Nā hiʻohiʻona o ka mīkini ʻoki plasma

Hiki i ka mīkini ʻoki plasma ke ʻoki i nā ʻano metala āpau i paʻakikī ke ʻoki ʻia e ka ʻoki oxygen me nā kinoea hana like ʻole, ʻoi aku ka maikaʻi o nā metala non-ferrous (stainless steel, carbon steel, aluminum, copper, titanium, nickel) ʻoi aku ka maikaʻi o ka hopena ʻoki;

ʻO kāna mea nui, ʻo ka ʻoki ʻana ʻaʻole no nā metala nui, wikiwiki ka wikiwiki o ka ʻoki ʻana i ka plasma, ʻoi aku ka maikaʻi o ka ʻoki ʻana i nā ʻāpana kila kalapona maʻamau, hiki i ka wikiwiki ke piʻi i ka 5-6 mau manawa o ke ʻano o ka ʻoki ʻana i ka oxygen, maʻemaʻe ka ʻoki ʻoki. liʻiliʻi ka deformation thermal, a ʻaneʻane ʻaʻohe wahi wela.

Ua hoʻomohala ʻia ka mīkini ʻokiʻoki plasma a hiki i kēia manawa, a ʻo ke kinoea hana hiki ke hoʻohana ʻia (ʻo ke kinoea hana ke ʻano conductive o ka plasma arc a me ka mea lawe wela, a ʻo ka metala i hoʻoheheʻe ʻia i ka incision pono e hoʻokaʻawale ʻia i ka manawa like) Loaʻa ka mana nui i nā hiʻohiʻona ʻokiʻoki, ka ʻoki ʻana i ka maikaʻi a me ka wikiwiki o ka arc plasma. loaʻa ka hopena ʻike. ʻO nā kinoea hana plasma arc maʻamau ka argon, hydrogen, nitrogen, oxygen, air, water vapor a me kekahi mau kinoea hui.

Hoʻohana nui ʻia nā mīkini ʻoki plasma i nā ʻoihana like ʻole e like me nā kaʻa, nā locomotives, nā moku kaomi, nā mīkini kemika, ʻoihana nuklea, nā mīkini maʻamau, nā mīkini hana, a me nā hale kila.

ʻO ke ʻano o ke kaʻina hana o nā lako plasma: ua hana ʻia kahi arc ma waena o ka nozzle (anode) a me ka electrode (cathode) i loko o ka pū, i hoʻokaʻawale ʻia ka wai ma waena, i mea e hoʻokō ai i ke kūlana o ka plasma. I kēia manawa, hoʻokuʻu ʻia ka mahu ionized i waho o ka nozzle ma ke ʻano o ka jet plasma e ke kaomi i hana ʻia i loko, a ʻo kona mahana ma kahi o 8 000 ° C. Ma kēiaʻano, hiki keʻokiʻokiʻia, welded, welded a me nāʻano'ē aʻe o ka wela wela.
