Abstract:
For its appearance, its electrical, mechanical and thermal
characteristics, as well as its stability, it is found that using a DCMF
re-constriction plasma arc and cutting along the major axis of its
cross-section is able to effectively improve cut quality, process
stability and cutting productivity. Given in this paper are the results
from the cutting tests on 16～20mm 1Cr18Ni9Ti plates, also given are
discussions on the structures of DCMF magnetic head, the physical
features and technological characteristics of DCME re-constriction
plasma arc, and on the choise of cutting parameters and the uniqueness
of cut quality.
