Zirconium tube pas nrig yog cov khoom siv tubular hlau ua los ntawm cov hlau zirconium thiab lwm yam hlau. Vim muaj cov khoom siv hluav taws xob zoo heev thiab kev tiv thaiv corrosion ntawm zirconium, zirconium alloy tube rods feem ntau siv rau hauv cov khoom siv hluav taws xob nuclear thiab cov qauv sab hauv ntawm cov dej-txias reactors thiab yog cov ntaub ntawv tseem ceeb nuclear. Ntshiab zirconium tube rods yog siv los tsim cov khoom siv tshuaj, vim tias lawv kim heev thiab tsis siv ntau ntau. Cov tshuaj lom neeg muaj pes tsawg leeg thiab kev siv feem ntau siv zirconium tube rods tau pom nyob rau hauv lub rooj, ntawm cov zirconium-tin alloy tube rods yog siv ntau dua.
Cov yam ntxwv txheej txheem
(1) Zirconium muaj zog affinity nrog roj. Nws pib hnov mob nrog oxygen, hydrogen, thiab nitrogen ntawm txog 200, 300, thiab 400 degree feem. Cov tshuaj tiv thaiv yog ceev ceev ntawm qhov kub thiab txias, yog li casting thiab kho cua sov yuav tsum tau ua nyob rau hauv lub tshuab nqus tsev rauv. Thaum ua cov txheej txheem thermal hauv huab cua, kev tiv thaiv kom zoo yuav tsum tau ua thiab lub sijhawm ua haujlwm ntawm qhov kub thiab txias yuav tsum luv luv.
(2) Kev sib txhuam coefficient ntawm zirconium thiab pwm yog siab thiab nws yooj yim rau kev ua raws li cov pwm pwm; Cov nyhuv thermal ntawm cov yas deformation yog qhov tseem ceeb, thiab cov txheej txheem lubrication zoo yuav tsum tau ua thaum ua.
(3) Cov txheej txheem ua tiav muaj qhov cuam tshuam rau kev ua haujlwm ntawm cov khoom. Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev tswj cov kev ua haujlwm txias thiab kev kho cua sov ua ntej cov khoom tiav kom tau raws li cov kev xav tau ntawm kev siv.
(4) Qhov tseeb qhov tseeb thiab qhov zoo ntawm cov kav dej thiab cov kav dej yog qhov xav tau heev. Yog li ntawd, cov txheej txheem cov cuab yeej yuav tsum muaj qhov raug zoo, thiab cov cuab yeej thiab pwm tsim thiab tsim khoom yuav tsum tau ua kom zoo thiab tsim nyog.

Vuam kev ua tau zoo tsom xam
Cov ntaub ntawv Zirconium yog siv los tiv thaiv corrosion hauv kev lag luam tshuaj. Lawv tseem nyob rau hauv lawv cov me nyuam mos nyob rau hauv kuv lub teb chaws thiab tsis muaj kev paub welding. Raws li cov khoom siv tshuaj tiv thaiv corrosion, titanium tau dav siv. Raws li cov ntaub ntawv tseem ceeb, titanium muaj qhov zoo weldability thiab me me nyiam ua cov kab nrib pleb.
Nws tuaj yeem welded los ntawm ntau txoj kev, feem ntau yog siv roj tungsten arc vuam (GTAW). , argon arc vuam (GMAW), plasma arc vuam (PAW), thiab lub tshuab nqus tsev electron beam vuam yog siv los vuam hlau. Vuam feem ntau tsis tas yuav preheating. Preheating tuaj yeem siv rau hauv qhov chaw uas muaj qhov kub thiab txias los yog cov av noo siab ua ib qho kev pab cuam ntawm kev tshem tawm cov av noo. Thaum lub sij hawm vuam, cov cheeb tsam uas kub siab tshaj 300 degree (xws li welds, tshav kub-tshuaj tiv thaiv cheeb tsam, lub hauv paus hlau, thiab sab nraub qaum ntawm vuam) yuav tsum tau tiv thaiv los ntawm argon.
Thaum zirconium siab tshaj 590 degree, nws yog rhiab heev rau lub brittleness ntawm 02, N2, thiab H2. Yog li ntawd, qhov vuam ntawm cov hlau no yuav tsum tau tiv thaiv kom tsis txhob muaj kuab paug atmospheric. Cov hlau vuam tsis raug yuav tsum tau muab tshuaj ntxuav kom ntseeg tau tias tsis muaj oxidation hnyav, dej, roj av, xeb thiab lwm yam kab mob.
