1. lnput Process: Equipment at the entry point of the electrogalvanizing line consists of a pay-off reel, a shearing M/C, a welding M/C, a looper and a tension leveler. The pay-off reel transports stacked or cold rolled steel materials to the shearing machine which cuts and connects them in preparation for welding. Then comes the welding.
2. Pre-Treatment Process: An electrolytic cleaning line consists of an electrolysis tank, an acid bath and a rinse tank to remove contaminants and oxide films from the surface of the steel before electroplating.
3. Electrical Galvanizing: The CAROSEL method, among other electric galvanizing, involves the plating of one side at a time by means of a conductor roll. This process produces two-sided, single-sided, differential-sided plated sheets. There is also the horizontal type where two sides of a sheet are plated at the same time to produce a two-sided plated sheet.

1. Pre-Treatment Process: Some rolling oil and other contaminants remain on the surface of cold rolled steel sheets following processing. These are removed by passing the electrically charged sheet through an alkaline solution which induces an electrochemical reaction.
2. Annealing: The material properties of the pre-treated steel sheet can be altered and improved through recrystallization during the annealing process.
3. Hot-Dip Galvanizing: After passing through the annealing furnace, steel sheets are dipped into a zinc pot where molten Zn is coated onto the surface. The desired coating weight is achieved by removing excess zinc before solidification with high-pressure air from an air knife.

1. Preliminary Annealing: During the preliminary annealing process, a scale which may have formed on the hot rolled steel is removed as delayed passing through scale breaker and a hydrochloric acid bath. This initial heat treatment process improves the cold rolling properties of steel as well as its magnetic properties.
2. Cold Rolling: In order to obtain specific thickness and material properties, a reduction ratio of 40-90% is applied normally. Rolling and edge trimming machines are automatically controlled to obtain uniform thickness and width.
3. Annealing: Annealing is a process in which cold rolled structures are converted to a recrystallized structure through heat treatment. For grain oriented electrical steel, two different annealing methods are available: decarbonization annealing and high-temperature annealing. Decarbonization annealing removes excess carbon from the steel and applies a MgO coating. High-temperature annealing produces secondary recrystallized structures having superior magnetic properties.

1. Reheating: Hot rolled coils pass through a pickling line, where scale breaker machines and hydrochloric acid solutions are used to remove any surface scale and/or oxide film that which causes surface flaws during the final stage of cold rolled steel processing.
2. Roughing: In this process, slabs whose surface scale share has been removed are made into rolled materials with the proper shape, thickness, and width. In the entry and exit area of the roughing mill, an edger rolls the strip in the width direction using an Automatic Width Control (AWC) system.
