Keeb kwm keeb kwm ntawm peev casting: Txoj kev poob ciab nyob rau hauv kuv lub teb chaws originated nyob rau hauv lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg ntawm qhov tseeb. Lub bronze txwv tsis pub los ntawm lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg unearthed los ntawm Chu Tomb No. 2 nyob rau hauv Xichuanxia Tuam Tsev, Henan xeev yog lub earliest paub ploj casting. Plaub sab thiab ob sab ntawm no bronze txiav npluav yog dai kom zoo nkauj nrog openwork huab qauv. Muaj kaum ob tug tsiaj nyaum sawv ntsug nyob ib ncig, thiab muaj kaum ob tug tsiaj nyaum sawv ntsug hauv qab lub cev. Cov qauv openwork yog qhov nyuaj thiab hloov tau, thiab cov tsos yog gorgeous thiab solemn, xav txog tias txoj kev poob ciab hauv kuv lub teb chaws kuj paub tab nyob rau nruab nrab lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg. Tom qab Tsov Rog Xeev Lub Sijhawm, Qin thiab Han Dynasties, txoj kev ploj ploj tau nrov dua, tshwj xeeb tshaj yog nyob rau lub sijhawm ntawm Sui thiab Tang Dynasties mus rau Ming thiab Qing Dynasties, feem ntau ntawm cov khoom siv tooj liab tau raug pov los ntawm txoj kev ploj lawm.
Qhov txiaj ntsig loj tshaj plaws ntawm kev nqis peev casting yog vim qhov tseeb qhov tseeb thiab qhov chaw tiav ntawm kev nqis peev castings, kev ua haujlwm tuaj yeem raug txo qis, tab sis tsuas yog ib qho me me ntawm kev siv tshuab tuaj yeem tso rau ntawm qhov chaw uas yuav tsum tau siab dua, thiab txawm tias qee qhov castings xwb. Tawm kev sib tsoo, polishing nyiaj pub dawb, tuaj yeem siv yam tsis muaj machining. Nws tuaj yeem pom tau tias kev siv peev casting txoj kev tuaj yeem txuag tau ntau ntawm cov cuab yeej siv tshuab thiab lub sijhawm ua haujlwm, thiab txuag cov khoom siv hlau zoo heev.
Lwm qhov kom zoo dua ntawm txoj kev peev casting yog tias nws tuaj yeem nrum complex castings ntawm ntau yam alloys, tshwj xeeb tshaj yog superalloy castings. Piv txwv li, cov hniav ntawm lub dav hlau lub cav muaj ib tug streamlined qauv thiab ib tug puab kab noj hniav kom txias, uas yuav tsis tau tsim los ntawm machining. Cov txheej txheem casting peev tsis tsuas yog ua tiav ntau lawm thiab xyuas kom meej qhov sib xws ntawm castings, tab sis kuj zam qhov kev ntxhov siab ntawm cov riam seem tom qab machining.
