1.What yog cov ntawv thov ntawm txias-}} rolled steel nyob hauv cov khoom siv hauv tsev thiab sab nrauv?
Tub yees: lub tub yees txee (sab thiab rov qab) thiab rooj cas (hlau chaw lwm yam dua li lub khob iav txias)} {rolled steel. Qhov no yog vim txias- rolled steel muaj ib tug du dig Nws cov tuab tuab yog uniform (feem ntau 0.3-0.8mm), tso cai rau nws tau ntim rau hauv cov nyom ntawm cov tub yees lub qhov rooj). Nws tseem muab ib co lej ntawm kev nruj me nyuam kom tiv thaiv deformation.
Ntxuav Machine: lub nruas nruas casing casing, tswj lub hauv paus, thiab txee casing ntawm pem hauv ntej {} {1} {rolled steel. Nyob rau hauv pem hauv ntej- phoo ntawv ntxhua khaub ncaws ntxhua khaub ncaws, tshwj xeeb, lub casing yuav tsum tau tiv thaiv lub ntsej muag me me ntawm lub nruas rotating. Cov txiaj ntsig lub zog ntawm txias- rolled steel (feem ntau 200 {{{}) muab cov qauv qauv txaus. Tsis tas li ntawd, tom qab phosphating thiab txau-txheej, cov nplaim dej tiv taus xeb xeb hauv qhov chaw noo noo.
Cov tshuab cua txias: lub tsev nyob sab hauv tsev ntawm sib faib - cov khoom siv sab hauv) thiab cov condenser) yog cov yas ua los ntawm txias- rolled steel. Chav tsev sab nraum zoov casing yuav tsum tau ua kom huab cua sab nraum zoov sab nraum zoov huab cua thiab cua. Txias - rolled steel yog powled, galvanized rau sab saum toj ntawm cov ntawv txias), thiab tom qab ntawd}}} kub} kew cov hlau tshwj xeeb kom txhim kho corrosion tsis kam. Rau chav tsev nyob sab hauv tsev, lub hom phiaj yog nyob rau saum npoo smoothness, kom tsis muaj pob los yog ua kom zoo nkauj ua yeeb yaj kiab, kom zoo nkauj rov qab ua yeeb yaj kiab.
Cov khoom siv me me, xws li microwave cub cov kab ke, qhov cub / saum, thiab cov khoom siv hlau hluav taws xob (thiab cov khoom siv dej sib dhos Cov cuab yeej siv me me no yog qhov tseem ceeb me me, thiab qhov sib txawv siab ntawm cov khaub thuas {2}, ua kom haum rau kev sib dhos ua ke ntawm lub teeb thiab sab hauv).
2.What yog cov kev siv ntawm txias- rolled steel nyob rau hauv cov txheej txheem sab hauv thiab cov haujlwm sib xyaw?
Cov qauv kev txhawb nqa cov Cheebtsam: Lub tub yees roj lim hiam (cov hlau hluav taws xob uas ruaj khov rau lub nruas rau lub nruas) Qhov rigidity ntawm txias- kov ntaub ntawv (muaj zog dua los ntawm cov khoom siv txias txias, ua kom muaj zog dua li kub ua ke tsis muaj kev ntxhov siab. Piv txwv li, lub nruas nkhaus ntawm lub tshuab ntxhua khaub ncaws yuav tsum dais qhov hnyav ntawm kev lwj khaub ncaws, thiab nws khoov kev tawm tsam tiv thaiv tawg.
Cov chaw ua haujlwm sib txuas: microwave cub qhov rooj pob khawm tshuab (txhawb nqa daim txiag ntoo (txhawb nqa daim tawv ncauj Cov feem no yuav tsum muaj ib theem ntawm kev hnav tsis kam thiab tawv. Stamping cov txiaj ntsig hauv cov npoo du rau txias- rolled daim ntawv (tsis muaj burrs feem ntau cuam tshuam nrog kub {}} rolled ntawv). Tom ntej kev kho cua sov (xws li ib feem ntawm kev quenching) tuaj yeem nce kev ua haujlwm saum npoo thiab txuas ntxiv lub neej. Thauj {{{{}} Cov kabmob} cov khoom siv hauv tub yees thiab cov txee cua txias) yuav tsum ris qhov hnyav ntawm tag nrho cov cuab yeej. Thicker txias - rolled daim hlau (1.0mm tuab) yog siv rau ib tug "} zoo li lub" lossis "l {14} zoo li tus qauv" zoo li tus qauv ". Lub zog compressive ntawm cov phiaj loj-rolled yog siv los faib qhov hnyav thiab tiv thaiv lub hauv paus los ntawm kev tsaus muag.
