WHAKAPIRIPIRINGA maitai - te tukanga me tona whakaahuatanga. Carburizing maitai i te kāinga

Ano carburizing maitai ko te tukanga e hāngai ana e te i runga i te tukatuka matū-waiariki. Ngā Ko tōna ngako i roto i te whakatinanatanga o te waiwai o te mata tūringiringi o mea rauemi he nui rawaka o te waro, ka wera ki te taiao etahi.

Carburizing maitai. Ko te whakaaro o tenei mahi

Ko te whāinga matua o tenei tukanga ko ki te whakahaere haamaitairaa o te kahu o runga o te mihini me te āhuatanga nui e tika ana o te waro, te ōrau o e ai i roto i tenei take e 0.8-1.1%. Ka rite ki te hua o te mahi taua whiwhi te i muri i tinei o te taumata tiketike o te pakeke o te rauemi, i te mau tonu tona matua kirihou te. Tenei taonga nui o te tukanga.

momo

E ai ki te tohu o te kaha o te matua o te mātauranga e wehea ki toru ngā rōpū matua o te rauemi tukatuka:

• Ki te neuprochnyaemoy matua. I roto i tenei rōpū ngā timahia taua rama steels waro, rite 10, 15, 20. Whakamahia ratou i roto i te taipitopito ki te rahi iti me mahi malootvetstvennymi. Here, te paparanga timahia i roto i te whakahaere i pakeke huringa austenite ki te ranunga ferritic-pearlitic.
• Ki te matua, whakaū ngoikore. Ko te rōpū ngā chromium iti koranu maitai rama pērā i 15X, 20X. He pupuri doping atu e tāpiritanga iti o te vanadium hua te witi maitai, e hua i roto i te pai ake te ukanga me te taikaha o te rauemi.
• Ki te matua tino hardenable. Steels o tenei rōpū e whakamahia i roto i te hanga o nga wahi, i whai he wāhanga ripeka nui te whirihoranga matatini ranei, a ka wheako hoki e whai wāhi nui pānga ru ranei kawenga ki taurangi ahotea nui. kawe ratou nika fakahoko (12Kh2N4A, 12HNZA, 20HN). No te mea o te matekai o te rauemi e ētahi wā kawea atu tona whakakapinga i te konupora, whakamahia ki te nui tāuru iti o te vanadium Titanium ranei ki te kia mongamonga witi.

Fele whakamahia carburizing te ki te hanga i tētahi ōrau nui o te pakeke mata o nga wahi, me te ki te whakatutuki i mauroa tiketike, i hanga nei e te tono maimoatanga wera i muri i whakahaere i te tukanga.

He aha e nga taipitopito o tenei tauwhitinga e ngohengohe ki

Kei te whakamahia Carburizing maitai mo te hua e whai ake nei:

- nihowhiti ;

- "maihao";

- ngahaú;

- toki;

- huanga;

- "noke";

- wāhanga whanau (mowhiti mōmona me topenga), me ētahi atu.

Methods mō te carburizing

Ki te mea i reira e rave rahi ngā momo o tenei rauemi, ia o ratou kua ka tono ona tikanga ake o tenei tukanga. Ko te tikanga, kia hua ai timahia maitai i raro i ngā āhuatanga rerekē me ngā taiao, me te whakahauanga pāmahana o 850 ki te 950 degrees. Na reira, a faaite i te maha o ngā tikanga o te mahi:

1. Tukanga carburizing tupu i roto i te carburizer mārō. I roto i tenei take, ko te reira taea ki te whakamahi i ngā rauemi organic (wheua kararehe, rakau, me ētahi atu) me te pararopi (Coke) i roto i te taha ki te ngā activators. ka puta te haamaitairaa o te waro i roto i te tauhohe matū o te piti hāora. Ko te whakamahi o activators i roto i tenei take whai wāhi ki te pai, me te tere te tauhohenga. Ko tino whai hua mō te whakatutuki i nui hohonu carburizing tenei tikanga. Ko reira whai hua i roto i te hanga o te maitai Tuhinga hua kōwae. Heoi, i tenei tukanga ko e kai ana wa rawa, e titau te reira i te whakapaunga nui o te pūngao, te wā me te pūngao.

2. Ko te tukanga o te carburizing puta i raro i te mana o hau. Ko te noa ki te whakamahi i hau e whai take (māori, kātua, me ētahi atu). ranei kāwai o e mangere (hauota) tenei tikanga. tei katoa i runga i te takitahi. Haunga carburising hau e hāngai ana-maitai hangaia te ki te ōrau iti o tīmeka kukū waiwaro, pōwaro waiwaro tahi ranei. Nuinga o ngā wā, e whakamahia ana i tēnei tikanga i roto i te hanga nui-tauine, engari he tino utu nui i roto i ngā o te moni. whakamahia te tikanga rite te i roto i te hanga waiariki. I roto i te wera oumu, rotortnuyu ranunga e whakahaeretia o organic pūhui rāpoi tiketike (hei tauira, oki, Ethyl waipiro, me ētahi atu), e, i roto i te tahuri, i te kaha ki te hinga i raro i te mana o kaiwhakakökï (nika).

3. Ko te carburization tukanga wai. Kei te whakamahia te reira i roto i te cyanide me bestsianidnyh pati. āhuatanga Ia o enei taiao e ona ake āhuatanga, huapai me ngā huakore. Hei tauira, e kore e cyanide pati whakarōpūtia rite kinokore. Kei te nuinga o whakarōpūtia ratou rite mōrearea mō te pāpāho taiao e kore anake te taiao, engari ano hoki mo te tangata. Na reira, ka whakamahi i taua rauemi e tamata ki te whai i mehua haumaru tikanga katoa ki te karo i hopearaa kino. Otiia e kore e te tūtohu te tikanga e hāngai ana i runga i te pati bestsianidnoy ki te tono tika ki te meka e arata'i te reira ki contamination tina heke o te taiao, me te mahi kino nui. Ēnei tikanga ki te e whakamahia ratou i roto i te mahi, he reira anake tika mo te pāpaku rire carburizing.

maimoatanga Heat o ngā hua timahia

He taipitopito tino nui tukatuka hoki tenei tukanga. I muri i te katoa, ara i muri i cementing te hua e kore e whai i te ōrau nui o mauroa me te tika. Na reira, ko te taahiraa whakamutunga i roto i tenei take ko te mahi o te pakeke, me te tempering. Tinei tukanga kua he maha o ngā āhuatanga me ngā āhuatanga. e te tukanga katoa wahi i raro i te mana o te tupu WHAKAPIRIPIRINGA witi, a ka hoki ai ki runga ki te wāhanga ripeka he kākahu-kore, me te te pau kāore. Na reira, ko te ora ake tinei e rave rahi ngā wāhanga, ia o nei puta i roto i etahi tikanga pāmahana.

mutunga

I muri te tai'oraa i te runga ake, ka taea e tatou te mea e ko te tino nui te whakahaere o tenei tukanga i roto i te hanga o ngā hua maitai. Tenei mahi tino whakakaha i te wahi apa mata. A, no te matou nga pūkenga motuhake i roto i tenei rohe, me nga rauemi e tika ana, me te taputapu e taea te kawea i roto i carburizing maitai i roto i te kāinga.
