Ke kumu o ke kila kila

Ua hoʻokumu ʻo Brearley i ke kila kila i ka makahiki 1916 i loaʻa i ka palapala Pelekane a hoʻomaka i ka hana nui, a hiki i kēia manawa, ua kaulana ke kila kila i ka ʻōpala a puni ka honua, ʻike ʻia ʻo Henry Brearley ʻo "ka makua kāne o ke kila kila".I ka wā o ke Kaua Honua Mua, hoʻihoʻi mau ʻia nā pū Pelekāne ma ke kahua kaua i hope no ka mea ua luhi ke keʻena a hiki ʻole ke hoʻohana.Ua kauoha nā keʻena hana pūʻali koa i ka hoʻomohala ʻana i ke kila kila Breer Li e pale i ka ikaika kiʻekiʻe, ka loea i ka hoʻoponopono ʻana i ka pilikia o ka ʻaʻahu o ka lua.Ua hōʻiliʻili ʻo Brearley a me kāna mea kōkua i nā ʻano kila like ʻole i hana ʻia ma ka home a me nā ʻāina ʻē, nā ʻano waiwai like ʻole o ke kila kila, i nā ʻano mechanical like ʻole o nā hoʻokolohua hana, a laila koho i ke kila kūpono i nā pū.I kekahi lā, ua hoʻāʻo lākou i ke ʻano o ka hao hao kūloko i loaʻa ka nui o ka chromium.Ma hope o ka hoʻāʻo ʻana i ka pale ʻana, ua ʻike ʻia ʻaʻole hiki ke hoʻohana ʻia e hana i nā pū.No laila ua hoʻopaʻa lākou i nā hopena o ka hoʻokolohua a hoʻolei iā lākou i kahi kihi.I kekahi lā, i kekahi mau mahina ma hope mai, ua holo wikiwiki kekahi mea kōkua iā Brearley me kahi ʻāpana kila."E ka haku," wahi āna, "ua loaʻa iaʻu ka huila mai Mr. Mullah i koʻu hoʻomaʻemaʻe ʻana i ka hale waihona kālā."Maikaʻi loa!"Ua ʻōlelo ʻo Brearley me ka hauʻoli me ka nānā ʻana i ke kila ʻālohilohi.

Hōʻike nā hopena hoʻokolohua ʻaʻole makaʻu i ka waika, alkali, paʻakai kila kila.Ua hana ʻia ke kila kila e kekahi mullah Kelemania i ka makahiki 1912, akā ʻaʻole maopopo ka mullah no ke aha ia.

Ua noʻonoʻo ʻo Brearley: "E hiki anei ke hoʻohana ʻia kēia ʻano kila, ʻaʻole hiki ke hoʻohana ʻia no nā kīʻaha kīʻaha, ʻaʻole no nā pū?"Ua ʻōlelo ʻo ia i maloʻo maloʻo, hoʻomaka ʻo ia e hana i ka pahi huaʻai stainless steel, ka ʻōpala, ka puna, ka pā huaʻai a me ka pahi pelu.

I kēia manawa ʻoi aku ka nui o ka hoʻohana ʻana i ke kila kila, ke piʻi nei ka makemake, a laila ʻo ka mea aʻe e kamaʻilio e pili ana i ka hoʻokaʻawale ʻana a me ka hoʻohana ʻana i ke kila kila.

Hoʻopili nā metala a pau me ka oxygen i ka lewa e hana i kahi kiʻiʻoniʻoni oxide ma ka ʻili.ʻO ka mea pōʻino, hoʻomau ka oxidize i ka hao i hoʻokumu ʻia ma ke kila kalapona maʻamau, e ʻae ana i ka hoʻonui ʻana i ka ʻino a lilo i mau lua.Hiki ke hoʻopaʻa ʻia ka ʻili o ke kila kalapona e ka electroplating me ka pena a i ʻole nā ​​metala pale oxidization e like me ka zinc, nickel a me chromium, akā, e like me ka mea i ʻike ʻia, he kiʻi ʻoniʻoni wale nō kēia pale.Inā haʻihaʻi ka papa pale, hoʻomaka ke kila ma lalo e pala.

