Cov ntaub ntawv hais txog tooj dag hlau
Cov pas nrig yog lub pas nrig ntawm cov khoom ua los ntawm kev sib tsoo ntawm tooj liab thiab zinc, thiab muaj npe rau nws cov xim daj. Muab tooj liab muaj 56% txog 68%, tooj dag muaj cov khoom siv zoo thiab hnav ua haujlwm, thiab siv tau los ua kev seev suab paj nruag, qhov chaw nkoj, thiab rab phom.
RBCuZn-A yog tooj hlau uas muaj me me ntawm tin. Melting point of about 900 ℃, molten metal muaj zoo fluidity, qaug zog thiab corrosion; feem ntau yog siv rau nplaim hluav taws, cua sov, thiab lwm txoj kev ntawm tooj liab, hlau thiab npib tsib xees, kuj siv tau tooj, tooj thiab nickel alloy Molten cov pa roj carbon dioxide ua haujlwm thiab cov siv roj hauv qhov nkev thaiv tawm.
RBCuZn-B yog ib txoj hlua hlau tooj hlau uas muaj me me ntawm cov hlau, cov xim silicon, manganese, thiab npib tsib xees. Melting point yog hais txog 880 ℃, cov hlau uas muaj hlau zoo txaus, thiab vim nws muaj silicon, cov evaporation ntawm zinc tau zoo suppressed. Nws tuaj yeem siv rau cov roj gas arc vuam thiab cov roj siv hluav taws xob tiv thaiv cov hlua, hlau, tooj hlau-tooj liab, grey cam khwb cia hlau, thiab cov cuab yeej siv tshuaj tua kab.
RBCuZn-C yog tooj hlau uas muaj me me ntawm cov hlau, tin, silicon, manganese thiab lwm yam. Taw melt yog li 860 ° C, qhov fluidity zoo dua, silicon tuaj yeem tswj tau cov evaporation ntawm zinc, tshem tawm cov porosity weld thiab muab cov khoom zoo txaus siab. Cov pa roj carbon dioxide-acetylene cov pa taws thiab cov qoob siv roj carbon fiber ntau li cov khoom siv. Tseem siv tau rau tooj tooj liab, hlau, tooj hlau tooj hlau, tooj hlau cam khwb cia hlau thiab cov cuab yeej siv hauv cav ntoo.
RBCuZn-D yog ib lub xaim hlau uas muaj txog 10% npib tsib xees. Melting point ntawm 935 ° C, qhov sib ntxiv ntawm nickel tsub kom muaj zog thiab toughness, Qhov tseem ceeb siv rau qhov ciaj ciam hlau, npib tsib tes thiab tawv hlau.
Siv Cov Lus Qhia
1.Care yuav tsum tau muab coj los txhuam cov hlua thiab lub hau ntawm cov hlau ua ntej welding.
2. Ua ntej welding, nws feem ntau yog preheated mus rau 400 ℃ mus rau 500 ℃ tom qab welding, oxyacetylene nplaim welding yuav tsum tau nruab nrog tooj liab roj flux thiab tooj liab brazing flux.
3. Lub nplaim nplaum yuav tsum siv lub nplaim nruab nrab lossis hluav taws me ntsis, tsim nyog txo qhov kub thaum lub sijhawm uas siv vuam voog, nce vuam ceev, thiab txo qhov chaw nyob ntawm lub pas dej sov siab kom txo cov evaporation thiab oxidation ntawm zinc.
