Raws li kev lag luam xws li kev tsim khoom, kev tsim tsheb, kev siv hluav taws xob, thiab cov khoom siv tsim kho qhov chaw xav tau ntau dua ntawm kev ua tau zoo ntawm cov khoom siv, xaiv txoj cai hlau casting tau dhau los ua qhov tseem ceeb. Qhov tsim nyog casting yuav tsum ua tau raws li qhov yuav tsum tau muaj thiab cov qauv tsim thaum tseem muab cov khoom siv uas haum rau qhov chaw ua haujlwm tiag tiag. Kev xaiv ua tib zoo tuaj yeem txhim kho kev ntseeg tau ntawm cov cuab yeej siv thiab pab txo qis - lub sijhawm tu thiab hloov cov nqi.
Kev xaiv cov khoom siv yog ib qho tseem ceeb tshaj plaws thaum ntsuas cov hlau casting. Cov khoom siv casting muaj xws li cam khwb cia hlau, cam khwb cia hlau, aluminium alloys, thiab tooj liab alloys, txhua tus muab cov yam ntxwv sib txawv. cam khwb cia hlau muaj nuj nqis rau nws hnav tsis kam thiab kev co -damping zog thiab feem ntau yog siv rau lub hauv paus tshuab, twj tso kua mis vaj tse, thiab cov khoom enclosures. Cam khwb cia hlau muab lub zog siab thiab toughness, ua rau nws haum rau cov khoom raug hnyav los yog cuam tshuam. Aluminium alloys muab qhov hnyav qis thiab zoo thermal conductivity, ua rau lawv txaus nyiam rau kev siv tsheb thiab hnav. Copper alloys feem ntau xaiv rau lawv cov hluav taws xob conductivity, thermal kev ua tau zoo, thiab corrosion kuj. Yog li ntawd, cov khoom siv yuav tsum raug xaiv raws li cov yam ntxwv xws li kev khiav hauj lwm kub, cov khoom siv hluav taws xob, thiab raug rau cov kua dej los yog qhov chaw corrosive.
Cheebtsam geometry yuav tsum tau ua tib zoo soj ntsuam. Castings nrog cov duab nyuaj, nyias ntu, txhawb cov tav, lossis cov kab noj hniav sab hauv yuav tsum muaj cov txheej txheem tsim khoom muaj peev xwm ua tau cov yam ntxwv tsis tu ncua. Ib qhov zoo- tsim qauv tuaj yeem txo qhov kev pheej hmoo ntawm kev ua haujlwm tsis zoo thaum ua haujlwm tom qab thiab kev sib dhos ua haujlwm tau zoo dua.
Cov txheej txheem tsim khoom thiab kev tswj kom zoo yog qhov tseem ceeb sib npaug. Thaum ntsuam xyuas tus neeg xa khoom casting, cov tuam txhab lag luam yuav tsum xav txog lub tuam txhab muaj peev xwm hauv melting, pouring, txias, kho cua sov, thiab machining. Dimensional raug, qhov chaw nyob, thiab kev ncaj ncees ntawm cov khoom siv sab hauv yuav tsum raug txheeb xyuas raws li qhov yuav tsum tau ua ntawm daim ntawv thov. Rau cov khoom tseem ceeb uas raug rau cov khoom hnyav lossis kev ua haujlwm tas mus li, kev tshuaj xyuas thiab kev sim ntxiv yuav tsim nyog.
Tus neeg muag khoom nws tus kheej yog lwm qhov kev txiav txim siab tseem ceeb. Kev muaj peev xwm ntau lawm, kev tswj kom zoo, kev cia siab rau kev xa khoom, kev txhawb nqa, thiab tom qab- kev muag khoom tuaj yeem cuam tshuam tag nrho cov nqi ntawm cov casting. Cov kws tshaj lij kev lag luam taw qhia tias tus nqi qis tshaj yuav tsis tas sawv cev rau qhov kev xaiv zoo tshaj plaws. Ib txoj hauv kev zoo dua yog qhov sib npaug ntawm kev ua tau zoo, qhov zoo, tus nqi, thiab kev cia siab rau lub neej.
Raws li kev tsim khoom txuas ntxiv mus rau qhov kev ua tau zoo dua thiab kev ua tau zoo dua, kev xaiv hlau casting tau nce zuj zus ntxiv rau tag nrho tus nqi ntau dua li tus neeg tshwj xeeb. Los ntawm kev txhais kom meej cov kev xav tau ntawm kev khiav hauj lwm, xaiv cov khoom tsim nyog thiab cov txheej txheem tsim khoom, thiab tsim kom muaj kev ntsuam xyuas kev ua tau zoo, cov tuam txhab lag luam tuaj yeem muaj cov khoom siv txhim khu kev qha ntau dua thiab txhawb kev ruaj khov, ntev - cov cuab yeej siv tau zoo.
