Hariho uburyo icumi bukoreshwa muburyo bwo kuzimya ubushyuhe, harimo kuzimya kimwe (amazi, amavuta, umwuka); kuzimya kabiri; kuzimya icyiciro cya martensite; martensite amanota yo kuzimya munsi ya Madamu point; bainite isothermal Uburyo bwo kuzimya; uburyo bwo kuzimya uburyo; precooling uburyo bwo kuzimya isothermal; gutinda gukonjesha uburyo; kuzimya uburyo bwo kwikuramo; uburyo bwo kuzimya spray, nibindi.
1. Kuzimya uburyo bumwe (amazi, amavuta, umwuka) kuzimya
Kuzimya kimwe (amazi, amavuta, umwuka) kuzimya: Igikorwa cyashyutswe nubushyuhe bwo kuzimya kizimya muburyo bwo kuzimya kugirango gikonje burundu. Ubu ni bwo buryo bworoshye bwo kuzimya kandi bukoreshwa kenshi mubyuma bya karubone hamwe nibikoresho byibyuma bikora bifite ishusho yoroshye. Uburyo bwo kuzimya bwatoranijwe ukurikije coefficient de transfert yubushyuhe, gukomera, ingano, imiterere, nibindi byigice.
2. Kuzimya kabiri
Kuzimya kabiri-hagati: Igicapo cyashyutswe nubushyuhe bwo kuzimya kibanza gukonjeshwa kugirango cyegere umwanya wa Ms muburyo bwo kuzimya hamwe nubushobozi bukomeye bwo gukonjesha, hanyuma byimurirwa muburyo bwo gukonjesha buhoro buhoro kugirango bikonje kugeza ubushyuhe bwicyumba kugirango ugere kubukonje butandukanye ubushyuhe buringaniye kandi bifite igipimo cyiza cyo kuzimya igipimo cyo gukonjesha. Ubu buryo bukoreshwa kenshi mubice bifite imiterere igoye cyangwa ibihangano binini bikozwe mubyuma bya karubone nyinshi hamwe nicyuma. Ibikoresho bya karubone nabyo bikoreshwa kenshi. Ibitangazamakuru bikonjesha bikunze gukoreshwa birimo amavuta-amavuta, amazi-nitrate, amazi-umwuka, hamwe namavuta-mwuka. Mubisanzwe, amazi akoreshwa nkuburyo bwo kuzimya byihuse, naho amavuta cyangwa umwuka bikoreshwa nkuburyo bwo kuzimya buhoro. Ikirere gikoreshwa gake.
3. Kuzimya amanota ya Martensite
Kuzimya icyiciro cya Martensitike: ibyuma birasunikwa, hanyuma bigashyirwa mumazi meza (kwiyuhagira umunyu cyangwa kwiyuhagira alkali) hamwe nubushyuhe buri hejuru gato cyangwa munsi gato ugereranije na Martensite yo hejuru yicyuma, kandi bikagumaho mugihe gikwiye kugeza imbere imbere no imbere Ubuso bwinyuma bwibice byibyuma Nyuma yuko ibice bigeze ku bushyuhe buciriritse, birasohoka kugirango bikonje, kandi austenite irenze urugero ihinduka buhoro buhoro ihinduka martensite mugihe cyo kuzimya. Mubisanzwe bikoreshwa mubikorwa bito bifite imiterere igoye hamwe nibisabwa bikomeye byo guhindura ibintu. Ubu buryo kandi bukoreshwa muburyo bwo kuzimya ibyuma byihuta cyane hamwe nibikoresho byuma-byuma byinshi.
4. Uburyo bwo kuzimya Martensite amanota munsi ya Mme point
Uburyo bwo kuzimya bwa Martensite munsi ya Mme point: Iyo ubushyuhe bwo kwiyuhagira buri munsi ya Madamu wibyuma byakazi kandi birenze Mf, igihangano gikonjesha vuba mubwogero, kandi ibisubizo bimwe nkukuzimya amanota birashobora kuboneka mugihe ubunini ari bunini. Akenshi bikoreshwa mubyuma binini bikora hamwe no gukomera guke.
