Kuzimya ni iki?
Kuzimya uburyo bwo kuvura ubushyuhe aho ibyuma birimo karubone ya 0.4% bishyushya kugeza 850T kandi bigakonja vuba.Nubwo kuzimya byongera ubukana, byongera n'ubugome.Ibitangazamakuru bizimya bikunze gukoreshwa birimo amazi yumunyu, amazi, amavuta yubutare, umwuka, nibindi. Kuzimya birashobora kunoza ubukana no kwambara birwanya ibikoresho byuma, kandi bikoreshwa cyane mubikoresho bitandukanye, ibishushanyo, ibikoresho byo gupima, nibice bidashobora kwambara (nka ibikoresho, ibizunguruka, ibice bya karubisi, nibindi).Muguhuza kuzimya hamwe nubushyuhe bwubushyuhe butandukanye, imbaraga numunaniro wicyuma birashobora kunozwa cyane, kandi guhuza iyi mitungo birashobora kugerwaho kugirango byuzuze ibisabwa bitandukanye.
Intego yo kuzimya ibyuma niyihe?
Intego yo kuzimya ni uguhindura austenite idakonje muri martensite cyangwa bainite kugirango ubone imiterere ya martensite cyangwa bainite, hanyuma ugafatanya nubushyuhe bwubushyuhe butandukanye kugirango utezimbere cyane ubukana, ubukana, kwambara, imbaraga zumunaniro, hamwe nubukomezi bwibyuma, bityo uhure nicyuma imikoreshereze itandukanye yibikoresho bya mashini zitandukanye.Birashoboka kandi guhura nibintu byihariye byumubiri nubumashini byibyuma bimwe na bimwe byihariye, nka ferromagnetism hamwe no kurwanya ruswa, binyuze mu kuzimya.
Kuzimya inshuro nyinshi ibyuma bya S45C
1. Kuzimya inshuro nyinshi bikoreshwa cyane mukuzimya ibice byibyuma byinganda.Nuburyo bwo gutunganya ubushyuhe bwibyuma butanga umubare munini wumuyaga uterwa hejuru yibicuruzwa byakozwe, bigashyushya byihuse ubuso bwigice, hanyuma bikazimya vuba.Ibikoresho byo gushyushya induction bivuga ibikoresho bya mashini bitera gushyushya ibihangano byo kuzimya hejuru.Ihame ryibanze ryo gushyushya induction: Igicuruzwa cyibicuruzwa gishyirwa muri inductor, ubusanzwe ni umuyoboro wumuringa udafite umwobo winjiza hagati cyangwa ingufu za AC nyinshi (1000-300000Hz cyangwa irenga).Igisekuru cyisimburangingo ya magnetiki itanga amashanyarazi aterwa numuyoboro umwe mubikorwa.Umuyoboro uterwa ukwirakwizwa ku buryo butaringaniye hejuru, ukomeye hejuru, ariko ugereranije imbere imbere, wegera 0 kuri centre.Ukoresheje iyi ngaruka yuruhu, ubuso bwakazi burashobora gushyuha byihuse, kandi mumasegonda make, ubushyuhe bwubuso burashobora kwiyongera byihuse kugera kuri 800-1000 ℃, hamwe no kwiyongera gake mubushyuhe bwo hagati.Ubuso bwo hejuru cyane bwibyuma 45 nyuma yo kuzimya inshuro nyinshi birashobora kugera kuri HRC48-53.Nyuma yo kuzimya inshuro nyinshi, kwihanganira kwambara nibikorwa biziyongera cyane.
Itandukaniro riri hagati yo kuzimya no kudazimya ibyuma 2.45: Hariho itandukaniro rikomeye hagati yicyuma cyazimye kandi kitazimye 45, cyane cyane ko ibyuma byazimye kandi bituje bishobora kugera ku gukomera gukomeye nimbaraga zihagije.Ubukomezi bwibyuma mbere yo kuzimya no gushyuha ni hafi ya HRC28, naho gukomera nyuma yo kuzimya no gutwarwa biri hagati ya HRC28-55.Mubisanzwe, ibice bikozwe muri ubu bwoko bwibyuma bisaba ibikoresho byiza byubukanishi, ni ukuvuga kugumana imbaraga nyinshi mugihe bifite plastike nziza nubukomere.
