tube drawing
1.EXPERIMENTS CONCERNING AND APPLICATION OF RUSSIAN TYPE DIES FOR STEEL TUBE COLD-DRAWING
3.Φ38 mm×6. 6 mm seamless tube of steel TP347H (1Cr19Ni11Nb) was produced at Taiyuan Steel by hot metal pretreatment + 30 t EAF melting alloying steel - 75 t K-OBM-S blowing - VOD treatment - LF - bloom by 5. 6 t ingot or 220 mm×220 mm concasting billet -Φ100 mm tube blank piercing - cold rolling ( cold drawing) flow sheet.
7.The paper details the advanced techniques and process facilities employed by some representative American tube-rolling mills such as the Diescher mill and cold-drawing mill in Plymouth Tube Co. , the PPM-MPM mill in Fairfield Works, U.S. Steel as well as the MPM mill in North Star Steel Co. .
9.TUST-SHC tube paper package structure design software is developed based on AutoCAD2000, using DCL language to develop the dialog box interface, using AutoLISP language to develop the drivers of dialog box and the drawing program, using the InstallShield6.22 to make the setup program from the compiled program module.
