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 whakamahana i roto i te tukanga whakamahana, kia oti ai te whakamaarama me te tipu o nga karepe austenitic, te whakakorenga o te toenga cementite me te homogenization o austenitic.Ko te hangarau tinei me te whakawera o te whakamahana o te hanga 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 Ka taea e koe te whakaora i te 20% -30% o te kaha, te whakapai ake i te pai o te whakaputa 20% -30%, engari ka taea hoki te whakaiti, te whakakore ranei i nga hapa o te waikura, decarbonization, deformation me te pera i runga i, e he pai ki te whakapai ake o te kounga hua.

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. ko te whakamaarama waiariki, ara, ki te whakatutuki i te kore whakamaarama waiariki tinei.Hei tauira, ka kore e neke ake i te 100mm te diameter, te matotoru ranei o te 45 mea mahi maitai, te whakamahana i roto i te oumu rangi, ka tata te pawera o te mata me te uho i te wa kotahi, na reira ka kore e arohia tona wa rite, ka whakatauritea ki te tikanga whakaputa tuku iho (r=aD) me te whakarea whakawera nui, ka taea te whakaheke ma te tata 20% -25% tinei wa whakawera.

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 mea hanga maitai, te whakamahi i te "kore te whakamahana "whakawera atu i te whakamahana tuku iho ka taea te whakaora i te wa whakawera mo te 50%, ko te katoa o nga penapena hiko o te 10% -15%, te whakapai ake i te pai o te 20% -30%, i te wa ano ka awhina te tukanga tinei "kore" ki te whakamahine. witi, whakapai ake i te kaha.