3.Qhov dab tsi yog qhov yuav tsum tau ua kom txias - rolled steel rau cov khoom siv hauv tsev?
Tsis muaj nplai los yog xeb: txias {{{k}}} rolled steel yog tsim los ntawm txias {1} {{2} {rolled steel. Ua ntej dov, nws undergoes pickling kom tshem cov nplai, uas ua rau muaj kev du, huv si dawb ntawm cov hlau oxide seem pom ntawm kub {}} rolled steel. Qhov no yog qhov yuav tsum tau ua ua ntej rau cov txheej txheej tom qab (hmoov txheej lossis pleev xim). Yog tias teev tau nthuav tawm nyob rau saum npoo, nws tuaj yeem yooj yim ua bubbling thiab tev tom qab pleev xim.
Tsawg tsawg roughning (RA tus nqi): Daj Rougness Ra tsawg dua los yog sib npaug ntawm 1.6μm feem ntau yuav tsum muaj cov khoom siv tsawg dua lossis sib npaug rau 0.8μm). Tsawg roughnness tshwm sim nyob rau hauv ib qho chaw ua si smoother, ua rau cov txheej txheem sib txawv ntawm cov hmoov av "(tsis sib xws} Tsis muaj qhov khawb lossis pitting: yog tias muaj qhov tsis xws luag nyob rau hauv cov txheej txheem txias, khawb thiab pitting yuav tshwm nyob saum npoo ntawm cov hlau phaj. Xws li tsis xws luag yuav ncaj qha rau cov tsos ntawm cov khoom siv hauv tsev (txawm tias cov xim pleev xim yuav pom cov cim). Yog li ntawd, feem ntau txias- rolled steel daim hlau muaj qhov chaw lag luam hauv tsev muaj qhov tsis zoo "thiab muaj qee qhov tsis xws luag).
4.Qhov cov khoom ntiag tug yog cov khoom ntiag tug rau cov khoom txias- rolled steel rau cov khoom siv hauv tsev?
Ductility (elongation): Ncab cov khoom siv ncab (xws li nkhaus ntawm lub tshuab nqus dej) -}} Tus qauv txias, kom tsis txhob ua tau zoo dua qub) kom tsis txhob tawg lossis wrinkling thaum ncab.
Tos lub zog: cov qauv txheej txheem (xws li nkhaus thiab cov hauv paus) yuav tsum muaj lub zog, feem ntau yog 200-300 mpa. Yog tias cov paib muaj zog yog tsawg dhau, deformation tom qab kev sib sau tuaj yeem tshwm sim (piv txwv li, tshuab ntxhua khaub ncaws bracket khoov hauv kev thauj khoom hauv qab). Yog tias nws tseem siab dhau, lub zog ntau dua thaum lub sij hawm stamping, uas tuaj yeem ua rau cov ris tsho pwm thiab tawg ntawm txoj kev khoov tau vim tias ntau dhau kev sib tw.
Cov ris tsho sib luag: cov khoom siv tshuab (xws li hardness thiab elongation) ntawm txias txias {{rolled steel ntawv tsis pub dhau ib pob yuav tsum tau hnav khaub ncaws. Txwv tsis pub, thaum lub sijhawm batch stamping, qee qhov feem yuav dhau cov txheej txheem tsim kev thaum lwm tus yuav tawg lossis deform, kev cuam tshuam ntau lawm.
5.Qhov twg yog qhov yuav tsum tau ua rau qhov raug txias ntawm txias - rolled steel rau cov khoom siv hauv tsev?
Thickness kam: qhov tuab ntawm sab nrauv ib txwm yog 0.3-0.8mm, nrog kev thev taus tsawg dua lossis sib npaug rau ± 0.02mm. Unrethen thickness tuaj yeem ua rau tsis ncaj ncees lub zog thaum lub sijhawm stamping, ua rau muaj kev cuam tshuam. Tsis tas li ntawd, cov tuab tuab tuaj yeem sib txawv thaum lub sijhawm pleev xim rau hauv cov phaj steel thiab thicker txheej ntawm thinner daim hlau, cuam tshuam rau lub tsos mob).
Phaj dav thiab kab ncaj qha: txias - bolled steel yuav tsum yog tus pas nrig tom qab) tom qab nrog ib phaj dav dav tsawg dua lossis sib npaug rau ± 0.5mm. Txwv tsis pub, tsis sib xws yuav tshwm sim thaum txiav, ua rau muaj kev tsis zoo nyob rau lub sijhawm tom ntej (piv txwv li, tsis sib xws nyob ntawm tub yees tsev nyob thiab qhov rooj).
