Kev tsim cov txheej txheem ntawm stainless hlau xaim: los ntawm raw khoom mus rau cov khoom tiav

Stainless hlau hlau yog ntau yam khoom siv dav siv hauv ntau qhov kev lag luam vim nws cov kav ntev, corrosion tsis kam thiab siab tensile zog.Nkag siab txog cov txheej txheem tsim khoom ntawm stainless hlau xaim los ntawm cov khoom siv raw mus rau cov khoom tiav yog qhov tseem ceeb.Kab lus no yuav muab cov lus qhia tob rau kev tsim cov qauv ntawm cov hlau tsis muaj steel hlau thiab cov txheej txheem kev koom tes hauv cov txheej txheem ntau lawm.

Kev tsim kev taug kev ntawm stainless hlau xaim pib nrog kev xaiv cov khoom siv raw.Lub ntsiab tivthaiv ntawm stainless hlau hlau yog chromium, uas ua rau kom cov corrosion kuj ntawm cov khoom kawg.Tsis tas li ntawd, lwm cov ntsiab lus xws li npib tsib xee, carbon thiab manganese tau ntxiv los txhim kho cov yam ntxwv tshwj xeeb ntawm cov hlau, xws li lub zog thiab kev tsim.Cov ntaub ntawv nyoos no tau ua tib zoo ntsuas thiab sib xyaw ua ke hauv qhov sib luag kom ua tiav cov khoom xav tau.

Thaum cov khoom siv sib xyaw ua ke, lawv tau dhau los ua txheej txheem melting.Cov sib tov yog rhuab nyob rau hauv ib tug heev tswj ib puag ncig, feem ntau nyob rau hauv ib tug hluav taws xob rauv.Raws li qhov kub nce siab, cov khoom siv raw melts thiab tsim cov kua stainless hlau alloy.Lub molten stainless hlau yog ces poured rau hauv pwm los tsim ib tug semi-tiav khoom xws li billets los yog ingots.

Cov kauj ruam tom ntej hauv kev tsim khoom yog kub dov ntawm cov khoom semi-tiav.Ib tug billet los yog ingot yog rhuab thiab dhau los ntawm ib tug series ntawm rollers, maj mam txo nws thickness.Cov txheej txheem kub dov pab ua kom zoo dua cov qauv ntawm cov hlau tsis huv thiab txhim kho nws cov khoom siv kho tshuab.Lub thickness txo qhov ua tiav thaum lub sij hawm kub dov yog qhov tseem ceeb kom tau txais qhov xav tau stainless hlau hlau txoj kab uas hla.

Tom qab kub dov, stainless hlau mus los ntawm tus txheej txheem hu ua annealing.Annealing yog kom sov stainless hlau xaim mus rau qhov kub thiab txias thiab khaws cia rau lub sijhawm teem tseg.Cov txheej txheem no txo ​​cov kev ntxhov siab sab hauv, softening cov khoom thiab ua rau nws ntau malleable.Annealing kuj refines cov qauv siv lead ua thiab txhim kho lub machinability thiab formability ntawm hlau.

Tom qab annealing, stainless hlau xaim yog npaj rau kev kos duab txias.Kev kos duab txias suav nrog kev kos cov hlau los ntawm kev tuag kom maj mam txo nws txoj kab thiab ua kom nws ntev.Cov txheej txheem kuj txhim kho qhov chaw tiav ntawm cov hlau, tshem tawm cov kev ntxhov siab sab hauv thiab txhim kho nws cov khoom siv kho tshuab.Stainless hlau xaim tuaj yeem kos tau ntau zaus kom ua tiav txoj kab uas xav tau, kom ntseeg tau qhov sib xws thiab zoo.

Cov kauj ruam kawg hauv kev tsim khoom yog kev kho saum npoo.Stainless hlau hlau feem ntau yuav tsum tau kho deg xws li pickling, passivation los yog txheej txheej txheem, nyob ntawm seb nws xav tau daim ntawv thov.Pickling suav nrog tshem tawm nplai lossis impurities los ntawm qhov chaw ntawm cov hlau, thaum passivation tsim ib txheej nyias oxide uas txhim kho corrosion kuj.Txheej txheej txheem xws li electroplating lossis galvanizing kuj tuaj yeem siv los muab kev tiv thaiv ntxiv lossis txhim kho cov tsos ntawm cov hlau.
