Raws li txoj kev molding: cam khwb cia yob thiab forged yob.
Castingyobxa mus rau cov hom yob tsim los ntawm ncaj qha casting ntawm smelted molten steel los yog smelted molten hlau.
Casting yob tuaj yeem muab faib ua ob pawg: cam khwb cia hlau yob thiab cam khwb cia hlau yob raws li cov khoom siv;Raws li kev tsim khoom, lawv tuaj yeem muab faib ua ob pawg: cov khoom sib xyaw ua ke thiab cov khoom sib xyaw ua ke.
Forging rolls yog cais los ntawm cov khoom raws li hauv qab no:
(1) Forging alloy steel yob;
(2) Forging semi-steel yob;
(3) Forging semi-high-speed steel yob;
(4) Forged dawb cam khwb cia hlau yob.
Raws li tus txheej txheem txheej txheem:Integral rolls, metallurgical composite rolls thiab ua keyob.
1. Muab piv nrog cov yob sib xyaw, tag nrho cov yob yog cam khwb cia lossis forged nrog ib qho khoom siv rau txheej txheej, cov tub ntxhais thiab lub caj dab ntawm tag nrho cov yob.Cov txheej txheem txheej txheej ntawm lub cev yob thiab lub caj dab muaj cov qauv sib txawv thiab cov khoom siv los ntawm cov txheej txheem casting lossis Forging thiab cov txheej txheem kho cua sov los tswj thiab kho.Ob qho tib si forged rolls thiab static cam khwb cia yob yog ib qho rolls.Integral rolls tau muab faib ua ib qho casting thiab ib qho forging yob.
2. Metallurgical composite casting yob feem ntau suav nrog semi-flushing composite casting, overflow (full flushing) composite casting, thiab centrifugal composite casting.Hom sib xyaw yob tsim los ntawm cov txheej txheem tshwj xeeb xws li isostatic nias (HIP-Kub Isostatically Pressed) thiab electroslag vuam.Cov yob sib xyaw ua ke feem ntau yog cov txheej txheem sib xyaw ua ke.
Los ntawm kev tsim khoom:
Cam khwb cia steel series yob, cam khwb cia hlau series yob thiab forged series yob
Feem ntau siv hom kev kho cua sov rau yob: kev ntxhov siab nyem annealing, isothermal spheroidizing annealing, diffusion annealing, normalizing, tempering, quenching, cryogenic kho.
Raws li cov duab ntawm lub cev yob:
Muaj ntau txoj kev faib tawm rau yob.Raws li cov duab ntawm lub cev yob, nws tau muab faib ua cylindrical thiab non-cylindrical, lub qub yog tsuas yog siv rau kev tsim cov phaj, strips, profiles thiab xov hlau, thiab tom kawg yog siv los tsim cov kav dej.
Raws li seb nws yog nyob rau hauv kev sib cuag nrog lub dov daim:
Muab faib ua haujlwm yob thiab thaub qab yob.Cov rolls uas ncaj qha mus rau lub dov Tshuag yog hu ua ua hauj lwm rolls;cov yob uas tau muab tso rau sab nraub qaum lossis sab ntawm cov yob ua haujlwm yam tsis muaj kev sib cuag ncaj qha rau cov yob cov khoom kom nce qhov tawv thiab lub zog ntawm cov yob ua haujlwm yog hu ua thaub qab yob.
Raws li kev siv lub khib nyiab:
Raws li kev siv cov khoom muag, nws tau muab faib ua cov yob yob, roughing yob, nruab nrab yob thiab tiav yob.Raws li ntau yam ntawm cov ntaub ntawv dov, nws tau muab faib ua strip rolls, rail beam rolls, wire rod rolls thiab pipe rolls.Nws kuj tseem tuaj yeem muab faib ua cov yob kub thiab txias yob raws li lub xeev ntawm dov Tshuag thaum dov.
Raws li tus nqi hardness:
(1) Mos rolls Shore hardness yog hais txog 30 ~ 40, siv rau deburring tshuab, ntxhib dov mills ntawm loj seem steel mills, thiab lwm yam.
(2) Semi-hard rolls Shore hardness yog hais txog 40 ~ 60, siv rau ntxhib dov mills ntawm loj, nruab nrab thiab me seem steel mills thiab steel phaj mills.
(3) Hard-faced rolls Shore hardness yog hais txog 60 ~ 85, siv rau ntxhib dov mills ntawm nyias phaj, nruab nrab phaj, nruab nrab seem steel thiab me me seem steel mills thiab thaub qab yob ntawm plaub-siab dov mills.
(4) Cov khoom siv tawv tawv tawv tawv tawv yog li 85 ~ 100, siv rau hauv cov tshuab txias dov.
Raws li hom ntawmdov zeb:
(1) Flat yob.Qhov ntawd yogRolling Mill Rolls, lub cev yob yog cylindrical.Feem ntau, cov rolls ntawm cov kub dov steel zeb yog ua rau ib tug me ntsis concave zoo, thiab thaum rhuab thiab nthuav, ib tug zoo zoo yuav tau txais;cov rolls ntawm lub txias-dov steel zeb yog ua rau ib tug me ntsis convex duab, thiab cov yob yog khoov thaum dov kom tau ib tug zoo zoo.
(2) Grooved yob.Nws yog siv rau dov loj, nruab nrab thiab me me, hlau rods thiab tawg paj.Grooves yog engraved rau ntawm qhov chaw yob kom zoo li cov khoom dov.
(3) Cov yob tshwj xeeb.Nws yog siv nyob rau hauv tshwj xeeb rolling mills xws li steel yeeb nkabdov mills, log dov mills, steel pob dov mills thiab tho mills.Cov yob ntawm lub tshuab yob no muaj ntau yam duab, xws li cov yob yob los ntawm lub hauv paus ntsiab lus ntawm skew dov hauv cov yeeb nkab steel dov, uas yog conical, duav nruas lossis disc.
