25CrMo4 aloyi zitsulo ndiotsika aloyi structural zitsulozakuthupi, za Cr-Mo mndandanda aloyi structural zitsulo. Kudzerakutentha mankhwalandondomeko, kapangidwe ndi ntchito za nkhaniyi akhoza kwambiri kulamulidwa, ndi mphamvu mkulu ndi kuuma, komanso kukana kuvala bwino ndi kukana dzimbiri. Makina ake apamwamba kwambiri komanso kukana kutentha kumapangitsa kuti azigwiritsidwa ntchito kwambiri m'magawo osiyanasiyana a uinjiniya, makamaka nthawi zomwe zimafunikira mphamvu zambiri komanso kukana kutentha kwambiri.Investment castingndi imodzi mwa njira zodziwika bwino zopangira zida zolondola ngati izi.
Zinthu Zakuthupi
1.Chemical Composition
Zomwe zimapangidwa ndi chitsulo cha 25CrMo4 alloy makamaka zimaphatikizapo chromium ndi molybdenum, zomwe zimagwira ntchito yofunika kwambiri pakuwongolera mphamvu ndi kulimba kwa zinthuzo. Kuphatikizika kwa chromium kumawonjezera kukana kwa dzimbiri ndi kuuma kwa zinthu, pomwe molybdenum imathandizira kutentha kwambiri komanso kukana kutopa. Kuphatikiza apo, zomwe zili mu kaboni ndi manganese zimapangidwiranso bwino kuti ziwonjezeke komanso kutheka, kuti zinthuzo zizichita bwino pansi pamikhalidwe yovuta kwambiri yogwirira ntchito.
2. Katundu Wamakina
Zinthuzo zimakhala ndi mphamvu zowonongeka kwambiri komanso zokolola, zimatha kupirira katundu wolemetsa ndi mphamvu zowonongeka, ndikuonetsetsa kukhazikika ndi chitetezo cha kapangidwe kake pansi pa katundu wambiri. Kukana kwake kuvala kumapangitsa kuti mutu wokhazikika ukhalebe ndi moyo wabwino wautumiki m'malo okhala ndi kuvala pafupipafupi, kuchepetsa kuchuluka kwa kukonzanso ndikusinthanso, potero kumapangitsa kuti ntchito zonse ziziyenda bwino.
3. Ntchito Yochizira Kutentha
Kuchita kwa chitsulo cha 25CrMo4 alloy kumatha kusintha kwambiri kudzera munjira zochizira kutentha monga normalizing, kuzimitsa ndi kutentha. Njirazi zimatha kusintha ma microstructure azinthuzo kuti athe kukhalabe ndi pulasitiki wabwino komanso kulimba kwinaku akuwongolera mphamvu, kusinthira kuzinthu zosiyanasiyana zogwirira ntchito komanso zofunikira pakugwiritsa ntchito. Kutengera ndi malo ogwiritsira ntchito, magawo opangira kutentha amatha kuwongoleredwa bwino kuti awonetsetse kuti mutu uliwonse wokwera umachita bwino pakugwiritsa ntchito kwake.

Kugwiritsa Ntchito Ma Frames
1. Zipangizo zamakina:
Mu zipangizo zamakina, mitu yokhazikika yotereyi ingagwiritsidwe ntchito kugwirizanitsa ma shafts, ma levers kapena mbali zina zomwe ziyenera kulumikizidwa mwamphamvu. Zitha kuonetsetsa kuti zigawozi zimakhalabe zolumikizidwa mokhazikika zikamathamanga kwambiri kapena kupanikizika kwambiri.
2. Zida zapakhomo:
M'makina otsuka, makina ochapira kapena zida zina zapakhomo, mitu yokhazikika yotere imatha kugwiritsidwa ntchito ngati zida zamkati, monga mapaipi olumikizira, ma shaft amagalimoto kapena zida zina zazikulu. Kapangidwe kake kolimba komanso kamangidwe kosavuta kulumikiza kumapangitsa kukonza ndikusintha magawo kukhala kosavuta.
3. Zida zamafakitale:
M'ma workshops kapena mafakitale, mitu yokhazikika yotereyi ingagwiritsidwe ntchito ngati zigawo za zida zamagetsi, zida zamanja kapena zomangira. Amathandizira kukhazikika kwa zida ndikuwongolera magwiridwe antchito ndi chitetezo.
4.Zigawo zamagalimoto:
Pankhani yopanga magalimoto kapena kukonza, mitu yokhazikika imatha kugwiritsidwa ntchito kulumikiza kapena kukonza zida zamagalimoto, monga magawo a injini, makina oyimitsa kapena ma brake system. Kukhalitsa kwake ndi kudalirika ndizofunikira kuti zitsimikizire kuti galimotoyo ikugwira ntchito ndi chitetezo.
