Panyaya yekutonhorerwa kwe pombi dzesimbi dzekushongedza mukugadzira, izvo zvinodiwa zvehunyanzvi zvinoshandiswa pano zvakakwirira kwazvo.Semuenzaniso, kana tembiricha yekudzora isiri yakanaka, zvichikonzera chizvarwa che 316 kushushikana kwekushisa uye kushushikana kwechimiro, pombi yesimbi inogona kutsemuka kana kukanganisa.Tevere, Hangao Tech (SEKO Machina) ichaunza zvakadzama ruzivo rwekugadzira yekushongedza simbi mapaipi ekutonhodza:
Nekuda kwekugovaniswazve kwekunetsana kwemukati panguva yekugadziriswa, iyo yekushongedza yesimbi yesimbi chubhu ichave yakaremara, uye iko kurongeka kwekugadzirisa hakugone kuvimbiswa.Mukuwedzera, kubata zvikamu zvakakura zvinowanzoitika kune zvakasara kushungurudzika.Ese aya simbi isina tsvina yekushongedza machubhu anofanirwa kumisa kuzorora kwekushushikana mushure mekuita hutsinye.Kubviswa kwemukati kudzvinyirira annealing kunowanzo kushongedza simbi isina tsvina chubhu.Pa 500-550 ° C, yakamboshandiswa pakupisa kwemaminetsi makumi mashanu kusvika ku100, maawa matatu kusvika mashanu kana kupfuura (zvichienderana nenhamba yevira yakaiswa) kuchengetedza kushushikana kwemukati kwenguva yakareba.Inonzi kuchembera kwechisikigo, asi nzira iyi yakarebesa uye kazhinji haishandiswe.
Kana iyo simbi isina tsvina yekushongedza chubhu yakatonhodzwa, pamusoro uye zvimwe zvikamu zvitete zvinowanzoburitsa chena, yakaoma, brittle chena chimiro.Naizvozvo, akajairwa Stainless simbi yekushongedza machubhu anofanirwa kuvharirwa kana kumiswa kuti abvise kukanganisa kwekukanda.The annealing kana normalization tembiricha inonyanya pakati pe850 ne950°C.Iyo tembiricha inochengetwa kwemaawa 1-2, simenti inogadzirwa mugraphite uye austenite (danho rekutanga regraphitization).Yedu online inoenderera inopenya annealing choto inogona kukubatsira.Iyo haidi preheating, inogona kusvika kune yakakodzera annealing tembiricha mukati memasekonzi gumi mushure mekutanga.
Uyezve, yakabatana nePLC system, unogona kuona zvakananga iyo-chaiyo-nguva data, chaiyo-nguva yekutarisa kwemhepo, kuyerera kwemvura, tembiricha yekushanda, kumhanya.Munguva inotevera yekutonhora kwechoto, yechipiri cementite uye eutectoid cementite ichave yakagadzirwa mugraphite (kureva, chikamu chechipiri chegraphitization).Pakupedzisira, perlite inowedzerwa kune ferrite kana ferrite matrix kuderedza kuoma uye simba rekukanda.Uye zvakare, iyo simende process ndeye 850-950 ° C, asi iyo simenti muiyo standardization process, iyo inogona kuderedza nguva yekutonhora kwekuoma kweyekushongedza simbi yesimbi chubhu, inogona zvakare kuwana rimwe simba uye kuoma kwe pearlite matrix pamwe chete. .
