Hāʻawi ʻia e H angao i ka ʻenehana ka ʻenehana anneal ed me ka maʻemaʻe o loko a me waho o ka ʻili, pololei ka hoʻomanawanui ʻana, ka ikaika kiʻekiʻe, ke kūpaʻa corrosion ikaika a pēlā aku.Pehea e loaʻa ai kēlā paipu?
Hoʻohana nui ʻia ʻo Austenitic stainless steel i nā ʻano hana kīwila, ʻoihana a me nā pūʻali koa.Loaʻa iā lākou i nā ʻano huahana like ʻole, e like me nā kī, nā koʻokoʻo, nā ʻāpana, nā ʻāpana, nā paʻi, nā foil, nā paipu, nā paipu, nā mea pono, nā flanges a me nā mea hana ʻē aʻe.
Inā hoʻomaʻamaʻa ʻia ke kila kuhili ʻole i loko o ka umu maʻamau, ʻo ka mea chromium i loko o ka austenitic stainless steel e hana me ka oxygen i ka lewa e hana i kahi ʻāpana ʻokikene hina, i kapa ʻia ʻo 'scale', pono e hoʻoneʻe ʻia e ka hana pickling.
Hiki i ka ʻoluʻolu annealing mālamalama ke hoʻoikaika i kēia kaʻina hana.I mea e mālama ai i kahi hiʻohiʻona maikaʻi, mālama i ka luster metala maoli a pale i ka pickling, pono e hoʻomālamalama ʻia ke kila kuhili ʻole austenitic i hoʻopaʻa ʻia i loko o ka pale a i ʻole ka momi e pale ai i ka wehe ʻana o ka ʻili.Hiki ke hoʻopili ʻia nā māka a pau o ka austenitic stainless steel.Hiki i ka lewa pale ke hydrogen maʻemaʻe, ka amonia i hoʻokaʻawale ʻia, a i ʻole i kekahi manawa ma ka momi.ʻAʻole ke kinoea pale i ka hoʻoheheʻe ʻia o nā huahana austenitic stainless i ka wā annealing.
No laila, loaʻa nā pōmaikaʻi o ka solution annealing bright:
1, ʻaʻole hoʻemi wale ka annealing i ka paʻakikī o ka paipu kila, hoʻomaikaʻi i ka ductility, hoʻomaikaʻi i ka plasticity, akā maʻalahi hoʻi e ʻoki a me ke anuanu deformation.
2, hoʻomaikaʻi i ka pale ʻana i ka corrosion ma ka hoʻopau ʻana i ka ua carbide intergranular, i nani ka helehelena.ʻO ka hoʻomaʻemaʻe ʻana i ka palaoa a me ka hoʻolālā kila like ʻole a me ka hoʻohui ʻana, hoʻomaikaʻi i nā waiwai kila, akā hoʻomākaukau hoʻi no ka mālama wela.
3, hoʻopau i ke koena o ke koʻikoʻi kūloko i ke kila, pale i ka deformation a me ka haki.
4. Oxidation a me ka decarbonization i ka wā wela a me ka hoʻoluʻu i ka maʻamau annealing, no laila, ua hoʻomaʻamaʻa ʻia ke kila wela, e hoʻonui ai i ka poho a me ke kumukūʻai o ka metala.
5. ʻaʻole e loaʻa i ka oxidation mālamalama, maikaʻi ka pale ʻana i ka corrosion.No ka mea, ʻo ka annealing ʻālohilohi ka mālama wela o ke kila kila i loko o ka lewa palekana o ka hui ʻana o ka hydrogen a me ka nitrogen, loaʻa ka ʻili me ka ʻole o ka oxidation ma ka hoʻomalu pono ʻana i ke kinoea pale i loko o ka umu.Ke hoʻohālikelike ʻia me ka ʻili i loaʻa e ka annealing maʻamau a me ka pickling, no ka mea ʻaʻohe kaʻina oxidation, ua hoʻemi ʻia ka chromium deficiency phenomenon ma luna o ka ʻili, a ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion ma hope o ka polishing.
6. lapaʻau ʻālohilohi e mālama i ka pau ʻana o ka ʻili o ka ʻōwili, ʻaʻole hiki ke hana hou ʻia a loaʻa i kahi ʻālohilohi.Ma muli o ka annealing ʻālohilohi, paʻa ka ʻili o ka paipu i ka luster metala mua, ua loaʻa i ka ʻili kukui, ma lalo o nā koi maʻamau, hiki ke hoʻohana pololei ʻia me ka ʻole o ka hana ʻana i kona ʻili.
7.ʻAʻohe pilikia haumia ma muli o ke ʻano pickling maʻamau.ʻAʻole pono Annealed ka paipu i ka pickling a i ʻole ka lāʻau like, mai hoʻohana i ka waikawa, ʻaʻohe pilikia pollution ma muli o ka pickling.
No laila pehea mākou i hiki ai i laila?
On-Line Fixing & Fusing (Anealing) mea hiki ke wela i ke kila kuhiliʻole welded pipeto 1050 ° C a laila e hoʻomaha ia i ka mahana ma lalo o 100 ° C ma lalo o ka pale o ka hydrogen. ʻO ka mana hoʻomehana o ka induction ferquency intermediate ka DSP hou loa. + ʻO ka hoʻolālā IGBT. Me ka DSP digital control system, aia nā hana hoʻomalu pilikino a me nā hana diagnostic ponoʻī. hiki i ke kila ke ho'ōla i ka ikehu 15% -20% i ka hoʻohālikelike ʻana i nā huahana ʻē aʻe o ka papa like. Ke hoʻohana nei i ka hydrongen e like me ke kinoea i kēlā me kēia minuke.
