1. Kub Rolling
Nruam casting slabs los yog pib dov slabs raws li raw cov ntaub ntawv, rhuab los ntawm ib kauj ruam cua sov rauv, high-pressure dej dephosphorization rau hauv lub roughing zeb, cov khoom roughing los ntawm txiav lub taub hau, tus Tsov tus tw, thiab ces mus rau hauv lub finishing mill, qhov kev siv ntawm lub computer-tswj dov, zaum kawg dov uas yog tom qab laminar txias npaum li cas (cooling tshuab) coiling, ua ncaj plaub hau yob. Lub taub hau thiab tus Tsov tus tw ntawm cov plaub hau ncaj yog feem ntau tus nplaig thiab fishtail zoo, tuab, dav qhov tseeb tsis zoo, feem ntau yoj-zoo li tus ntug, folded ntug, ntauwd thiab lwm yam tsis xws luag. Nws lub ntim hnyav hnyav, lub puab txoj kab uas hla ntawm steel kauj yog 760mm. (Cov yeeb nkab dav dav ua kev lag luam nyiam siv.) Cov plaub hau ncaj ncaj los ntawm kev txiav lub taub hau, tus Tsov tus tw, txiav ntug thiab ntau tshaj ib qho kev ncaj, theem thiab lwm yam kev ua tiav, thiab tom qab ntawd txiav phaj lossis rov yob, uas yog los ua: kub dov steel phaj, tiaj kub dov steel coils, longitudinal txiav sawb thiab lwm yam khoom. Kub dov xov coils yog lub pickling kom tshem tawm oxide daim tawv nqaij thiab oiled rau hauv kub dov pickled kauj. Daim duab hauv qab no qhia tau hais tiaskub dov coil.
2. Txias Rolled
Kub dov steel coils raws li raw cov ntaub ntawv, tom qab pickling kom tshem tawm cov oxide ntawm daim tawv nqaij rau txias dov, cov khoom tiav rau cov dov tawv ntim, vim tsis tu ncua txias deformation tshwm sim los ntawm txias hardening ntawm dov hardness ntawm lub zog, hardness, toughness thiab yas ntsuas poob, stamping kev ua tau zoo deterioration, tsuas yog siv tau yooj yim deformation ntawm qhov chaw. Rolled hard coil tuaj yeem siv los ua cov ntaub ntawv raw rau kub-dip galvanizing nroj tsuag, vim tias kub-dip galvanizing chav tsev yog teem nrog annealing kab. Rolled nyuaj coil hnyav yog feem ntau 6 ~ 13.5 tons, lub puab kab ntawm lub kauj yog 610mm. General txias dov phaj, coil yuav tsum tsis tu ncua annealing (CAPL unit) los yog hooded furnace de-annealing kev kho mob, tshem tawm txias hardening thiab dov kev nyuaj siab, kom ua tau raws li cov neeg kho tshuab zog teev nyob rau hauv cov qauv ntsuas. Txias dov steel phaj nto zoo, zoo li, qhov tseeb qhov tseeb yog zoo dua li kub dov phaj. Daim duab hauv qab no qhia tau hais tiastxias dov coil.
Qhov sib txawv tseem ceeb ntawmtxias dov vs kub dov steellies nyob rau hauv cov txheej txheem technology, Scope ntawm daim ntawv thov, mechanical zog thiab nto zoo, raws li zoo raws li tus nqi sib txawv. Hauv qab no yog cov lus qhia ntxaws:
Kev ua haujlwm. Kub dov yog ua tiav ntawm qhov kub thiab txias, thaum txias dov yog ua nyob rau hauv chav tsev kub. Kub dov yog dov saum lub crystallization kub, thaum txias dov yog dov hauv qab qhov kub ntawm crystallization.
Daim ntawv thov. Kub dov hlau yog tsuas yog siv nyob rau hauv steel lug lossis mechanical qhov chaw, nrog rau kev tsim kho choj, thaum txias dov hlau yog ntau siv nyob rau hauv kev lag luam tsheb los yog cov khoom siv me me, ntxhua khaub ncaws, tub yees, thiab lwm yam, nrog rau cov khoom siv.
Mechanical zog. Cov khoom siv txias txias yog feem ntau zoo dua li kub dov, vim tias cov txheej txheem txias dov ua rau cov nyhuv hardening lossis txias hardening, ua rau cov ntawv txias dov saum npoo hardness thiab lub zog siab dua, tab sis lub toughness qis dua, thaum lub zog ntawm cov ntawv kub dov yog tsawg dua cov ntawv txias dov, tab sis muaj qhov zoo dua toughness thiab ductility.
Nto zoo. Qhov zoo ntawm cov qauv saum npoo ntawm cov khoom siv txias txias yuav zoo dua li cov kub dov hlau, cov khoom siv txias txias yog qhov nyuaj dua thiab tsis tshua muaj ductile, thaum cov khoom kub dov muaj qhov rougher, textured nto.
Specification thickness. Cold rolled coils feem ntau yog nyias dua li cov kub dov, nrog rau cov tuab ntawm cov kab txias txias li ntawm 0.3 mus rau 3.5 millimeters, thaum kub dov coils muaj li ntawm 1.2 txog 25.4 millimeters.
Nqe: Feem ntau, txias dov yog me ntsis kim dua kub dov. Qhov no yog vim qhov txias dov yuav tsum tau siv cov cuab yeej ua haujlwm ntau dua thiab cov txheej txheem txheej txheem ntau dua, thiab kev kho mob khaub thuas dov tuaj yeem tau txais kev kho mob zoo dua, yog li qhov zoo ntawm cov khoom txias dov feem ntau yog siab dua, tus nqi sib raug siab dua. Tsis tas li ntawd, txias dov hlau nyob rau hauv cov txheej txheem ntau lawm yuav tsum tau nruj me ntsis ua technology thiab ntau dua ua nyuaj, cov khoom siv ntau lawm, yob thiab lwm yam khoom yuav tsum tau siab dua, uas yuav ua rau kom nce nyob rau hauv cov nqi ntau lawm.
