Coquille - chii ichi?

Coquille - a reusable muforoma rekukuputsirai simbi. Kungava kana mahwanda (muzvikamu zviviri), kana kwete (kuzungura chill no). Permanent muforoma Kudzingwa ane wandei zvakwakanakira pamusoro mumuhara, asi pane dzimwe zvainovhiringidzawo Somuenzaniso, pamwe nedare Kudzingwa castings dzinoda kupisa kurapwa.

zvakwakanakira

Panguva paumbwe chakakandirwa kunoitika ndichibvunza kuchinjwa kupisa kubva yakaumbwa simbi iri simbi yezvidhinha. mugumisiro Izvi zvinopa yepamusoro arambe achirema, nani zvemaziso ehupfumi ari simbi, mukuru nemazvo, nani mamiriro uye yakaderera pamusoro roughness tichienzanisa castings kubva nejecha anoumba.

chill no Kudzingwa muitiro kunoratidzwa ndechokuti simbi muforoma (simbi muforoma) inogona kushandiswa kakawanda. Wakaitwa pamatunhu simba zvinhu, mauri kushanda pose Foroma rinoitwa zvakanyatsorurama. Izvi kunonatsiridza pamusoro unhu castings uye nokuda yakakwirira chafariz conductivity ari kuraswa yezvidhinha nokukurumidza zvigare.

Chimwe chakanakira pakushandisa hwava kuderera Kudzingwa jecha anoumba - yakaderera dhigirii kwohumwe zvokuimba kubudiswa kubva castings, uye izvi kunoderedza zvinhu kudyiwa panguva nokuumbwa.

Health uye Ecology

Chill ichikandamo 2-3 nguva kunowedzera negoho nokuda kwacho havachafaniri mabhodhoro nguva-akavhiyiwa akadai gadziriro musanganiswa, kuchenesa uye kuumbwa zvigadzirwa. Sezvo kugadzirwa nzvimbo iri ipfupi, nemari kugadzira uye kuvakwa zvinomera zvitsva iduku zvikuru.

Of kwacho anobvisa yakawanda hakuvaki kushanda kwacho sezvo kuzununguka-panze siyana, kuchenesa castings uye fettling. Izvi zvinobatsira kwete chete kuvandudza mamiriro kumabasa, asi kuderedza kushatiswa kwezvakatipoteredza.

kutadza

Manufacturing mari yacho achifa zvinodhura chaizvo nokuda kunzwisisa izvi. In pamberi Kunoshayisa ari kuraswa muforoma mutengo kunowedzera nokuda kudiwa complicating maumbirwo: kushandiswa inoisa, kuraswa uye kupatsanurwa jecha simbi tsvimbo.

Upenyu achifa kunotemwa maererano nokuwanda unhu hwakanaka castings kuti unogona kugamuchira. Kupikiswa chimiro anosarudza upfumi feasibility acho, kunyanya panguva kukanda simbi nesimbi. Kuvandudza upenyu anoumba ndeimwe guru rwokugadzira matambudziko ari mumunda ichi okuwana.

Nokuda nokukurumidza kutonhora uye thickening uchanyangadika vakawedzera kuwana mutete-akavakirirwa nyaya pamwe refu chill no Kudzingwa. Izvi zvinotungamirira ndechokuti kukandira simbi ava zvikukutu, bleached rukoko. Form pliable, izvozvo zvingaita kuti mupfungwa uye makatsemuka muna castings. Kana tichishandisa kuraswa jecha chinoumba ipfupi zvakarurama castings kunowedzera pemvura roughness panzvimbo kunyorerana neshamhu.

unhu castings

Kudzingwa chimiro uye kushamwaridzana kumusoro kunyatsoshanda. Zvisinei, vachikanda solidifies uye inotonhodza mujecha muchimiro yakareba kupfuura achifa, ivo nokugaramo panguva jecha muforoma rinowanzova nani, zvichiita zvakaoma zvikuru kurimwa neurongwa hwava kuderera Kudzingwa castings vasiri ruchiyerera chiwanikwa, uye zvinoita akavarambidza parameter akadai kutsinga Kukura uye shoma ukobvu rusvingo. Aluminum Kudzingwa chill no (uyewo mhangura nezvimwe chawo simbi) ndiyo zvakakurumbira Russia.

Zvisinei, nokuda nokukurumidza kutonhora kunogona kuwanikwa asiri porous, wakaisvonaka-grained yakarongeka, izvo anowedzera kwete chete simba asiwo ductility zvichiguma Kudzingwa. In kugadzirwa nyaya zvesimbi kubudikidza uchafira vachikanda nhamba matambudziko: nokuda chairwo crystallization mu castings zvingaite carbides, ferrite-graphite eutectic. Izvi lowers ari kuoma uye mukurumari kuti kukandira simbi. Bleached pamusoro rukoko mu castings dzakadaro zvakaoma chaizvo, saka kuti zvigadzirwa vari akakodzera achicheka chete pashure kupisa kurapwa (annealing), iyo anobvisa chill.

Sechivako muchimiro

Coquille - iri, sezvo ari kutonga, anoumba maviri, izvo vakatasva okusungisa (Pin) uye pakarepo asati kudira yakaumbwa nesimbi yakanyungudutswa muforoma dzevhudzi vari wakaiswa. Zvakawanwa Kudzingwa rinoitwa kuburikidza inonzi simba makomba mhepo uye vhendi plugs. Metal anoumba pasina connector zvinhu anonzi guda Coquille.

