Momwe mungasankhire ng'anjo yoyenera ya vacuum ya misa yotulutsa magawo

Chinthu chofunika kwambiri pa ntchito yotsika mtengo ya vacuum sintering ng'anjo ndikugwiritsa ntchito chuma cha gasi ndi mphamvu. Malinga ndi mitundu yosiyanasiyana ya gasi, zinthu ziwiri zamtengo wapatali za sintering zimatha kuwerengera 50% ya mtengo wonse. Pofuna kupulumutsa kugwiritsira ntchito gasi, njira yosinthira gasi yoyenda pang'onopang'ono iyenera kukhazikitsidwa kuti zitsimikizire kuti njira zochotsera mafuta ndi sintering sizikuipitsidwa. Pofuna kuchepetsa kugwiritsira ntchito mphamvu, zinthu zotenthetsera bwino zimagwiritsidwa ntchito popanga malo otentha kuti achepetse kutentha. Kuti muzindikire mfundo zamapangidwe awa ndikuwongolera mtengo wa R & D mkati mwanthawi yokwanira, ng'anjo yamakono yopulumutsira zida zopulumutsira idzagwiritsa ntchito zida zowerengera za hydrodynamic kuti mupeze mpweya wabwino kwambiri komanso mawonekedwe a kutentha.

Kugwiritsa ntchito mitundu yosiyanasiyana ya ng'anjo

Mosasamala kanthu za makina osinthika komanso apadera kwambiri, ng'anjo zambiri za sintering pamsika zitha kugawidwa m'ng'anjo yanthawi ndi nthawi komanso ng'anjo yopitilira mlengalenga. Magawo a bulauni akamaumba jekeseni komanso chothandizira / chotsitsa chimakhala ndi polima yotsalira. Mitundu yonse iwiri ya ng'anjo imapereka chiwembu chochotsa polima.

Kumbali imodzi, ndi koyenera kugwiritsa ntchito mokwanira ng'anjo yopitilira mumlengalenga ngati ili gawo lalikulu kwambiri lopanga misala yosasinthika kapena mawonekedwe ofanana. Pankhaniyi, ndi kuzungulira kwachidule komanso kuchuluka kwa sintering, mtengo wabwino wopindulitsa ukhoza kupezeka. Komabe, m'mizere yaying'ono ndi yaying'ono yopanga, ng'anjo yopitilira iyi imakhala ndi 150-200t pachaka, kukwera mtengo kolowera komanso voliyumu yayikulu sizopanda ndalama. Kuphatikiza apo, ng'anjo yopitilira mumlengalenga imafunikira nthawi yayitali yotseka pakukonza, zomwe zimachepetsa kusinthasintha kwa kupanga.

Kumbali inayi, ng'anjo ya periodic vacuum sintering ili ndi ukadaulo wapamwamba kwambiri wowongolera njira yochotsera sintering. Zolepheretsa zomwe tazitchula kale, kuphatikiza ma geometric deformation ndi kuwonongeka kwa mankhwala kwa magawo a MIM, zitha kuthetsedwa bwino. Njira imodzi ndiyo kutsuka zinthu zomangira zosakhazikika ndi laminar process gasi kudzera munjira yolondola ya gasi. Kuonjezera apo, pochepetsa mphamvu ya malo otentha, kutentha kwa ng'anjo ya vacuum ndikwabwino kwambiri, mpaka LK. Kawirikawiri, ng'anjo ya vacuum imakhala ndi ukhondo wabwino wa mlengalenga, magawo osinthika a ng'anjo ya vacuum sintering ndi kugwedezeka kwa gawo laling'ono, zomwe zimapangitsa kukhala luso lopangira zida zapamwamba (monga zipangizo zamankhwala). Makampani ambiri amakumana ndi madongosolo osinthasintha ndipo amafunika kupanga magawo okhala ndi mawonekedwe ndi zida zosiyanasiyana. The otsika athandizira ndi mkulu mkombero kusinthasintha kwa vacuum sintering ng'anjo adzalenga zinthu zabwino kwa iwo. Kuthamanga gulu la ng'anjo vacuum sikungangopereka mizere yopanga zowonjezera, komanso kuyendetsa njira zosiyanasiyana panthawi imodzi.

Komabe, ng'anjo zina zaukadaulo za vacuum sintering zomwe zili ndi zabwino zaukadaulo zomwe zili pamwambazi zimachepetsedwa ndi mphamvu zochepa zomwe zilipo. Kuipa kwawo pakuwonjezera zotulutsa ndi kugwiritsa ntchito mphamvu zochepa kumapangitsa kuti mtengo wa sintering wa magawo achepetse mtengo wosungidwa muzinthu zina za MIM.
