Manufacturing process of cold rolled non-grain oriented electrical silicon

In the realm of manufacturing, the process by which cold rolled non-grain oriented electrical silicon is produced encompasses a series of pivotal steps, all of which contribute to the creation of a superior material for electrical applications.

A. Overview of the production process

At the outset, the production process commences with the careful selection of the finest silicon, chosen for its superior quality. This chosen silicon is then subjected to the heat of a furnace, where impurities are expelled, leaving behind a desired chemical composition. The molten silicon, now purified, is transformed into thin slabs through the continuous casting process.