Kū'ē i ka ea, ka mahu, ka wai a me nā mea ʻeleʻele palupalu nāwaliwali a me ka waikawa, ka alkali, ka paʻakai a me nā mea ʻē aʻe corrosive medium corrosion o ke kila.ʻIke ʻia hoʻi ʻo ka ʻakika kuhiliʻole - ke kila kūpaʻa.Ma ka hoʻohana pono ʻana, kapa pinepine ʻia ke kila me ke kūpaʻa palupalu palupalu, a ʻo ke kila me ke kūpaʻa kino kemika ua kapa ʻia he kila kūpaʻa waikawa.Ma muli o ka ʻokoʻa o ka haku mele ʻana, ʻaʻole kū pono ka mea mua i ka corrosion medium, ʻoiai ʻo ka mea hope he pale maʻamau.ʻO ke kūpaʻa ʻino o ke kila kila 2 e pili ana i nā mea hoʻohui i loko o ke kila.ʻO Chromium ka mea kumu e hana ai i ka pale ʻana i ka ʻino.Ke hiki i ka chromium ma loko o ke kila ma kahi o 12%, chromium a me ka oxygen i loko o ka corrosive medium e hana i kahi kiʻiʻoniʻoni oxide (self-passivation film) ma luna o ke kila kila, hiki ke pale i ka corrosion hou o ka matrix kila.Ma waho aʻe o ka chromium, hoʻohana mau ʻia nā mea hoʻohui a me ka nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., e hoʻokō i nā koi o nā hoʻohana like ʻole o ka hoʻolālā kila kila a me ka hana.

ʻElua, hoʻokaʻawale ʻia ka hoʻokaʻawale ʻana o ke kila stainless steel i:

1. Ferritic kuhiliʻole kila.Chromium 12% ~ 30%.ʻO kona kūpaʻa ʻana i ka corrosion, ka paʻakikī a me ka weldability e hoʻonui me ka piʻi ʻana o ka ʻike chromium, a ʻoi aku ka maikaʻi o kona kūʻē ʻana i ka chloride stress corrosion ma mua o nā kila kila.
2. Austenitic kila kila.Loaʻa iā ia ma mua o 18% chromium, 8% nickel a me kahi liʻiliʻi o ka molybdenum, titanium, nitrogen a me nā mea ʻē aʻe.ʻO ka hana piha maikaʻi, hiki ke pale i ka corrosion o nā ʻano media like ʻole.
3. Austenitic ferrite duplex kila kila.Loaʻa iā ia nā pono o ka austenitic a me ka ferritic stainless steel, a he superplasticity.
4. Martensitic kila kila.Ka ikaika kiʻekiʻe, akā maikaʻi ʻole ka plasticity a me ka weldability.

ʻEkolu, nā ʻano a me ka hoʻohana ʻana i ke kila kila.

ʻEhā, kaʻina ʻili kila kuhiliʻole.

ʻElima, ʻo kēlā me kēia ʻano wili wili kila a me nā huahana hana nui.

ʻO nā hale wili kila ʻē aʻe: Shandong Taigang, Jiangyin Zhaoshun, Xinghua Dayan, Xiʻan Huaxin, Southwest, East steel specialized, hoʻohana nui kēia mau hale liʻiliʻi i ka hana ʻōpala e ʻōwili i ka pā, ke kaʻina hana hope, ka ʻokoʻa o ka pā, ʻaʻohe hōʻoia hana mechanical, element. ʻaneʻane like nā mea i loko o ka hale hana nui, ʻoi aku ka liʻiliʻi o ke kumukūʻai ma mua o ka hale hana nui me ke ʻano like.

