发明名称 METHOD FOR ACTING UPON MELT METAL BY MAGNETIC-PULSE FIELD AND APPARATUS FOR PERFORMING THE SAME
摘要 FIELD: changing physical structure of aluminum alloys by process different from heat treatment or deformation, namely by magnetic pulse field, possibly in metallurgical or machine engineering industry branches. ^ SUBSTANCE: method of acting of electromagnetic irradiation upon melt metal comprises steps of treating aluminum base melt by means of electromagnetic oscillations due to creating inside melt unipolar electromagnetic current pulses with duration 150 - 180 mcs and with power up to 5 kV. Apparatus for acting upon melt metal by means of electromagnetic irradiation includes submersible inductor in the form of multi-turn helix coated with layer of Al2O3. Turns of helix are fixed by casting inductor into magnetically transparent ceramic housing; said housing is made of composition containing marshalite, melt glass and water. ^ EFFECT: enhanced efficiency of acting upon melt metal, lowered cost of apparatus, reduced power consumption, possibility of operation at high temperatures. ^ 3 cl, 1 dwg
