Abstract:For the problems such as the poor alloying ability, the large heat dissipation of the induction body and the easy blockage of the molten groove in the line-frequency channeled induction melting-copper furnace，the optimizing retrofit such as expanding the spacing between the molten groove, enhancing the thermal insulation of the induction body and adjusting to the aspect ratio of the trench cross-section has been completed. The application indicates that after the trench spacing increases by 90mm, the temperature difference between the melt inlet and outlet will increase by 9.1℃, the melt outlet speed increase by 0.042 m/s, the element-dispersion performance be improved, the element particles become smaller, and the improvement on the melt-alloying ability of the induction furnace is proved, and after the aspect ratio of the trench cross-section is adjusted from 1.31 to 1.04, the blockage failure of the molten trench by the metal with the high melting point and the big size will be eliminated, and after the nano-micropore plate with the thickness 10mm and the murlite insulating brick with the thickness 32mm is added to the insulation structure of the induction body, the temperature of the steel shell will drop by 179℃ and the electricity consumption reduce by 52 kW.h/t. It will help to move the process of 30.60 double carbon target in the recycled brass melting and casting industry forward.
