COLOUR COATED PRODUCTS
Colour coating of coils means continuous applying of paint to flat steel strip (rolled in a coil shape) with polyurethane
rolls using high-tech automation. Colour coated strip is continuously produced on the line as described in the below steps.
Coils are opened, top and back surfaces of the strip are cleaned (by applying a special chemical agent and rinsing it
off), chromated (an operation to increase the corrosion resistance and to enhance the paint adherence). After that the
strip passes through the oven, and the primer is applied to it (paint is applied only to top surface, while back surface
is covered with high adhesive polyurethane back coating paint). Thereafter, the strip passes through another oven.
If colour coating is requested over the primer on both sides, the paint is applied as the last layer and the strip is dried in
the furnace. Depending on the customers request, protecting film may be applied, and the colour coated strip is rolled
in a coil and packed.
Having passed Hot Strip Mill and Continuous Pickling Line, after rolling on Cold Reversing Mill (CRM), full hard products with surface quality and thickness (0.25-2.00 mm) suitable for further processing on HDGL are produced. Zinc coating is applied by continuous annealing followed by immerging of the strip into zinc pot on Hot Dip Galvanizing Line (HDGL) To protect the surface of galvanized products from corrosion, chemical passivation and protective oil may be applied. Products with thickness ranging between 0.25-3.00 mm and width ranging between 800-1530 mm may be produced on Hot Dip Galvanizing Line.

Advantages of Hong Ky High Speed Steel Coil Slitting Line: Thanks to the double slitting system, quick adjusting the clearance of knife blade has achieved.The design brings customer efficiency, long life operation, and safety for user.
1. Double Slitting System:
- Thanks to the double slitting system, quick adjusting the clearance of knife blade has achieved.
- It is efficient because a knife blade set can be done outside the line.
- It has become possible to experimentally cut outside the line before real operation in order to check the accuracy.
- Since all hydraulic piping and electrical wiring are buried underground, the working ground is clean and easy for operator to work.
2. Gear Box:
- Hong Ky high speed steel coil slitting line has 3 gear boxes (Reducer). All gear boxes are designed and manufactured by Hong Ky, then the design became compact and efficient.
3. Scrap disposal:
- It is unique design. It is automatic.
- After winding the scrap, the scrap is automatically dropped on the conveyor, and the scrap is conveyed to the scrap box.
4. Latest advanced mandrel shaft of Tension Reel:
- Hong Ky has adopted one of the advanced and latest Mandrel Shafts Mechanism. The mandrel shaft is designed to minimize the amount of bending when pinching the edge of the metal sheet.
5. Line Design:
- Line design is a crystal of technology that the steel industry has built over several decades.
- It is efficiency, long life, and strong design.
- Hong Ky high speed steel coil slitting line is classified roughly into 12 main parts.
6. Product liability:
- The safety measurement is taken into consideration in order to meet the product liability law.
- Ground hole are fully covered to increase safety for operator.
- The moving parts are covered as much as possible.
7. User-friendly design:
- Hong Ky high speed steel coil slitting line is easy to handle and taken every safety measures.
