Why should the silicon steel sheet be rustproof?
The composition of silicon steel sheet is composed of Fe and Si. If oxidized, iron oxide or iron oxide is generated, that is to say, the material of silicon steel is changed, which has certain influence on the performance of the finished product.
Most of silicon steel is cold-rolled silicon steel. Both are coated, and if the rust coating is broken, it won't work.
Silicon steel is also a kind of ordinary steel, and its corrosion degree in air is more than that of ordinary medium carbon steel, especially after cutting, it is easier to rust.The current steel products in the factory is used edge sealing agent (a antirust oil), some of the current motor factory or punching processing enterprises without the use of this technology in the silicon steel sheet punching, also failed in the process to other processes (such as gas phase anti rust treatment), silicon steel sheet is rust it is a normal phenomenon.
