Ni ubuhe buryo bwo Kwirinda Ibishishwa bitagira umuyonga Iyo bikonje?

Kubyerekeranye no gukonjesha kwa gushushanya ibyuma bidafite ibyuma muburyo bwo gukora, ibisabwa bya tekiniki bikoreshwa hano ni hejuru cyane.Kurugero, niba kugenzura ubushyuhe atari byiza, bikavamo kubyara 316 yumuriro nubushyuhe bwimiterere, umuyoboro wibyuma urashobora gucika cyangwa guhinduka.Ibikurikira, Tekinoroji ya Hangao (Imashini ya SEKO) izatangiza mu buryo burambuye ubumenyi bwo gukora imiyoboro idashushanyijeho ibyuma yo gukonjesha:

Bitewe no kugabanganya impagarara zimbere mugihe cyo gutunganya, umuyoboro wicyuma utagira umuyonga uzahinduka, kandi gutunganya neza ntibishobora kwemezwa.Byongeye kandi, gukoresha ibice binini bikunda guhangayikishwa cyane.Ibi byuma byose bidafite ingese bigomba guhagarika imihangayiko nyuma yo gukora nabi.Gukuraho impagarara zimbere ni ugushushanya umuyoboro wibyuma.Kuri 500-550 ° C, mbere yakoreshwaga mubushyuhe bwicyumba muminota 50 kugeza 100, amasaha 3 kugeza kuri 5 cyangwa arenga (bitewe numubare w’itanura ryashyizweho) kugirango ugumane impagarara imbere mugihe kirekire.Byitwa gusaza bisanzwe, ariko ubu buryo ni burebure kandi mubisanzwe ntibukoreshwa.

Iyo umuyoboro wo gushushanya ibyuma bidafite ingese ukonje, ubuso hamwe nibice bito byoroheje bitanga umusaruro wera, ukomeye, ucagaguye.Kubwibyo, ibyuma bisanzwe bidafite ingese bigomba gushyirwaho cyangwa gushyirwaho kugirango bikureho inenge.Ubushyuhe bwa annealing cyangwa busanzwe buri hagati ya 850 na 950 ° C.Ubushyuhe bugumaho amasaha 1-2, simaite ikomatanyirizwa muri grafite na austenite (icyiciro cya mbere cyo gushushanya).Iwacu kumurongo uhoraho urumuri rwa annealing itanura irashobora kugufasha.Ntabwo ikeneye gushyuha, irashobora kugera kubushyuhe bwiza bwa annealing mumasegonda 10 nyuma yo gutangira.

Byongeye kandi, ihujwe na sisitemu ya PLC, urashobora kubona mu buryo butaziguye amakuru nyayo, kugenzura igihe nyacyo cyumuvuduko wikirere, umuvuduko wamazi, ubushyuhe bwakazi, umuvuduko.Mugihe gikurikira cyo gukonjesha kwitanura, cementite ya kabiri na eutectoid cementite bizahuzwa muri grafite (nukuvuga icyiciro cya kabiri cyo gushushanya).Hanyuma, perlite yongewe kuri ferrite cyangwa ferrite kugirango igabanye ubukana nimbaraga za casting.Byongeye kandi, inzira ya sima ni 850-950 ° C, ariko simaite mugikorwa gisanzwe, gishobora kugabanya igihe cyo gukonjesha ubukana bwumuringoti wicyuma utagira umuyonga, birashobora kandi kubona imbaraga nubukomere bya matrike ya pearlite hamwe .
