Igihegusudira ibyuma, imikorere ya electrode igomba guhuza intego yicyuma kidafite ingese.Ibyuma bitagira umuyonga electrode igomba gutoranywa ukurikije icyuma fatizo nuburyo bukora (harimo ubushyuhe bwakazi, uburyo bwo guhuza, nibindi).
Ubwoko bune bwibyuma kimwe nibintu bivangavanze bikoreshwa
Ibyuma bitagira umwanda birashobora kugabanywamo ubwoko bune: Austenitike, martensitike, ferritic na biphase ibyuma bitagira umwanda, nkuko bigaragara mu mbonerahamwe ya 1.
Ibi bishingiye kumiterere yicyuma cyicyuma cyubushyuhe bwicyumba.Iyo ibyuma byoroheje bishyushye1550° F, imiterere ihinduka kuva mubyumba-ubushyuhe ferrite icyiciro kugeza austenitis icyiciro.Iyo ikonje, imiterere yicyuma yoroheje ihinduka ferrite.Imiterere ya Austenitike igaragara ku bushyuhe bwo hejuru ntabwo ari magnetique kandi ifite imbaraga nubukomezi burenze ibyumba-ubushyuhe bwa ferrite.
Nigute ushobora guhitamo ibikoresho byiza byo gusudira ibyuma?
Niba ibikoresho fatizo bisa, itegeko rya mbere ni "guhuza ibikoresho shingiro".Kurugero, hitamo ibikoresho byo gusudira kuri310 or 316ibyuma.
Kuri gusudira ibikoresho bidasa, igipimo cyo guhitamo ibikoresho fatizo hamwe nibintu byinshi bivangavanze birakurikizwa.Kurugero, niba 304 cyangwa 316 ibyuma bidafite ingese bisudwa, hitamo ubwoko316.
Ariko hariho na benshi badakurikiza ihame "rihuza ibikoresho fatizo" ryibihe bidasanzwe, noneho birakenewe "kugisha inama kumeza yo gutoranya ibikoresho".Kurugero, andika304ibyuma bidafite ingese nicyuma gikunze kuboneka, ariko nta Ubwoko304electrode.
Niba ibikoresho byo gusudira bihujwe nibikoresho fatizo, uburyo bwo guhitamo ibikoresho byo gusudira304ibyuma?
Iyo gusudira304ibyuma bidafite ingese, koresha ubwoko308gusudira ibikoresho, kuko ibintu byiyongereye muri308ibyuma bidafite ingese birashobora gutezimbere neza aho wasudira.
308L nayo ni amahitamo yemewe.L bisobanura karubone nkeya,3XXL ibyuma bitarimo ibyuma bya karubone ≤0.03%, hamwe nibisanzwe3XXibyuma bidafite ingese birashobora kubamo kugeza0.08%ibirimo karubone.
Kubera ko gusudira kwa L ari ubwoko bumwe bwo gutondekanya kimwe no gusudira kutari L, abayikora bagomba gutekereza cyane ku gukoresha imashini yo gusudira L kuko ibirimo karuboni nkeya bigabanya imyumvire yo kwangirika hagati y'isi (reba Ishusho 1).
Nigute ushobora gusudira ibyuma bidafite ingese nicyuma cya karubone?
Kugabanya ibiciro, inyubako zimwe zasuduye urwego rwo kurwanya ruswa hejuru yicyuma cya karubone.Mugihe cyo gusudira ibikoresho shingiro utabanje kuvanga ibintu hamwe nibikoresho fatizo hamwe nibintu bivangavanze, koresha ibikoresho byo gusudira hamwe nibintu byinshi bivangavanze kugirango uhuze igipimo cyo kugabanuka muri weld.
Iyo gusudira ibyuma bya karubone hamwe304 or 316ibyuma bitagira umwanda nibindi bidasa nicyuma (reba Imbonerahamwe 2),309Ibikoresho byo gusudirabigomba gusuzumwa kenshi.Niba ushaka kubona ibintu biri hejuru ya Cr, hitamo ubwoko312.
Ni ubuhe buryo bukwiye bwo gusukura mbere yo gusudira?
Mugihe cyo gusudira hamwe nibindi bikoresho, banza ukureho amavuta, ibimenyetso hamwe n ivumbi hamwe na chlorine idafite chlorine.Byongeye kandi, ikintu cya mbere ugomba kwitondera mugihe cyo gusudira ibyuma bitagira umwanda ni ukwirinda kwanduzwa nicyuma cya karubone kandi bikagira ingaruka ku kurwanya ruswa.Ibigo bimwe bibika ibyuma bitagira umwanda hamwe nicyuma cya karubone kugirango birinde kwanduzanya.Koresha uruziga rudasanzwe rwo gusya hamwe na bruwasi kugirango ibyuma bitagira umwanda mugihe usukura agace kegeranye.Rimwe na rimwe, ingingo ikenera gusukurwa ubugira kabiri.Kuberako ibikorwa byindishyi za electrode zo gusudira ibyuma bidafite ingorabahizi biragoye kuruta gusudira ibyuma bya karubone, gusukura hamwe ni ngombwa cyane.
