Poob lawm ciab casting - yuav ua li cas no yog lub sij hawm-siv

Cov txheej txheem uas cov casting yog tau siv cov free hlau casting txheej txheem uas yog nyob rau hauv ib tug molten lub xeev, mus rau hauv tshwj xeeb nrhiav, yog hu ua tus "peev casting".

Tus heev txheej txheem ntawm technology yog heev. Koj thawj yuav tsum tau tsim ib tug tshwj xeeb tswv qauv, uas yog ib yam ntawm cov tsab uas yuav tau melted, t. E. Yuav pab raws li ib tug siv taw tes nyob rau hauv cov kev taw qhia uas yuav coj txoj kev loj hlob.

Kom tus tswv qauv, cov tub txawg feem ntau siv cov ntaub ntawv xws li ntoo thiab plaster. Lub luag hauj lwm ua qauv yuav tuaj rau pem hauv ntej thiab twb ua nyob rau hauv lwm tsob nroj khoom. Cov kauj ruam tom ntej - cov creation ntawm matrices thiab molds. Lawv cia li yuav tsum nqa tawm txhaj tshuaj molding.

Pwm no feem ntau yog tau sau nrog cov tallow los yog ciab, vim hais tias cov tshuaj muaj theem ntawm plasticity, uas tso cai rau cov qhov tso zis kom tau tag nrho cov xaiv ntawm cov ntaub ntawv.

Tom ntej no, peb yuav tsum tau yaj nyob rau hauv daim ntawv ntawm ib tug tshiab chamber - ua hauj lwm. Nws yog tau los ntawm cov qauv ntawm cov melting. Uas yog vim li cas cov txheej txheem no hu ua "poob-ciab casting."

Casting nws tus kheej nyob rau tib lub sij hawm nyob rau hauv lub plhaub tsim los ntawm ib tug tshwj xeeb pes tsawg leeg muaj peev xwm sawv ntawm tiv heev kub, uas qauv yog ua tib zoo ua ntej sau txoj kev. Raws li cov solidification kawg neeg ua hauj lwm rhuav daim ntawv.

Nyob rau hauv cov pa peev casting siv quav ciab los stearin yog muab tshem tawm nrog dej kub. Zoo li uas yog tau ua los ntawm tus txheej txheem no, ces tus calcination kauj ruam yog sequentially thiab pouring molten hlau. Calcining lub plhaub yog rhuab mus kub feem ntau tshaj 900 degrees Celsius, uas tso cai rau kom daws tau qhov teeb meem ntawm tau txais cov kev organic tebchaw nyob rau hauv muaj pes tsawg leeg, yog tias uncorrected, uas tej zaum yuav txo qhov zoo ntawm cov khoom tso zis.

Nyias, nws yog sau hais tias lub plhaub yuav tsum tau ua noj mus rau hauv tus account lub kuj mus rau ib tug ntau yam sib txawv ntawm cov tshuaj tebchaw.

Uas peev casting tso cai rau koj mus muab pov rau hauv lub tso zis, uas nws loj yuav ntsuas ib tug ob peb grams, tab sis ua tau - li ntawm ob peb tons. Lub thickness ntawm lub sab phab ntsa ntawm cov khoom yuav ua tau raws li me ntsis li ib nrab ntawm ib millimeter, uas muaj raws li tag nrho cov txais thoob ntiaj teb cov qauv.

Nrog lub tswvyim ntawm casting, peev casting, yog li ntawd, nws yog ncaj qha mus txog rau lub tswvyim ntawm precision casting. Nws yog yuav luag tag zoo tib yam castings manufactures ob nyob rau hauv loj thiab nyob rau hauv lub cev.

Tus txheej txheem ntawm kev nqis peev casting yog heev nrov ob nyob rau hauv Russia thiab nyob rau hauv lub so ntawm lub ntiaj teb no. Muaj txawm advanced chaw cia koj ua txhaj molding.

Mus nqa tawm lub molding txheej txheem ntawm peev casting yuav tsum tau ib tug tag nrho co txawv kiag li lawm thiab sib. Technological txheej txheem hauv qhuav thiab tom ntej casting nrhiav ua los ntawm tej hub, kom qhuav lawv, lub refractory txheej pes tsawg leeg thiab lub melting stearin, tu castings tau. Tag nrho cov saum toj no-piav cov txheej txheem yog theej txoj thiab laborious.
