Feem ntau, ib puag ncig rautitanium cevkho vuam los ntawm cov tuam ntxhab tsis tuaj yeem muaj cua ntws, thiab lwm yam zoo ib yam li cov hauv lub thawv vuam. Txawm li cas los xij, tshwj xeeb yuav tsum tau them rau:
(1) Qhov chaw kho vuam yuav tsum tsis txhob loj dhau. Qhov ntws ntawm nitrogen thaum kho vuam yuav tsum loj dua, thiab cov roj tsis tuaj yeem nres hauv nruab nrab;
(2) Tom qab kho qhov vuam, txuas ntxiv siv cov nitrogen rau kev tiv thaiv kom txog thaum thaj chaw txias;
(3) Rau qee qhov tshwj xeeb castings, xws li complex nyias-phab ntsa castings, txhawm rau tiv thaiv oxidation ntawm lub nraub qaum ntawm qhov chaw kho vuam, argon tuaj yeem tshuab rau sab nraub qaum kom txog thaum cov castings txias;
(4) Kev kho vuam cov neeg ua haujlwm yuav tsum muaj cov txheej txheem siab.

Yuav kom tau txaistitanium cevcastings nrog zoo kho vuam zoo, cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau hauv kev kho vuam txheej txheem:
(1) Qhov saum npoo ntawm cov castings rau kev kho vuam yuav tsum tau muab ntxuav thiab qhuav, thiab cov castings tsis raug tso cai los ntawm tes ncaj qha ua ntej muab tso rau hauv lub thawv vuam.
(2) Thaum lub sij hawm kho vuam ntawm titanium raj, luv luv Circuit Court ntawm tungsten electrode thiab kho vuam vuam yuav tsum nruj me ntsis txwv tsis pub, uas ua rau lub puas ntawm cov tungsten electrode thiab cov tungsten inclusion nyob rau hauv lub vuam sib koom.
(3) Thaum lub cheeb tsam thiab qhov tob ntawm qhov kho vuam qhov chaw yog qhov loj, nws yuav tsum tau welded nyob rau hauv ob peb txheej nyob deb, thiab welding ntawm txheej tom ntej no yuav tsum tau nqa tawm tsuas yog tom qab cov txheej txheem dhau los yog txias tag. Nws yog kiag li tsis tso cai rau weld nyob rau hauv ib lub sij hawm los tiv thaiv lub deformation ntawm lub casting.
(4) Thaum kawg ntawm kev kho vuam, qhov tam sim no yuav tsum tau maj mam txo kom txo qhov melting tsam. Yog li ntawd, nws raug nquahu kom siv cov mem tes tam sim no txhawm rau tiv thaiv cov ntse arc tawg thiab tawg.
(5) Tom qab kho vuam, cov castings yuav tsum tau tso cai rau txias rau hauv lub thawv rau ib lub sij hawm ua ntej unpacking thiab tshem tawm cov castings los tiv thaiv tej tawg los yog deformation nyob rau hauv lub vuam cheeb tsam ntawm lub castings tshwm sim los ntawm ceev ceev txias; Qhov ntev ntawm lub sijhawm txias yog nyob ntawm phab ntsa thickness ntawm cov casting, feem ntau yog 15-30mm.
(6) Titanium yeeb nkabcastings yuav tsum tau annealed los yog kub isostatic nias nyob rau hauv lub sij hawm tom qab kho welding, thiab yuav tsum tsis txhob tso tseg ntev heev, feem ntau tsis ntau tshaj 5 hnub.
(7) Tus naj npawb ntawm kev kho vuam yuav tsum tsis pub tshaj cov kev cai ntawm cov ntaub ntawv tseem ceeb.
