Ntau yam txheej txheem casting tau tsim nyob rau lub sijhawm los ntawm cov chaw tsim khoom thiab cov kws tshawb fawb, txhua tus nrog nws tus yam ntxwv thiab kev siv ntawm covhlau castingskom tau raws li cov kev xav tau ntawm engineering thiab kev pabcuam. Feem ntau hais lus, raws li yog tias cov pwm pwm tuaj yeem rov qab siv tau lossis tsis tau, cov txheej txheem casting tuaj yeem muab faib ua Kev Siv Pwm Casting, Permanent Pwm Casting thiab Composite Pwm Casting. Lub expendable pwm casting kuj muab faib uaxuab zeb casting, plhaub molding,peev castingthiab poob ua npuas ncauj casting, thaum cov pwm tas mus li casting tsuas yog npog lub ntiajteb txawj nqus tuag casting, tsis tshua muaj siab tuag casting thiab siab siab tuag casting.
1. Kev Siv Pwm Casting
Cov pwm tuaj yeem siv tau feem ntau yog ua los ntawm cov xuab zeb, plaster, ceramics, thiab cov ntaub ntawv zoo sib xws. Feem ntau tov nrog ntau yam binders, los yog cov neeg sawv cev sib txuas. Ib hom xuab zeb pwm muaj 90% xuab zeb, 7% av nplaum, thiab 3% dej. Cov ntaub ntawv no yog refractory (tiv taus kub ntawm molten hlau). Tom qab lub casting tau solidified, lub expendable pwm nyob rau hauv cov txheej txheem no yog tawg mus rau tshem tawm qhov kawg hlau castings.
2. Permanent Pwm Casting
Cov pwm mus tas li yog tsim los ntawm cov hlau uas tuav lub zog ntawm qhov kub thiab txias. Lawv siv ntau zaus. Tsim kom cov hlau castings tuaj yeem raug tshem tawm yooj yim thiab pwm tuaj yeem siv dua. Cov pwm mus tas li siv cov khoom siv hluav taws xob zoo dua li cov pwm uas tsis yog xim hlau nthuav dav; Yog li ntawd, solidifying casting yog raug rau ib tug ntau dua tus nqi ntawm txias, uas muaj feem xyuam rau lub microstructure thiab lub grain loj.
3. Composite Pwm Casting
Cov pwm sib xyaw ua ke yog ua los ntawm ob lossis ntau yam khoom sib txawv (xws li xuab zeb, graphite, thiab hlau) sib txuas cov khoom zoo ntawm txhua yam khoom. Cov pwm sib xyaw muaj qhov ruaj khov thiab siv tau thiab siv ntau yam txheej txheem casting los txhim kho pwm lub zog, tswj cov cua txias, thiab txhim kho kev lag luam tag nrho ntawm cov txheej txheem casting.
