Irembo rya valve ibikoresho fatizo bidafite ibyuma byo gusudira

Irembo rya valve ibikoresho fatizo bidafite icyuma cyo gusudira Iki cyuma gisanzwe Icyuma gisanzwe cyerekana ibyuma, ibipimo bya tekiniki, uburyo bwo gupima nuburyo bwo gupima nandi makuru ajyanye nayo. Ibipimo ngenderwaho bikoreshwa mubyuma bya electrode idafite ibyuma byo gusudira arc. Ibyo byuma bya electrode byambaye bigomba kuba birimo chromium irenga 10,50% hamwe nicyuma kirenze ikintu icyo aricyo cyose. Ukurikije ibice byibyuma byahujwe, ubwoko bwingenzi bwo gusudira, umwanya wo gusudira nubwoko bwumudozi wo gusudira, inkoni yo gusudira ntigomba kugira inenge nkibice, ibibyimba, ibisigara no kugwa byangiza ubuziranenge bwa weld, nkuko bigaragara mu mbonerahamwe ya 1 nimbonerahamwe. 2 Ibipimo ngenderwaho bikoreshwa mubyuma bya electrode idafite ibyuma byo gusudira arc. Ibyo byuma bya electrode byambaye bigomba kuba birimo chromium irenga 10,50% hamwe nicyuma kirenze ikintu icyo aricyo cyose. 2 Ibipimo ngenderwaho GB223.1 ~ 223.70 Uburyo bwo gusesengura imiti y’ibyuma na aluminiyumu GB1954 - Gupima ibintu bya microstructure mu gusudira ibyuma bya chrome-nikel bito bito bito GB2652 Uburyo bwo gupima Tensile yo gusudira no kwambika ibyuma GB 4334.5 Ibyuma bitagira umuyonga - Ikizamini cya ruswa uburyo bwa sodiumi thiosulfate hydrochloride 3 Ubwoko no gutondekanya ibyiciro 3.1 Ubwoko nibisobanuro byinkoni yo gusudira bigomba kugabanywa ukurikije ibice byuma byahujwe, ubwoko bwimikorere yo gusudira, umwanya wo gusudira nubwoko bwumudugudu. 3.2 Uburyo bwo gutegura icyitegererezo Icyitegererezo "Inyuguti" yerekana electrode, naho umubare nyuma ya "E" ugereranya umubare wibyiciro byicyuma gishongeshejwe. Niba hari ikintu cyihariye gisabwa kubigize, ibice byerekanwa nikimenyetso cyimiti nyuma yumubare. Imibare ibiri nyuma ya "imwe" yerekana ubwoko bwa electrode yibanze, gusudira hamwe nubwoko bwubu. 3.3 Ingero zo gusudira inkoni zisobanutse muriki gipimo nizo zikurikira: ④E502, E505, E7Cr, E5Mo, E9Mo yo mu bwoko bwa electrode izashyirwa mubikurikira byahinduwe na GB5118 "high alloy Steel electrode", ariko bisibwe kuriki gipimo. ⑤ Umugereka umwe XX. Yerekana imwe 15, imwe 16, imwe 17, imwe 25 cyangwa imwe 26. Icyitonderwa: gusudira-umwanya wuzuye ntabwo byemewe kuri electrode ifite diameter ingana na 5.0mm. 4 Ibipimo bya tekiniki 4.1 Ibisobanuro 4.1.1 Ibisobanuro bya electrode bigomba kuba byujuje ibisabwa mu mbonerahamwe ya 3. 4.1.1.1 Emerera gukora electrode ya 3.0mm ya aperture aho kuba 3.2 electrode na 5.8mm ya elegitoronike aho kuba 6.0rnm electrode. 4.1.1. 4.2 Core yo gusudira 4.2.1 Ntihakagombye kubaho ibice, ibibyimba, ibisigara no kugwa mumasoko yo gusudira ya electrode yangiza ubwiza bwa weld. 4.2.2. Intangiriro yagaragaye ya electrode igomba kuba yujuje ibi bikurikira: a. Diameter yo hanze ya electrode ntishobora kurenga mm 2,2, kandi uburebure bwimbere bwagaragaye ntibushobora kurenga 1,6mm b. Diameter ya electrode ni 2,5mm na 3.2mm, kandi uburebure bwimbere bwagaragaye ntibugomba kurenza 2.0mm muburebure bwa Angle c. Diameter ya electrode irenga 3.2mm, kandi uburebure bwimbere yibanze ku burebure Inguni ntigomba kurenza 3.2mm d. Ubwoko bwose bwa electrode aperture kuruhande rwuruziga ntigomba kurenza kimwe cya kabiri cyuruziga. 4.2.3 Intandaro ya electrode igomba kugira imbaraga zihagije zo kwikuramo kugirango birinde kurimbuka mu gutwara cyangwa gukoresha bisanzwe. 