Powder Metallurgy Structural Mbali
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.
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.
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.
