Njira zisanu ndi zitatu zodzitetezera pakuwotcherera zitsulo zosapanga dzimbiri

1. Chitsulo chosapanga dzimbiri cha Chromium chimakhala ndi kukana kwa dzimbiri (ma oxidizing acid, organic acid, cavitation), kukana kutentha, komanso kukana kuvala. Nthawi zambiri amagwiritsidwa ntchito pazinthu zamagetsi monga magetsi, mankhwala, ndi mafuta. Chitsulo chosapanga dzimbiri cha Chromium chimakhala ndi kuwotcherera koyipa, ndipo chidwi chiyenera kulipidwa ku njira zowotcherera, zinthu zochizira kutentha, ndi zina zambiri.

2. Chitsulo chosapanga dzimbiri cha Chromium 13 chimakhala ndi zowumitsa zowotcherera kwambiri ndipo sachedwa kusweka. Ngati mtundu womwewo wa chromium zosapanga dzimbiri zitsulo kuwotcherera ndodo (G202, G207) ntchito kuwotcherera, preheating pa 300 ℃ kapena pamwamba ndi pang'onopang'ono kuzirala mankhwala padziko 700 ℃ pambuyo kuwotcherera ziyenera kuchitika. Ngati mbali zowotcherera sizingathe kuthandizidwa ndi kutentha kwa post weld, ndodo za chromium nickel zosapanga dzimbiri (A107, A207) ziyenera kugwiritsidwa ntchito.

3. Chromium 17 chitsulo chosapanga dzimbiri chimakhala ndi weldability wabwinoko kuposa chromium 13 chitsulo chosapanga dzimbiri powonjezera zinthu zoyenera zokhazikika monga Ti, Nb, Mo, ndi zina zambiri. Pamene ntchito mtundu womwewo wa chromium zosapanga dzimbiri kuwotcherera ndodo (G302, G307), preheating pa 200 ℃ kapena pamwamba ndi kutentha mankhwala pa kuzungulira 800 ℃ pambuyo kuwotcherera ziyenera kuchitika. Ngati mbali zowotcherera sizingathe kutenthedwa, ndodo za chromium nickel zosapanga dzimbiri (A107, A207) ziyenera kugwiritsidwa ntchito.

Pa kuwotcherera kwa chromium nickel chitsulo chosapanga dzimbiri, kutenthetsa mobwerezabwereza kumatha kuyambitsa ma carbides, kuchepetsa kukana kwake kwa dzimbiri komanso makina ake.

5. Ndodo zowotcherera zitsulo za chromium nickel zili ndi kukana kwa dzimbiri komanso kukana kwa okosijeni, ndipo zimagwiritsidwa ntchito kwambiri popanga mankhwala, feteleza, mafuta, ndi makina azachipatala.

6. Chromium nickel zosapanga dzimbiri zokutira zili ndi titaniyamu calcium mtundu ndi otsika wa haidrojeni mtundu. Mtundu wa calcium wa titaniyamu ukhoza kugwiritsidwa ntchito powotcherera AC ndi DC, koma kuya kwake kumakhala kosazama panthawi yowotcherera ndi AC ndipo kumakonda kufiira. Chifukwa chake, magetsi a DC ayenera kugwiritsidwa ntchito momwe angathere. Diameter 4.0 ndi pansi angagwiritsidwe ntchito kuwotcherera onse udindo, pamene awiri 5.0 ndi pamwamba angagwiritsidwe ntchito kuwotcherera lathyathyathya ndi fillet kuwotcherera.

7. Ndodo zowotcherera ziyenera kukhala zowuma mukamagwiritsa ntchito. Titaniyamu kashiamu mtundu ayenera zouma pa 150 ℃ kwa ola 1, ndi otsika wa haidrojeni mtundu ayenera zouma pa 200-250 ℃ kwa ola 1 (kubwereza kuyanika sikuloledwa, apo ayi ℃ ℃ sachedwa kusweka ndi peeling), kuteteza ℃ ℃ ℃ mobwerezabwereza. wa ndodo yowotcherera kuchokera kumamatira mafuta ndi dothi lina, kuti musawonjezere mpweya wa weld ndi kukhudza khalidwe la welded gawo.

Pofuna kupewa dzimbiri pakati pa granular chifukwa cha kutentha, kuwotcherera pakali pano sikuyenera kukhala kokwera kwambiri, pafupifupi 20% kuchepera kuposa ndodo za carbon steel. Arc sayenera kutalika kwambiri, ndipo inter-wosanjikiza ayenera utakhazikika mwamsanga. Mikanda yopapatiza yowotcherera imakondedwa.
