The main raw material of the calcium silicon cored wire is silicon calcium powder. The silicon calciumpowder is used as the core material, and the outer skin is steel skin, It is pressed by a professionalcrimping machine.

In the process of making the silicon calcium cored wire, It must pay attention towhether the steel is in the process. The skin is tightly covered, and there is no leakage, whether thecore material is evenly filled. The above attention must be strictly checked. A problem with the ringwill affect the quality of the entire silicon calcium core wire.
