Mavharuvhu ekukanda mavharuvhu akagadzirwa nekukanda. Kazhinji, mwero wekumanikidzwa kwemavharuvhu ekukanda wakaderera (senge PN16, PN25, PN40, asi kunewo ane kumanikidzwa kwakanyanya, anogona kusvika 1500Lb, 2500Lb), uye akawanda emavharuvhu avo ari pamusoro peDN50. Mavharuvhu ekukanda mavharuvhu anogadzirwa uye anowanzo shandiswa mumapaipi emhando yepamusoro ane mavharuvhu madiki, kazhinji ari pasi peDN50.
1. Kukanda
1. Kukanda: Inzira yekunyungudutsa simbi kuita mvura inosangana nezvinodiwa uye kuidururira muforoma. Mushure mekutonhodza, kuomesa, uye kuchenesa, kukanda (chikamu kana chisina chinhu) chine chimiro chakatarwa, saizi uye mashandiro anoitwa kunowanikwa. Tekinoroji yekutanga yeindasitiri yekugadzira michina yemazuva ano.
2. Makushe akagadzirwa nesimbi anodhurawo zvishoma, uye anogona kuratidza kushanda zvakanaka kwezvikamu zvine maumbirwo akaomarara, kunyanya zvine maburi emukati akaomarara; panguva imwe chete, anogona kuchinjika zvakanyanya uye ane hunhu hwakanaka hwemakanika.
3. Zvinhu (zvakaita sesimbi, huni, mafuta, zvinhu zvekugadzira, nezvimwewo) uye michina (yakadai semidziyo yesimbi, michina yekusanganisa jecha, michina yekuumba, michina yekugadzira core, michina yekuzunungusa, michina yekupfura, mapurati esimbi akaumbwa, nezvimwewo) zvinodiwa pakugadzira simbi) Zvinonyanya kukosha, uye zvinoburitsa guruva, gasi rinokuvadza uye ruzha uye zvinosvibisa nharaunda.
4. Kukanda imhando yetekinoroji yekupisa simbi iyo vanhu vakambodzidza kare, ine nhoroondo yemakore angangoita 6000.
Muna 3200 BC, kuumbwa kwematatya emhangura kwakaonekwa muMesopotamia. Pakati pezana remakore rechi13 BC nezana remakore rechi10 BC, China yakapinda mumwaka wekugadzirwa kwematatya emhangura.
Unyanzvi hwacho hwasvika padanho repamusoro-soro, senge Simuwu Fangding Ding inorema 875 kg kubva kuShang Dynasty, ndiro yeZenghou Yizun kubva kuWarring States Period, uye girazi rinopenya kubva kuWestern Han Dynasty zvese zvinomiririra kuumbwa kwekare.
Kugadzira zvinhu pakutanga kwakapesvedzerwa zvakanyanya nemidziyo yevhu, uye zvizhinji zvekushandisa pakugadzira zvinhu zvekurima, zvechitendero, uye zvehupenyu.
Ruvara rweunyanzvi rwakasimba. Muna 513 BC, China yakagadzira simbi yekutanga pasi rose (inorema makirogiramu angangoita 270), iyo inowanikwa muzvinyorwa zvakanyorwa.
Munenge muzana remakore rechisere, Europe yakatanga kugadzira michina yesimbi. Mushure meKuchinja Kwemaindasitiri muzana remakore rechi18, michina yesimbi yakapinda munguva itsva yekushandira maindasitiri makuru.
Muzana remakore rechi20, kukura nekukurumidza kwesimbi yekukanda kwakagadzirwa. Simbi yakakandwa ine maronda, simbi inonyungudika, simbi isina ngura ine kabhoni shoma, mhangura yealuminium, silicon yealuminium, uye aluminum-magnesium alloys zvakagadzirwa zvakatevedzana.
Kugadzira zvinhu zvesimbi zvakaita setitanium-based uye nickel-based alloys, uye vakagadzira nzira itsva yekuisa simbi yegrey cast iron. Mushure mema1950, kuumbwa kwejecha rakanyorova kwakakwira kwakaonekwa,
Kugadzira jecha rinoomesa makemikari uye kugadzira core, kugadzira jecha risina simba, kugadzira zvimwe zvinhu zvakakosha, kupfura nepfuti nedzimwe nzira itsva dzekugadzira.
5. Kune mhando dzakawanda dzekugadzira jecha, dzakakamurwa kuita: ①Kugadzira jecha zvakajairika, kusanganisira mhando nhatu dzejecha regirini, jecha rakaoma uye jecha rakaomeswa nemakemikari. ②Kugadzira kwakakosha, zvichienderana nezvinhu zvekugadzira, kunogona kukamurwa kuita kuumba kwakakosha nejecha rezvicherwa zvechisikigo nejecha rematombo sechinhu chikuru chekugadzira (senge kuumba mari, kuumba ivhu, kuumba workshop shell casting, kuumba negative pressure, kuumba solid, kuumba ceramic) nezvimwewo) uye kuumba kwakakosha nesimbi sechinhu chikuru chekugadzira (senge kuumba simbi, kuumba pressure, kuumba continuous casting, kuumba low pressure, kuumba centrifugal, nezvimwewo).
6. Maitiro ekukanda anowanzo sanganisira: ①Kugadzirira maforoma (midziyo inogadzira simbi yemvura kuita maforoma akaoma). Maforoma anogona kukamurwa kuita jecha, simbi, ceramic, ivhu, graphite, nezvimwewo, zvichienderana nehuwandu hwenguva dzekushandiswa. Kune dzinoraswa, dzinogara kwenguva pfupi uye dzinogara kwenguva refu, mhando yegadziriro yeforoma ndiyo chinhu chikuru chinokanganisa mhando yeforoma; ②Kunyunguduka nekudururwa kwesimbi dzakaumbwa, simbi dzakaumbwa (foroma dzinogadzirwa) dzinosanganisira simbi dzakaumbwa, simbi dzakaumbwa uye simbi dzisina ferrous; ③ Kugadzira nekutarisisa maforoma. Kugadzira maforoma kunosanganisira kubvisa mitumbi yekunze pamusoro pemaforoma, kubvisa maporoma anodururwa, kufoshorera maburrs nemadrape seams, pamwe nekurapa kupisa, kuumba, kugadzirisa ngura uye kugadzira rough.

Nortech ndeimwe yemakambani anotungamira mukugadzira mavharuvhu emumaindasitiri muChina ane chitupa chemhando yepamusoro cheISO9001.
