Ibiranga gusudira byibyuma bya STNentitle: Guhangayikishwa na plastike no guhangayikishwa mugihe cyo gusudira ni kinini, ariko bikonje cyane biragaragara. Nta karere kigoramye hamwe ningano zifunze mu myobo yasuye, bityo imbaraga za kanseri ya Weld ni hejuru.
Ibibazo nyamukuru byisumbuye ibyuma bidafite ibyuma: Guhindura amashusho menshi; Bitewe numupaka wacyo nibiranga hamwe nubwenge bumwe bwakarengane (s, p), biroroshye kubyara ibice bishyushye.
Ibibazo bitanu byisumbuye byo gusudira hamwe ningamba zo kuvura zinganda zidasanzwe
1. Gushiraho Carbide ya Chromium bigabanya ubushobozi bwingingo zisusurutsa kugirango barwanye ibicuruzwa bivanze.
Kugabanuka kw'ibicuruzwa bivanze: Ukurikije imitekerereze ya Chromium, kwanduza kaburimbo ya Chromium no kwibasirwa no gushyuha bishyuha kugeza ku bushyuhe bw'ubushyuhe bwa 450-850 ℃, bikaba bikaba bihamije imipaka ya chromium, bidahagije kugira ngo zinanire imbeba.
.
Mugabanye ibikubiye mucyuma fatizo no gusudira, ongeraho ibintu byiza ti, nb nibindi bintu bijya imbere kugirango ushyire imbere kugirango wirinde gushinga cr23C6.
b. Kora urubwize imiterere ibiri yimiterere ya austeteite na Ferrite ntoya. Iyo hari umubare munini wa Ferrite muri Weld, ibinyampeke birashobora kunonosorwa, ahantu h'ingano birashobora kwiyongera, kandi imvura ya charomide ya chromium kuri buri gice cya ?? Umupaka w'ingano urashobora kugabanuka. Chromium irashonga cyane muri Ferrite. CR23C6 ikorwa neza muri Ferrite idatera imipaka ya ausatentange ihingwa muri chromium; Ferrite ikwirakwira hagati ya austenite irashobora gukumira ruswa kumupaka wibinyampeke imbere ya diffusion.
c. Kugenzura igihe cyo guturamo ubushyuhe bwurugero. Hindura uruziga rusukura, gabanya igihe cyo gusiga 600 ~ 1000 ℃ bishoboka, hitamo ubushyuhe buto bwo gukonjesha, hanyuma uhitemo arc arc yongera igipimo cyo gukonjesha, hanyuma ukoreshe argon arc yongera urugero Ubuso bwa contactue hamwe na ruswa mugihe cyo gusudira nyinshi bigomba gusudira nkuko bisanzwe bishoboka.
d. Nyuma yo gusudira, kora umuti wakemurwa cyangwa gukomera (850 ~ 900 ℃) no gukonjesha ikirere kugirango usohoke kandi wihutishe diffusisiyo ya chromium).
(2) ruswa imeze nk'icyuma cyo gusudira. Kubera iyo mpamvu, ingamba zikurikira zo gukumira:
Bitewe nubushobozi bukomeye bwo guhagarika karubone, bizatandukanya imipaka y'ibinyampeke mu buryo bwo gukonjesha, mugihe Ti na NB biguma muri kristu yo gukanda. Iyo imyanzuro yongeye gushyuha mubushyuhe bwurugero, karubone yagereranijwe izacikamo muburyo bwa CR23C6 hagati ya kristu.
a. Gabanya ibikubiyemo bya karubone. Kubyuma bitagira ingano birimo ibintu bihamye, ibirimo bya karubone ntibigomba kurenga 0.06%.
b. Koresha inzira nziza. Hitamo intanga ntoya yo gusudira kugirango ugabanye igihe cyo guturamo ahantu heza ku bushyuhe bwinshi, kandi witondere kwirinda 'gukomera kwimikanya ubushyuhe. Iyo gusudira kabiri, gusudira mu rwego rwo hagati byangiza bikaba bisuye nyuma (Iyi niyo mpamvu yo gusudira imbere imiyoboro nini-irasumba hejuru yisumbuye). Niba bidashobora gushyirwa mubikorwa, uburyo buhebuje kandi bugaragaza uburyo buhebuje bugomba guhinduka kugirango twirinde ahantu heza hahuye na ruswa yongeye gukangurirwa no gushyuha.
c. Kuvura ahavugwa. Kora igisubizo cyangwa kuvura neza nyuma yo gusudira.
