Cov yam ntxwv uas cuam tshuam rau qhov ci ntsa iab ntawm stainless hlau pob tw-welded luj tshib thaum lub sij hawm annealing, qhov ci ntawm cov khoom tom qab annealing txiav txim siab qhov zoo ntawm cov khoom. Muaj ntau yam cuam tshuam rau nws qhov ci ci, thiab tsib yam tseem ceeb yog:
- Xyuas kom meej tias qhov kub ntawm annealing mus txog qib uas tau teev tseg. Kev kho cua sov ntawm stainless hlau pob tw-welded luj tshib feem ntau yog kev kho cua sov, feem ntau hu ua "annealing," nrog rau qhov kub ntawm 1040 ~ 1120 degree (raws li Japanese qauv). Qhov no tseem tuaj yeem pom los ntawm lub qhov cub tawg, qhov twg stainless hlau pob tw-welded luj tshib nyob rau hauv qhov chaw annealing yuav tsum tshwm incandescent tab sis tsis softened los yog sagging.
- Cov huab cua annealing feem ntau yog siv cov ntshiab hydrogen, nrog rau purity ntawm ntau tshaj 99.99%. Yog tias cov roj inert yog siv rau ib feem ntawm cov huab cua, qhov purity yuav tsum tau qis me ntsis, tab sis nws yuav tsum tsis txhob muaj cov pa ntau dhau los yog dej vapor.
- Kev sib khi ntawm lub qhov cub lub cev yog qhov tseem ceeb. Lub ci ci annealing rauv yuav tsum raug kaw thiab cais tawm ntawm huab cua sab nraud; Yog tias siv hydrogen los ua cov roj tiv thaiv, tsuas yog ib qho chaw nres nkoj yuav tsum qhib (kom ignite cov hydrogen tawm). Txhawm rau kuaj xyuas cov dej xau, so cov pob qij txha ntawm lub qhov cub annealing nrog xab npum dej kom pom tias muaj cov pa paug. Cov cheeb tsam uas cov yeeb nkab nkag mus thiab tawm ntawm lub qhov cub yog qhov tshwj xeeb tshaj yog muaj cov pa paug, vim tias cov nplhaib sib khi hauv cov cheeb tsam no hnav tau yooj yim thiab yuav tsum tau kuaj xyuas thiab hloov ntau zaus.
- Txhawm rau tiv thaiv micro-tawg, cov roj tiv thaiv hauv qhov cub yuav tsum tau khaws cia ntawm qee qhov zoo siab. Tsis tas li ntawd, cov roj tiv thaiv hydrogen feem ntau yuav tsum siab tshaj 20 kPa.
- Cov dej vapor hauv qhov cub yuav tsum tau ua tib zoo tswj. Ua ntej, xyuas seb cov khoom siv hauv lub tshuab hluav taws xob puas qhuav, tshwj xeeb tshaj yog thaum pib lub installation, thaum lub tshuab hluav taws xob lub cev yuav tsum tau qhuav kom huv si. Qhov thib ob, xyuas kom meej tias cov yeeb nkab steel hlau nkag mus rau hauv lub qhov cub tsis muaj dej ntau dhau, tshwj xeeb tshaj yog tias muaj cov qhov hauv cov yeeb nkab, vim tias cov dej nkag tuaj yeem ua rau lub qhov cub tawg tag.
Feem ntau, thaum lub cub tawg ua haujlwm ib txwm, cov yeeb nkab steel hlau yuav tsum pib ci li 20 meters tom qab nkag mus rau hauv lub qhov cub. Qhov no yuav tsum tau soj ntsuam thaum cov khoom tawm ntawm lub Hoobkas.
