I. Cov txheej txheem ntau lawm ntawm kub -} rolled seamless yeeb nkab
- Cov Khoom Siv Khoom Raw:Xaiv cylindrical, siab - Cov hlau ua tau zoo los yog cam kas nrib rov qab cov nqi.
- Cua Sov:Lub billet yog rhuab nyob rau hauv ib tug cua sov rau nws cov yas deformation kub (feem ntau nyob ib ncig ntawm 1200 degree, muag muag nws thiab ua rau nws yooj yim dua ua haujlwm.
- Tho:Qhov no yog ib kauj ruam tseem ceeb hauv seamless yeeb kev tsim khoom. Lub based raits yog pub rau hauv ib lub zeb khi (feem ntau tus ntoo khaub lig- rolling Piercer lossis ib siab ntsws).
- Dov:Hollow Billet (hu ua lub raj ntxhib) Tom qab tho tau tsis sib xws phab ntsa thickness thiab ntxhib sab hauv cov phab ntsa tuab, ncab nws, thiab du nws roundness. Cov cuab yeej siv ntau zaus suav nrog cov yeeb nkab siv hluav taws xob tsis siv neeg, peb {1} mills, yeeb nkab mills, thiab extruders.
- Sizing:Cov siv cov hlau siv (hu ua cov raj ntxhib) yuav tsum ua kom tiav qhov txheej txheem txheej txheem ntawm lub taub thiab kev ncig zoo. Cov txheej txheem no feem ntau ua tiav siv sizing zeb (ob peb ob {1} {{{{{{{{{{{2} Txo cov kab mob hla thiab phab ntsa tuab). Tus txheej txheem no feem ntau tshwm sim ntawm dov qhov kub.
- Cua txias:Cov yeeb nkab yob tau txias rau chav sov rau ntawm lub txaj txias lossis taug kev nqaj.
- Ncaj:Lub txias txias steel yeeb yuav khoov thiab xav tau kom ncaj rau hauv ib qho ncaj.
- Trimming, kev sib piv, thiab tshuaj xyuas:Tsis xwm txheej ntawm cov yeeb nkab xaus yog txiav txiav, thiab cov qauv kuaj tau coj los ntsuas cov khoom siv cov khoom siv tshuaj kho thiab tshuaj lom neeg. Nondestructive xeem (xws li kev sim ultrasonic thiab eddy tam sim no) kuj tau ua, nrog rau kev kuaj hydrostatic, thiab kuaj pom.
- Ntim thiab Warehousing:Cov khoom tsim nyog yog tshuaj tsuag -}}}}}}} eced (rau xeb kev tiv thaiv), thiab bundled rau cia.
Ii. Cov txheej txheem ntau lawm ntawm khaub thuas kos / txias dov seamless yeeb nkab
- Cov Khoom Siv Khoom Raw:Barrel lossis semi -} ua tiav txoj hlab, feem ntau ua los ntawm kub dov, yog siv los ua cov khoom siv raw (hu ua cov raj xwb).
- Pickling:Nplai nplaim tshem tawm.
- Lubrication:Phosphaating thiab saponification tau ua rau ntawm lub raj pam vov los txo kev sib txhuam thaum kos duab tom ntej.
- Ciav Txias:Ib kawg ntawm lubricated raj dawb yog clamped thiab rub los ntawm ib lossis ntau tus tuag qhov (tuag) siv lub zog sab nraud (saw hlau lossis cov raj hydraulic raj drawb). Cov taub uas hla sab nraud yog txo qis, thiab cov phab ntsa tuab yuav sib txawv (tswj tau nrog lossis tsis muaj ib qho mandrel). Nruab nrab annealing yog yuav tsum tau tshem tawm ua haujlwm tawv. Tsis tshua muaj neeg ntev ntev yuav ua tau.
- Cuav Dov:A multi-roll cold rolling mill (such as a two-roll cyclic cold rolling mill or a multi-roll cold rolling mill) is used. Lub raj xa tawm tau muab tso rau ntawm daim tawv nrig thiab tawm ntawm cov khaub lig sib txawv, ua tiav qhov chaw loj, thiab phab ntsa tuab zoo nkauj. Nruab nrab annealing kuj yuav tsum tau.
- Kev Kho Cua Sov:Tom qab ua haujlwm txias, annealing, li qub, quenching, Temiling, thiab lwm yam kev yuav tsum tau muaj microstre thiab cov khoom siv.
- Xov:Ncaj, txiav, tshuaj ntsuam (sab, sab, tsis- Kev sim ua dej num, thiab lwm yam), thiab ntim.
