Tsis yog -welded Molybdenum Crucible

                                                            Seamless / Tsis yog -Welded Molybdenum Crucible

Nws txhais tau tias molybdenum crucible yog tsim los ntawm Integral-molded=Tsis muaj vuam seams, tag nrho molybdenum billet yog molded ncaj qha.

1. Forging + Machining (Forging ib qho tseem ceeb crucible, feem ntau haum rau me me - mus rau - nruab nrab tuab - phab ntsa crucibles)

Cov txheej txheem ntws: Molybdenum hmoov nias thiab sintering → Forging molybdenum pas nrig billet → CNC tshuab dhos thiab tig mus rau daim ntawv → Fine txiav, tu thiab tshuaj xyuas

Features: Density close to theoretical density 10.2g/cm³, dense grains, optimal high-temperature creep resistance; haum rau semiconductor thiab precious hlau melting; haum rau crucibles nrog ib txoj kab uas hla ntawm Tsawg dua los yog sib npaug li 100mm.

2. Thermal spinning molding (tsim rau nyias -walled integral crucibles)

Cov txheej txheem khiav: Rolling molybdenum phaj billet → High - kub cua sov ntawm 600-1000 degree, thermal spinning los tsim lub crucible plhaub → Tempering kom tshem tawm kev ntxhov siab → Machining thiab xov

Nta: Nyias phab ntsa, niaj hnub phab ntsa thickness, zoo thermal conductivity; haum rau rotary crucibles nrog ib txoj kab uas hla ntawm 50-300mm; molybdenum yog nkig heev nyob rau hauv chav tsev kub, yuav tsum tau kub spinning.

3. hmoov metallurgy isostatic nias thiab sintering rau ib qho molding (tsuas yog siv rau kev tsim loj -sized integral crucibles)

Txheej txheem ntws: Molybdenum hmoov isostatic nias rau hauv crucible billet → High-kub nruab nrab- zaus sintering → Sab hauv thiab sab nrauv phab ntsa machining.

Nta: Muaj peev xwm ua tau loj -sized crucibles; Qhov ceev me ntsis qis dua qhov forged (9.6-9.9 g / cm³), tus nqi ua tau zoo dua li forging, tsis muaj vuam seams.

1. Molybdenum yog nkig heev ntawm chav tsev kub: Zoo li ceramics, nws yog nkig heev. Spinning thiab forging yuav tsum tau nqa tawm ntawm qhov kub thiab txias; txawm tias qhov hloov pauv me ntsis ntawm qhov kub thiab txias, kev sib hloov ceev, los yog pub ncaj qha ua rau tawg thiab tawg, ua rau muaj qhov tsis muaj txiaj ntsig.

2. Cov khoom poob hauv forging machining yog loj: Forging ib qho tseem ceeb crucible, hollowing tawm ib tug molybdenum pas nrig thiab tig mus rau hauv ib tug crucible, cov khoom siv tus nqi tsuas yog 20-40%, thiab ib tug loj npaum li cas ntawm kim molybdenum hlau hloov mus rau hauv seem.

3. Qhov siab tshaj plaws rau cov txheej txheem spinning: qhov kub thiab txias yog nqaim, lub qhov rais parameter rau spinning yog me me; uniformity ntawm phab ntsa thickness thiab hauv qab ces kaum txoj hauj lwm yog prone mus rau micro- tawg, yuav tsum tau cov khoom siab thiab cov txheej txheem kev paub; tsis muaj ntau lub tuam txhab tsim khoom hauv tsev uas tuaj yeem ua tiav cov khoom lag luam ruaj khov.

4. Kev tswj tsis tau yooj yim ntawm sintering shrinkage rau ib qho molding: Sintering shrinkage yog 15-20%, kev tswj tsis zoo ntawm cov nyiaj them poob haujlwm thiab segmented cua sov thiab txias, ua rau cov khoom lag luam tuaj yeem tawg thiab deformation.

5. Kev tshem tawm kev ntxhov siab thoob plaws hauv cov txheej txheem: Tom qab txhua txheej txheem molding, nws yuav tsum tau nqus cov annealed kom tshem tawm cov kev ntxhov siab seem; txwv tsis pub, micro- tawg ntawm sab hauv yuav nthuav dav hauv siab - qhov kub thiab txias, ua rau cov khoom lag luam ua tsis tiav.

Cov teeb meem ntawm welded molybdenum crucibles feem ntau yog nyob rau hauv lub vuam zoo ntawm weld seam; Cov khoom siv raw yog dov molybdenum phaj, molding yog yooj yim, thiab tsis muaj teeb meem loj ntawm cov yas deformation.
 

1. Cov khoom siv tsawg tsawg

Forging thiab machining ib qho tseem ceeb crucible, hollowing tawm ib tug khoom molybdenum pas nrig, ib tug loj npaum li cas ntawm molybdenum cov ntaub ntawv ua seem; Thaum rau welded crucibles, dov molybdenum daim hlau yog siv, thiab cov khoom raug txiav, dov, thiab tsim, nrog rau cov khoom siv ntawm 75-85%, uas ua rau muaj qhov sib txawv loj ntawm cov khoom poob.

2. Cov txheej txheem nyuaj, cov cuab yeej siv siab, cov khoom siv ntev ntev
Thermal spinning yuav tsum tau tshwj xeeb high -kub spinning khoom; forging yuav tsum tau loj forging tshuab, ntau cua sov, sib sau, thiab annealing txheej txheem; welding tsuas yog muaj cov ntawv hlau + lub tshuab nqus tsev vacuum, cov txheej txheem tsawg dua, thiab kev tsim khoom sai.

3. Tus nqi qis dua

Kev pheej hmoo ntawm kev tawg thiab khawb thaum lub sij hawm forging txheej txheem yog siab; rau vuam, ntev li ntev raws li cov txheej txheem vuam yog ruaj khov, cov seem seem yog qis dua ib qho molding.

4. Kev tshaj tawm siab dua - tus nqi tshuaj xyuas

Cov khoom tseem ceeb yuav tsum tau kuaj ultrasonic los kuaj xyuas cov micro- tawg; rau welded pieces, tsuas yog cov weld seam yuav tsum tau soj ntsuam.

Kev lag luam tus nqi siv: Rau tib qhov kev qhia tshwj xeeb thiab phab ntsa tuab, tus nqi ntawm seamless molybdenum crucibles yam tsis muaj vuam yog kwv yees li 2-3 npaug ntawm hom welded.
