No ke aha e paʻakikī ai ka hana ʻana i nā mea Stainless Steel?

ʻO ke kila kila,  i kapa mua ʻia he kila rustless, ʻo ia kekahi o nā hui ferrous alloys i loaʻa ka liʻiliʻi ma kahi o 11% chromium, kahi mea hana e pale ai i ka hao mai ka ʻele a hāʻawi pū i nā waiwai pale wela.

Ke hoʻohālikelike ʻia me nā metala "ʻoluʻolu" e like me ke aluminika, paʻakikī loa ke kila kila i ka mīkini. ʻO kēia no ka mea ʻo ke kila kuhili ʻole he kila kila me ka ikaika kiʻekiʻe a me ka plasticity maikaʻi. I ke kaʻina hana mīkini, e paʻakikī ka mea a hoʻoulu i ka wela. ʻO kēia ke alakaʻi ʻana i ka ʻoki wikiwiki ʻana i ka mea hana. Eia nā kumu nui 6:

1. ʻO ka ikaika wela kiʻekiʻe a me ka hana paʻakikī

Ke hoʻohālikelike ʻia me ke kila maʻamau, ʻoi aku ka ikaika a me ka paʻakikī. Eia nō naʻe, aia ka nui o nā mea e like me Cr, Ni, a me Mn, a loaʻa ka plasticity maikaʻi a me ka paʻakikī, ka ikaika wela kiʻekiʻe, a me ka manaʻo paʻakikī hana kiʻekiʻe e hopena i ka ukana ʻoki. Eia kekahi, i ka austenitic stainless steel i ka wā o ka ʻoki ʻana, ua hoʻoheheʻe ʻia kekahi carbide i loko, kahi e hoʻonui ai i ka hopena scratching ma ka mea ʻoki.

2.Pono ʻoki ʻoki nui

ʻO ke kila kila ka nui o ka plastic deformation i ka wā e ʻoki ai, ʻoi aku ka austenitic stainless steel (ʻoi aku ka elongation ma mua o 1.5 mau manawa ma mua o 45 kila), kahi e hoʻonui ai i ka ikaika ʻoki.

He mea maʻamau ka 3.Chip a me ka mea paʻa paʻa

He mea maʻalahi ka hana ʻana i ka ʻaoʻao i kūkulu ʻia i ka wā e ʻoki ai, e pili ana i ka ʻili o ka ʻili o ka ʻili i hana ʻia a maʻalahi ka ʻili o ka ʻili o ka mea hana.

4. He mea maʻalahi ka puʻupuʻu e wili a haki

No nā mea ʻoki ʻoki paʻa a semi-pani ʻia, ua maʻalahi ka hana ʻana o ka puʻupuʻu puʻupuʻu, ka hopena o ka hoʻonui ʻia ʻana o ka ʻili a me ka ʻoki ʻana i nā mea hana.

Fig.2. ʻO ke ʻano chip maikaʻi o ke kila kila

5. ʻO ka helu nui o ka hoʻonui laina

ʻO ia ma kahi o hoʻokahi a me ka hapa ka nui o ka hoʻonui laina laina o ke kila kalapona. Ma lalo o ka hana o ka ʻoki ʻana i ka mahana, hiki i ka mea hana ke hoʻololi i ka thermal deformation a pili i ka pololei dimensional.

6. Ka liʻiliʻi i ka wela

ʻO ka maʻamau, ʻo ia ma kahi o 1/4 ~ 1/2 o ka conductivity thermal o ke kila kalapona waena. He kiʻekiʻe ka wela o ka ʻoki ʻana a ʻaʻahu wikiwiki ka mea hana.

Pehea e hana ai i ke kila kila?

Ma muli o kā mākou hana a me kā mākou ʻike, ke manaʻoʻiʻo nei mākou e hahai ʻia nā alakaʻi e pili ana i ka mīkini ʻenehana stainless steel:

1.Hoʻomaʻamaʻa wela ma mua o ka hana ʻana, hiki i ke kaʻina hana wela ke hoʻololi i ka paʻakikī o ke kila kila, e maʻalahi ai ka mīkini.

2.Excellent lubrication, hiki i ka wai lubricating hoʻoluʻu ke lawe i ka nui o ka wela a lubricate i ka ʻili o ka huahana i ka manawa like. Hoʻohana maʻamau mākou i ka lubricant hui ʻia i haku ʻia me ka nitrogen tetrafluoride a me ka ʻaila ʻenekini. Ua hōʻoia ka hoʻomaʻamaʻa ʻana he kūpono loa kēia lubricant no ka mīkini ʻana i nā ʻāpana kila kila me nā ʻili laulima.

3. E hoʻohana i nā mea hana ʻoki kiʻekiʻe e loaʻa i nā ʻāpana ʻāpana ʻoluʻolu a me nā ʻae liʻiliʻi ʻoiai e hōʻemi ana i ka manawa hoʻololi mea hana.

4.Lower oki wikiwiki. ʻO ke koho ʻana i ka wikiwiki ʻoki haʻahaʻa hiki ke hōʻemi i ka hana wela a maʻalahi i ka haki ʻana.

Ka hopena

ʻO nā mea āpau, ʻo ke kila kila kekahi o nā mea paʻakikī loa i ka mīkini. Inā hiki i ka hale kūʻai mīkini ke hana maikaʻi loa i ka aluminika, ke keleawe, a me ke kila kalapona, ʻaʻole ia he manaʻo hiki iā lākou ke mīkini maikaʻi loa.
