Ko te tukatuka tukatuka kirihou i roto i te whakarewa.

1. Tuhinga o mua Te whakawera kirihou tere

Te korero noa, I te wa e tarai ana te whakawera, te tere tere Te whakawera kirihou tere, Ko te nui o te ahotea wera i hangaia i roto i te ー500 °C konumohe konumohe, tera pea e raru ai te whakarereke me te ngau i te maara. Ina koa mo te kowiri maitai, te kowiri tira, Na te ngoikore o te waiariki, Me tupato nga tohu motuhake. Wera, Mo etahi ahua uaua o nga puranga teitei, He mea tika kia kaha te tango i nga waahanga e pai ake ana.

Heoi, I roto i nga keehi takitahi, Te whakawera tere i etahi wa ka iti te whakarereke. I tenei wa, ko te mata anake o te hangai ka wera, Na kei te toe tonu te pokapū “kōpeke”, Na, ko te ahotea hanganga me te ahotea wera e tino whakaitihia ana, Na he nui te kaha o te ātete matua, Na reira ka whakaiti i te huringa o te kukume. E ai ki etahi wheako wheketere, it is used to solve There is a certain effect on the hole pitch deformation.

2. Tuhinga o mua plastic heating temperature

The quenching heating temperature affects the hardenability of the material, and at the same time affects the composition and grain size of austenite.

1) From the perspective of hardenability, high heating temperature will increase the thermal stress, but at the same time increase the hardenability, so the structure stress also increases, and gradually dominates. Hei tauira, carbon tool steels T8, T10, T12, etc., when quenched at general quenching temperature, the inner diameter shows a tendency to shrink, but if the quenching temperature is increased to ≥850°C, the hardenability increases and the structural stress gradually becomes dominant Status, so the inner diameter may show a tendency to bulge.

2) Mai i te tirohanga o te hanganga Austenite, Ko te piki ake o te pāmahana quanchina te whakanui ake i te kaupapa Austenite, me te tapawha o te Martensite i muri i te tihorea (nui ake te rahi), Ko wai te whakanui i te rōrahi i muri i te kukume.

3) Mai i te tirohanga o te awe o te mana o te MS, Mena he tiketike te pāmahana queenching, Ko nga purapura Austenite ka tino rite, ka whakapiki ake i te huringa me te hiahia o te hiahia o nga waahanga.

Hei whakarāpopototanga, Mo nga tohu maitai katoa, Ina koa ko etahi waahanga nui-waro me te rahi o te aorangi, Ko te pāmahana quanching e tino pa ana ki te huringa o te kukume o te kirihou ー500 °C konumohe konumohe, Na ko te kowhiringa tika o te pāmahana whakawera umu he mea nui.

Te korero noa, Ko te whiriwhiri i te tino kaha o te pāmahana whakawera i te mutunga kaore i te pai mo te whakarereke. I raro i te kaupapa kaore i te pa ki te mahi, Ko te pāmahana whakawera kirihou o raro ka whakamahia tonu. Heoi, Mo etahi tohu kowiri me te Austenite tonu i muri i te kukume (penei i te cr12mov, etc.), Ko te nui o te Austenite tonu ka taea te whakatika ma te whakatika i te pāmahana whakawera hei whakatika i te huringa o te whakarewa.

3. Te mana o te reiti makariri

I te nuinga, Ko te whakapiki i te reeti whakamahana i runga ake i te tohu MS ka nui ake te ahotea o te ahotea, Na i te mutunga, Ko te huringa i puta mai i te ahotea wera ka piki ake te piki; Te whakanui ake i te reiti whakamarumaru i raro i te tohu MS ka nui ake te rereketanga o te taumahatanga o te kiko. Nui. Ki

Mo nga momo tohu maitai rereke, Na te mea he rereke nga taumata o nga tohu MS, A, no te mea ka whakamahia taua reo quanching, He rereke nga mate rereke. Mo te akomanga maitai taua, Mena he rereke nga panui quanching, He rereke ano hoki nga hiahia o te huringa korero mo o raatau kaha o te hauhautanga.

Hei tauira, Ko te tohu MS o te kowiri waro he iti noa iho, Na, ka whakamahia te whakamahana wai, Ko te mana o te ahotea wera e kaha ana ki te kaha; Ahakoa ka whakamahia te whakamahana, Ka kaha ake te ahotea hanganga.

I roto i te hanga tūturu, Ko te nuinga o te wa kaore e tino whakahekehia te aukati i te wa e whakawhiwhia ana ratou, kua oti te whakawhiwhi, ki te whiu ranei, na ko te ahotea wera te nuinga o te paanga, e hiahia ana ki te whakaheke i te ana. Heoi, Na te mea kaore i te tino nui te ahotea wera i tenei wa, Na reira, He iti noa te katoa o te huringa. Mena ka taea te whakamahi i te kume-wai-wai-hinu, te tiihi hinu ranei, Ko te ahotea wera i nui ake, Na ka piki te parekura.

4. Te awe o te pāmahana

Ko te hua o te pāmahana makariri i runga i te huringa ko te nuinga i puta mai i te hurihanga o te hanganga i te waa o te mahi whakamataku. Mena te ahuatanga o “quanching tuarua” ka puta i te wa o te mahi whakamataku, Ko te Austenite pupuri ka hurihia hei marttensite, Na ko te mea nui o te Marttensite i hangaia he nui ake i te kaupapa pumau, Ko wai ka puta i te ana o te anara ki te whakawhānui; Mo etahi taputapu taputapu teitei-roa, penei i te cr12mov, Ka whakamahia te quenching pāmahana nui ki te hiahia kia pakeke te whero hei kaupapa matua. Ka maha nga maha, Ko te rōrahi e whakawhānui ana i nga wa katoa ka mahia te riri. Ki

Mena he mea whakatoia ki etahi atu rohe o te pāmahana, Ko te rōrahi e whakahekehia ana e te hurihanga o te martensite ki te martensite (ranei te ruinga pāmahana, kaiwhakamarie mohio, etc.), Na ka kaha te heke o te ana.

Hei taapiri, Ko te whakangahau o te taumahatanga toenga i roto i te whakatipu i te wa e pa ana ki te riri. I muri i te tiihi, Mena kei te ahua o te awangawanga te mata, ka nui te rahi o te riri; i te anga ke, Mena kei te ahua o te awangawanga te mata, Ka puta te heke.

Engari ko nga paanga e rua o te hurihanga o te whakariterite me te whakangahau i te ahotea, Ko te mua ko te mea nui. Ko te mea i runga ake nei ko te tātaritanga o nga momo ahuatanga o te huringa o te hangai mai i te maimoatanga wera, ka taea noa te whakamahi hei tohutoro hei whakaoti i te raru.
