South Korean company Daehan Steel Co., Ltd. has awarded SMS group an order covering the completion of the rebar rolling mill in its Pyeongtaek plant.
The new equipment will allow Daehan to bundle rebars in small and main packages. Starting material will be billets 130 and/or 150 millimeters square with a length of 12 meters in low and medium carbon grades. The throughput rate will be 70 tons per hour. The rebars having a diameter range from 10 to 32 millimeters will be bundled to packages of commercial lengths from six to 12 meters and will have a weight between 1.5 to 2.5 tons. For products D10 to D19, the packages will have a weight of 400 kilograms.
The rolling mill features an EBROS billet welding system, 14 HL (Housingless) mill stands and an eight-pass finishing block with VCC® (Vertical Compact Coiler) to produce five-ton coils of the rebar product sizes mentioned above.
The scope of supply includes a new crop and dividing shear, a new cooling bed fitted with HSD® (High Speed Delivery) system, a newly designed cold-cutting system acting with counting stations, equipment for bundling small and main packages and for tying to ensure the packages will have a stable shape. The plant will feature latest SMS group technology for high-speed bar mills and tying equipment, such as
- HSD® (High Speed Delivery) system which stands for increased productivity and maximum yield at high speeds of up to 35 meters per second.
- Fully automated tying machines with energy consumption reduced by about 50 percent compared to the old-design compactors.
Established in 1954 as Daehan Trading, the company was mainly active as a wire rod producer and in the 1970s started to produce steel bars due to a rapid growth of the Korean economy.
Over the years, the company became a specialized steel producer. In 1992, it changed its name to Daehan Steel and emerged as one of the most important steel producers in the Far Eastern countries. With the present investment Daehan Steel will expand its possibilities on the local market and in the neighboring countries.
Commissioning of the facilities is scheduled for mid-2020. Once in operation, the plant will be one of the most advanced and productive benchmark for the markets in terms of technology, quality, efficiency and low operational costs.
