Udindo wa aluminiyamu kutentha kutentha ndikuwongolera makina a zida, sakani nkhawa zotsalira ndikuwongolera makina opanga zitsulo. Malinga ndi zifukwa zosiyanasiyana chithandizo chamankhwala, njira zitha kugawidwa m'magulu awiri: chithandizo cha preheat ndi mankhwala omaliza kutentha.
Cholinga cha chithandizo cha preheat ndikusintha magwiridwe antchito, chotsani kupsinjika kwamkati ndikukonza mawonekedwe abwino achitsulo cha chithandizo chomaliza kutentha. Njira yake yochizira kutentha imaphatikizana ndi kukalamba, kukalamba, kupsinjika ndi kusala;
1) Kuyamwa ndi kusintha
Kuyamwa ndi kusilira kumagwiritsidwa ntchito pochita bwino kwambiri. Carbon Steel ndi Alloy Steel wokhala ndi zomwe zili ndi zokulirapo kuposa 0,5% nthawi zambiri zimakhazikitsidwa kuti muchepetse kuuma kwawo komanso kosavuta kudula; Carbon steel ndi alloy chitsulo chokhala ndi zokhudzana ndi mpweya zosakwana 0,5% amagwiritsidwa ntchito popewa kumamatira mpeni pomwe kuuma kumakhala kochepa kwambiri. Ndipo gwiritsani ntchito mankhwalawa. Kuyaka ndi njira yothetseranso kungayambitsebe tirigu ndi mawonekedwe ofanana, ndipo konzekerani mankhwala otsatira. Kuyamwa ndi kusilira nthawi zambiri zimakonzedwa pambuyo poti zisapangidwire ndipo musanayambe kuyenda.
2) Kuchiritsa
Chithandizo cha okalamba chimagwiritsidwa ntchito pochotsa nkhawa zamkati zomwe zimapangidwa popanga ndi makina.
Pofuna kupewa kugwira ntchito kwambiri, kwa magawo ambiri, ndikokwanira kukonza chithandizo chimodzi musanamalize. Komabe, pamagawo ofunikira kwambiri, monga bokosi la mbig makina obowola, ndi zina kapena zingapo kapena zingapo zokalamba ziyenera kukonzedwa. Magawo osavuta nthawi zambiri samafunikira chithandizo chamavuto.
Kuphatikiza pa zinyalala, kwa zigawo zina zowongolera, monga kukhwima kopanda pake, kuti muchepetse kupsinjika kwamkati ndi kuwongolera magawo, chithandizo chambiri chokalamba nthawi zambiri chimakonzedwa pakati pa makina owoneka bwino ndi kumaliza. Pazigawo zina zazing'ono, kukalamba kuyeneranso kukonzedwa pambuyo powongoka.
3) Kukhazikika ndi kusanja
Kuumitsa ndi kusanthula kumatanthauza kutentha kwambiri pambuyo pokhomerera. Itha kupeza yunifolomu komanso mawonekedwe a sorbiter, omwe ndi kukonzekera kuchepetsa kuwonongeka pamalo okhwima ndi mankhwalawa. Chifukwa chake, kupsinjika ndi kupsa mtima kumatha kugwiritsidwa ntchito ngati mankhwala a preheat.
Chifukwa cha makina abwino a mitu yopumira komanso magawo, imatha kugwiritsidwanso ntchito ngati kutentha komaliza kutentha kwa magawo ena omwe safuna kuuma kwambiri ndikuthetsa kukana.
Cholinga cha chithandizo chomaliza kutentha ndikusintha zinthu monga kuuma, kuvala kukana ndi mphamvu. Njira yake kutentha imaphatikizira kuwuma, kusanja ndi kupukutira, komanso mankhwalawa.
1) Kukhazikika
Kuzimitsa kumagawidwa pamalo opukutira ndi kukhazikika konse. Zina mwazomwe zimawagwiritsa ntchito kwambiri zimagwiritsidwa ntchito kwambiri chifukwa chodetsa pang'ono, makutidwe ndi omwe amasungidwa, komanso kuvala bwino komanso kukana kwamphamvu. Pofuna kusintha makina owoneka bwino pamiyala, chithandizo chamatenthedwe monga chokhazikika kapena kusangalatsa nthawi zambiri chimafunikira chithandizo chamachipatala cha kutentha. Njira yake ikuyenda bwino ndikuti:
2) Kusanja ndi kukhazikika
Kusanja ndi kuwunjika ndikuwonjezera zomwe zili pansi, ndipo pambuyo poumitsa, ndipo mkati mwake mumapeza kuuma kwakukulu, pomwe gawo lalikulu limakhalabe mphamvu komanso chipilala chovuta komanso chipilala. Kukongoletsa kumagawidwa mokwanira komanso kusamala pang'ono. Pakakhala pang'ono potengera pang'ono, njira zotsutsa-zotsutsana ziyenera kutengedwa zigawo zosagwiritsa ntchito zonyamula. Popeza kusanja ndi kupukutira kumapangitsa kusokonezeka kwakukulu, ndipo kuya kwakuti nthawi zambiri kumakhala pakati pa 0,5 ndi 2 mm, njira yolerera nthawi zambiri imakonzedwa pakati pa semi-kumaliza.
Njira yoyendera nthawi zambiri ili: kulekanitsa, kusintha, kusinthana, kusanja koyipa, semi-kumamaliza, kukonza ndi kufota. Pamene gawo lopanda kanthu la gawo lotetezedwa ndi liwiro limatengera njira yochotsa mafuta ochulukirapo atatha kukulira malire, njira yochotsa mafuta ochulukirapo iyenera kukonzedwa pambuyo pothirira ndikuzimitsa.
3) Chithandizo cha Nitring
Nitring ndi njira yolumikizira ma atomu a nayitrogen kuti ikhale yopanda nitrogen-couses. Wosanjikiza wa nitring amatha kusintha, kuvala kukana, kutopa kwambiri ndi kukana kwa gawo la gawo. Popeza kutentha kwa chisamaliro kumakhala kotsika, kuwonongeka kwake ndikochepa, ndipo mawonekedwe a nitring ndiocheperako, osaposa 0,6 ~ 0.7mm, njira yodziwikiratu iyenera kukonzedwa mochedwa. Kuti muchepetse kuwonongeka panthawi yomwe ikuwaimira, nthawi zambiri pamafunika kusamalira mpumulo kuti muchepetse.
