The slab from the continuous casting mill or the bottom mill is heated in the reheating furnace at a temperature of 1,250¨¬C. After the slab is heated and before it can be rolled, the scale that has accumulated on the slab¡¯s surface is removed by the scale breaker. At the roughing mill and finishing mill, the slab is rolled to its target specifications before being cooled at the cooling table where it is then made into hot rolled coils.
General structural steel and welding structural steel are used in the construction of steel structures, bridges, ships and automobiles.
This type of steel enhances in both corrosion and atmospheric corrosion resistant properties, adding such special elements as P, Cu, and C, and is used in the manufacturing of containers, special automobiles and construction structures.
This high-strength steel has a good weldability and is used in automobile frames, members, and wheel disks.
This steel, excellent in weldability and formability, is widely used in structural pipes, general pipes, special pipes, and machine structural carbon steel pipe.
This steel, which have high strength and good formability, is used in high-pressure gas container with less than a 500l inner capacity containing LPG, acetylene and other high-pressure gases.
This type of steel is characterized by a strict quality of high strength, extremely low temperature toughness, excellent weldability and fracture resistance, and is used in drilling and producing in severely cold areas, or for deep sea oilwells.
This steel excels in high strength, extremely low temperature toughness, hydrogen induced crack resistance and weldability, and is thus used in line pipes.
This steel includes general machine structural steel, alloy steel and steel for tools and used for various machine parts.
This steel is used to manufacture cold rolled steel, galvanized steel and electro galvanized and color steel sheet.
This steel has received approval for its manufacturing process from overseas classification societies. A, B, and D grade products are used in shipbuilding and are excellent in weldability and shock resistance.
Carbon tool and spring steel are produced to be used in such special applications as saws, washers, tapelines and springs that require good hardenability and fatigue resistance.