2. Stress CORROSIONE
Ingamba zikurikira zirashobora gukoreshwa kugirango wirinde imihangayiko kuneka indwara yabayeho:
a. Hitamo neza ibikoresho kandi uhindure ushyira mu gaciro. Icyuma-nickel-nikel austitic ibyuma, nickel ya chicon Umunyabwoba n'umuryango.
b. Kuraho cyangwa kugabanya imihangayiko isigaye. Kora ubushyuhe nyuma yo guhagarika ubushyuhe, kandi ukoreshe uburyo bwa manishi nko gusya, kurasa no kwitonda no gutonyuka kugabanya imihangayiko isigaye.
c. Igishushanyo gifatika. Kwirinda imihangayiko minini.
3. Gusudira bishyushye (Crystallsation Cracks muri Wels, imizigo ya Liquefaction muri zone yibasiwe nubushyuhe)
Imitini yo kuvuza ikirere cyane cyane biterwa nibigize imiti, imitunganyirize n'imikorere yibikoresho. Ni biroroshye gukora ahantu hato hamwe cyangwa ubumwe hamwe numwanda nka S na P. Gutandukanya Boron na Silicon bizateza imbere imyuka. Urubwibwe rworoshye gukora imiterere yinkingi ya Crystal hamwe nubuyobozi bukomeye, bufasha gutandukanya umwanda wangiza nibindi. Ibi biteza imbere gushinga film ikomeza amazi akomeza kandi atezimbere senseri yo guca imva. Niba gusudira bidashyushye kimwe, biroroshye gukora imihangayiko minini ya minini kandi itezimbere ibisekuru byo gusudira.
Ingamba zo gukumira:
a. Subiza neza ibikubiye mubyangiritse S na P.
b. Hindura imiterere yicyuma. Imiterere ibiri yo kwihatira urudomo rufite imbaraga nziza. Icyiciro cya Delta muri Welta kirashobora kunonosora ibinyampeke, bikuraho icyerekezo cyicyiciro kimwe cya Asupteur, kandi icyiciro cya Delta kirashobora guhungabanya imigenzo yangiza kandi bagagabanya ishyirwaho rya firime yimikorere yinyuma.
c. Hindura urubwize ibyuma. Appropriately increase the content of Mn, C, and N in the single-phase austenitic steel, and add a small amount of trace elements such as cerium, pickaxe, and tantalum (which can refine the weld structure and purify the grain boundary), which can reduce the sensitivity of thermal cracking.
d. Ingamba zo gutunganya. Mugabanye kwishyurwa cyane pisine yashongeshejwe kugirango wirinde gushiraho kristu yinkingi yinkingi. Koresha ubushyuhe buto hamwe nigituba gito cyambukiranya.
Kurugero, 25-20 Icyuma gikunze kugaragara mu mibo mit. Birashoboka kugabanya cyane ibintu byanduye hamwe nubunini bwibinyampeke byibikoresho, gufata uburyo bwo gutanga ingufu butanga ingufu, ibikoresho bito byinjiza kandi byongera igipimo gikonje cyingingo.
4. Kwangirika kwingingo zisuye
Ubushyuhe-Ibyuma Bikwiye Gutezimbere Inyabutumwa Byuzuye Inshingano zo gukumira injiji-ndende Ibyibato-ubushyuhe birasabwa kugira ubushyuhe buke-buke bwo gukumira ubushyuhe buke bwo kuvunika ingingo zisukuye.
5. Isuku nini igoreka
Kubera imyitwarire mike yubushyuhe hamwe nububiko bunini bwa kwaguka, gutangagura cyane ni binini, kandi clamps irashobora gukoreshwa mu gukumira imiterere.
Niba kandi ufite ibibazo byavuzwe haruguru, urashobora gusesengura ibintu witegereza inzira yo kuvura umuyoboro. Noneho fata ingamba zijyanye kugirango ukemure ikibazo ukurikije ibihe bihuye. Usibye ibintu bikubiye mubikoresho ubwabyo, ibuye, gukwirakwiza inkuta, ubukwirakwizwa, hamwe numuvuduko wo gusudira, urubwite rwumuyoboro wumuyoboro usudira ruzagira ingaruka zubunini buhebuje. Nka a Uwakoze abigize umwuga ibikoresho byo gutanga umusaruro winganda , ikaze kuvugana Hangao Tech nibibazo uhura nabyo mugukora imiyoboro isuye, kandi utegereze gutera imbere nawe.
