The Influence of Electro-Deposition Time to the Distribution of Silicon in Ferrosilicon Alloy

Abstract

As soft magnetic alloy, Si steel has been brought to the attention of the people. When the content of Si is about 6.5%, the magnetic induction intensity is highest, and the wastage of the iron is lowest, with good magnetic energy. Due to the brittleness and poor process-ability of the 6.5% Si silicon, the traditional production process is very difficult to be used for the production. With traditional production process, the content of Si in silicon steel is commonly 0.1% ~ 4.0%, which makes the property of the silicon steel limited. Use molten salt electro-position method to product silicon steel on the basis of silicon steel surface, to lay the foundation for producing 6.5% Si silicon steel. The influence of the process parameters of molten salt electro-position method to the deposit surface morphology and the silicon content distribution from surface to inside shows that along with the increase of the electro-position time, the size of sediment particle on the deposit surface gradually increases. The sedimentary thickness is proportional to the electro-deposition time.
