Silica solicoing, tseem hu ua kev nqis peev casting, yog qhov precision casting txheej txheem siv dav hauv kev lag luam tsim. Nws yog qhov tshwj xeeb tsim rau kev tsim cov hlau seem nrog cov duab sib xyaw, cov qauv siab thiab cov khoom siab zoo.
Ua Wax Pwm
Ua ntej, siv cov peev txheej txhaj tshuaj moulding thev naus laus zis, ciab yog txhaj rau cov pwm kom tsim cov mould wax uas yog qhov zoo ib yam li cov hlau kawg. Kauj ruam no yog lub hauv paus ntawm tag nrho cov txheej txheem.
Lam ntoo
Tom ntej no, ntau cov quav ciab ntau dua ua ke ua ke los ua ib qho "pwm ntoo" yog li ntau yam khoom siv tuaj yeem tsim tawm hauv ib zaug. Cov kauj ruam no txhim kho kev tsim khoom.
Txheej (Plhaub Ua)
Cov pwm ntoo yog raus hauv silica sol (ib qhov kub-ruaj khov ua daws) thiab sprinkled nrog zirconium oxide lossis aluminium oxide hmoov. Rov ua cov txheej thiab hmoov ntau rau ob peb zaug los ua lub plhaub plhaub.
Dewaxing
Cov ciab moulle coated nrog lub plhaub yog rhuab rau ib qho kub thiab txias me me, thiab cov quav ciab pwm melts thiab ntws tawm, tawm hauv lub plhaub khoob. Cov kauj ruam no yog hu ua cov txheej txheem Dewaxing.
Ci lub plhaub
Lub plhaub tom qab dewaxing yuav tsum tau ci ntawm qhov kub kom ua kom lub zog ntawm lub khauj khaum kom nws tuaj yeem tiv thaiv cov hlau siab molten ntawm cov txheej txheem casting.
Hliv hlau
Ncuav molten hlau (xws li stainless hlau (xws li stainless hlau, carbon hlau, tooj liab alloy, thiab lwm yam) rau hauv lub plhaub. Cov kua kub hlau hnyav yuav sau cov kab noj hniav ntawm lub khauj khaum los ua cov duab kawg ntawm cov hlau.
Plhaub thiab tu
Tom qab cov hlau txias thiab solidifies, khob lub plhaub kom ua rau lub ntsej muag. Tom qab ntawd ua raws li kev kho mob uas tsim nyog, xws li txiav lub rooj vag, sib tsoo, kho cua sov, thiab lwm yam.
Soj ntsuam thiab xov
Tom qab lub casting undergoes nruj ua tau zoo kev kuaj xyuas (xws li kev soj ntsuam kom meej, thiab sib zog ua kom meej tias cov khoom kawg tau raws li cov qauv kev cai.
