Kufotokozera Kwachidule:

Izi zimakhudzana ndi gawo lapadera lazitsulo zamafuta, chifukwa kachulukidwe, porosity, zida ndi njira zothetsera kutentha kwa magalasi azitsulo zimakhudza makamaka kuuma ndi mphamvu. Zida, kulimba kwambiri. Njira zochiritsira kutentha zimaphatikizapo kuzimitsa carburizing, carbonitriding, kuzimitsa kwapafupipafupi, kuzimitsa kwapafupipafupi, kuzimitsa mafuta, ndi zina.

Zogulitsa

Chifukwa cha magwiridwe antchito komanso mtengo wotsika wazitsulo zopangira zitsulo, magawo azitsulo amagwiritsidwa ntchito mochulukira mgalimoto, kuphatikiza zida zoyambira, chiwongolero, pisitoni ndi mpando wamagetsi wotsika pagalimoto yamagalimoto; Dongosolo la mabuleki lili ndi sensa ya ABS, mabuleki ananyema ndi zina zotero; Zida zama Pump makamaka pampu yamafuta, mpope wamafuta ndi pampu yotumizira m'magawo ofunikira; Injiniyo ili ndi ngalande, mphete ya mpando, ndodo yolumikizira, mpando wokhala ndi zida, zigawo zikuluzikulu zamagetsi osinthira nthawi ya valavu (VVT) ndi utsi kuthandizira chitoliro, ndi zina zotere.

I. Kukula kwa magawo azitsulo zamafuta a ufa

Ndi kukula mwachangu kwa mafakitale aku China zamagalimoto, msika wamagalimoto wagwiritsanso ntchito mwachangu.Mu 2015, China yotulutsa magalimoto idafika mayunitsi 24.5033 miliyoni, poyambira padziko lonse lapansi. Makampani opanga zida zamagalimoto aku China akwaniritsa ndalama zogulitsa za 3.23 trilioni yuan, pafupifupi pafupifupi 10% kuyambira chaka chatha.Ku mbali inayi, China italowa mgulu lazamalonda padziko lonse lapansi, sikuti amangopanga gulu lonse lamagalimoto akunja monga omwe amakhala, komanso zowerengera zazikulu zamafuta azitsulo, chilichonse chogulitsidwa, ndi makampani akunja omwe amagulitsa ndalama mdziko lathu, kuti apange mitundu yonse yazitsulo zamafuta zomwe zimapereka kuthekera kwakukula komwe kukufunika, kufunika kwakukulira pakukula kwa mabizinesi azitsulo aku China kwabweretsa mwayi wapadera.

Kuchokera pakuwona kwakutulutsa kwamtengo wamafuta azitsulo zamafuta, mtengo wogulitsa udakwera kuchokera ku 876.21 miliyoni yuan mu 2006 mpaka 367.826 miliyoni yuan mu 2015, ndikuwonjezeka kwapakati pachaka kwa 17.28%, ndikukhalabe ndi njira yopitilira kukula mwachangu , ndipo ufa wamafuta azitsulo zamafuta amafunikira pamsika amasungabe kukula kwakanthawi.

Kuuma kulamulira mankhwala onse ufa zitsulo pa kutentha mankhwala

Kuchuluka kwa ufa wamba wa atomized (kuphatikiza chitsulo cha kaboni ndi chitsulo cha kaboni-kaboni aloyi) ndiposa 6.9, ndipo kuuma kolimba kumatha kuyang'aniridwa mozungulira HRC30.

Mwambiri, kachulukidwe ka ufa wopangidwa kale (AB ufa) umapitilira 6.95, ndipo kuuma kolimba kumatha kuwongoleredwa mozungulira HRC35.

Maphala oyambitsidwa kale okhala ndi kachulukidwe kuposa 6.95 ndikuzimitsa kulimba komwe kumayendetsedwa ku HRC40.

Zitsulo zamagetsi zopangidwa ndi zinthu zomwe zili pamwambazi zimakhala ndizokhazikika komanso zakuthupi, ndipo kuuma pambuyo pochizira kutentha kumakwaniritsa zofunikira, kotero kulimba kwawo kwamphamvu ndi kuponderezana kudzafika pachimake.

Kodi kuuma kwa kutentha kwa ufa wachitsulo kungafikire zitsulo 45? Inde mutha!

Komabe, chifukwa kuchuluka kwa zinthu za PM sikokwanira kuposa nambala ya 45 yachitsulo, kuchuluka kwa zinthu zomwe zimakakamizidwa ndi PM nthawi zambiri kumakhala 7.2 g / cm, pomwe kuchuluka kwa No. 45 chitsulo ndi 7.9 g / cm. ufa wamafuta kapena kutentha kwapafupipafupi kuposa HRC45 kumapangitsa kuti mankhwala azitsulo azikhala olimba chifukwa chazimitsa kwambiri, zomwe zimapangitsa mphamvu yazitsulo zopangira ufa.

Kenako, tifananitsa zida zopangira P / M ndi zida zopangira zida.

1. Kugwiritsa ntchito kwambiri zinthu, mpaka kuposa 95%

2. Palibe kapena kudula pang'ono kumafunika

3. Kusasintha kwamitundu yolinganiza bwino, kukhazikika bwino komanso kulondola kwambiri.

4. Kuyerekeza kwamphamvu: akatswiri opanga ufa wamafuta adakulitsa kapangidwe kazitsulo zachitsulo, ndipo kulimba kwamphamvu ndi kupondereza kwamagiya opangidwa ndizoyandikira pafupi ndi zida zosinthira. Mwachitsanzo, zida zamagalimoto zamagalimoto zomwe zimafalitsa kwambiri Mphamvu zowoneka ngati ufa wamafuta ndizothandiza komanso zochulukirapo.

5. Ufa kukanikiza akamaumba ntchito akamaumba nkhungu, zingabweretse zina kudula luso hob hob sangabweretse akalumikidzidwa zovuta.

6. Chifukwa ndioyenera kupanga zambiri, kupanga bwino kwake kumakhala kwakukulu ndipo mtengo wake ndi wotsika kuposa kudula.

7. Yoyenera kupanga misa, motero mtengo wake ndiwampikisano kwambiri.
