Tube extrusion press line for stainless grades
The 50-MN tube extrusion press line installed in Changwon in South Korea has an annual capacity of 35,000 tons of tubes in diameters between two and ten inches in Fe and Ni-based austenitic steels, duplex and super-duplex alloys as well as special steels made of nickel-based alloys. With the inauguration of the plant taking place less than 24 months after contract signing, the team of SeAH and SMS group specialists has succeeded in sticking to the extremely tight project schedule.
Within the scope of the contract, SMS group supplied a multi-stage IAS induction heating plant, a vertical 20-MN piercing press, a 50-MN extrusion press and the run-out facilities. The pusher-type two-strand horizontal induction heating plant with integrated temperature equalization chambers processes billets of 204 to 380 millimeters in diameter. The billets are reheated in the four-station vertical induction heating plant before being prepared in the piercing and expansion press for the process in the tube press. After a three-station final heating process, the billets are transferred to the tube press. The run-out facilities with quench and cooling table are designed for extrusion lengths of up to 22 meters. SMS group also supplied associated ancillary equipment such as glass lubrication systems, manipulation and auxiliary equipment and a machine for making glass pads.
With SMS group we had a perfect partner by our side, capable of offering the complete process chain - from reheating down to the finished tube - from a single source. We are very proud that our new line could be started up so early.
