Awiri njira zitsulo kutentha mankhwala

Njira yopangira kutentha kwachitsulo nthawi zambiri imaphatikizapo njira zitatu: kutenthetsa, kusungunula, ndi kuziziritsa.Nthawi zina pamakhala njira ziwiri zokha: kutentha ndi kuziziritsa.Njirazi ndizolumikizana ndipo sizingasokonezedwe.

1.Kutentha

Kutentha ndi imodzi mwa njira zofunika kwambiri zochizira kutentha.Pali njira zambiri zopangira kutentha kwachitsulo.Choyamba chinali kugwiritsa ntchito makala ndi malasha monga gwero la kutentha, ndiyeno kugwiritsa ntchito madzi ndi mpweya.Kugwiritsa ntchito magetsi kumapangitsa kutentha kukhala kosavuta kuwongolera komanso kulibe kuwononga chilengedwe.Magwero otenthawa atha kugwiritsidwa ntchito potenthetsera mwachindunji, kapena kutenthetsa mwachindunji kudzera mumchere wosungunuka kapena chitsulo, kapena tinthu toyandama.

Chitsulo chikatenthedwa, chogwiritsira ntchito chimawonekera mumlengalenga, ndipo ma oxidation ndi decarburization nthawi zambiri zimachitika (ndiko kuti, mpweya wa carbon pamtunda wa chitsulo umachepetsedwa), zomwe zimakhala ndi zotsatira zoipa kwambiri pamtunda wa chitsulo. mbali pambuyo kutentha mankhwala.Choncho, zitsulo nthawi zambiri zimayenera kutenthedwa m'malo otetezedwa, mumchere wosungunuka, ndi mu vacuum.Kutentha kodzitchinjiriza kumathanso kuchitidwa ndi zokutira kapena njira zoyika.

Kutentha kwa kutentha ndi chimodzi mwazinthu zofunika kwambiri za ndondomeko ya chithandizo cha kutentha.Kusankha ndi kulamulira kutentha kutentha ndi nkhani yaikulu kuonetsetsa ubwino wa kutentha kutentha.Kutentha kwa kutentha kumasiyanasiyana malinga ndi zitsulo zomwe zimagwiritsidwa ntchito komanso cholinga cha kutentha kwa kutentha, koma nthawi zambiri zimatenthedwa pamwamba pa kutentha kwa chikhalidwe china kuti mupeze kutentha kwakukulu.Komanso, kusintha kumafuna nthawi yochuluka.Choncho, pamene pamwamba pa zitsulo workpiece kufika chofunika Kutentha kutentha, ayenera anakhalabe pa kutentha kwa nthawi inayake kuti kutentha mkati ndi kunja kugwirizana ndi kusintha microstructure kukhala wathunthu.Nthawi imeneyi imatchedwa nthawi yogwira.Mukamagwiritsa ntchito kutentha kwamphamvu kwambiri komanso kutentha kwapamwamba, kuthamanga kwa kutentha kumakhala kofulumira kwambiri ndipo nthawi zambiri kulibe nthawi yogwira, pomwe nthawi yosungira kutentha kwa mankhwala nthawi zambiri imakhala yayitali.

2.Kuziziritsa

Kuziziritsa ndi gawo lofunikira kwambiri pakuchiritsa kutentha.Njira zoziziritsira zimasiyanasiyana malinga ndi momwe zimakhalira, makamaka kuwongolera kuzizira.Nthawi zambiri, kuziziritsa kumakhala ndi kuzizira kocheperako, kuzizira kumakhala kozizira kwambiri, ndipo kuzimitsa kumakhala ndi kuzizira kofulumira.Komabe, pali zofunika zosiyanasiyana chifukwa cha mitundu yosiyanasiyana yachitsulo.Mwachitsanzo, chitsulo chowumitsidwa ndi mpweya chikhoza kuumitsidwa pamlingo wozizira womwewo monga normalizing.
