Kupsinjika kupsinjika kumatsitsa zoperewera

Kuchepetsa Kupanikizika imagwiritsidwa ntchito pazitsulo zopangidwa ndi zitsulo zopitilira muyeso komanso zopanda mafuta ndipo cholinga chake ndi kuchotsa kupsinjika kotsalira kwamkati komwe kumapangidwa ndi njira zopangira kale monga makina, kuzizira kozizira ndi kuwotcherera. Popanda izi, kukonzanso pambuyo pake kumatha kubweretsa kusokonekera kosavomerezeka ndipo / kapena zinthuzo zitha kudwala chifukwa cha zovuta zakumunda. Chithandizochi sichiyenera kupanga kusintha kwakukulu pazinthu zakuthupi kapena makina, motero nthawi zambiri chimangokhala kutentha pang'ono.

Ma steels a kaboni ndi ma aloyi amatha kupatsidwa mitundu iwiri yopumulira kupsinjika:

1. Chithandizo pamtundu wa 150-200 ° C chimachepetsa kupsinjika kwakumapeto kowumitsa popanda kuchepetsa kwambiri kuuma (mwachitsanzo, zinthu zolimba, zotengera, ndi zina zambiri)

2. Chithandizo chake makamaka pa 600-680 ° C (mwachitsanzo, atawotcherera, kusinthana ndi zina zambiri) kumapereka mpumulo wa nkhawa.

Kupsinjika kutulutsa mipata yazitsulo ya kaboni pamtunda wa 30 mapazi / 9.1 mita pamphindi kuti muchepetse kuuma kuchokera panja 2 ”/ 51mm mbali iliyonse kuti athetse zovuta zomwe zimadza kumapeto
Zakuthupi: Mpweya zitsulo zopindika (5.7-10.2 ”/ 145-259mm mulifupi ndi 0.07-0.1” /1.8-2.5mm wakuda)
Kutentha: 1200 ºF (649 ºC)
Nthawi zambiri: 30 kHz
Zida Zotenthetsera Induction: HLQ 200kW 10-30 kHz makina otenthetsera okhala ndi malo otentha akutali okhala ndi 10 μF capacitors
- Makina angapo otsekemera otsekemera omwe amapangika ndikupangidwira izi
Njira Zapamwamba zazitsulo za Carbon zimadutsa koyilo yolowetsa pamtunda wa 30 mapazi / 9.1 mita pamphindi kukwiya kapena kupsinjika kutulutsa chitsulo cha kaboni. Munthawi imeneyi, chitsulo cha kaboni chimatentha mpaka 1200 ºF (649 ºC). Izi zikhala zokwanira kuchotsa kuumitsa ntchito kuchokera ku 2 "/ 51mm mbali iliyonse ya m'lifupi.

Zotsatira / Zopindulitsa

Kuthamanga: Kutulutsa mwachangu kumawotcha chitsulo cha kaboni kutentha, komwe kumathandizira kuthamanga kwa mphindi 30 pamphindi
-Kuchita: Kutentha Kwambiri Sikuti imangopulumutsa nthawi yopanga, imaperekanso ndalama zamagetsi
-Fointprint: Kuchulukitsa kumatenga gawo locheperako, chifukwa chake imatha kuchitidwa mosavuta popanga zinthu monga

Chithandizo pamtundu wa 150-200 ° C chimachepetsa kupsinjika kwakumapeto kowumitsa popanda kuchepetsa kwambiri kuuma (mwachitsanzo, zinthu zolimba, zotengera, ndi zina zambiri):

-Chithandizo chake nthawi zambiri ndi 600-680 ° C (mwachitsanzo, atawotcherera, kugunda Machining etc.)

-Ma alloys osakhala achitsulo amakhala opanikizika chifukwa cha kutentha kosiyanasiyana kokhudzana ndi mtundu wa aloyi ndi momwe zimakhalira. Ma alloys omwe akhala olimbikira zaka amangolekezera kupsinjika komwe kumachepetsa kutentha kotsika kutentha.

Zitsulo zosapanga dzimbiri za ku Austenitic zimachepetsa kupsinjika pansi pa 480 ° C kapena kupitilira 900 ° C, kutentha pakati pakuchepetsa kukana kwa dzimbiri m'masukulu omwe sanakhazikike kapena otsika kaboni. Mankhwala opitilira 900 ° C nthawi zambiri amakhala othandizira kuthana ndi mavuto.

Kukhazikitsa Kwa ena, koma osati onse, ma uinjiniya, kuyerekezera kumatha kufewetsa, kuumitsa kapena kupsinjika, kutengera zinthu, kutengera momwe zimakhalira poyamba. Cholinga cha mankhwalawa ndikuthana ndi zovuta zam'mbuyomu, monga kuponyera, kulipira kapena kugubuduza, pokonzanso zomwe sizili yunifolomu zomwe zimapangitsa kusakhazikika / mawonekedwe kapena, mwazinthu zina zamalonda, zimakwaniritsa zofunikira zomaliza zamakina.

Cholinga choyambirira ndikukhazikitsa chitsulo kuti, chitatha kupangika, chinthu chimayankha mokhutiritsa ku ntchito yolimba (mwachitsanzo, kukhazikika kwazithunzi). Normalizing imakhala ndi Kutentha chitsulo choyenera kutentha makamaka pamtundu wa 830-950 ° C (pamwambapa kapena pamwamba pa kutentha kolimba kwa ma steels olimba, kapena pamwambapa kutentha kwa carburising kwa ma carburising steels) kenako ndikuzizira m'mlengalenga. Kutentha kumachitika nthawi zambiri mumlengalenga, chifukwa chake makina osanjikiza kapena kumaliza pamwamba amafunika kuti achotse magawo osanjikiza.

Zitsulo zolimbitsira mpweya (mwachitsanzo zida zina zamagalimoto) nthawi zambiri zimakhala "zopsa mtima" (mopitilira muyeso) pambuyo pofiyira bwino kapangidwe kake ndi / kapena kulimbikitsa kugwiranagwirana. Zambiri zapa ndege zimafunikiranso kuphatikiza mankhwalawa. Zitsulo zomwe sizimakhazikika nthawi zambiri ndizomwe zimatha kuuma kwambiri pakuzizira kwa mpweya (mwachitsanzo zida zambiri zamagetsi), kapena zomwe sizipindula kapena kupanga zinthu zosayenera kapena makina amiyeso (monga maudzu osapanga dzimbiri).
