Txias Rolled Steel

Dab tsi yog Cold Rolled Steel

Cold rolled steel yog kub dov hlau uas tau dhau los ua cov txheej txheem ntxiv los txhim kho nws qhov loj me thiab cov khoom siv kho tshuab. Thaum lub sij hawm txias dov txheej txheem, txias kub dov steel dhau los ntawm lwm cov chais ntawm chav tsev kub. Txij li thaum cov khoom tsis kub thiab malleable, ib tug ntau dua npaum li cas ntawm lub siab yuav tsum tau compress nws mus rau hauv lub xav tau zoo. Thaum cov txheej txheem no tuaj yeem ua haujlwm hnyav dua thiab kim dua li cov txheej txheem kub dov, nws tuaj yeem ua tiav qhov kev tiv thaiv nruj dua thiab zoo dua qhov zoo.

Cov txiaj ntsig ntawm Cold Rolled Steel

Superior Durability
Cold dov steel los xij yuav ua tau ntev dua vim qhov ua haujlwm hardening. Cov txheej txheem no suav nrog kev nce ntawm cov hlau muaj zog nyob rau hauv kev siv tshuab siab. Hlau yuav nyuaj dua vim cov qauv hloov pauv raws li cov hlau muaju dislocate, flatten, plam rau ib leeg, thiab nruj thaum lub sij hawm txias dov. Raws li cov rollers siv siab, lawv ntim cov nplej hlau kom nruj li sai tau. Raws li qhov tshwm sim, hom hlau no zoo li 20% ntau ruaj dua li nws cov khoom kub-dov. Vim li no, nws tsis tas yuav siv nyiaj ntxiv-txhim kho cua sov. Yog vim li cas ntau lub lag luam nyiam txias-kuav los tiag steel.

Tight Dimensions
Txias dov steel sib txawv hauv cov tuab, tab sis lawv feem ntau nyias dua li cov ntawv kub dov. Steel mills tsim txias-dov coils nyob rau hauv lub 0 060 "- 0.105" thickness ntau yam. Vim ua hauj lwm hardening, ib tug muaj peev xwm tsim tau txias-dov coils ntawm tighter qhov ntev yam tsis muaj kev cuam tshuam lawv lub zog. Cov hlau zoo li no yog lub teeb yuag thiab ruaj khov. Yog li, ib daim ntawv txias-dov hlau nthuav tawm lub zog piv rau 50% thicker kub dov ib qho.Cold-dov hlau cov khoom tuaj yeem ua ke rau cov haujlwm hlau uas xav tau lub zog ntim hauv qhov me me, xws li cov rooj tog hlau, ru tsev, tsheb qhov chaw, hauv tsev. cov khoom siv, thiab lwm yam. Nyob rau sab saum toj ntawm qhov ntawd, qhov hnyav qis ua ke nrog kev ua haujlwm zoo dua ntawm cov hlau zoo li no tso cai rau koj kom txuag tau cov nqi tsheb thauj mus los.

Smooth kev ntxhib los mos
Thaum ib daim ntawv dov txias, nws tau txais ib qho kev ntxhib los mos vim yog hloov kho cov hlau muaju. Lawv rearrange thiab tsim coarse hlau nplej. Tsis tas li ntawd, hlau oxides thiab non-metallic inclusions tau nias rau hauv cov hlau nto thaum kub dov. Cov yam ntxwv no piav qhia tias yog vim li cas cov hlau kub dov yog qhov ntxhib heev, muaj qhov stained nto, thiab zoo li "dub" feem ntau.Tab sis qhov txias dov yog ib zaj dab neeg sib txawv. Raws li cov rollers compress thiab flatten hlau billets ntxiv, lawv cov nplej hlau tau elongated ntawm qib microscopic. Cov txheej txheem no cuam tshuam qhov kev ntxhib los mos ntawm cov hlau coils kawg, smoothing thiab nruj nreem ntim lawv cov hlau muaju. Nws txo qis qhov tsis zoo ntawm feem ntau, muab cov hlau ua polished, tsis muaj qhov projections lossis indentations.

