Kusanthula Kwathunthu Ndi Kukambitsirana Kwa Majenereta

(1) Kuwonongeka kwa minofu yomangika

Zotsatira za kafukufuku wa metallographic zinasonyeza kuti panali kusiyana koonekeratu kwa zonal muzinthuzo.Band microstructure ndi microstructure yomwe imapangidwa motsatira njira yachitsulo, makamaka yopangidwa ndi proeutectoid ferrite ndi pearlite.Chifukwa cha ma microstructure osiyanasiyana ndi katundu wa magulu oyandikana nawo, kupsinjika maganizo kudzachitika pakati pa magulu amphamvu ndi ofooka, zomwe zimapangitsa kuchepa kwa mphamvu zamakina ndi anisotropy yoonekeratu.Pansi pa mphamvu yakunja, kung'ambika kwa delamination kumachitika mosavuta motsatira kapangidwe kake, komwe kumayala maziko a kulephera koyambirira kwa zinthuzo.

(2) Chiyambi cha zomangira zomangira

Mzere kapangidwe ndi wamba chilema dongosolo mu otsika mpweya zitsulo, amene amayamba chifukwa cha zifukwa ziwiri: choyamba, kusankha crystallization wa chitsulo chosungunula pa ndondomeko crystallization wa zitsulo ingot kumabweretsa kugawa m'njira ya dendrite dongosolo.Pakugubuduza, coarse dendrite amatalika ndipo pang'onopang'ono amakumana ndi njira ya mapindikidwe, motero amapanga mawonekedwe apamwamba amagulu omwe atha komanso olemeretsa a carbon ndi alloy element.Pakuzizira pang'onopang'ono, ferrite ndi pearlite zimakhala zomangika kwambiri.Pachifukwa ichi, kuphatikiza kwamagulu ndiko maziko komanso chofunikira pakumanga minofu.Choncho ochiritsira annealing normalizing n'kovuta kuthetsa, kokha kudzera mkulu kutentha kufalitsa annealing ndi normalizing kamodzi kapena katatu kusintha kapena kuthetsa.

Chifukwa chachiwiri ndi bungwe la riboni lomwe limayambitsidwa ndi teknoloji yosayenera yogwira ntchito yotentha.Kutentha kotentha kukakhala m'gawo la magawo awiri, ferrite imapangidwa kuchokera ku austenite m'magulu azitsulo, ndipo undecomposed austenite imagawidwa m'magulu.Ikazizira kukhala A1, banded austenite imasandulika kukhala ngale.Zomangamanga zimatha kusinthidwa ndikuchotsedwa ndi normalizing kapena annealing.

(3) Kuyesera koyerekeza kuchotsa mawonekedwe omangika

Pofuna kudziwa chomwe chimayambitsa tsankho lamagulu ndikuchichotsa, zitsulo 20 zidasinthidwa molingana ndi njira yochiritsira yotentha.The ankachitira metallographic dongosolo (onani FIG. 6) anasonyeza kuti banded dongosolo la scaffold anali bwino kwambiri, kusonyeza kuti banded dongosolo la scaffold anayambitsa ndi zosayenera kutentha mankhwala ndondomeko, amene akhoza bwino ndi kuthetsedwa pambuyo mankhwala normalizing.Chifukwa chake, chomwe chimayambitsa kusweka kwa scaffold ndi njira zake zowongolera zimafunidwa kuchokera kuzinthu zama microstructure.

(4) Kusanthula kwathunthu

Kuchokera pakupanga ndi kukonza mawonekedwe akunja a bulaketi, mawonekedwe onse a bulaketi ndi ovuta, kuwotcherera ndi zoonekeratu, zizindikiro za mpeni ndi maenje zimatha kuwoneka paliponse, kusonyeza kuti khalidwe lonse lokonzekera silili labwino.Monga momwe zikuwonekera kuchokera kumapangidwe ndi malo ophwanyika a chithandizo mu FIG.1, kusweka kunachitika pakona ya mbale zachitsulo zopingasa komanso zowongoka, zomwe poyamba zinali ulalo wofooka pamapangidwe ake.Payenera kukhala gawo la kusintha kwa arc kuti muchepetse kupsinjika, koma pali njira zingapo zamakina.Kuwonongeka kodziwikiratu kotereku kudzadzetsa kupsinjika komwe kumatsegula njira zoyambira ndi chitukuko.

Pankhani ya luso lonse processing thandizo, otentha adagulung'undisa zitsulo mbale sanali normalized pamaso ntchito, kapena lolingana thupi ndi mankhwala anayendera mayeso, chifukwa mu zopangira ndi zolakwika structural mwachindunji anasamutsidwa ku ndondomeko yotsatira processing.Komanso, mbale zitsulo thandizo si annealed kapena normalized pambuyo kuwotcherera, amene mosalephera kuchititsa kukhalapo kuwotcherera yotsalira nkhawa ndi imathandizira Chimaona fracture ndondomeko thandizo kumlingo wakutiwakuti.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. yomwe idakhazikitsidwa mu 2006, ndiyopanga jenereta ya dizilo ku China, yomwe imaphatikiza kupanga, kupereka, kutumiza ndi kukonza jenereta ya dizilo .Zamalonda chivundikiro Cummins , Perkins, Volvo, Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai etc. ndi mphamvu osiyanasiyana 20kw-3000kw, ndi kukhala fakitale awo OEM ndi luso pakati.

Kuti mudziwe zambiri, pls lemberani Dingbo.
