S235JR S275JR S355JR Carbon Steel Phaj
1. Thermal calendering processing method muaj xws li kub dov, forging, extrusion thiab lwm txoj kev.
(1) Kub dov txoj kev Kub dov txoj kev yog ib txoj kev ntawm cov cua kub hlau mus txog 1000 ℃ ~ 1250 ℃ thiab ua cov ntaub ntawv los ntawm dov tshuab.Cov txheej txheem kub dov cov txheej txheem feem ntau muab faib ua ob kauj ruam hauv qab no: thawj kauj ruam yog siv lub pob zeb thawj zaug los yog pob zeb rau dov lub ingot, billet los yog nruam casting billet rau hauv ib qho duab thiab qhov loj ntawm cov pob zeb.Cov txheej txheem dov no feem ntau hu ua semi-tiav lawm, tseem hu ua billet ntau lawm.Qhov thib ob kauj ruam yog siv cov sib txawv tiav dov mills los yob lub billet los yog nruam casting billet rau hauv cov hlau tiav ntawm cov duab tsim nyog thiab loj.Cov txheej txheem no yog hu ua tiav lawm, uas feem ntau muab faib ua ob theem: ntxhib dov thiab ua tiav dov.Nyob rau hauv qhov ntxhib dov theem, txais yuav cov ntim loj (txhua dov) thiab tom qab ntawd nkag mus rau qhov kawg dov theem nrog me me kom ua tiav qhov zoo thiab qhov loj me.Nrog rau txoj kev loj hlob ntawm kev nruam casting ntau lawm, ntau lub lag luam siv nruam casting billet li raw khoom, tsuas yog siv cov kauj ruam thib ob saum toj no los tsim steel, thiab mus rau cov kev taw qhia ntawm nruam casting thiab dov.(2) forging thiab nias txoj kev forging yog siv. ntawm forging rauj, precision forging tshuab, ceev forging tshuab los yog hydraulic xovxwm ntawm steel ingot forging rau hauv steel, billet los yog forging dawb paug.Forging yog ib txoj kev ua thaum ntxov, thiab forging muab faib ua ob hom, dawb forging thiab qauv forging.Forging txoj kev tuaj yeem tau txais kev ua haujlwm zoo dua qub thiab dov txoj kev tsis yooj yim lossis tsis tuaj yeem tau txais cov duab ntawm cov hlau tiav. los ntawm lub qhov ntawm lub tog raj kheej extrusion, tsim ib ntu me dua qhov khoob, thiab muaj qee qhov seem ntawm cov profile, cov yeeb nkab lossis cov khoom siv hollow.Cov txheej txheem extrusion yog siv los tsim cov khoom uas nyuaj los ntawm kev kub dov (xws li cov seem steel, stainless hlau yeeb nkab, thiab lwm yam).
2. Cov txheej txheem txias dov muaj xws li txias dov, kos duab txias, kos duab txias, txias khoov, txias extrusion thiab lwm txoj kev.Txias calendering txheej txheem yog mus txuas ntxiv ua cov hlau tom qab kub dov hauv qab qhov kub ntawm recrystallization, thiab ua rau nws mus rau hauv txias calendering ua hlau.Cov txheej txheem txias dov tuaj yeem txhim kho cov khoom siv ntawm cov hlau, thiab tau txais cov khoom lag luam nrog qhov tseeb qhov tseeb thiab qee qhov tiav. dov steel bar.Cold-rolled steel phaj tuaj yeem tsim los ntawm ob-yob dov zeb, plaub-yob rov qab dov zeb, ntau yob rov qab dov zeb thiab txias nruam dov zeb.
