Heat-ātete maitai turboproizvodstve. āhuatanga Main o te rauemi

timata Heat steels ātete me alloys rite te momo motuhake o ngā rauemi hanga ki te whakamahi rawa ngā i roto i te hononga ki te whanaketanga o te ahumahi mīhini huri hiko hanga. Mīhini huri hiko hei puna pūngao transducer ranei whakamahia i roto i te taputapu mana waiariki, rererangi me te kaipuke engines. Āhua tata te tini o te hau mīhini huri hiko hoahoa mō te whenua okeoke kararehe (taraka, locomotives).

Ki te hua i roto i te pāmahana hau kokoru iti te kohi wahie motuhake ia te mana wae. I roto i tenei whakaaro, i roto i te wā tika poto o te wā i reira nga maitai wera-ātete. I teie mahana, e ki runga, ki te 50% o te taimaha katoa enei rauemi i roto i whakaaro mīhini huri hiko.

Heat whakakeke maitai ko te rauemi mahi e kore anake i pāmahana teitei. Ko reira hāngai i roto i te āhua i te huru slozhnonapryazhennogo mo te wā wā tomu'a. Ko te āhuatanga tuatahi e whakatau te mahi o te rauemi mea he nui-pāmahana te kaha.

I raro i tenei kounga e kore e matau i te take ārahi ki te whakangaromanga o te ahotea deformation homai i te mea nehenehe o te tautoko i te rauemi whakarewa i roto i te hoahoa ngā i te pāmahana i homai mo te wā wā motuhake. A, no te te wā ka whakaritea, me te ngaohiko, te āhuatanga kaha kurut huaina (-wā roa). Ki te mea i whakaritea deformation, wa me te ahotea, huaina te kounga ko kaha ngokingoki.

steels Heat-ātete i, haunga te kaha, te kānapanapa, e me tonu ra ano te mutunga o te mahi. I roto i ngā o rāhui plasticity e tata tika o te whakarewa mahi.

Ko te āhuatanga nui o te rauemi he kakari tūtohutanga. takoto ana tēnei kounga e i roto i te puka o whanaunga pahure wa tae noa ki te kore o ngā tauira maeneene me te kāniwha whakamatautauria i te taumahatanga pāmahana taua. Heat steels ātete whakaaro kakari kiriuka i te ōwehenga rite ki nui atu kotahitanga ranei.

Nā ki te meka e te ara ki te pāmahana whakahaere puta i runga i te wā, ai hāngai te mahi ki te timatanga, te tikanga he pāmahana ambient, utua he aro nui te ki te uara o te elasticity me te kaha. He mea nui i tiketike nui uara puritia e te rauemi i te pāmahana rūma.

Nā ki te meka e slozhnonapryazhennogo whakahaeretia nga steels wera ātete i raro i te huru āhuatanga nei i te huringa tamau i roto i te tohu, me te nui o te kawenga, kahore mahu'inga me te ātete rohirohi tiketike.

I teie mahana te whakamahi o rongoā hangarau uaua mo te hanganga o ngā hanganga necessitates whai rauemi whakarewa he āhuatanga hangarau tiketike. Ko te kupu, i roto i te hanga o te matatahi i roto i engines hau mīhini huri hiko whakamahia rikarika ki, pū rikarika ki, te oro, tikanga tukatuka mīhini a oti tuhinga rakau, hanga pū te whakarewanga, orooro. mahi Production o nga ruma ngingiha o pepa whakarewa wera-ātete te whakamahi i te kiato, matao hanga, wahi fehokotaki'anga me ētahi atu hangarau. Kei te kakano ia nga tikanga tino noa kawehiko te waku tūringiringi te honohono, brazing hua. enei whawhe katoa rapu āhuatanga kounga teitei o te rauemi e whakamahia ana.

Superalloys me maitai ere ahei o te pupuri nui haere tohu kaha rite ki nga kaimahi, me te ki te tukatuka pāmahana. Tenei, i roto i te tahuri, haamau te tohu motuhake i runga i katoa te hangarau whakarewa tohatoha anō whakamahia, ki te deformation o te Ingot me mua ki te whakahaeretanga o mutunga whakamutunga, hua ki te whakapati mata e hiahiatia ana me ngā āhuatanga e hiahiatia ana.