ʻO nā wili kila i lawe ʻia: Shanghai Krupp, ʻApelika Hema, ʻAmelika ʻĀkau, Iapana, Pelekiuma, Finland, lawe ʻia mai ka papa hana ʻenehana holomua, maʻemaʻe a nani hoʻi ka papa papa, ʻoki ʻoki, ʻoi aku ke kumukūʻai ma mua o ke kumu hoʻohālike home.

ʻEono, ʻano hoʻohālikelike kila kila a me ka nui: ʻo ka pā kila kuhili ka leo a me ka leo pā mua:

1. Hoʻokaʻawale ʻia ka ʻōwili i loko o ka ʻōwili anu a me ka ʻōwili wela, ʻoki ʻia ka ʻōwili a me ka ʻōwili maka.
2. He 0.3-3mm ka mānoanoa o ka wili anuanu, aia he 4-6mm mānoanoa o ka pepa i ʻōwili ʻia, laula o 1m, 1219m, 1.5m, i hōʻike ʻia e 2B.
3. ʻO ka mānoanoa o ka leo ʻōwili wela ma ke ʻano he 3-14mm, aia ka leo 16mm, ākea ka 1250, 1500, 1800, 2000, me NO.1.
4. ʻO nā ʻōwili me ka laula o 1.5m, 1.8m a me 2.0m he mau ʻōwili lihi.
5. ʻO ka laulā o ka ʻōwili burr ma ke ʻano he 1520, 1530, 1550, 2200 a pēlā aku ka laulā ma mua o ka laulā maʻamau.
6. Ma ke kumu kūʻai, ʻokoʻa ke ʻano like o ka ʻōwili lihi ʻoki a me ka ʻōwili maka maka ma kahi o 300-500 yuan.
7. Hiki ke hoʻopaʻaʻia ka leo e like me ka lōʻihi o nā koi o ka mea kūʻai, ma hope o ka kapaʻiaʻana o ka mīkini wehe i ka papa hāmama.Cold rolling general opening 1m*2m, 1219*2438 is also called 4*8 feet, wela rolling general opening 1.5m*6m, 1.8m*6m, 2m*6m, e like me keia mau nui i kapaia ka papa ma'amau a i ole ka nui o ka nui.

Ua kapa ʻia ka pā mua i ka ʻōwili pepa hoʻokahi:

1. ʻO ka mānoanoa o ka papa kumu maʻamau maʻamau ma waena o 4mm-80mm, aia 100mm a me 120mm, hiki ke hoʻopaʻa ʻia kēia mānoanoa.
2. ʻO ka laula o 1.5m, 1.8m, 2m, lōʻihi ma mua o 6m.
3. Nā hiʻohiʻona: ʻO ka pā mua he nui ka leo, ke kumu kūʻai kiʻekiʻe, ka pickling paʻakikī a me ka lawe ʻole ʻana.

ʻEhiku, ʻokoʻa mānoanoa:

1. No ka mea, o ka mīkini wili kila i loko o ke kaʻina olokaʻa, ua wela ka owili deformation liʻiliʻi, e hopena i ka mānoanoa o ka olokaa mai o ka papa deviation, maʻamau mānoanoa ma waena a lahilahi ma na aoao elua.Ke ana i ka mānoanoa o ka papa, e ana ka moku'āina i ka hapa waena o ke poʻo o ka papa.
2. Hoʻokaʻawale ʻia nā ʻae ʻana i nā tolerances nui a me nā tolerances liʻiliʻi e like me ke koi o ka mākeke a me ka mea kūʻai aku.

ʻEwalu, ʻo ka hapa o kēlā me kēia mea kila kila:

1. 304, 304L, 304J1, 321, 201, 202 umekaumaha kiko 7.93.
2. 316, 316L, 309S, 310S kaumaha kiko 7.98.
3. He 7.75 ka mahele o ka moo 400.
