| Abstract: | In order to remedy the often-occurred outflow-splashing shortage of the 650 mm undersize head room,the effects of vacuum degree,flow rate of argon,vacuum keeping time on the vacuum degassing are analyzed on the basis of vacuum degassing thermodynamics and dynamics.An efficient variable vacuum pump system was matched eventually.After detailed debugging,the operating regulation of vacuum system,argon blowing and refining process were optimized.The production results indicate that 210 t VD furnace in Xinyu Iro... |
