Tuam Tshoj OEM kev cai carbon steel castings los ntawmpoob ciab peev castingthiab CNC precision machining. Muaj qib los ntawm cov pa roj carbon tsawg, nruab nrab carbon steel mus rau siab carbon steel raws li qhov sib txawv specifications.
Cov pa roj carbon alloy yog cov pab pawg ntawm cov hlau-carbon alloy uas tsis tshua muaj lwm yam tshuaj xws li Si, Mn, P thiab S. Raws li qib ntawm cov ntsiab lus carbon, carbon hlau rau casting feem ntau muab faib ua cov pa roj carbon tsawg, nruab nrab carbon steel thiab siab carbon steel. Cov cam khwb cia carbon steels ntawm tag nrho cov teb chaws nyob rau hauv lub ntiaj teb no yog feem ntau muab faib raws li lawv lub zog, thiab coj cov qib yog formulated. Nyob rau tib qhov kub, qhov fluidity ntawm molten steel nrog cov ntsiab lus carbon sib txawv. Vim tias cov hlau uas muaj cov ntsiab lus carbon sib txawv muaj qhov sib txawv ntawm kev loj hlob hauv dendrites. Qhov siab dua qhov kub ntawm qhov chaw crystallization (qhov kub qhov sib txawv ntawm cov kua kab thiab cov kab solidus), qhov ntau tsim cov dendritic crystals ntawm cov pa roj carbon steel, uas yog, qhov fluidity ntawm cov hlau molten yuav ua rau cov hlau tsis zoo. muaj peev xwm ntawm cov hlau molten los sau pwm.
Hais txog cov tshuaj muaj pes tsawg leeg ntawm carbon steel, tshwj tsis yog rau phosphorus thiab sulfur, tsis muaj kev txwv lossis tsuas yog txwv sab saud ntawm lwm cov tshuaj. Nyob rau hauv cov ntaub ntawv saum toj no, cov tshuaj muaj pes tsawg leeg ntawm cam khwb cia carbon steel yog txiav txim los ntawm lub foundry raws li qhov yuav tsum tau txhua yam khoom.
Cov kev kho cua sov ntawmcarbon hlau castingsfeem ntau yog annealing, normalizing lossis normalizing + tempering. Rau qee qhov siab carbon steel castings, quenching thiab tempering tuaj yeem siv tau, uas yog, quenching + kub tempering, thiaj li los txhim kho cov khoom siv kho txhua yam ntawm carbon steel castings. Me carbon steel castings tuaj yeem ncaj qha quenched thiab tempered los ntawm lub xeev li-cam khwb cia. Rau loj-scale los yog complex-shaped carbon steel castings, nws yog tsim nyog los ua quenching thiab tempering kev kho mob tom qab normalizing kev kho mob.
Qhov zoo ntawm Investment Casting:
✔ Zoo heev thiab du nto tiav
✔ Tight dimensional kam rau ua.
✔ Cov duab sib txawv thiab sib txawv nrog kev tsim qauv yooj yim
✔ Muaj peev xwm nrum cov phab ntsa nyias yog li qhov sib zog ua haujlwm
✔ Kev xaiv dav ntawm cov hlau cam thiab alloys (ferrous thiab non-ferrous)
✔ Draft tsis tas yuav tsum muaj nyob rau hauv cov pwm tsim.
✔ Txo qhov xav tautheem nrab machining.
✔ Cov khoom siv tsawg tsawg.

Cov kauj ruam ntawm kev nqis peev Casting txheej txheem:
Thaum lub sij hawm peev casting txheej txheem, ib tug siv quav ciab qauv yog coated nrog ib tug ceramic khoom, uas, thaum hardened, txais lub internal geometry ntawm qhov xav tau casting. Feem ntau, ntau qhov chaw raug nrum ua ke rau kev ua haujlwm siab los ntawm kev txuas ib tus qauv siv quav ciab rau hauv nruab nrab cov quav ciab hu ua sprue. Cov wax melted tawm ntawm tus qauv - uas yog vim li cas nws tseem hu ua txoj kev poob ciab - thiab molten hlau yog poured rau hauv kab noj hniav. Thaum cov hlau solidifies, lub ceramic pwm yog shaken tawm, tawm hauv lub ze net zoo li qhov xav tau casting, ua raws li kev ua tiav, kuaj thiab ntim.
