Rolled rings (tseem hu ua seamless forged rings) muaj toroidal lossis donut zoo li. Rolled nplhaib cov khoom lag luam tuaj yeem muaj qhov loj me los ntawm me me, lub nplhaib zoo li lub tshuab ntxhua khaub ncaws mus rau qhov loj tshaj 9 feet ntawm txoj kab uas hla. Rolled rings feem ntau nyob ze ntawm cov duab los yog pib cov khoom tsis muaj, uas tau dhau los ua ntxiv, machining, thiab sib tsoo los tsim cov khoom tiav.
Rings machined los ntawm cov khoom forged los yog wrought dawb paug tej zaum yuav muaj cov khoom zoo sib xws (sans circumferential grain flow). Txawm li cas los xij, cov txheej txheem ze ze ntawm lub nplhaib forging txo cov khoom seem piv rau kev txiav thiab machining rings los ntawm cov khoom wrought block los yog dawb paug, uas ua rau machining thiab cov khoom txuag nqi rau cov neeg siv khoom. Lub nplhaib dov txheej txheem tuaj yeem tsim qhov chaw rau cov geometries tshwj xeeb thiab nruj tolerances nrog zoo heev concentricity thiab nto smoothness. Cov cwj pwm no tuaj yeem ua rau muaj kev txuag nyiaj ntxiv yog tias lub forged nto thiab kam rau ua tau raws li qhov xav tau ntawm tus engineer.
Rau ntau cov khoom siv uas xav tau lub nplhaib puab, ib qho casting lossis hmoov hlau tuaj yeem muaj cov khoom txaus. Txawm li cas los xij, cov khoom siv hlau thiab cov hmoov hlau feem ntau muaj cov porosity sab hauv, ua rau txo qis qaug zog, creep, thiab toughness teeb meem piv rau 100% ntom wrought daim ntawv. Cov txheej txheem solidification thaum lub sij hawm casting tshwm sim nyob rau hauv muaj pes tsawg leeg nyob rau hauv-homogeneities, uas yuav cuam tshuam rau txhua yam khoom thiab corrosion kuj. Hauv qee qhov kev xav tau nrog kev ntxhov siab, qhov kub thiab txias, thiab kev thauj khoom cyclic, cov khoom siv siab ncaj ncees nrog cov qauv ntom ntom, homogeneous yog qhov tsim nyog yuav tsum tau ua.
Rolled nplhaib manufacturers siv ib tug tshwj xeeb qhib tuag forging txheej txheem uas aligns cov nplej ndlwg ntawm cov hlau nrog cov tuag thiab kaw tej porosity nyob rau hauv, ua qhov chaw nrog kev kwv yees grain qauv thiab cov khoom zoo ib yam. Cov txheej txheem no ua kom lub nplhaib tiav uas yog homogeneous, muaj zog, thiab muaj kev qaug zog zoo heev, nkag mus, thiab cuam tshuam cov yam ntxwv. Mandrel nplhaib forging yog lwm cov txheej txheem rau kev tsim cov khoom siab ncaj ncees rau kev txiav txim me me lossis cov nplhaib hnyav heev. Cov txheej txheem dov lub nplhaib forging muaj kev ntxhov siab los tsim qhov pib disc zoo, tho thiab shearing lub disc duab los ua ib tug donut preform, ces ua lub preform rau hauv dov nplhaib puab nrog ib tug mandrel thiab cones nyob rau hauv zeb.
Rolled rings tej zaum yuav yog cov duab plaub, nyob rau hauv qhov chaw hla ntawm lub nplhaib dov muaj lub tiaj, duab plaub; los yog profiled, nyob rau hauv uas tus ntoo khaub lig seem muaj tej contours los yog profiles ib tug kos duab los yog tsim yuav tsum tau.
Khoom siv
Cov neeg tsim khoom feem ntau muab cov nplhaib dov rau hauv ib lossis ntau dua ntawm cov hlau hauv qab no lossis cov alloys:
Hlau alloy
Aluminium los yog aluminium alloys
Cov pa roj carbon steel
Cobalt hlau
Tooj liab los yog tooj liab alloys
Nickel alloys
Stainless hlau
Titanium los yog titanium alloys
Cov cuab yeej steel
Nta
Raws li-dov: Lub nplhaib dov yog muab rau hauv qhov zoo li-dov uas tus neeg yuav khoom yuav muab kev kho cua sov ntxiv, machining, sib tsoo, thiab ua tiav.
Txheej / kev kho deg: Lub nplhaib dov los yog lub nplhaib ua tshuab tau coated, plated, peened, rooj plaub hardened.
Ua tiav ib feem: Lub nplhaib dov tsis tau raug kho cua sov, machined, hauv av, thiab nto kho kom tau raws li qhov yuav tsum tau ntawm cov neeg siv khoom kos duab thiab specifications.
Thaum tshav kub kub kho: Lub nplhaib dov tau raug kho cua sov xws li annealing, homogenization, quench thiab temper, los yog kev laus los txhim kho cov khoom siv thiab kev ua haujlwm.
Rough machined: Lub nplhaib dov tau ntxhib machined coj qhov khoob los ze zog mus rau qhov kawg geometry thiab tiav yuav tsum tau ua.
Daim ntawv thov
Hollow hlau rings yog siv raws li pib Tshuag los yog nyob ze net zoo blanks rau lub log los yog rail log tsheb, vaj tse, bearings, gears, valve rooj, nplhaib gaskets, thiab coupling. Cov ntawv thov uas muaj xws li:
Cov kabmob
Boiler qhov chaw
Flanges
Gears
Heavy phab ntsa couplings los yog connectors
Cov kav dej siab
Missile vaj tse
Cov twj tso kua mis
Reactor / siab hlab ntsha qhov chaw
Ntiv nplhaib gaskets
Valve rooj / plungers
Cov ntxhua khaub ncaws
