Tab sis nws yuav tsum tau sau tseg:
1. Qhov chaw kho vuam yuav tsum tsis txhob loj dhau, qhov ntws ntawm ammonia roj yuav tsum loj dua thaum lub sij hawm kho vuam txheej txheem, thiab cov roj yuav tsum tsis txhob nres nyob rau hauv nruab nrab;
2. Tom qab kev kho vuam tiav lawm, kev tiv thaiv roj ammonia yuav tsum txuas ntxiv mus kom txog rau thaum thaj chaw txias:
3. Rau qee qhov tshwj xeeb castings, xws li complex nyias-walled castings, txhawm rau kom tsis txhob oxidation ntawm sab nraub qaum ntawm qhov chaw kho vuam, xenon roj tuaj yeem raug tshuab mus rau sab nraub qaum kom txog thaum lub casting txias;
4. Kev kho cov neeg ua haujlwm vuam yuav tsum muaj kev ua haujlwm siab.
Txhawm rau kom tau txais titanium raj castings nrog kev kho vuam zoo, cov ntsiab lus hauv qab no yuav tsum tau sau tseg thaum lub sijhawm kho vuam txheej txheem:
1. Qhov saum npoo ntawm cov castings rau kev kho vuam yuav tsum huv thiab qhuav. Cov castings tsis raug tso cai kov ncaj qha los ntawm tes ua ntej muab tso rau hauv lub thawv vuam.
2. Thaum kho cov kav dej titanium thiab titanium coils, ceev faj kom tsis txhob luv luv ntawm tungsten electrode thiab kho vuam qhov chaw, uas yuav ua rau cov tungsten electrode tawg thiab ua rau tungsten inclusions nyob rau hauv cov pob qij txha.
3. Thaum qhov chaw thiab qhov tob ntawm qhov chaw kho vuam yog qhov loj, qhov vuam yuav tsum tau nqa tawm hauv ntau qhov chaw nyob deb, thiab txheej tom ntej yuav tsum tau welded tom qab txheej txheej dhau los tau txias. Nws tsis raug tso cai rau welded hauv ib qho mus kom tsis txhob deformation ntawm casting.
4. Thaum kawg ntawm kev kho vuam, qhov tam sim no yuav tsum tau maj mam txo kom nqaim thaj tsam melting. Yog li ntawd, nws raug nquahu kom siv cov mem tes tam sim no kom tsis txhob nrawm arc tawg thiab ua rau tawg.
5. Tom qab kev kho vuam tiav lawm, lub casting yuav tsum tau tso cai rau txias rau hauv lub thawv rau ib lub sij hawm ua ntej unpacking lub casting kom tsis txhob tawg los yog deformation nyob rau hauv lub vuam cheeb tsam ntawm lub casting vim txias ceev; Qhov ntev ntawm lub sijhawm txias yog nyob ntawm phab ntsa thickness ntawm cov casting, feem ntau yog 15-30mm.
6. Tom qab kho vuam ntawm titanium kav thiab titanium coil castings, lawv yuav tsum tau annealed los yog kub isostatically nias nyob rau hauv lub sij hawm. Lawv yuav tsum tsis txhob cia lawv nyob ib leeg ntev heev, feem ntau tsis tshaj 5 hnub.
