Products Description

Silicon also has the important physical properties of low electrical conductivity, poor thermal conductivity and strong magnetic conductivity. Therefore, when refining silicon steel (containing about 2 to 4% silicon), ferrosilicon can be used as an alloying agent. Silicon steel sheet is one of the power industry materials, using it as the core of transformers and motors, hysteresis loss can be greatly reduced, and can meet the technical requirements of transformers and motors. If the ordinary carbon steel sheet is used as the iron core instead of the silicon steel sheet, the heat output of the transformer and the motor is increased by 3 to 6 times. This reduces the power factor of the equipment, and also causes the overheating of the equipment, so that it cannot operate normally.

Ferrosilicon is a kind of ferroalloy widely used. It is a ferrosilicon alloy composed of silicon and iron in a certain proportion, and is an indispensable material for steelmaking. Ferrosilicon is a deoxidizing agent for steelmaking and an alloying agent for smelting silicon steel. When smelting spring steel and heat-resistant steel, a certain amount of ferrosilicon should also be added as alloying agent. Production practice has proved that oxygen in steel will significantly deteriorate the properties of steel and reduce the mechanical properties of steel. Therefore, the process of steelmaking must be deoxidized. Oxygen exists in steel as ferrous oxide (FeO). Silicon is an element that binds very well to oxygen.

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.
