Abstract
The main distinctive feature of plasma-arc remelting with formation of an ingot in a cooled copper mould is the ability to treat liquid metal with gas. Remelting in a gaseous medium containing nitrogen, allows doping with nitrogen directly from the gas phase. The high efficiency of nitrogen doping from the gas phase during plasma-arc remelting is shown on the example of remelting chromium-manganese steel Kh21G17AN2, sparsely alloyed by nickel, and some peculiarities of such technology are given. Ref. 9, Table. 2, Fig. 3.
