Casting yog txheej txheem ntawm melting hlau rau hauv cov kua uas ua tau raws li tej yam yuav tsum tau thiab pouring rau hauv pwm. Tom qab txias, solidification, thiab tu kho, ib tug casting nrog predetermined zoo, loj, thiab kev ua tau zoo yog tau. Casting blanks, vim lawv nyob ze formability, ua tiav lub hom phiaj ntawm kev zam kev siv tshuab lossis ua haujlwm tsawg, txo cov nqi thiab qee qhov txo lub sijhawm ntau lawm. Casting yog ib qho ntawm cov txheej txheem yooj yim hauv kev tsim khoom siv niaj hnub no.
Cov yam ntxwv ntawm txheej txheem:
1. Nws tuaj yeem tsim qhov chaw nrog txhua yam duab, tshwj xeeb tshaj yog cov uas muaj cov kab noj hniav zoo nkauj.
2. Muaj zog adaptability, unrestricted alloy hom, thiab yuav luag unlimited casting loj.
3. Cov khoom siv dav dav, cov khoom pov tseg tuaj yeem rov qab tau, thiab cov cuab yeej siv peev nyiaj tsawg.
4. Cov khib nyiab siab, qhov chaw tsis zoo, thiab kev ua haujlwm tsis zoo.
Txheej txheem khiav: kua hlau → filling → solidification shrinkage → casting
Cov cam khwb cia hlau muaj xws li tooj liab, hlau, txhuas, tin, txhuas, thiab lwm yam. Cov ntaub ntawv siv rau kev ua haujlwm zoo tib yam yog cov xuab zeb nyoos, av nplaum, iav dej, resin, thiab lwm yam khoom siv. Cov pwm tshwj xeeb muaj xws li peev casting, poob ua npuas ncauj casting, hlau pwm casting, ceramic pwm casting, thiab lwm yam.
Casting Classification:
1. Xuab zeb casting
2. Kev nqis peev casting
3. Siab casting
4. Tsis tshua muaj siab casting
5. Centrifugal casting
6. Hlau pwm casting
7. Nqus casting
8. Nyem casting
9. Poob ua npuas ncauj casting
10. Nruam casting
Qhov zoo ntawm casting:
1. Nws tuaj yeem ua rau hauv cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob
2. dav adaptability
3. Casting tuaj yeem siv ncaj qha siv cov khoom siv khib nyiab thiab cov chips, nrog cov nqi qis dua
4. Qhov loj thiab zoo ntawm castings yog yuav luag tsis txwv
5. Cov duab thiab qhov loj ntawm cov casting yog ze rau ntawm qhov chaw, yog li txo qhov kev ua haujlwm ntawm machining thiab txuag tau ntau cov ntaub ntawv hlau.
Qhov tsis zoo:
1. Muaj ntau cov txheej txheem ntau lawm, cov txheej txheem yog qhov nyuaj rau kev tswj, thiab castings yog qhov ua rau muaj qhov tsis xws luag
2. Tsis zoo dimensional uniformity thiab tsawg seem raug ntawm castings
3.Piv rau forgings ntawm tib cov duab thiab loj, qhov zoo ntawm infrared carbon sulfur meter castings yog tsis zoo, thiab lub peev xwm load-bearing tsis zoo li forgings.
4. Kev ua haujlwm tsis zoo, qhov kub thiab txias, hmoov av siab, thiab kev siv zog ua haujlwm siab
