1 Coil Processing Mike Gabor Cortec Corporation

2 What is a Coil Processor A company that processes steel Slitting, Cut to Length applications, Pickling, Tension Leveling, Galvanizing, Annealing, Tempering and other applications

3 Coil Processors Current Customers in Ohio and Indiana Worthington Steel Ferrous Metals Steel Technologies Blair Strip Steel Stripco

4 How we can help Cortec provides rust preventatives that can be applied in most applications to protect steel After pickling Wet tempering In process Edge spray Packaging

6 Pickling products VpCI 325 Water displacing Canola Oil Based Creates a tenacious film Protects for 2 yrs. indoors Can be used by spraying, dipping or atomizing Worthington Steel currently uses this product VpCI 329D Water displacing Petroleum based Creates a film Protects for 2 yrs. indoors Emits chemistry into airspace Can be used by spraying, dipping or atomizing Ferrous Metal Processing and Stripco currently use this

7 Why Cortec is different Traditional oil based rust preventatives trap water onto the surface of the coil. Our unique chemistry fights for the metals surface, displaces the water and protects the coil. VpCI 325 and VPCI 329D actually push the water off of the surface of the coil and create a film to protect it from humidity and condensation.

8 When to apply After the pickling process is complete Final pass or last stand of cold rolling At the temper mill during tempering or rewinding of finished product Oil is applied at slitters, just prior to the recoiler

9 Oiling in the pickling process

10 A series of spray nozzles spray the oil prior to recoiling The spray can be done intermittently with a squeegee set up to spread the oil across the whole coil

11 Electro Static Oiler

12 Electro static oilers use an eletro-static atomization technique It offers better spraying and work reliability Reduces the amount of oil used Produces little pollution And provides better coverage 325 has been tested and approved in the use of these oilers.

16 Acid Carryover Sometimes customers will experience staining from acid carryover from the pickling process via airflow. This acid will travel from the pickling process and settle onto the coils. Typically this will cause a staining on the coils. Our products cannot prevent staining. This problem is typically due to air management and can be solved by contacting an air management company who specializes in this. Often times you will see that the staining did not occur under the strapping that is placed on the coil which will indicate the staining came after the coil was oiled. It can also indicate that it came from acid in the air which can be caused by bad airflow.

18 Wet Tempering Applications VpCI 344 Wet tempering is the process of reducing the gauge of the metal through a series of rollers. Traditionally mineral and other oils have been used to reduce friction, heat and provide corrosion protection. AK had tested 344 in their labs and found the corrosion protection to be outstanding and actually contacted Cortec to trial the product. AK steel tested 344 to replace mineral oils and had excellent results on cold rolled, galvanized and aluminized steel using 344. Although 344 was not implemented at AK due to old equipment issues. It did prove to be an excellent alternative. AK Steel is currently evaluating BioCorr as an option for this process.

19 BioCorr, 329D or VpCI 337 for Edge Spray For customers using a dry pickling process, they will run into issues with rust protection. Spraying 337 on the ID, OD and laps of the coils is an easy way to protect after this process. BioCorr or VPCI 329D can also be used in this process. Companies that aren t pickling and still need protection can use any of these three products which can be sprayed, are easy to process without clean up in the next stage and can also be wrapped in VpCI 126 packaging after it has dried if they will be shipped in questionable conditions such as an uncovered truck.

20 Edge Spraying with VpCI 337

21 VpCI 126 tubing Packaging coils can be difficult if the customer is using a bag. By using a tube, you can achieve complete enclosure when using strapping. With a C-Hook Hold coil in the air with C-hook. Pull tube over coil, past C-hook so material is on both sides. Tuck material into the ID of coil not being held by hook Lower coil and tuck the other end of tube into the ID The tube will meet in the ID of the coil and can be taped Lower coil down onto pallet and secure strapping

22 Packaging Coils in a VpCI tube

23 VpCI 126 tubing continued With a coil grab (eye to the sky) Place half of the tube over the pallet so the film forms at the bottom of the pallet and is out of the way. Half of the tube will be above the pallet and should be gathered so it can be placed into the center of the ID of the coil as it is being lowered. Once the coil is lowered, bring the bottom of the tube that has been placed around the pallet up over the OD of the coil and push through the ID at the top. The tube will meet in the center and can be taped or heat sealed, strapping can then be placed through the center of the ID.
