High silicon dzimbiri zosagwira chitsulo choponyedwa chavuvu

Chitsulo chachikulu cha silicon corrosion resistant cast cast iron of valve material Mulingo uwu umatchula zofunikira zaukadaulo, njira zoyesera, zitsanzo ndi malamulo oyendera, kuyika chizindikiro, kuyika, kusungirako ndi zoyendera zachitsulo chapamwamba cha silicon corrosion resistance. Muyezo uwu umagwira ntchito pazitsulo zapamwamba za silicon corrosion zosagwira ntchito ndi silicon zomwe zili 10, 00% ~ 15. 00%. Zojambula zomwe zikuwonetsa mawonekedwe, mawonekedwe ndi miyeso, malangizo oyeretsera, zojambula zosonyeza miyeso yayikulu ndikupereka kulolerana konse. Ngati wofunsayo akupereka chitsanzo, kukula kwa kuponyera kudzakhala molingana ndi kukula komwe kumasungidwa kwa chitsanzocho. Kaya kuyesa kwa hydraulic kumafunika, ndipo ngati ndi choncho, kukakamizidwa koyesa ndi kutayikira kovomerezeka kuyenera kuwonetsedwa. range Muyezo uwu umatchula zofunikira zaukadaulo, njira zoyesera, sampuli ndi malamulo oyendera, kuyika chizindikiro, kulongedza, kusungirako ndi zofunika zoyendera pachitsulo chapamwamba cha silicon corrosion resistant cast. Muyezo uwu umagwira ntchito pazitsulo zapamwamba za silicon corrosion resistant cast iron zomwe zili ndi silicon 10, 00% ~ 15. 00%. Chikalata chodziwika bwino Zomwe zili m'malemba otsatirawa zimakhala za Mulingo uwu potengera Mulingo uwu. Pamatchulidwe amasiku, zosintha zonse (kupatulapo erratum) kapena zosinthidwa sizikugwira ntchito pa Mulingo uwu; komabe, omwe akuchita mgwirizano pansi pa Mulingo uwu akulimbikitsidwa kuti afufuze kupezeka kwa *** mitundu ya zolembazi. Kwa maumboni omwe sanatchulidwe, matembenuzidwe awo amagwira ntchito pamlingo uwu. Chidziwitso cha oyitanitsa Zambiri zamadongosolo otsatirawa zidzaperekedwa ndi wofunsayo: a) Nambala yokhazikika ya kuphedwa. b) mtundu wapamwamba wa silicon cast iron. c) Chiwerengero cha osewera. d) Kutaya kulemera. e) Zojambula zomwe zikuwonetsa mawonekedwe, mawonekedwe ndi miyeso, malangizo oyeretsera, zojambula zowonetsa miyeso yayikulu ndikupereka kulolerana konse. Ngati wofunsayo akupereka chitsanzo, kukula kwa kuponyera kudzakhala molingana ndi kukula komwe kumasungidwa kwa chitsanzocho. Zosankha kuti mudziwe: a) Chikhalidwe cha kutentha kwa kuponyera pa nthawi yobereka; b) Kupereka lipoti la kusanthula kwa mankhwala; c) Kaya kuyesa kupindika kumafunika; d) Ngati kuyezetsa kwa hydraulic kumafunika, ndipo ngati ndi choncho, kukakamizidwa kwa mayeso ndi kutayikira kovomerezeka kuyenera kuwonetsedwa. e) Kuyika kulikonse kwapadera, kuyika chizindikiro, etc. Njira yopangira Pokhapokha ngati tafotokozera mwanjira ina, njira yosungunula ndi kuponyedwa kwazitsulo zidzatsimikiziridwa ndi Wopereka. Zofunikira paukadaulo Kalasi ndi kapangidwe kake kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kachitsulo kamagwirizana ndi kaphatikizidwe ka GB/T 5612, kagawidwe ka magawo anayi. High silicon corrosion resistant cast iron grade and molingana chemical composition taonani Kuvomerezedwa kwa chitsulo chapamwamba cha silicon corrosion corrosion resistant iron cast, chidzatengera zomwe zili mu Table 1. Mechanical property The mechanical properties of high silicon corrosion resistant cast cast. chitsulo nthawi zambiri sichimatengedwa ngati maziko ovomerezeka. Ngati kufunidwa ndi wofuna, ndodo yoyesera idzayesedwa kuyesedwa kuti idziwe mphamvu yopindika ndi kupotoza, ndipo zotsatira zoyesa zidzatsatira zomwe zili mu Table 2. (2) High silicon corrosion resistant iron iron ndi mtundu wa Chimaona zitsulo zakuthupi, mu structural kamangidwe ka castings ake sayenera lakuthwa ndi lakuthwa mtanda gawo kusintha. Ma geometry ndi kukula kwa ma castings akuyenera kugwirizana ndi zojambula kapena zofunikira za wofunsayo. Ngati Demander alibe zofunikira zapadera pakulolera kwapang'onopang'ono kwa kuponyera, zofunikira za GB/T 6414 ziyenera kutsatiridwa. Castings ayenera kutsukidwa, nakonza kwambiri "mnofu", kuchotsa kuthira riser, pachimake fupa, dongo mchenga ndi zotsalira zamkati patsekeke, ndi zina zotero. The otsala kuthira riser, kuphimba msoko, ntchentche zouluka ndi ukhondo wamkati patsekeke wa castings ayenera kugwirizana ndi kujambula. kapena zofunikira