Heat lapaʻau o ke kila - he nui metala? Iecaianoaaiiuo kaʻina

Heat lapaʻau o ke kila - ia mea he nui hao oka a manufacturing kaʻina hana, a kokua i ka hoʻoikaika 'ana i ko lakou pono waiwai. I kēia lā, i kēia hana ua hoʻohana 'ia e hoohuli i ke ano maoli loa metala nā huahana o.

Heat lapaʻau o steels komo ai pahuhopu nei manaʻo o nā kahua o ka hoʻonaʻauao ekolu:

1. Paio hahana maoli nō ka hao oka a no ka makemake ana wela.
2. Waiū lilo no manawa.
3. Anuanu.

He aha ka hana a hiki i ka hao oka a me na mea i ka hana?

Heat lapaau ninoieo o na kēia mau kapuwai.

1. Annealing. Kēia kaʻina ua ka hapanui hoʻohana no ka reflux, ape a forging. Kēia ke kaʻina hana no ka pono e emi i ka paakiki a me ka ho'ēmi i na aʻo nui i i hanaia i loko o ka welded huahana. Eia hou kekahi, annealing ua hoʻohana 'ia no ka makaukau o ka metala' ole i ka thermal pou-hana maikaʻiʻole i loko o ka aoao maoli i ka mea e hoʻoikaika 'ana i kona heterogeneity. Ma keia hana i komo wela ana kila 45, 45H, 40XC, 40XH a me nā kaha hao oka a pau.

2. Normalization. Kēia kaʻina hana i kekahi, mai ka mua kaʻina hana, i ke ano o ka hooholo ana o ka anuanu pae. Ka hope mua ua lawe mai ma hope paʻa ana māhele. Mau noonoo ana ua uku a hiki i ka hoʻoholo ma mua ana wela. Ma keia hihia i ke kila ua loaa me ka haʻahaʻa akā, kiekie ae paakiki. Ka 'ole o kēia mau huahana ie-na hua liilii. Penei, normalization lilo pono e paʻipaʻi i ka haku mele 'ana o ka weld, a no ka loaa i ka makemake hoʻonohonohoʻia.

3. hoopaakiki ana. Kēia ka anu u ua pili i ka aaioee o ke kila, ua hoʻohana 'ia no ka forgings, ka hoike ana, forgings a me na hapa malamaia lakou ma ka paʻi pepa i mea e mahuahua ikaika, paakiki, ka popopo ia'ku, e mae wale ia'ku, a me kekahi mau' ano. Kēia kaʻina komo ai hahana maoli nō kēia i ka hao oka a pau a hiki i ka wela ma luna o loko o kona hookahi loli paha. Extract me na termopokazatele kila, a me ka mahope anuanu maila 'ua lawe mai ana i ka mämä holo iki kiʻekiʻe. No keia mea loa pinepine hoʻohana NaOH koʻana koko paʻakai pāʻoihana, mea kāhinu, e like me ka ea. Ke'ōlelo mai, no ka kekahi laʻana, wela iapaau ana o kila 40X ma keia kahua, ua lawe mai i loko o ka aila. Muli o kona kulana pohihihi nui nui māhele e hoopaakiki ana i loko o ka wai hahai koke aku ma ka haʻahaʻa kala. Pinepine i nā huahana o keia momoku ahi hao oka a hele i kēia anu u ma ka paio hahana maoli nō i ke kiʻekiʻe-alapine (frequency) paialewa. I ka hopena o ke kiʻekiʻe paa ili.

4. haʻalele. Kēia kaʻina hana ninoieo ma ka paio hahana maoli nō ka naʻau o ke kila i ka kekahi ana wela. Next, ka mea hiki ke hooheheeia waiū hele, a me ka huʻihuʻiʻana. Ka hope mua ua lawe mai ana i ka lewa.

5. kūnewa. He anu u ninoieo i ka malama ana me ka hao oka a me ka metastable 'ole no ka lōʻihi manawa. Mahana E ole e lalo mehana ea. Kēia kaʻina hana e leie aku i ka mea hiki ke hooheheeia 'ole hapa' ia 'hoʻoneʻe i loko o ka oi paa ana ma ka hoololi ana i kā lākou me mechanical, a physical waiwai.

6. anuanu lapaau. Kēia mua o ka hoomau o ka kinai anuanu maila ', i i kaulia ana ma ka mehana ea. Ke anakahi no ka mea hiki ke hooheheeia mea,ʻaʻole he pilikiaʻilikai.

Noi hao oka a

Mai kila wela ana i ke kaʻina hana hiki me ka nui loa hoʻoikaika i nā 'ano o nā māhele i mai o ka hao oka a pau o kekahi ahi, ia mea ma ka nui koi i loko o nā wahi o ka hana. Mea i koe i ka hana 'enekinia, mokulele e kukulu, pahu-hale,? Iecaianoaaiiie o ka pōhaku puna huahana. Products, wela-ka hana maikaʻi, Hiki ke hoʻohana 'ma lalo loa hōʻeuʻeu e haawe a me kamakawiwo ole. Eia hou, e hoʻohana hao oka a pau i loko o ka hana o skyscrapers, nā hale hana a me na alahaka.
