I. Industrial Attributes of Silicon Steel

Pewagasan silikon, a vital functional material widely applied in power equipment and electric motors, is categorized as a special steel within the iron and steel industry. Regarded as a high-performance specialty product in the steel family, it forms an independent subcategory thanks to its exclusive electromagnetic properties. Strictly speaking, pepejal silikon manufacturing falls under the segmented field of cold-rolled pepejal silikon sheets in the steel industry, and bears only an indirect, distant connection to the non-ferrous metal industry.

II. Industrial Definition of Silicon Steel Production Using Recycled Scrap Steel

Producing silicon steel from recycled scrap steel is comparable to crafting high-end tailored garments from used fabrics. Despite raw materials sourced from scrap recycling channels, the finished products still belong to iron and steel smelting and processing after undergoing multiple procedures including steelmaking, continuous casting, hot rolling and cold rolling. This production workflow fully conforms to the characteristics of the steel smelting sector, so such operations shall be classified under iron and steel smelting.

III. Practical Guidelines for Industrial Classification Judgement

Two core criteria determine the industrial category of a manufacturing activity: first, the primary raw material (iron constitutes the base component of silicon steel); second, the processing technology (a standard complete steel smelting workflow). Even when recycled scraps serve as feedstock, any production involving full smelting procedures is inherently part of the iron and steel smelting industry. Master this simple rule to eliminate confusion over industrial categorization.
