in ferrosilicon powder is 72-75%, and the content of silicon in metallic silicon powder is 72-85%. The adhesive is made of water, quartz sand, alkali, fluorite, silica powder and micro-silica powder, and its modulus is 3-3.7. The diameter of the ferrosilicon powder ball is 10-80mm. The product is a raw material of ferrosilicon, mixed with a binder specially used for the manufacture of the product, using the pelleting mechanism, there is no need to re-furnace smelting, the composition of each substance in the manufacturing process will not change, so it is easy to control the silicon content of the product; The ferrosilicon powder and metallic silicon powder used in manufacturing can be made of the powder remaining after the crushing of export products, so the existing resources in China are saved, and the use is also very convenient.
