Stainless hlau seamless kav: Precision thiab muaj zog hauv txhua nti
1. Kev Npaj Billet: Cov txheej txheem pib nrog kev npaj ntawm cylindrical billets los yog cov khoom tuav ntawm stainless hlau. Cov ntaub ntawv nyoos no raug tshuaj xyuas kom zoo thiab sib xws ua ntej ua haujlwm ntxiv.
2. Cua sov thiab tho: Cov billets yog rhuab mus rau qhov kub thiab txias nyob rau hauv lub cub tawg kom lawv malleable. Thaum rhuab mus rau qhov zoo tshaj plaws kub, cov billets yog pierced los tsim hollow shells hu ua seamless hlab. Cov txheej txheem tho no ua kom muaj kev sib haum xeeb thiab qhov tseeb hauv txoj kab nruab nrab ntawm cov hlab.
3. Rolling thiab Sizing: Cov raj seamless yog tom qab ntawd dhau los ntawm cov txheej txheem ntawm cov chais kom ua tiav qhov xav tau sab nraud, phab ntsa tuab, thiab ntev. Cov txheej txheem dov no yuav koom nrog ntau qhov kev sib tw kom ua tiav qhov ntev thiab cov khoom siv kho tshuab.
4. Kev kho cua sov: Raws li cov kev cai tshwj xeeb ntawm daim ntawv thov, seamless stainless hlau kav yuav raug kho cov txheej txheem kub xws li annealing lossis quenching los txhim kho lawv cov khoom siv kho tshuab, tshem tawm cov kev ntxhov siab, lossis txhim kho corrosion.
5. Kev ua tiav: Tom qab kev tsim khoom, cov kav hlau tsis muaj seamless tuaj yeem ua tiav cov haujlwm tiav xws li pickling, passivation, lossis polishing kom ua tiav qhov kev xav tau ntawm qhov zoo nkauj, huv si, thiab zoo li.
Stainless hlau welded kav: Lub Zog Los Ntawm Fusion
1. Tube Tsim: Cov txheej txheem pib nrog kev tsim cov hlau stainless strips lossis coils, uas yog pub rau hauv lub raj zeb. Nyob rau hauv lub raj zeb, cov strips yog maj mam tsim rau hauv cylindrical duab siv ib tug series ntawm rollers thiab vuam electrodes.
2. Vuam: Ib zaug tsim, cov npoo ntawm stainless hlau strips yog welded ua ke siv high-frequency induction welding, TIG (Tungsten Inert Gas) vuam, los yog lwm cov txheej txheem vuam tsim. Cov txheej txheem vuam tsim kom muaj kev ruaj khov thiab ruaj khov ntawm cov npoo ntawm cov strips, tsim ib qho kev sib txuas txuas txuas ntxiv raws qhov ntev ntawm cov yeeb nkab.
3. Sizing thiab Shaping: Tom qab vuam, cov welded stainless hlau kav tau ua haujlwm sizing thiab shaping kom ua tau raws li qhov xav tau, nrog rau sab nraud, phab ntsa thickness, thiab ntev. Qhov no yuav koom nrog kev dov, qhov loj me, lossis cov txheej txheem trimming kom ua tau raws li cov lus qhia meej.
4. Kev kho cua sov thiab ua tiav: Zoo ib yam li cov kav dej seamless, welded stainless hlau kav tej zaum yuav raug kev kho cua sov thiab kev ua tiav saum npoo los txhim kho lawv cov khoom siv kho tshuab, tiv thaiv corrosion, thiab zoo li.
Kub Rolling vs. Txias Rolling: Shaping Stainless Steel Pipes
Ntxiv nrog rau txoj kev tsim khoom seamless thiab welded, cov kav hlau tsis muaj steel tuaj yeem tsim tau siv cov txheej txheem kub dov lossis txias dov, txhua qhov muab cov txiaj ntsig tshwj xeeb:
1. Kub Rolling: Kub dov yuav dhau los ntawm stainless hlau billets los yog ingots los ntawm ib tug series ntawm dov mills ntawm kub kub. Cov txheej txheem no ua rau cov kav dej tsis muaj steel hlau nrog cov nplais nto thiab cov ntxhib ntxhib ntxhib ntxhib ntxhib los mos. Kub-dov stainless hlau kav yog paub rau lawv zoo heev mechanical zog thiab formability, ua rau lawv haum rau daim ntaub ntawv uas yuav tsum tau muaj zog thiab ductility.
2. Txias Rolling: Txias dov yuav dhau los ntawm cov ntawv hlau stainless lossis cov coils los ntawm cov dov mills ntawm chav tsev kub lossis hauv qab me ntsis. Cov txheej txheem no ua rau cov kav hlau tsis muaj steel nrog lub ntsej muag du thiab meej qhov ntev. Cov kav dej txias-dov stainless hlau muaj qhov zoo tshaj plaws ntawm qhov chaw, qhov tseeb qhov tseeb, thiab nruj dua rau cov kav dej kub dov. Lawv feem ntau siv rau hauv cov ntawv thov uas qhov kev zoo nkauj thiab kev tswj qhov loj me yog qhov tseem ceeb, xws li kev tsim vaj tsev, tsheb, thiab kev siv kho kom zoo nkauj.