4.2.4 Electrode eccentricity igomba kuba yujuje ibi bikurikira: a. Diameter yo hanze ya electrode ntishobora kurenga 2.5rnm, kandi eccentricity ntishobora kurenga 7%; b. Diameter ya 3.2mm na 4.0mm electrode, eccentricity ntigomba kurenza 5%; c. Ubushuhe bwa electrode ntibushobora kuba munsi ya 5.0mm, kandi eccentricity ntishobora kurenza 4%. Uburyo bwo kubara bwa eccentricity bwerekanwe kuburyo bukurikira (Ishusho 1). Muri formula: T1 - gusudira inkoni yambukiranya igice cyitwikiriye igipande ** kinini kinini cyoroshye cyogosha cyibanze cya aperture T2 - ntoya yoroheje kandi yinini ya weld yibanze ya aperture yumutwe umwe epidermal layer 4.3 T-gufatanya gusudira 4.3.1 Ubuso bwo gusudira bugomba kugenzurwa namaso yabantu adafite ibice, inkovu zo gusudira, gusudira imyobo hamwe nu mwobo wo hejuru. 4.3.2. b. Ingano yamaguru ya buri ruhande irasudira kandi itandukaniro riri hagati yuburebure bwibyobo bibiri byo gusudira bigomba guhuza nibisobanuro biri mu mbonerahamwe ya 5 (nkuko bigaragara ku gishushanyo 2). c. Ubwumvikane bwa buri mwirondoro weld bugomba kuba bujuje ibisabwa mu gishushanyo 3. d. Reba n'amaso yabantu, ntihakagombye kubaho gucikamo ibice byambukiranya weld. e. Nta gusudira cyangwa gusiba ikirere. 4. gikemutse, hakurikiraho gukonjesha ikirere kugeza ubushyuhe bwicyumba. f. Icyitegererezo gikingiwe kuri 740 ~ 760 ℃ kuri 4 h, hagakurikiraho gukonjesha ikirere. g. Icyitegererezo cyashyizwe kuri 730 ~ 750 ℃ ​​kuri 4 h, hakurikiraho gukonjesha ikirere. 4.6 Kurwanya ruswa yicyuma cyahujwe Ikizamini cyo kurwanya ruswa cyuma cyahujwe kigomba kugaragazwa namasezerano yimpande zombi. 4,7 ihuze n'ibisabwa mu mbonerahamwe ya 7. Mbere yubushakashatsi, electrode igomba gutekwa ukurikije ubushyuhe bwumye bwatangijwe nuwabikoze. Birakwiriye gutumanaho AC cyangwa DC gusudira electrode igerageza guhitamo itumanaho AC. Ibikoresho fatizo bikoreshwa mu gusesengura imiti bishobora kuba ibyuma bya karubone, ibyuma binini cyane cyangwa icyuma kidafite ingese. Ibirimo bya karubone byuma byahujwe ntibishobora kurenga 0,04% ya electrode kandi ibikoresho fatizo bikoreshwa mu gusesengura imiti ya electrode ya E63O bifite karubone nyinshi cyane ya 0.03%. Dukurikije ibivugwa mu ngingo ya 5.4.3, ibikoresho fatizo bifite karubone nyinshi cyane ya 0,25% nabyo birashobora gukoreshwa. Ibyuma fatizo byo gusesengura imiti ya electrode ni karuboni nyinshi cyane ya 0,25% ... Guhuza: Icyuma cyo gusudira icyuma cyo gusudira ibikoresho byo mu irembo ryibikoresho fatizo (1) 5 Uburyo bwikizamini 5.1 Ikizamini cya electrode ya buri bwoko nibisobanuro igomba kubahiriza ibisabwa mu mbonerahamwe ya 7. Mbere yubushakashatsi, electrode igomba gutekwa ukurikije ubushyuhe bwumye bwatangijwe nuwabikoze. Birakwiriye gutumanaho AC cyangwa DC gusudira electrode igerageza guhitamo itumanaho AC. Imbonerahamwe 7 Amabwiriza yubushakashatsi 5.2 Ibikoresho shingiro byubushakashatsi 5.2.1 Ibikoresho fatizo byo gupima T-gufatanya gusudira bisobanuwe ku buryo bukurikira: Ubwoko bwa Austenitike nubwoko bwa E630 bwo gusudira bugomba gukoresha icyuma kidafite ingese hamwe nicyuma cyahujwe, cyangwa 0Cr19Ni9 cyangwa OCr19Ni9Ti isahani yuzuye. B.410, E410IiNMo E430 ubwoko bwa electrode igomba kuba OCr13, cyangwa ubwoko bwa 1Cr13 bwicyuma. c. Ubundi bwoko bwinkoni zo gusudira bugomba kuba bukozwe mubyuma birwanya ubushyuhe cyangwa ibyuma bya karubone cyangwa ibyuma biciriritse byibyuma bifite ibice bimwe nicyuma cyahujwe. 5.2.2. Ibirimo bya karubone byuma byahujwe ntibishobora kurenga 0,04% ya electrode kandi ibikoresho fatizo bikoreshwa mu gusesengura imiti ya electrode ya E63O bifite karubone nyinshi cyane ya 0.03%.
