Abstract:
Cu-11Ni-2W alloys have been prepared by vacuum non-consumable arc-melting and high-frequency induction melting injection moulding. The effects of melting processes on the resultant microstructure were studied. The results show that the grain of Cu-11Ni-2W alloy prepared by vacuum non-consumable arc-melting is coarse and the microstructure includes α solid solution and W particles. As for the sample prepared by high-frequency induction melting injection moulding, the grain is superfine and the microstructure is α solid solution. Moreover, the thermal conductivity coefficient for the sample prep

Abstract:
23Co-Ni is an ultra-high strength steel and it needs ultra low nitrogen content in the steel. The removal of nitrogen for 23Co-Ni steel in a 6t/12t Vacuum Induction Melting Furnace (VIM) with different melting processes was studied. The results show that, the longer of the melting time and the higher of the vacuum level, the lower of the final nitrogen contents is. The denitrogenization rate can reach 70% when the melting time is more than 8 hours. The electromagnetic stirring can increase the denitrogenization speed. When the VIM is vacuumed to 1-3 Pa, it can make the nitrogen content reaches

The discussion of temperature control includes a review of proportional controllers and heat-regulating devices. Integration of control functions is illustrated with examples related to heating of steel slabs, surface hardening of steel parts, vacuum induction melting for casting operations, and process optimization for electric-demand control. Distributed control within larger manufacturing systems is discussed. The chapter also covers nondestructive techniques for process control and methods for process simulation.
