Stainless hlau raj optical brightness tom qab annealing txiav txim siab zoo ntawm steel yeeb nkab. Muaj ntau yam cuam tshuam rau lub teeb, tab sis feem ntau ntawm tsib yam hauv qab no,

1. Seb qhov ncav cuag qhov xav tau kub, annealing kub. Stainless hlau cua sov kev kho mob feem ntau yog siv cov tshuaj kho cua sov, kuj yog cov neeg feem ntau hu ua "annealing", qhov kub ntawm 1050 ~ 1100 DEG C. Koj tuaj yeem soj ntsuam los ntawm kev soj ntsuam qhov ntawm qhov cub annealing, yuav tsum yog incandescent xeev annealing cheeb tsam ntawm stainless hlau raj, tab sis tsis muaj softening posies.

2. Cov cua sov ua kom sov. Feem ntau siv cov hydrogen ntshiab raws li qhov chaw annealing, huab cua ntawm qhov zoo tshaj plaws purity yog ntau tshaj 99.99%, yog tias huab cua yog lwm qhov ntawm cov roj inert, qhov purity kuj tuaj yeem qis me ntsis, tab sis tsis tuaj yeem muaj cov pa ntau dhau, dej vapor.

3. Rauv lub cev sealing. Ci ntsa iab annealing rauv yuav tsum raug kaw, cais tawm ntawm huab cua sab nraud; siv hydrogen raws li kev tiv thaiv roj, tsuas yog ib lub qhov hluav taws xob txuas nrog (siv rau ignite lub hydrogen paug). Txoj kev tshuaj xyuas tuaj yeem siv cov tshuaj soapy dej so hauv lub qhov cub annealing ntawm txhua qhov sib koom ua ke, saib seb puas muaj cov roj khiav; ib qho ntawm qhov yooj yim tshaj plaws los khiav cov pa roj yog qhov annealing furnace tube thiab tawm tube mus rau hauv lub zos qhov chaw, lub nplhaib sealing ntawm qhov chaw no yog tshwj xeeb tshaj yog yooj yim hnav, yuav tsum nco ntsoov xyuas qhov feem ntau hloov.

4. Kev tiv thaiv ntawm roj siab. Txhawm rau tiv thaiv qhov tshwm sim ntawm micro to, kev tiv thaiv ntawm lub cub tawg yuav tsum muaj lub siab zoo, yog tias tiv thaiv cov roj hydrogen, feem ntau xav tau ntau tshaj 20kBar.

5. Rauv dej vapor. Ntawm ib sab tes los xyuas seb cov khoom siv kom qhuav rauv lub cev, thawj lub tshuab ua kom sov, cov khoom siv hauv lub cev yuav tsum qhuav; Qhov ob yog seb cov dej seem ntau dhau mus rau hauv lub cub tawg ntawm stainless hlau raj, tshwj xeeb yeeb nkab saum toj no yog tias muaj qhov, tsis txhob xau rau hauv, lossis muab cov cua sov rau hauv qhov cub tawg tag.