Asati kudira dzika, akaumbwa kushanda pose kubatwa rukoko zvinhu kunodzivirira resimbi muforoma kubudikidza chafariz kuvhunduka kubva chimbichimbi tembiricha vanomutswa. chiyero yakadaro kunodzivisa yokuvira kutsinga pamwe chakuvhuvhu.

Steel nesimbi

Chill kukanda simbi uye simbi kunoitika kushandisa pulverized Goldstone, graphite, mvura girazi uye refractory nevhu somunhu refractory unhani. Asati rokuzadza simbi muforoma anofanira neshungu kune imwe tembiricha iyo kunoenderana pakukora masvingo kutsinga uye chiwanikwa kushandiswa.

Huru chinodiwa kuti vakasangana nevanhu mashoko ose Foroma - iri kuramba teploudaram hakudzivisiki nokudurura simbi yakanyungudutswa. Rinoshandiswa pakugadzira anoumba, wachena kukandira simbi, ductile simbi, STRUCTURAL, carbon uye chiwanikwa simbi, uye alloys nemhangura uye aruminiyamu.

Vanenge vachitsigira simbi muforoma

ruzivo mhando iyi, iyo nokubatanidza zvazvakanakira mumuhara uye zvechigarire muforoma Kudzingwa nekuipira zvose nzira dziri ndokudzora. Michina iyi kunoratidzwa kwete chete pakakuvara kuoma asiwo pliability kuti anobvumira kuti pave mukuru-zvakarurama castings, uye kana zvichienzaniswa mumuhara jekiseni, zvinodhura Kuumbwa zvinhu mari zvishoma.

Lined simbi muforoma iri kugadzirwa nokuzadza nzvimbo pakati simbi kuraswa womuenzaniso uye romukati pechiso chakuvhuvhu. The anowanzodanwa akashandisa nzira peskoduvny uye filler. Nokuti achizadza utore jecha-nebwe nezvakavhenganiswa, sezvamakaropafadzwa unobatanidza chinhu ari phenol formaldehyde nebwe (2-2.6%) uye methenamine (anenge 10% zvakayerwa), uye kuzvipira kuomesa (bhainda - mvura girazi) uye zvedongo nziyo (chokuedza - ethyl silicate). The kufa uye Kudzingwa muenzaniso vane tembiricha rworwendo 200, kupisa zvitange nezvakavhenganiswa, izvo anoomesa nokuumba munhu cladding rukoko 3-5 mm gobvu. Kwakajairika kana goko cores zvinoshandiswa kuita in ari castings.

Kudzingwa urongwa

The uchafira zvinenge zvakazara paiva refractory zvinhu zviri kupopotedzana. The uchishandisa tembiricha inofanira kuva madhigirii mazana zviviri, asi hakubvi chete pamusoro chiwanikwa rakashandiswa Kudzingwa, asiwo kukura kuraswa, pakukora masvingo aro uye zvivako kuti zvinodiwa izvozvo. Pashure kudziyisa simbi muforoma anogona kuisa pematanda, zvedongo kana jecha, kana zviri Chokwadi, waiti kutsinga plan, uye ipapo Foroma sezvikamu zvabatanidzwa uye akakiyiwa zvakasimba nokuda chaiwo clip. Kana kugadzirwa kutsinga kunoitika muna clamping michini, rinoshandisa yayo nokukiya mashandiro siyana. Pashure gadziriro izvi simbi muforoma anogona achazadzwa yakaumbwa nesimbi yakanyungudutswa.

Kana achibudisa akatotora kuwana imwe simba inogona aoma kubvisa tsvimbo zvesimbi. Izvi vakazoroorwa hwezvekukurukurirana ari dzokubudisa okupedzisira castings pakati pematanda nokuda kuderera zvavaida pamusoro navo solidifying simbi.

Mushure kutsinga haachandidi kune kutsvakwa tembiricha, chicherwa muforoma inogona kuvhurwa. Panguva iyi zvikaramba simbi pematanda, uye kuraswa vakabviswa chakuvhuvhu. Sand nembariro vari agogodza panze, purofiti, risers uye vamhanyi dzinobviswa uye kugadzirwa chigadzirwa yepamusoro kuzvidzora, pashure iyo yose muitiro inogona kudzokororwa.

Pamberi kugadzirwa idzva chakakandirwa nyatsonzvera kuparadzanisa ndege uye pechiso chakuvhuvhu. The refractory sezvamunoita rinoshandisirwa kamwe kana kaviri pa kusuduruka, asi panyaya peeling kubva nokushanda pamusoro rukoko zvakakodzera kudzorera.
Coquille anofanira kuiswa kuna uchishandisa tembiricha zvakare sezvo inotonhodza panguva kusvikira chakakandirwa chinobviswa. Kana chigadzirwa ari mutete-namasvingo, chimiro inotonhodza; kana kugadzirwa kuraswa yakanga zvakakwana muhombe, chill muforoma anogona vakuchidzire pamusoro nokushanda tembiricha, uye akabva ashandisa zvikuru akagovera kutonhora maitiro, saka kuti pamberi inotevera kuraswa chimiro achaita zvakadaro haachandidi.

Die Kudzingwa hakudi zvakaoma uye refu chero nguva basa, kubvisa muitiro kutonhora kutsinga kune achida tembiricha. akavhiyiwa Most kunogona kuitwa nenzira otomatiki Zvikadarowo michina, inova chimwe chinokosha mukana acho, asi chinhu chikuru - kuti simbi muforoma haisi imwe-kure fomu.
