1、 Definition and purpose

Silicon steel sheet iron coil is a type of coil material made mainly from silicon steel sheets, mainly used for manufacturing iron cores in electrical equipment such as motors, generators, and transformers. Due to its excellent magnetic and mechanical properties, silicon steel sheets and coils have become indispensable and important materials in industries such as power, electronics, and communication.

2、 Manufacturing process

The manufacturing process of silicon steel sheets and coils mainly includes the following steps:

Smelting: Mix raw materials such as silicon iron, manganese iron, and chromium iron in a certain proportion, add an appropriate amount of scrap steel, and send them into an electric furnace for smelting.

Rolling: Pour the refined molten steel into the rolling mill for rolling to obtain steel plates with a certain thickness and width.

Coating: Apply a layer of insulation coating on the surface of the steel plate to improve its insulation performance.

Heat treatment: The coated steel plate is subjected to high-temperature annealing treatment to eliminate internal stress and improve its mechanical properties.

Cutting: Cut the heat-treated steel plate to obtain the required size and shape.

Splicing: Splicing the cut steel plates to create the required length of coil.

Quality inspection: Conduct quality inspection on the roll material, and package it before leaving the factory after passing the inspection.
