Silicon ball is a new type of ferro alloy products, silicon ball manufacturers by different silicon content of silicon powder pressed by the ball equipment, silicon ball as a new metallurgical material is widely used in many industries, especially in the steelmaking industry.
1, adding a certain number of silicon balls in steel, can improve the strength, hardness and elasticity of steel, so in the smelting of structural steel, tool steel, spring steel, and transformer silicon steel, iron silicon is also used as an alloying agent. It is used as inoculant and nodulator in the cast iron industry.
2, the addition of a certain amount of silicon in cast iron can prevent the formation of carbide in iron, promote the precipitation and nodulation of graphite, so in the production of ductile iron, silicon ball is an important inoculant (to help precipitate graphite) and nodulation agent.
When smelting silicon balls, one is the presence of excess fuel flame in the small furnace smelting process metallurgical products, the second is the presence of silica rich due to the poor melting in the raw material. Only when these two conditions are met, can the prerequisite for the production of silicon balls be achieved.
In addition to having a strong deoxidation effect, silicon balls also have good heat resistance and electrical conductivity. There is no single silicon in the silicon ball, which is mainly due to the high temperature of the furnace in the process of smelting the silicon ball, resulting in the combustion of single silicon to form silicon oxide. Steelmaking is a huge industry. In the process of steelmaking, manufacturers add silicon balls, which are mainly used for oxygen deoxidation in molten steel to improve the hardness and quality of steel.
In steelmaking, silicon ball is a new type of composite metallurgical materials, its price is lower than the traditional metallurgical materials, but can achieve good results, silicon ball and silicon carbide have the characteristics of fast deoxidation speed, good slag collection, and silicon ball compared with the traditional metallurgical materials, the price is lower, in use can often greatly reduce the cost of metallurgy, improve the efficiency of metallurgical manufacturers. Therefore, manufacturers purchase more silicon balls to replace traditional metallurgical materials, mainly in order to save production costs and increase profits.
When choosing silicon ball products, the following points need to be considered:
The appropriate particle size should be selected according to the actual application needs, the smaller the particle size, the larger the specific surface area of spherical silicon, the higher the activity, but at the same time the higher the manufacturing cost.
The purity of spherical silicon has an important impact on its performance, the higher the purity, the better its electrical conductivity, thermal stability and other properties. Therefore, when selecting, spherical silicon products with high purity should be selected as far as possible.
The surface treatment of spherical silicon also has an important impact on its application performance, such as surface modification can improve its dispersion and compatibility, and reduce agglomeration. Therefore, in the selection, should try to choose the surface treatment of silicon ball products.
