Impamvu zo kwangirika kwicyuma

1 Kubika bidakwiye, gutwara no guterura
Mugihe cyo kubika, gutwara no guterura, gusya ibyuma bitagira umwanda bizangirika mugihe bihuye nibishushanyo bivuye mubintu bikomeye, guhura nibyuma bidasa, ivumbi, amavuta, ingese nibindi byanduye. Kuvanga ibyuma bitagira umwanda hamwe nibindi bikoresho hamwe nibikoresho bidakwiye byo kubika birashobora guhumanya byoroshye hejuru yicyuma kandi bigatera kwangirika kwimiti. Gukoresha nabi ibikoresho byubwikorezi nibikoresho bishobora gutera ibisebe no gushushanya hejuru yicyuma kitagira umwanda, bityo bigasenya firime ya chromium hejuru yicyuma kitagira umwanda kandi ikabyara amashanyarazi. Gukoresha nabi kuzamura hamwe na chucks hamwe nigikorwa kidakwiye birashobora kandi gutuma firime ya chromium yo hejuru yibyuma bitangirika, bigatera kwangirika kwamashanyarazi.
2 Ibikoresho byapakurura no gukora
Ibikoresho by'ibyuma bizunguruka bigomba gutunganywa mubyuma kugirango bikoreshwe mu gufungura no gukata. Mubikorwa byavuzwe haruguru, firime ya chromium ikungahaye kuri okiside ya passiwasi hejuru yicyuma cyangiza ibyuma byangiritse kubera gukata, gufatana, gushyushya, gukuramo ibicuruzwa, gukonjesha gukonje, nibindi, bitera ruswa yamashanyarazi. Mubihe bisanzwe, ubuso bwerekanwe hejuru yicyuma nyuma ya firime ya passivation isenyutse bizitwara nikirere cyo kwikosora, kongera gukora firime ya chromium ikungahaye kuri oxyde passivation, kandi ikomeza kurinda substrate. Ariko, niba hejuru yicyuma kitagira umwanda kidafite isuku, bizihutisha kwangirika kwicyuma. Gukata no gushyushya mugihe cyo gutema no gufatana, gushyushya, gukuramo ibishishwa, gukora ubukonje bukomeye mugihe cyo gushinga bizatera impinduka zingana mumiterere kandi bitume amashanyarazi yangirika.
3 Shyushya
Mugihe cyo gukora ibyuma bitagira umuyonga, iyo ubushyuhe bugeze kuri 500 ~ 800 ℃, karbide ya chromium mu byuma bitagira umwanda izagwa ku mbibi z’ingano, kandi kwangirika hagati y’imiterere bizabera hafi y’urubibi rw’ibinyampeke bitewe no kugabanuka kwa chromium. Ubushyuhe bwumuriro wibyuma bya austenitike bidafite ingero zingana na 1/3 cyibyuma bya karubone. Ubushyuhe butangwa mugihe cyo gusudira ntibushobora gukwirakwira vuba, kandi ubushyuhe bwinshi bukusanyirizwa ahantu hasudutse kugirango ubushyuhe bwiyongere, bikaviramo kwangirika hagati yimiterere yicyuma kitagira ingese hamwe nuduce tuyikikije. Byongeye kandi, igice cya oxyde yo hejuru yangiritse, byoroshye gutera amashanyarazi. Kubwibyo, ahantu ho gusudira hakunze kwangirika. Igikorwa cyo gusudira kimaze kurangira, mubisanzwe birakenewe koza isura ya weld kugirango ikureho ivu ryirabura, spatter, slaging yo gusudira nibindi bitangazamakuru bikunda kwangirika, kandi kuvura no gutoranya passiyo bikorerwa kuri arc weld.
4. Guhitamo bidakwiye ibikoresho nibikorwa mugihe cyo gukora
Mubikorwa nyirizina, guhitamo nabi ibikoresho bimwe na bimwe no gukora inzira nabyo bishobora kuganisha kuri ruswa. Kurugero, gukuraho burundu passivation mugihe cyo gusudira gusudira bishobora gutera imiti yangirika. Ibikoresho bitari byiza byatoranijwe mugihe cyoza slag na spatter nyuma yo gusudira, bikaviramo isuku ituzuye cyangwa kwangiza ibikoresho byababyeyi. Gusya nabi kw'ibara rya okiside byangiza igice cya oxyde yo hejuru cyangwa gufatira ibintu byangiza ingese, bishobora gutera amashanyarazi.
