Kurapwa kwakashata kwekupisa kwepombi dzesimbi dzisina musono kunogona kukonzera nhevedzano yezvinetso zvekugadzira zviri nyore, zvichiita kuti kunaka kwechigadzirwa kuve kukanganiswa zvakanyanya uye kushandurwa kuita zvimedu.Kudzivisa zvikanganiso zvinowanzoitika panguva yekurapa kwekupisa zvinoreva kuchengetedza mari.Ndeapi matambudziko atinofanira kuisa pfungwa pakudzivirira panguva yekupisa kurapwa?Ngatitarisei matambudziko akajairika mukupisa kupisa kwepaipi isina musono simbi:
① Chimiro chepombi yesimbi isina kukwana uye kuita: zvinhu zvitatu zvinokonzerwa nekurapwa kusina kunaka kwekupisa (T, t, nzira yekutonhora).
Wei chimiro: Mbeu dzakakasharara A dzakaumbwa nesimbi pasi pemamiriro ekudziya kwepamusoro-soro inoumba chimiro umo maflakes F anogoverwa paP kana atonhodzwa.Icho chimiro chinopisa uye chinokuvadza kushanda kwese kwepombi yesimbi.Kunyanya, iyo yakajairika tembiricha simba resimbi inoderedzwa uye iyo brittleness inowedzera.
Iyo yakareruka W chimiro inogona kubviswa nekujairira pane yakakodzera tembiricha, nepo inorema W chimiro chinogona kubviswa nechipiri normalizing.Iyo yechipiri normalizing tembiricha yakakwira, uye yechipiri normalizing tembiricha yakadzikira.Makemikari zviyo.
Iyo FC chiyero dhayagiramu hwaro hwakakosha hwekugadzira tembiricha yekudziya yesimbi pombi kupisa kurapwa.Ndiyo zvakare hwaro hwekudzidza kuumbwa, metallographic chimiro, uye zvimiro zveFC makristasi mukuenzana, tembiricha yekuchinja dhizaini ye supercooling A (TTT dhayagiramu) uye inoenderera inotonhorera shanduko ye supercooling A. Chati (CCT chati) hwaro hwakakosha. yekugadzira tembiricha yekutonhora yekupisa kurapwa.
② Zviyero zvepombi yesimbi hazvina kukodzera: iyo dhayamita yekunze, ovality, uye curvature haisi kushivirira.
Kuchinja kwekunze kwekunze kwepombi yesimbi kunowanzoitika panguva yekudzima, uye dhayamita yekunze yepombi yesimbi inowedzera nekuda kwekushanduka kwehuwandu (kunokonzerwa nekuchinja kwemaitiro).Iyo saizi process inowanzowedzerwa mushure mekupisa maitiro.
Shanduko musimbi yepombi ovality: Migumo yepombi dzesimbi inonyanya kuhombe-dhayamita dzakatetepa-dzivirirwa pombi.
Simbi pombi kubhenda: kunokonzerwa nekupisa kusina kuenzana uye kutonhora kwepombi dzesimbi, zvinogona kugadziriswa nekutwasanuka.Kune mapaipi esimbi ane zvinodiwa zvakakosha, nzira inodziya yekururamisa (inenge 550 ° C) inofanira kushandiswa.
③Kutsemuka pamusoro pepombi dzesimbi: kunokonzerwa nekupisa kwakanyanya kana kumhanya kwekutonhora uye kunyanya kupisa kwemafuta.
Kuti uderedze kupisa kupisa kutsemuka mumapombi esimbi, kune rumwe rutivi, iyo yekudziya system uye inotonhora sisitimu yepombi yesimbi inofanira kugadzirwa maererano nemhando yesimbi, uye yakafanira yekudzima svikiro inofanira kusarudzwa;kune rumwe rutivi, iyo yakadzimwa simbi pombi inofanira kunyoroveswa kana kuti annealed nokukurumidza sezvinobvira kubvisa kushushikana kwayo.
④ Kukwenya kana kukuvadzwa kwakasimba pamusoro pepombi yesimbi: kunokonzerwa nekutsvedza kwehama pakati pepombi yesimbi neyeworkpiece, maturusi, uye rollers.
⑤Iyo pombi yesimbi ine oxidized, decarbonized, overheat, kana kupiswa.Zvakakonzerwa neT↑, t↑.
⑥ Surface oxidation yemapombi esimbi kupisa kunobatwa nekudzivirira gasi: Choto chekudziya haina kuvharwa zvakanaka uye mweya unopinda muchoto.Kuumbwa kwegasi revira hakuna kugadzikana.Izvo zvinodiwa kusimbisa kutonga kwehutano hwezvinhu zvose zvekupisa tube isina chinhu (simbi pombi).
