Qhov zoo ntawm Kev Siv Oxy-Acetylene Hardfacing Method
Qhov zoo ntawm Kev Siv Oxy-Acetylene Hardfacing Method
Qhov zoo tshaj ntawm txoj kev oxyacetylene yog hauv qab no:
Tsawg dilution ntawm weld deposit,
Kev tswj kom zoo ntawm cov nyiaj tso nyiaj,
Tsawg thermal shock vim cua sov qeeb thiab txias.
Cov txheej txheem oxyacetylene tsis pom zoo rau cov khoom loj.
Cov khoom siv roj vuam txheem yog siv rau hauv cov txheej txheem no.
Cov txheej txheem yog yooj yim. Txhua tus paub txog kev vuam dav dav yuav tsum tsis muaj teeb meem kev kawm nyuaj rau kev siv cov txheej txheem no.
Qhov saum npoo ntawm qhov yuav tsum tau ua kom tawv tawv yuav tsum tau ntxuav, tsis muaj xeb, nplai, roj, av, thiab lwm yam khoom txawv teb chaws. Preheat thiab tom qab cua sov ua hauj lwm kom txo tau cov kab nrib pleb tsim nyob rau hauv cov deposit los yog puag hlau.
Kev kho cov nplaim taws yog qhov tseem ceeb hauv txoj kev oxyacetylene. Ib qho acetylene feather ntau dhau yog pom zoo rau tso cov pas nrig nyuaj. Cov nplaim nruab nrab lossis cov qauv plaub yog tsim thaum cov pa oxygen rau acetylene piv yog 1: 1. Cov nplaim nplaim nplaim muaj ob ntu; ib lub hauv paus thiab ib lub hnab ntawv sab nraud. Thaum muaj ntau tshaj ntawm acetylene, muaj ib qho chaw thib peb, nruab nrab ntawm lub hauv paus thiab lub hnab ntawv sab nraud. Thaj chaw no yog hu ua acetylene feather. Ib qho acetylene feather ntau dhau yog peb zaug raws li lub khob sab hauv xav tau.
Tsuas yog qhov saum npoo ntawm lub hauv paus hlau nyob rau hauv tam sim ntawd yog ib qho nyuaj-faced yog coj mus rau lub melting kub. Cov nplaim taws yog ua si rau saum npoo ntawm cov khoom kom tawv-ntsej muag, ua kom lub taub hau ntawm lub khob hliav qab tsuas yog tshem tawm ntawm qhov chaw. Ib qho me me ntawm cov pa roj carbon monoxide yog absorbed rau hauv qhov chaw, txo nws cov melting point thiab ua ib tug watery, glazed tsos hu ua 'hws'. Cov pas nrig nyuaj yog nkag mus rau hauv cov nplaim taws thiab ib qho me me me me yaj tawm mus rau qhov chaw tawm hws, qhov chaw nws kis tau sai thiab huv si, zoo ib yam li cov hlau nplaum.
Tom qab ntawd tus pas nrig nyuaj yog melted thiab kis mus rau saum npoo ntawm lub hauv paus hlau. Cov khoom siv tawv tawv yuav tsum tsis txhob sib xyaw nrog lub hauv paus hlau, tab sis yuav tsum tau khi nrog qhov chaw kom dhau los ua cov txheej txheem tshiab. Yog hais tias ntau dhau dilution tshwm sim, cov khoom ntawm cov khoom siv tawv tawv yuav degraded. Qhov saum npoo dhau los ua cov txheej txheem tshiab tiv thaiv. Yog hais tias ntau dhau dilution tshwm sim, cov khoom ntawm cov khoom siv tawv tawv yuav degraded.
Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
