Daim ntawv thov ntawm PAG hauv kev kho cua sov ntawm 50CrVA nplooj ntoos hlav
50CrVA steel belongs rau Cr-V series caij nplooj ntoos hlav steel. Nws muaj kev tiv thaiv zoo rau decarburization thiab muaj peev xwm tiv thaiv austenite grain coarsening. Tom qab kev kho cua sov, nws muaj kev txwv siab elastic, lub zog txwv thiab zoo plasticity. Nws yog dav siv nyob rau hauv Automobile nplooj caij nplooj ntoos hlav manufacturing. Raws li lub peev xwm thauj khoom ntawm cov tsheb thauj khoom hnyav hauv tsev tau nce los ntawm 4t yav dhau los mus rau ntau dua 40t tam sim no, thaum 50CrVA steel siv rau hauv lub tsheb nplooj hlav, qhov hla ntu tuab yuav tsum tau nce los ntawm 8mm mus rau 24mm thiab siab dua. Txawm li cas los xij, kev kho cua sov ib txwm siv ntawm 50CrVA steel Thaum lub sijhawm ua haujlwm, qhov nruab nrab quenching siv yog cov roj quenching zoo tib yam, thiab qhov tseem ceeb quenching phaj thickness rau roj quenching yog 24 hli. Los ntawm kev txheeb xyuas ntawm ntau qhov kev puas tsuaj ntawm cov khoom siv hluav taws xob kho 50CrVA cov nplooj hlav thiab kev tshawb fawb ntawm cov txheej txheem zoo ntawm qhov chaw tsim khoom, nws tau pom tias thaum qhov hla ntu tuab yog ze rau lossis ntau dua qhov tseem ceeb quenching phaj thickness. ntawm cov roj quenching, ib txwm quenching tsis tuaj yeem tshwm sim, cuam tshuam rau cov khoom siv hluav taws xob thiab cov phaj hlau. Lub neej qaug zog ntawm lub caij nplooj ntoos hlav. Dej-soluble quenching nruab nrab - PAG, raws li hom tshiab ntawm quenching nruab nrab, tau siv los ntawm ntau thiab ntau cov kws tshawb fawb txog kev kho cua sov vim nws qhov zoo xws li kev ua kom txias txias, kev siv ntau yam, kev ua kom tawv nqaij, kev tiv thaiv ib puag ncig, tsis muaj kuab paug, thiab hluav taws kub txaus ntshai. nyiam. Kab lus no siv PAG dej-soluble quenching nruab nrab thiab zoo tib yam quenching roj kom sov kho 24 hli tuab 50CrVA cov ntaub ntawv nplooj springs, thiab kawm cov metallographic qauv, hardness thiab qaug zog lub neej ntawm reed tom qab kev kho cua sov.
A 50CrVA cov ntaub ntawv reed raug xaiv los ua cov khoom siv kho cua sov. Nws specification yog 500mm × 9{{10}}mm × 24mm. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov khoom siv kuaj yog (ntau seem, %): 0.53C, 0.011S, 0.009P, 0.70Mn, 0.27Si, 0.99Cr, 0.12 V, qhov seem yog Fe . Nyob rau hauv cov xwm txheej ntawm cov txheej txheem kev kho cua sov (900 degree ± 5 degree rau 20 feeb), cua sov thiab rwb thaiv tsev yog nqa tawm los ntawm lub tshuab hluav taws xob quenching, thiab qee qhov concentration ntawm cov dej-soluble quenching nruab nrab thiab cov roj quenching zoo tib yam yog siv rau quenching. , thiab ces nias rau (480 ± 5) degree Thaum tshav kub kub preservation rau 120 feeb, dej txias thiab tempering, thiab tau txais cov qauv tom qab kev kho cua sov nrog txawv quenching xov xwm.
Siv PAG dej-soluble quenching nruab nrab es tsis txhob siv cov roj quenching zoo tib yam, 24mm tuab 50CrVA cov ntaub ntawv nplooj nplooj hlav qauv tau ua tiav kev kho cua sov, thiab tsis muaj cov kab nrib pleb tau pom los ntawm kev tshuaj xyuas cov khoom sib nqus. Siv PAG dej-soluble quenching nruab nrab rau tshav kub-kho ib 24 hli tuab 50CrVA cov ntaub ntawv nplooj caij nplooj ntoos hlav qauv, lub quenched thiab tempered metallographic qauv thiab hardness yog zoo dua li cov qauv tshav kub-kho nrog zoo tib yam quenching roj. Qhov nruab nrab qaug zog lub neej ntawm 24 hli tuab 50CrVA cov ntaub ntawv nplooj nplooj hlav qauv tom qab kev kho cua sov nrog PAG dej-soluble quenching nruab nrab tuaj yeem ncav cuag ntau dua 150, 000 zaug. Piv nrog rau cov qauv quenching roj kub kho cov qauv, lub neej qaug zog yog ze li ob npaug, uas ua rau lub neej qaug zog zoo heev. Zoo ntawm nplooj springs.
