Dangjin plant equipped with a fully automated facilities that can improve high precision and quality, is producing hot rolled products that are used in various application such as structural, electronics, building materials, high-pressure gas containers and pipelines.
Manufacture Process
STEP 01
Scarfing
Slab:removing the surface scale by jetting high pressure water
STEP 02
Reheating Furnace
Heating uniformly the slabe to be the optimal rolling temperature(1,200~1,250℃) to the direction of thickness, width and length
STEP 03
Sizing Press
Located in exit position of heating furnace to press to the level of customer order
STEP 04
Roughing Mill
Making bar to the thickness relavant to finishing mill 정
STEP 05
Coil Box
Winding the bar suffering roughing mill to the form of coil, maintaining the temperature (900~1150℃) uniformly to diminish the temperature and materials variation of the Top and End of the bar parts
STEP 06
Edge Heater
Located in the middle of coil box and Crop Shear, heating the edge part locally to diminish width direction temperature variation
STEP 07
Crop Shear
Top of Slab, cutting Tail error parts randomly
STEP 08
Finishing Mill
Rolling with the thickness and width according to customer order
AGC(Automatic Gauge Control) :thickness control system
STEP 09
Run-Out Table
After finishing mill, water-cooling to the aimed temperature in the process of passing through cooling process controlling mechanical properties by adjusting cooling rate and patterns
STEP 10
Down Coiler
Making in the form of coil by winding the strip that passes cooling process in mandrel
