Click on each step for a detailed description.

01.

Coil Build Up

Leader Strip is welded both sides of hot coil, examining surface and dimension of material to reduce non rolling part, when performing cold rolling.

02.

Coil Grinding

Sutface is ground with grind belt to produce high end product(BA and MR) and to eliminate defect on coil surface occurred during working hours prior to cold rolling.

03.

Coil Rolling

lt is specially designed rolling mill for products requiring high strength and precisinon, such as stainless steel plate. lt is used to roll hot coil, with tension on both reel.

04.

Annealing & Pickling

lt is process to give unique surface of stainless steel by eliminating scale on surface and covering with passivity layer while heat treatment recovers modified internal structure of stainless steel occurred during cold rolling.

05.

Bright Annealing

Modified internal structure of stainless steel occurred during cold rolling is recovered by heat treatment under oxygen free atmosphere. lt is divide by degreasing and heat treatment.

06.

Skin Pass

lt is process to roll heat treated stainless plate with load and tension in order to improve form and give gloss.

07.

Tension Levelling

Modified form through cold molding and heat treatment is leveled by strong tension to give flatness.

08.

Coil Polishing

Coil Polishing & Finish Polishing

Surface of stainless steel is rolled by sandpaper which rotates at high speed to achieve desired illumination on surface. lt is used to produce finishing #4, HL prodeusts.

09.

Brushing Machine

Surface of stainless steel is rolled by sandpaper which rotates at high speed to obtain #8 products which have glossy surface.

10.

Sheating

Cold rolling material which processed at previous process is cut in necessary length.

11.

Slitting

Cold rolling material whuich processed at previous process is coated with protective vinyl and cut in ordered length.