5. Uburyo bwa Bainite bwo kuzimya
Uburyo bwo kuzimya Bainite isothermal: Igice cyakazi kizimya mu bwogero hamwe nubushyuhe buke bwa bainite yicyuma na isothermal, kuburyo ihinduka rya bainite yo hepfo ibaho, kandi muri rusange ikabikwa mubwogero muminota 30 kugeza kuri 60. Inzira ya bainite austempering ifite intambwe eshatu zingenzi: ① kuvura ubuvuzi; ② kuvura nyuma yo gukonjesha; Treatment bainite isothermal treatment; bikunze gukoreshwa mubyuma bivangavanze, ibyuma bya karubone ndende ibice bito bito hamwe nu byuma byangiza.
6. Uburyo bwo kuzimya uburyo
Uburyo bwo kuzimya ibice: banza uzimye igicapo kugeza munsi ya Madamu kugirango ubone martensite hamwe nubunini bwa 10% kugeza 30%, hanyuma isotherm muri zone ya bainite yo hepfo kugirango ubone martensite na bainite kubikorwa binini byambukiranya ibice. Bikunze gukoreshwa Ibikoresho bya Alloy ibikoresho.
7. Uburyo bwo kuzimya hamwe nuburyo bwo kuzimya isothermal
Mbere yo gukonjesha uburyo bwo kuzimya isothermal: nanone byitwa gushyushya isothermal kuzimya, ibice byabanje gukonjeshwa mubwogero hamwe nubushyuhe buke (burenze Madamu), hanyuma bikimurirwa mubwogero hamwe nubushyuhe bwo hejuru kugirango austenite ihindurwe isothermal. Irakwiriye ibice byibyuma bifite ubukana buke cyangwa ibihangano binini bigomba gukenerwa.
8. Gutinda gukonjesha no kuzimya uburyo
Uburyo bwo kuzimya gukererwa gutinda: Ibice byabanje gukonjeshwa mbere yumuyaga, amazi ashyushye, cyangwa kwiyuhagira umunyu kugeza ku bushyuhe buri hejuru ya Ar3 cyangwa Ar1, hanyuma hagakorwa kuzimya icyarimwe. Bikunze gukoreshwa kubice bifite imiterere igoye hamwe nubunini butandukanye mubice bitandukanye kandi bisaba guhindura ibintu bito.
9. Uburyo bwo kuzimya no kwikuramo uburyo
Uburyo bwo kuzimya no kwikebesha: Igikorwa cyose kigomba gutunganywa kirashyuha, ariko mugihe cyo kuzimya, gusa igice kigomba gukomera (mubisanzwe igice cyakazi) cyinjizwa mumazi azimya hanyuma akonjeshwa. Iyo ibara ry'umuriro w'igice kitarimo gucika, uhite ubisohora mu kirere. Uburyo bwo kuzimya hagati. Uburyo bwo kuzimya no kwishishanya bukoresha ubushyuhe buva mu nsi idakonje rwose kugirango yimure hejuru kugirango igabanye ubuso. Ibikoresho bisanzwe bikoreshwa mukurwanya ingaruka nka chisels, punch, inyundo, nibindi.
10. Koresha uburyo bwo kuzimya
Koresha uburyo bwo kuzimya: Uburyo bwo kuzimya amazi aterwa kumurimo. Amazi atemba arashobora kuba manini cyangwa mato, bitewe nubujyakuzimu bukenewe. Uburyo bwo kuzimya spray ntabwo bukora firime hejuru yumurimo wakazi, bityo bigatuma igipande cyimbitse kuruta kuzimya amazi. Ahanini bikoreshwa mukuzimya hejuru.
