The ferro silicon ball is made of ferro silicon powder and silica slag powder by scientific pressing, the composition is unchanged and the silicon content is 40% and the cost is reduced. Used for steel slag back smelting pig iron, ordinary casting, etc., can improve the furnace temperature, increase the fluidity of hot metal, effectively remove slag, increase the label, improve the toughness and cutting ability of pig iron and castings. The ferro silicon ball may also contain a small amount of aluminum, calcium, manganese, magnesium and other impurity elements. The content and proportion of these elements will vary according to different processes and needs. The whole particle size of ferro silicon ball is uniform, the use of fuel saving, melting speed, uniform division, is the best material for smelting pig iron and ordinary casting.
The role of ferro silicon ball in metallurgical industry
Ferro silicon balls play an important role in the metallurgical industry, mainly reflected in the following aspects
The silicon element in the ferro silicon ball can react with the oxygen in the iron to produce silicon dioxide, thereby reducing the impurity content in the iron and improving the purity and quality of the iron. The silicon in the ferro silicon ball can also react with the carbon in the iron to form silicides, further increasing the strength and hardness of the iron, making it more suitable for the manufacture of high-strength steel.
The silicon element in the ferro silicon ball can form compounds with other elements in the iron, thus regulating the composition of the iron. For example, silicon can form a silicon-manganese alloy with manganese in iron, improving the wear resistance and corrosion resistance of iron; Silicon can form a silico-vanadium alloy with the vanadium in iron, improving the strength and heat resistance of iron. By adding an appropriate amount of ferro silicon ball, the composition of iron can be adjusted according to needs, so that it has better performance and application value.
The silicon element in the ferro silicon ball has a high melting point, and the melting point of the iron can be reduced by adding an appropriate amount of ferro silicon ball, so that it is easier to melt and cast. The silicon in the ferro silicon ball can also improve the fluidity of iron, reduce pores and defects in the casting process, and improve the molding quality of iron.
The addition of ferro silicon balls can promote the chemical reaction in the smelting process and improve the smelting efficiency. The silicon element in the ferro silicon ball can react with the oxygen in the iron to produce silicon dioxide, thereby reducing the oxygen content in the smelting process and speeding up the smelting speed. The silicon in the ferro silicon ball can also react with the sulfur in the iron to form silicates, thereby reducing the sulfur content in the iron and improving the purity and effect of smelting.
The use of ferro silicon balls can save energy and resources. The silicon element in the ferro silicon ball has a high reducibility and can react with the oxygen in the smelting process to produce silicon dioxide, thereby reducing the consumption of oxygen and the use of fuel. The silicon in the ferro silicon ball can also form compounds with the impurity elements in iron, thereby reducing the content of impurities and improving the utilization of resources.
Ferro silicon ball is widely used in metallurgical industry because of its excellent performance and wide application fields. Ferro silicon balls can be used to make steel, cast iron and alloy materials, widely used in automobile manufacturing, aerospace, machinery manufacturing, construction engineering and other fields. Ferro silicon balls can also be used as auxiliary materials such as metallurgical charges and desulfurizers to improve the effect and quality of the smelting process.
Ferro silicon ball is an alloy material composed of two main elements, silicon and iron, which plays an important role in metallurgical industry. Ferro silicon balls can improve the quality of iron, adjust the composition of iron, reduce the melting point and improve fluidity, improve smelting efficiency, save energy and resources, and the application field is also very wide. With the continuous development of metallurgical technology, the role of ferro silicon balls in the metallurgical industry will be more and more important.