zaukadaulo za wogula kapena mgwirizano wadongosolo pakati pamagulu awiriwo. Pamwamba: chitsulo chachitsulo chosamva dzimbiri cha silicon (I) Ndodo yoyesera Mayeso opindika a chitsulo chosamva dzimbiri cha silicon amatengera chitsulo chimodzi choyesera chokhala ndi mainchesi 30mm ndi kutalika kwa 330mm popanda makina amakina. Mafotokozedwe ake akuwonetsedwa mu Chithunzi 1. Chigawo: millimeter Zindikirani: Kukula kovomerezeka kwa bar yoyesera kuyenera kukhazikika mpaka 540 ℃ mu nkhungu mchenga usanagwe, ndipo kupanikizika kotsalira kuyenera kuchotsedwa musanayese kuyesa. Ndodo imodzi yoyeserera iyenera kutsanuliridwa mumtanda womwewo wachitsulo chamadzimadzi monga kuponyera (zoyambira ndi zomaliza sizigwiritsidwa ntchito). Mu nkhungu yoponyera yomweyi, ndodo zingapo zoyesera zimatha kutsanuliridwa nthawi imodzi, ndipo ndondomeko yowonetsera ikuwonetsedwa mu Chithunzi 2. Unit: millimeter Geometric ndi dimensional tolerances High silicon corrosion resistant iron iron ndi mtundu wa chitsulo chosasunthika, ndi chakuthwa. kusintha kwa gawo laling'ono sikuyenera kufunidwa pakupanga mapangidwe ake. Ma geometry ndi kukula kwa ma castings akuyenera kugwirizana ndi zojambula kapena zofunikira za wofunsayo. Ngati Demander alibe zofunikira zapadera pakulolera kwapang'onopang'ono kwa kuponyera, zofunikira za GB/T 6414 ziyenera kutsatiridwa. Kupatuka kwa kulemera Ngati palibe chofunikira chapadera cha kuponyera kulemera, zofunikira za GB/T 11351 zidzatsatiridwa. Ubwino wapamtunda Kuvuta kwa ma castings kudzagwirizana ndi GB/T 6061.1 kapena zojambula za ofunsira kapena zofunikira zaukadaulo. Castings ayenera kutsukidwa, nakonza kwambiri "thupi", kuchotsa kuthira riser, pachimake fupa, dongo mchenga ndi zotsalira zamkati patsekeke, etc. The otsala kuthira riser, kuphimba msoko, ntchentche zouluka ndi ukhondo wamkati patsekeke wa castings ayenera kugwirizana ndi kujambula. kapena zofunikira zaukadaulo za wogula kapena mgwirizano wadongosolo pakati pamagulu awiriwo. Kuponyera kuwonongeka Sipadzakhala zofooka zoponya zomwe zimachepetsa mphamvu ndikuwononga maonekedwe a mankhwala. Zolakwika zovomerezeka ndi njira yovala zovala zidzavomerezedwa ndi maphwando. Chithandizo cha kutentha High silicon kuponyedwa chitsulo nthawi zambiri ntchito kutentha kutentha boma (kuchotsa nkhawa yotsalira). Kwa ma casting ang'onoang'ono a mawonekedwe osavuta, ngati aperekedwa ngati oponyedwa, onse awiri ayenera kuvomereza. Castings adzapatsidwa chithandizo cha kutentha kuti achotse kupsinjika kotsalira. Ngati wofunsayo alibe zofunikira zapadera, kuponyera kungathe kuchitidwa m'njira zotsatirazi: Kuponyera mchenga kumalo ofiira otentha, mwamsanga kuthetsa kukana kwa mawotchi kuti shrinkage yaulere ya kuponyera, kuthetsa kuponyera risers, kuponyera kofiira kofiira mwachindunji mu kutentha kwa kutentha. ng'anjo preheating kuposa 600 ℃, ndiye pang'onopang'ono Kutentha, ndi otsika kutchinjiriza kutentha 870 ℃. Pa kutentha kuposa 870 ℃, malinga ndi makulidwe akuluakulu a khoma la castings, nthawi ya kutchinjiriza iyenera kukhala 1.h/25mm, koma nthawi yocheperako sayenera kukhala yosachepera 2h. Kenako imakhazikika pa liwiro losapitilira 55 ℃/15 min. Imazizira mpaka 205 ℃ ndi ng'anjo ndi mpweya utakhazikika pa kutentha kwabwino. Chofunikira chapadera Ngati wofunsayo ali ndi zofunikira zoyezetsa maginito, kuyezetsa kwa akupanga, kuyesa kwa X-ray, ndi zina zotero, wofunsayo ndi wofunayo adzakambirana ndikuchita molingana ndi zomwe GB/T 9444, GB/T 7233 ndi GB/T 5677 pa. Njira yoyesera Kusanthula mankhwala Njira zodziwika bwino, zowoneka bwino kapena zida zina ndizovomerezeka koma ziyenera kukhala zofananira kuti zipereke zotsatira zomwezo. Ochiritsira zitsanzo njira kusanthula mankhwala zidzachitika malinga ndi GB/T 20066. The arbitrated kusanthula carbon, pakachitsulo, manganese, sulfure ndi phosphorous mu mankhwala zikuchokera anawerengedwa molingana GB/T 20123 kapena GB/T 223.69,GB/ T 223.60, GB/T 223. 58 or GB/T 223. 64,GB/T 223. 3 or GB/T 223. 59 or GB/T 223. 61,GB/T 223. 53 Chrome, key, copper arbitration kusanthula kudzachitika motsatira GB/T 223.11 kapena GB/T 223.12,GB/T 223.26,GB/T 223.18 kapena GB/T 223.19 kapena GB/T 223.53, motero.
