Kore te tiaki i te wera, te tinei me te whakatikatika i nga whao

I roto i te maimoatanga wera o te whakamaarama, na te nui o te mana o te oumu whakawera me te wa whakamaarama roa, he nui te paunga o te kaha i roto i nga mahi katoa, i roto i te waa roa, me pehea te whakaora i te kaha i roto i te maimoatanga wera o te whaa. he raruraru uaua.

Ko te mea e kiia nei ko te "kore insulation" tinei, ko te ki te tohu ki te whakawera forging, tona mata me te matua ki te tae ki te tineia pāmahana whakawera, kahore he mahanga, tonu tinei tukanga meangiti.E ai ki te ariā austenitic tuku iho, me whai te forging he roa. te wa whakawera i roto i te tukanga whakawera, kia rite ki te whakaoti i te nucleation me te tupu o austenitic witi, te rewa o te toenga cementite me te homogenization o austenitic.Ko te hangarau tinei me te whakawera o forgings i whakaputaina i raro i te arata'iraa o tenei ariā.Whakaritea ki te tukanga tinei o nāianei, "kore wera tiaki" tinei e whakaora i te wa o te tiaki wera e hiahiatia ana e te homogenization o te hanganga austenitic, e kore anake e taea te whakaora 20% -30% o te pūngao, te whakapai ake i te pai production 20% -30%, engari ano e taea te whakaiti te whakakore ranei i nga ngoikoretanga o te waikura, te whakaheke warowaiha, te whakarereke me etahi atu, e pai ana ki te whakapai ake i te kounga o te hua.

te kopa, te kopa paipa, te kopa miro, ko te paraharaha, ko te tira maitai, ko te kopa porotītaha, ko te kopa ki runga, ko nga paraka hangai, ko te kopa o te kaki, ko te kopa hono, ko te kopa orifice, ko te kopa mo te hoko, ko te pae porowhita, ko te papa a tawhio noa, ko te kopa hono, ko nga paipa paipa. , kakai kaki, kopa hono

A, no te waro waro maitai me te iti koranu maitai e wera ki Ac1 Ac2 ranei, te tukanga homogenization o austenite me te rewa o carbide i roto i te pearlite he tere ake. Ina no te rahi maitai ki te awhe wahi kikokore, te tātaitanga o te wa whakawera e kore e hiahia ki te whakaaro. te whakamahana waiariki, ara, ki te whakatutuki i te kore o te whakamaarama waiariki tinei.Hei tauira, i te mea ko te diameter, te matotoru ranei o te 45 nga mea mahi maitai kaore e neke ake i te 100mm, te whakamahana i roto i te oumu hau, te pāmahana o te mata me te matua kua tata ki te i te wa ano, na reira ka taea te warewarehia tona wa rite, ka whakatauritea ki te tikanga whakaputa tuku iho (r=aD) me te whakarea whakawera nui, ka taea te whakaheke tata ki te 20%-25% te wa whakawera tinei.

Ko te tātaritanga ariā me nga hua whakamatautau e whakaatu ana ka taea ki te tango i te "kore whakawera" i roto i te tinei me te whakawera whakawera o te maitai hanganga. Ina koa, 45, 45 mn2 waro hanganga maitai ranei huānga kotahi koranu maitai hanganga maitai, te whakamahi o "kore marara" Ka taea e te tukanga te whakarite i nga ahuatanga miihini o nga whakaritenga; 45, 35CrMo, GCrl5 me etahi atu waahanga mahi maitai, ko te whakamahinga o te whakamahana "kore insulation" atu i te whakamahana tuku iho ka taea te whakaora i te wa whakawera mo te 50%, te katoa o nga penapena hiko o 10% - 15%, te whakapai ake i te pai o te 20% -30%, i te wa ano "kore insulation" tukanga tinei e tauturu ki te whakamahine witi, te whakapai ake i te kaha.
