Excavator indobo umubiri hamwe nindobo amenyo yo gusudira no gusana uburyo bwubuhanga

Indobo yumubiri wibikoresho bya wY25 ni Q345, ifite gusudira neza. Indobo yinyo yindobo ni ZGMn13 (ibyuma bya manganese ndende), ikaba ari austenite yicyiciro kimwe mubushyuhe bwinshi kandi ikaba ifite ubukana bwiza hamwe no kwihanganira kwambara cyane bitewe nuburemere bitewe nakazi gakomeye kurwego rwo hejuru. Ariko ubu buryo bwo gusudira ibyuma burakennye: imwe iri muri welding yibasiwe nubushyuhe bwimvura ya karbide iterwa no kwinjiza ibintu; icya kabiri ni weld yamashanyarazi yamashanyarazi, cyane cyane mugace kegereye akarere kegeranye.

1.ubushuhe bwibasiwe na zone karbide yatewe na embrittlement
ZGMn13 ibyuma birebire bya manganese birashobora kugusha karbide kumupaka wingano mugihe yongeye gushyuha hejuru ya 250 ℃, kuburyo ubukana bwibikoresho bigabanuka cyane kandi imikorere myiza yicyuma kinini cya manganese yangiritse cyane. Nyuma yisesengura, mugihe ibyuma birebire bya manganese byongeye gushyuha kandi umuvuduko ukonje ukaba wihuse, karbide izabanza kugwa kumupaka wingano, kandi hamwe nigihe cyo gutura, karbide kumupaka wingano izahinduka kuva mubice bitarangiritse bihinduka meshi gukwirakwiza, n'ubugome bwayo biziyongera cyane. Kubwibyo, mugihe icyuma kinini cya manganese mugusudira cyangwa gushyuha nyuma yo gusudira, bizaba muri zone yo gusudira ubushyuhe bwibice byigice cyimvura ya karbide kurwego rutandukanye, kandi birashobora kuba impinduka ya martensitike, ntibitume gusa ibintu byoroha, ahubwo gabanya imyambarire yacyo no gukomera. Kandi, muri zone yibasiwe nubushyuhe byoroshye kugabanya ubushyuhe bwa karbide (650 ℃ cyangwa irenga) igihe kinini cyo gutura, niko imvura igwa.
Mu rwego rwo kugabanya imvura ya karbide no gukumira ibikoresho gutakaza ubukana no gucika intege, hagomba gufatwa ingamba zo kwihutisha ubukonje, ni ukuvuga kugabanya igihe cyo gutura ku bushyuhe bwinshi. Kubera iyo mpamvu, umurambo windobo hamwe n amenyo yindobo gusudira kugirango ukoreshe igice gito cyo gusudira, gusudira rimwe na rimwe, gusudira amazi, n'ibindi.

2.Gusudira kumashanyarazi
Irinde gucana amashyuza ni ukugabanya ibirimo S na P mubyuma fatizo cyangwa ibikoresho byo gusudira; Irashobora kandi gufata ingamba zo kugabanya guhangayikishwa no gusudira bivuye mubikorwa byo gusudira, nko gukoresha igice gito cyo gusudira, gusudira rimwe na rimwe, gusudira gutatanya no ku nyundo nyuma yo gusudira. Mu ndobo umubiri wuzuye hejuru yo gusudira ibyuma birebire bya manganese, urashobora kubanza gusudira igice cya Cr-ni, Cr-ni-Mn cyangwa Cr-Mn ibyuma bya austenitike kugirango umuyoboro wo gusudira wigunga, urashobora kwirinda gucika.

Excavator indobo umubiri hamwe nindobo yinyo yo gusudira

1.Imyiteguro mbere yo gusudira
Mbere ya byose, kura amenyo yindobo yambarwa mumubiri windobo, hanyuma ukoreshe urusyo rwa angle kugirango uhanagure ishyirwaho ryinyo yindobo isukuye, nta byondo, ingese, hanyuma urebe neza niba hari uduce nizindi nenge; fungura bevel hamwe na gaze ya carbone arc itegura amenyo yindobo kugirango usudwe, hanyuma usukure hamwe na gride ya angle.

2.Gusudira
① ubanza mumubiri windobo (hamwe nindobo yinyo yindobo) hamwe na GBE309-15 yo gusudira electrode yo gusudira hejuru, electrode yo gusudira igomba kuba 350 ℃, 15h yumisha mbere yo gusudira, umuyoboro wo gusudira ugomba kuba munini, umuvuduko wo gusudira utinda gato kugirango urebe ko fusion zone nikel irimo 5% kugeza 6%, kugirango ikumire umusaruro wa martensite yunvikana.
Kora imyanya yo gusudira. Nyuma y'amenyo y'indobo amaze guteranyirizwa hamwe, inkoni yo gusudira D266 ifite umurambararo wa 32MM ikoreshwa mu gusudira guhuza imyanya yo gusudira ku mpande zombi, uburebure bwa weld ntiburenga 30MM. gukonjesha amazi no ku nyundo ako kanya nyuma yo gusudira.
WGusudira hepfo. Koresha diameter ya 32MM D266 yo gusudira kugirango usudire. Koresha amashanyarazi make, DC ihindura polarite, gusudira rimwe na rimwe.
