Isisombululo esikhanyayo se-annealing esibonelelwa yitekhnoloji ye H angao senza - eqaqambileyo ye-anneal ed egudileyo ityhubhu ngaphakathi nangaphandle komphezulu, ukuchaneka komgangatho wokunyamezelana, ukomelela okuphezulu, ukuxhathisa okuqinileyo komhlwa njalo njalo.Unokufumaneka njani umbhobho onjalo?
I-Austenitic steel stainless isetyenziswa ngokubanzi kwiintlobo ngeentlobo zezicelo zasekuhlaleni, zoshishino kunye nezomkhosi.Zifumaneka kwiintlobo ngeentlobo zeemveliso, ezifana nemivalo, iintonga, amaphepha, amaphepha, imichilo, i-foil, i-tubing, i-tubing, i-fittings, i-flanges kunye nezinye izinto zokubumba.
Ukuba insimbi engenasici iphathwa ubushushu kwisithando somlilo esiqhelekileyo, icandelo le-chromium kwintsimbi ye-austenitic stainless liya kusabela ngeoksijini emoyeni ukwenza i-gray oxide layer, ebizwa ngokuba yi-'scale', ekufuneka isuswe ngenkqubo yokukhetha.
Isisombululo esikhanyayo se-annealing sinokuyiphucula le nkqubo.Ukuze ugcine inkangeleko entle, gcina i-metallic luster yokuqala kwaye ugweme ukukha, i-austenitic stainless steel kufuneka ikhanyise i-annealed in annealed in protection okanye vacuum ukuthintela ukuguquka kombala.Onke amabakala e-austenitic steel stainless anokubanjwa.Umoya okhuselayo unokuba yi-hydrogen ecocekileyo, i-ammonia edibeneyo, okanye ngamanye amaxesha i-vacuum.Igesi ekhuselayo ikhusela i-oxidation yomhlaba yeemveliso ze-austenitic stainless steel ngexesha lokufakwa.
Ngoko ke, isisombululo esikhanyayo se-annealing sineenzuzo ezilandelayo:
I-1, i-annealing eqaqambileyo ayinciphisi nje ubunzima bombhobho wentsimbi, ukuphucula i-ductility, ukuphucula iplastiki, kodwa kulula ukusika kunye nokuguqulwa okubandayo.
2, phucula ukuxhathisa kwe-corrosion ngokususa imvula ye-intergranular carbide, ukuze inkangeleko yomphezulu ibe ntle.Ukucocwa okuziinkozo kunye nesakhiwo sensimbi efanayo kunye nokubunjwa, ukuphucula iimpawu zetsimbi, kodwa zilungiselele unyango olushushu.
I-3, ukuphelisa uxinzelelo lwangaphakathi olushiyekileyo kwintsimbi, ukuthintela ukuguqulwa kunye nokuqhekeka.
4. I-oxidation kunye ne-decarbonization yenzeke ngexesha lokufudumeza kunye nokupholisa kwi-annealing eqhelekileyo, ngoko ke intsimbi ephethwe ngubushushu iye yacutshungulwa eyongezelelweyo, eyandisa ilahleko kunye neendleko zetsimbi.
5. Ungafumani i-oxidation eqaqambileyo, indawo elungileyo yokumelana nomhlwa.Ngenxa yokuba i-annealing eqaqambileyo yonyango lobushushu lwentsimbi yentsimbi kwindawo ekhuselayo ye-hydrogen kunye negesi ye-nitrogen, umphezulu ngaphandle kwe-oxidation ifunyenwe ngokulawula ngokungqongqo igesi ekhuselayo eziko.Xa kuthelekiswa nomphezulu ofunyenwe ngokuxutywa okuqhelekileyo kunye nokucholwa, ngenxa yokuba akukho nkqubo ye-oxidation, isenzeko sokunqongophala kwe-chromium siyancitshiswa kumphezulu, kwaye ukuxhathisa kwayo kokubola kungcono emva kokupolisha.
6. unyango oluqaqambileyo ukugcina ukugqitywa kwendawo eqengqelekayo, ayinakuphinda iqhutywe kwaye ifumane indawo eqaqambileyo.Ngenxa ye-annealing eqaqambileyo, ubuso bombhobho bugcina i-luster yensimbi yasekuqaleni, ifunyenwe indawo eqaqambileyo, phantsi kweemfuno eziqhelekileyo, ingasetyenziswa ngokuthe ngqo ngaphandle kokucubungula ubuso bayo.
7.Akukho ngxaki yongcoliseko ebangelwa yindlela eqhelekileyo yokuchola.ene-anealed I-tube ayifuni ukuba i-pickling okanye unyango olufanayo, ungasebenzisi i-asidi, akukho zingxaki zokungcoliseka okubangelwa yi-pickling.
Ngoko sifike njani apho?
Izixhobo ze-On-line Fixing & Fusing (Anealing) zinokufudumeza insimbi engenasici edityaniswe ngombhobho we-1050 ° C emva koko uyipholise kubushushu obungaphantsi kwe-100 ° C phantsi kokhuseleko lwe-hydrogen. + Isakhiwo se-IGBT.Ngenkqubo yokulawula idijithali ye-DSP, kukho ukhuseleko lokuzimela kunye nokuzixilonga imisebenzi.Ngomthamo omncinci, ifudumeza imibhobho ngokukhawuleza kwaye ngokufanelekileyo kunye nezinto ezigcina amandla kunye nenkunkuma ephantsi. intsimbi inokonga i-15% -20% amandla ngokungafaniyo nezinye iimveliso zodidi olufanayo.Ukusebenzisa i-hydrongen njengegesi yonke ngomzuzu.
