Mayeso a UT a Steel Bar 4340:
Mipiringidzo yathu yachitsulo ya 4340 alloy imayesedwa mwamphamvu kwambiri (UT) kuti itsimikizire kuti mkati mwake muli bwino komanso kapangidwe kake kali kopanda chilema. Njira yoyesera yosawononga iyi imazindikira kusagwirizana kwamkati monga ming'alu, mabowo, ndi zinthu zina zomwe sizikuwoneka ndi maso. Kuwunika kwa UT kumachitika motsatira miyezo yamakampani, kuonetsetsa kuti bala lililonse likukwaniritsa zofunikira zapamwamba pa ntchito zaukadaulo wapamlengalenga, magalimoto, ndi ntchito zolemera. Kuwongolera kodalirika kwa khalidwe kumatsimikizira kukana kutopa, kukhulupirika kwa kapangidwe kake, komanso chidaliro cha makasitomala.
Mayeso a PMI a Alloy Bar 4340:
Kuti zitsimikizire kuti zinthuzo zikutsatira zomwe makasitomala akufuna komanso kuti zikugwirizana ndi zomwe makasitomala akufuna, mayeso a PMI (Positive Material Identification) amachitidwa pa AISI 4340 Alloy Steel Flat Bars pogwiritsa ntchito ma spectrometer apamwamba kapena X-ray fluorescence (XRF) analyzers. Njira yoyesera yosawononga iyi imatsimikizira kapangidwe ka mankhwala a nambala iliyonse ya kutentha, kuonetsetsa kuti ikukwaniritsa zofunikira za alloying element monga Ni, Cr, ndi Mo.
Mayeso a Kulimba kwa Mipiringidzo ya 4340:
Kuti atsimikizire momwe kutentha kumakhalira komanso kutsimikizira momwe makina amagwirira ntchito, kuyesa kuuma kumachitika pa AISI 4340 Alloy Steel Flat Bars pogwiritsa ntchito njira za Rockwell kapena Brinell. Pa mipiringidzo yozimitsidwa komanso yofewa, kuchuluka kwa kuuma kwa nthawi zonse ndi 24 mpaka 38 HRC. Kuuma kwa zinthu kumalembedwa m'malo osiyanasiyana pamwamba ndi m'mbali kuti zitsimikizire kufanana. Zotsatira zake zimathandiza kutsimikizira kuti chitsulocho chili choyenera kugwiritsidwa ntchito molimbika komanso movutikira.
Lipoti Loyesa la 4340 Steel Flat Bar:
Malinga ndi: Standard ASTM A370-24a.
Kugwiritsa ntchito AISI 4340 Alloy Bar
1. Misonkhano ya Zida Zokwerera Ndege:
Amagwiritsidwa ntchito kwambiri popanga zida zonyamulira monga zingwe ndi maulumikizidwe, pomwe mphamvu zake zokoka komanso kulimba kwake zimatsimikizira magwiridwe antchito odalirika pansi pa kupsinjika kwakukulu.
2. Machitidwe Oyendetsera Magalimoto:
Pogwiritsidwa ntchito popanga zida zofunika kwambiri monga magiya ndi ma shaft, AISI 4340 imapereka kulimba kwabwino komanso magwiridwe antchito abwino m'malo okhala magalimoto ambiri.
3. Zida Zopangira Hydraulic System:
Chogwiritsidwa ntchito pogwiritsira ntchito makina a hydraulic, alloy iyi ndi yabwino kwambiri polimbana ndi kupsinjika ndi kugwedezeka kwa makina, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito ma pistoni a hydraulic, masilinda, ndi zolumikizira.
4. Ma Crankshaft a Injini Ogwira Ntchito Kwambiri:
Yogwiritsidwa ntchito popanga crankshaft m'mainjini ogwira ntchito bwino, mphamvu yake yotopetsa komanso kulimba kwake kumatsimikizira kuti imagwira ntchito nthawi yayitali ikadzaza ndi zinthu zosiyanasiyana.
5. Zigawo Zotumizira Mphamvu Zamakampani:
Imagwiritsidwa ntchito popanga magiya ndi ma shaft olemera a zida zotumizira mphamvu, komwe imakana kuwonongeka ndi kusokonekera m'makina ovuta.
