I. From Iron Ore to Hot-Rolled Coils<\/h2>\n

The production of \u09b8\u09bf\u09b2\u09bf\u0995\u09a8 \u0987\u09b8\u09cd\u09aa\u09be\u09a4<\/a> sheets starts with smelting iron ore. After blast furnace ironmaking and converter steelmaking, an appropriate proportion of silicon (normally 1%\u20133%) is added to form crude \u09b8\u09bf\u09b2\u09bf\u0995\u09a8 \u0987\u09b8\u09cd\u09aa\u09be\u09a4<\/a> slabs. Hot rolling serves as the first critical working procedure:<\/p>\n

    \n
  1. Heat steel slabs to approximately 1200 \u00b0C<\/li>\n
  2. Reduce thickness from 200 mm to 2\u20133 mm via multi-pass rolling<\/li>\n
  3. Control the finish rolling temperature above 800 \u00b0C<\/li>\n
  4. Coil the strip into hot-rolled coils for subsequent processing<\/li>\n<\/ol>\n

    This stage is comparable to repeatedly rolling dough; uniform distribution of silicon elements directly governs the electromagnetic performance of finished products.<\/p>\n

    II. Precision Fabrication via Cold Rolling and Annealing<\/h2>\n

    Core sophisticated processing takes place in the cold rolling workshop:<\/p>\n

      \n
    1. Pickling: Remove scale on hot-rolled coil surfaces with hydrochloric acid<\/li>\n
    2. Cold rolling: Roll steel strips down to 0.2\u20130.5 mm at ambient temperature<\/li>\n
    3. Intermediate annealing: Heat strips to 800 \u00b0C under hydrogen atmosphere to eliminate work hardening<\/li>\n
    4. Secondary cold rolling: Roll strips to target thickness with dimensional tolerance controlled within \u00b10.01 mm<\/li>\n<\/ol>\n

      Annealing is an extremely vital process, equivalent to a conditioning treatment for \u09b8\u09bf\u09b2\u09bf\u0995\u09a8 \u0987\u09b8\u09cd\u09aa\u09be\u09a4<\/a>. Precise regulation of temperature and holding time enables grain recrystallization and rearrangement to form an optimized magnetic domain structure.<\/p>\n

      \"\u09b8\u09bf\u09b2\u09bf\u0995\u09a8<\/h2>\n

      III. Finishing and Performance Control<\/h2>\n

      Final processes define the characteristic performance of silicon steel sheets:<\/p>\n

        \n
      1. Coating treatment: Apply micron-scale insulating coatings capable of withstanding temperatures up to 800 \u00b0C<\/li>\n
      2. Laser scribing: Etch micro grooves on the surface with laser beams to cut core loss<\/li>\n
      3. Magnetic performance inspection: Every coil undergoes testing with an Epstein frame<\/li>\n
      4. Slitting and packaging: Cut coils into customized dimensions per customer requirements<\/li>\n<\/ol>\n

        These elaborate procedures are akin to surface finishing and quality inspection for silicon steel, guaranteeing stable operation inside transformers and motors.<\/p>","protected":false},"excerpt":{"rendered":"
