Forged rings yog cov khoom tseem ceeb uas tsim los tiv thaiv lub siab thiab cov khoom siv tshuab; Lawv tau dav siv hauv tshuab, piping flanges, bearing vaj tse, thiab lwm yam kev siv. Lawv cov txheej txheem tsim khoom feem ntau suav nrog kev npaj cov khoom siv raw, cua sov, forging, machining, thiab kev kho cua sov.
Kev npaj khoom siv
Forged rings feem ntau yog ua los ntawm cov qib siab - zoo carbon steel, alloy steel, los yog stainless hlau billets uas ua tau raws li cov tshuaj muaj pes tsawg leeg thiab cov cuab yeej cuab tam. Ua ntej pib tsim khoom, billets tau raug kuaj xyuas qhov ntev thiab kev tshuaj xyuas saum npoo kom ntseeg tau tias lawv tsis muaj kab nrib pleb, porosity, lossis kev suav nrog, yog li lav qhov zoo ntawm forging.
Cua sov
Ua ntej forging, lub billet yog rhuab mus rau qhov tsim nyog forging kub (feem ntau 1100-1250 degree, nyob ntawm seb cov khoom). Qhov no imparts zoo plasticity rau cov hlau, tso cai rau cov dej tsis sib xws thaum lub sij hawm tom qab tsim thiab txo cov kev ntxhov siab sab hauv thiab microstructural defects.
Forging
Forged rings tuaj yeem tsim los siv qhib - tuag forging lossis kaw - tuag forging txheej txheem. Qhib- tuag forging muaj qhov hloov tau yooj yim thiab tsim nyog rau me me -batch ntau lawm; lub nplhaib tseem ceeb profile tau ua tiav los ntawm kev rov ua dua, tig, thiab lub qhov- nthuav dav ua haujlwm. Kaw- tuag forging yog qhov zoo tshaj plaws rau kev tsim khoom loj, siv cov tuag tshwj xeeb los xyuas kom meej qhov tseeb thiab microstructural uniformity. Thaum lub sij hawm forging txheej txheem, lub puab thiab sab diameters yog maj mam tsim, thaum lub internal hlau qauv yog refined los txhim kho txhua yam khoom.
Tshuab dhos
Tom qab forging, cov rings feem ntau yog siv precision machining -xws li tig lub puab bore, txheej txoj kab uas hla, kawg lub ntsej muag, thiab sealing nto -kom paub meej qhov tseeb qhov ntev, concentricity, thiab flatness, yog li lub rooj sib tham tsim thiab installation specifications.
Kev kho cua sov
Kev kho cua sov yog ib theem tseem ceeb hauv kev tsim cov nplhaib forged. Cov txheej txheem xws li quenching thiab tempering, los yog normalizing, yog ua hauj lwm los txhim kho cov khoom hardness, lub zog, thiab toughness, nrog rau kev txhim kho hnav tsis kam thiab qaug zog. Kev kho cua sov tsis raug kho raws li kev ua haujlwm tshwj xeeb kom ntseeg tau tias lub nplhaib ua tau raws li qhov yuav tsum tau ua rau kev thauj khoom -cov kabmob, hnav tsis kam, lossis siab - qhov kub thiab txias.
Kev tshuaj xyuas thiab ntim
Thaum kawg, cov nplhaib forged tau txais kev tshuaj xyuas nruj heev- suav nrog kev kuaj xyuas qhov ntev, kev tshuaj xyuas qhov tsis xws luag, thiab qhov tsim nyog tsis yog - kuaj kev puas tsuaj (xws li kuaj ultrasonic thiab sib nqus particle). Thaum pom zoo, lawv tau txais kev tiv thaiv- xeb thiab ntim khoom kom muaj kev nyab xeeb thaum thauj thiab siv.
