I roto i te maimoatanga wera o te whakamaarama, na te nui o te mana o te oumu whakawera me te wa whakamahana roa, he nui te kaha o te whakapau kaha i roto i te mahi katoa, i roto i te waa roa, me pehea te whakaora i te kaha i roto i te maimoatanga wera o te whakamaarama he raru uaua.

Ko te mea e kiia ana ko te "kore insulation" te whakamahana, ko te tohu ki te whakamahana whakawera, tona mata me te matua kia tae ki te whakamahana whakamahana whakawera, kaore he whakamaarama, ka tinei tonu te whakamahana. E ai ki te ariā austenitic tuku iho, me roa te wa whakamahana i roto i te whakamahana, kia oti ai te whakamaarama me te tipu o te hauhautanga, te toenga me te tipu o te hauhautanga. homogenization o austenitic.Ko te hangarau tinei me te whakawera o te hanga i raro i te arata'iraa o tenei theory.Compared 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 production tōtika o te 20%-30, engari ka taea e te oxidation te whakaiti i te kaha o te 20%-30. decarbonization, deformation me te pera i runga i, e he pai ki te whakapai ake o te kounga hua.

I te wa e wera ana te waro waro me te rino koranu iti ki te Ac1, ki te Ac2 ranei, ka tere ake te tukanga homogenization o te austenite me te whakakorenga o nga carbide i roto i te pearlite. I te wa e uru ana te rahi o te maitai ki te waahanga angiangi, kaore te tatauranga o te wa whakawera e whai whakaaro ki te whakamahana waiariki, ara, ki te whakatutuki i te kore o te waiariki tinei. whakawera i roto i te oumu rangi, te pāmahana o te mata me te matua kua tata tae i te wa ano, na e taea te waiho tona wa ōrite, whakaritea ki te tukanga whakaputa tuku iho (r=aD) ki te whakarea whakawera nui, ka taea te whakaiti i te 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 insulation" 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 te "kore insulation" tukanga e taea te whakarite i nga āhuatanga miihini o nga whakaritenga; te whakamahana "whakawera atu i te whakamahana tuku iho ka taea te whakaora i te wa whakawera mo te 50%, 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 "kore insulation" ki te whakakore i te witi, te whakapai ake i te kaha.
