Txias Rolled Steel Sheet

Cov ntawv hloov tau txias yog tsim los ntawm cov kav ntev ua cov ntaub ntawv raw thiab muab dov rau ntawm chav tsev kub.Cov cuab yeej siv sib tsoo txias hlauyog cov ntawv hlau ua los ntawm cov txheej txheem dov txias, xa mus ua cov ntawv txias. Lub tuab ntawm cov ntawv txias yog feem ntau ntawm 0.1 txog 8.0mm. Lub thickness ntawm txias-dov daim ntawv tsim los ntawm feem ntau cov Hoobkas yog tsawg dua 4.5mm. Cov tuab thiab dav ntawm cov ntawv txias yog txiav txim siab raws li cov cuab yeej siv muaj peev xwm thiab kev xav tau ntawm kev ua lag luam ntawm txhua tsob nroj. Piv nrog hotrolled steel ntawv, lub thickness ntawm coldrolled steel ntawv yog ntau muaj tseeb, thiab saum npoo yog ntau du thiab zoo nkauj.

Kub dov: Lub pob zeb sib tsoo (feem ntau nruam casting slab) yog siv los ua cov khoom siv raw, thiab tom qab cua sov, nws tau ua rau cov nplawm steel los ntawm ntxhib dov zeb thiab lub zeb kawg. Qhov kub steel sawb los ntawm lub xeem dov zeb ntawm lub xov zeb kawg yog txias rau lub teeb kub los ntawm laminar txaus, thiab tom qab ntawd dov mus rau hauv txoj hlua steel npuag los ntawm coiler. Cov laj kab txias steel sawb yob ua haujlwm txawv cov haujlwm ua haujlwm raws li qhov sib txawv ntawm cov neeg siv. Cov kab (du, ncaj, hla-txiav los yog pob, kev soj ntsuam, hnyav, ntim thiab kos cim, thiab lwm yam) yog ua tiav rau hauv cov hlau phaj, tiaj tiaj thiab pob hlau loj cov khoom lag luam. Txhawm rau muab nws yooj yim, tom qab ua kom sov daim hlau steel billet (ntawd yog qhov kub liab lub npov hlau thaiv hauv TV), nws tau dov ntau zaus, tom qab ntawd txiav, thiab kho kom dhau los ua cov hlau phaj. Qhov no yog hu ua kub dov.

Cov dov txias: Kub dov npuag ntsia hlau yog siv los ua khoom siv, thiab cov nplai yog tshem tawm los ntawm pickling thiab tom qab ntawd txias nruam dov. Cov khoom tiav yog ib pob hlau sib tsoo. Kev ua haujlwm txias khov kho los ntawm kev hloov pauv tsis tu ncua ua rau lub zog, ua kom tawv thiab cov tawv ntawm cov tawv tawv kom khov. Lub plhaw yas poob qis, yog li ntawd cov ntawv ntaus cim yuav ua kom tsis zoo thiab tsuas yog siv rau qhov chaw ua kom yooj yim. Cov ntawv sib sau tau yooj yim tuaj yeem siv los ua raw cov ntaub ntawv rau kub-dip galvanizing nroj tsuag vim tias kub-dip galvanizing units tau nruab nrog cov kab ua kom npau taws. Qhov hnyav ntawm cov tawv kuav los tiag yog feem ntau 6 ~ 13,5 tons, thiab cov kauj hlau txuas ntxiv tsis tu thaum muaj qhov kub ntawm qhov ceev ntawm qhov kub-kuav los tiag pickled kauj. Lub taub puab yog 610 hli.

Cov yam ntxwv khoom: Vim tias nws tsis tau annealed, nws qhov nyuaj yog siab heev (HRB ntau dua 90), thiab nws cov khoom siv ua haujlwm yog qhov tsis zoo. Nws tsuas tuaj yeem ua tau yooj yim thiab cov kev taw qhia khoov ua kom tsawg dua 90 degrees (txiav ua ke rau qhov ntsuas winding).

Txhawm rau muab nws yooj yim, dov txias yog txheej txheem thiab dov ntawm lub hauv paus ntawm kub-dov lub kauj. Feem ntau hais lus, nws yog txheej txheem ntawm cov kub dov --- pickling --- txias dov.

Cov ntawv txias txias yog tsim los ntawm daim ntawv kub-dov nyob ntawm chav sov. Txawm hais tias daim ntawv hlau yuav raug rhaub thaum dov vim tias yob, nws tseem hu ua dov dua. Vim hais tias cov dov kub yauv ua tas mus li txias deformation thiab txias dov, cov khoom kho tshuab tsis zoo, thiab lub hardness yog siab dhau. Nws yuav tsum tau annealed los kho nws cov yam ntxwv kho tshuab, thiab cov uas tsis muaj annealing hu ua dov nyuaj coils. Rolled hard coil feem ntau yog siv los ua cov khoom yam tsis muaj khoov thiab ncab.

Daim ntawv thov: Cov khaub thuas kuav los tiag cov khaub thuas sib xyaw tau siv dav, xws li kev tsim tsheb, cov khoom siv hluav taws xob, dov Tshuag, kev tsav dav hlau, ntsuas cov khoom siv, cov kaus poom zaub mov, thiab lwm yam. hu ua cov ntawv ua npuag txias, feem ntau hu ua cov ntawv txias, thiab qee zaum sau tsis raug raws li daim ntawv txias npuag. Cov phaj txias yog tsim los ntawm cov pa roj carbon zoo tib yam txheej txheem steel kub-kuav los tiag cov hlua khov, uas yog txuas ntxiv txias dua los ua cov phaj steel nrog cov tuab tsawg dua 4 hli. Vim hais tias dov nyob rau hauv chav tsev kub tsis tsim nplai, yog li ntawd, qhov chaw zoo ntawm lub phaj txias yog qhov zoo, qhov ntsuas qhov tseeb yog qhov siab, thiab cov tshuaj kho tsis haum, nws cov cuab yeej muaj zog thiab cov txheej txheem ua tau zoo dua li kub-kuav los tiag nyias steel phaj, hauv ntau lub teb, tshwj xeeb tshaj yog kev tsim cov khoom siv hauv tsev, nws tau maj maj hloov cov thawv kub hnyav nyias nyias cov phiaj hlau.
