SeAH Changwon commissions extrusion press line

SeAH Changwon Integrated Special Steel (SeAH CSS) in South Korea has commissioned the tube extrusion press line which SMS group supplied in a record time. 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 duplex and super duplex alloys as well as Fe and Ni-based austenitic steels and special steels made of nickel-based alloys. The inauguration of the plant will take place less than 24 months after contract signing.

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.
