Rolling Process

The rolling process reheats the billets produced in the steelmaking process and then produce them to create products of the size and shape desired by the customer. Currently, DaehanSteel has an annual capacity of 1.55 M tons (1.1 M tons of deformed rebar and 450,000 tons of coiled rebar).

Step 1
Reheating Furnace

This reheats the billets transferred from steelmaking. It is a heating process aimed at stretching the billets to the desired thickness and length. DaehanSteel's heating furnace operates in an eco-friendly manner using SCR (Selective Catalytic Reduction), a technology that removes nitrogen oxides from exhaust gases.

Step 2
Rolling

The billet extracted from the heating furnace is shaped into rebar by passing it through upto 22 stands (rolls), which are divided into rough rolling, intermediate rolling, and finishing rolling. 6m long billets are produced, yielding up to 1.4 km of rebar (D10 standard). DaehanSteel continues to develop technology and invest in facilities to produce high-quality rebar.

Step 3
Cooling Stand and Coiling

The cooling stand cools the products that have passed through the rolling line. The products are transported to the cutter using the Walking Beam method while being exposed to cold air from all directions.

This is the equipment process step in which products rolled with a Vertical Compact Coiler are transformed into coils.

Step 4
Cutting (Straight Rebar)

Products from the cooling stand undergo strict quality tests, are cut to the customer's desired lengths, and are packaged in bundles using automated equipment. They are then identified by a color change on the rebar's cross-section based on type before being sent to the customer.

Step 5
Inspection and Packaging

Cut straight rebar and coiled rebar are banded after passing strict quality tests and inspections, then sent to customers with a product description tag attached.