Nce Dimensional raug
Raws li qhov ntim ntawm cov hlau nthuav dav ntawm qhov kub thiab txias, nws shrinks rov qab mus rau qhov qub hauv cov txheej txheem txias. Nws ua rau cov npoo ntawm cov coils kub dov mus rau me ntsis vim cov hlau txias tsis sib xws.Vim hlau tsis nthuav dav ntawm chav tsev kub, cov coils khaws lawv cov duab tom qab txias dov. Nws tso cai rau tsim cov ntawv hlau nrog cov npoo ncaj thiab tswj xyuas qhov tseeb ntawm qhov tseeb raws li qhov ua tau.

Yooj yim ntawm daim ntawv thov
Qhov xwm txheej ntawm cov hlau txias txias tso cai rau cov neeg siv khoom kom txuag tau kaum ob teev thiab ntau txhiab nyiaj rau kev ua hlau. Cov hlau los twb tawv thiab ci iab, thiab cov lag luam tuaj yeem txuag tau ntawm kev kho cua sov thiab polishing. Tsis tas li ntawd, koj tuaj yeem txuag tau ntawm kev ua haujlwm hlau vim tias cov coils txias dov muaj cov npoo ncaj thiab tsis tas yuav tsum tau ntau npaum li kev sib sau thiab sib tsoo li kub-dov hlau. Cov yam ntxwv no ua rau cov hlau npaj siv tau thiab, yog li ntawd, tus nqi qis.

Yuav ua li cas kom txias dov hlau

Kev tiv thaiv xeb

Siv cov kev tiv thaiv thaum koj qhov project tshiab kom tsis txhob muaj cov txheej txheem tshem tawm ntev tom qab. Rusting txias dov hlau yog qhov teeb meem loj; cia peb saib qee txoj hauv kev uas koj tuaj yeem tiv thaiv xeb ntawm steel nto.

Cia nws qhuav

Cov txheej txheem yooj yim tshaj plaws los tiv thaiv xeb yog ua kom cov hlau huv si thiab txwv tsis pub nws sib cuag nrog dej. Yog tias koj muaj ib qhov project, koj yuav tuav nws sab hauv tsev, kom ntseeg tau tias ib puag ncig tsis ntub dhau. Siv lub tshuab dehumidifier los khaws cov hlau hauv qhov chaw ntub dej, xws li hauv qab daus uas tsis tiav.Koj tsis tuaj yeem tiv thaiv los nag thiab daus yog tias koj muaj lub laj kab, lub tank, lossis lwm yam haujlwm uas yuav tsum tau zaum sab nraud, tab sis koj tuaj yeem tswj tau nws li. huv si li ua tau. Ntxuav cov khib nyiab, av nkos, lossis av tsis tu ncua.

Khaws khawb ntawm qhov chaw

Hlau khawb thiab pockmarks nthuav tawm ntau qhov chaw rau dej thiab ya raws. Qhov kev cuam tshuam no ua rau cov hlau khaws dej rau lub sijhawm ntev, ua rau muaj feem cuam tshuam ntawm xeb. Yog tias ua tau, khaws cov cuab yeej ntse thiab cov tshuab hnyav kom deb ntawm koj qhov project steel tiav. Xav txog cov hlau txias txias rau ib qhov project yuav raug tsim txom ntau. Cold-dov hlau muaj ib tug smoother nto thiab yog tsis tshua muaj yuav raug khawb li kub-dov hlau.

Siv cov txheej tiv thaiv

Hlau pobzeb rau ru tsev nyob rau hauv metallic forming tshuab ntau lawm kab nyob rau hauv lub Hoobkas. Txias dov steel coils ntawm cov nroj tsuag Nws raug nquahu kom siv cov khoom lag luam xeb tiv thaiv kom koj cov hlau tsis muaj dej noo ntau dua. Cov khoom no tuaj nyob rau hauv ntau hom, nrog rau cov ntaub so thiab aerosol sprays. Cov tshuaj siv los tiv thaiv xeb yog qhov zoo tagnrho rau cov haujlwm me me xws li cov khoom siv sab nraum zoov, cov cuab yeej, thiab cov rooj vag.Powder txheej ntau cov khoom siv hlau loj yog ib qho kev xaiv. Cov txheej txheem organic no tuaj hauv cov yas, urethane, epoxy, nylon, thiab acrylic ntau yam thiab ua haujlwm los ntawm kev tsim cov txheej tiv thaiv ib ncig ntawm cov hlau kom tsis txhob ya raws.
