Chromium-zirconium mkuwa (CuCrZr)

Chromium-zirconium copper (CuCrZr) ndiye chinthu chomwe chimagwiritsidwa ntchito kwambiri ndi ma elekitirodi pakuwotcherera kukana, komwe kumatsimikiziridwa ndi mankhwala ake abwino komanso thupi komanso mtengo wake wabwino.

1. Elekitirodi yamkuwa ya chromium-zirconium yakwaniritsa bwino bwino zizindikiro zinayi zogwirira ntchito za electrode yowotcherera:

☆ Maduidwe abwino kwambiri - - kuonetsetsa kuti gawo la kuwotcherera limakhala locheperako ndikupeza mtundu wabwino kwambiri wowotcherera ☆Kutentha kwamakina apamwamba kwambiri - kutentha kwapang'onopang'ono kumatsimikizira magwiridwe antchito ndi moyo wa zida zamagetsi m'malo otentha kwambiri.

☆ Abrasion resistance——electrode si kophweka kuvala, kutalikitsa moyo ndi kuchepetsa mtengo ☆ Higher kuuma ndi mphamvu - kuonetsetsa kuti elekitirodi mutu si kophweka deform ndi kuphwanya pamene ntchito pansi pa mavuto, ndi kuonetsetsa kuwotcherera khalidwe

2. Elekitirodi ndi mtundu wa consumable mu kupanga mafakitale, ndipo kumwa ndi lalikulu, kotero mtengo wake ndi mtengo ndi chinthu chofunika kuganizira. Poyerekeza ndi ntchito yabwino kwambiri ya electrode yamkuwa ya chromium-zirconium, mtengo wake ndi wotchipa ndipo ungathe kukwaniritsa zofunikira zopanga.

3. Chromium-zirconium maelekitirodi amkuwa ndi oyenera kuwotcherera mawanga ndi kuwotcherera kwa mbale zazitsulo za kaboni, mbale zachitsulo zosapanga dzimbiri, mbale zokutira ndi mbali zina. Zipangizo zamkuwa za Chromium-zirconium ndizoyenera kupanga zisoti zama electrode, ndodo zolumikizira ma elekitirodi, mitu yamagetsi, ma electrode grips, ndi ma elekitirodi apadera opangira kuwotcherera, gudumu lowotcherera, nsonga yolumikizirana ndi magawo ena amagetsi. ndi

Mutu wamba wa elekitirodi, kapu ya elekitirodi, ndi ma elekitirodi a amuna kapena akazi okhaokha opangidwa amatengera ukadaulo wozizira wowonjezera komanso makina olondola kuti achulukitse kachulukidwe kazinthuzo, ndipo magwiridwe antchito ake ndiabwino kwambiri komanso olimba, kuwonetsetsa kukhazikika kwa kuwotcherera.

2. Beryllium Copper (BeCu)

Poyerekeza ndi chrome-zirconium mkuwa, beryllium mkuwa (BeCu) elekitirodi chuma ali apamwamba kuuma (mpaka HRB95~104), mphamvu (mpaka 600 ~ 700Mpa/N/mm²) ndi kufewetsa kutentha (mpaka 650 ° C), koma ake conductivity Kutsika kwambiri komanso kuipiraipira.

Beryllium copper (BeCu) electrode chuma ndi oyenera kuwotcherera mbale mbale ndi kuthamanga kwambiri ndi zipangizo zolimba, monga mawilo kuwotcherera mpukutu kuwotcherera msoko; imagwiritsidwanso ntchito pazinthu zina zama elekitirodi zokhala ndi zofunikira zamphamvu kwambiri monga ndodo zolumikizira ma electrode, Chosinthira ma robot; nthawi yomweyo, ili ndi elasticity yabwino komanso matenthedwe matenthedwe, omwe ndi abwino kwambiri popanga ma chucks opangira mtedza.

Ma electrode a Beryllium copper (BeCu) ndi okwera mtengo, ndipo nthawi zambiri timawalemba ngati zida zapadera za electrode.

3. Copper alumina (CuAl2O3)

Aluminium oxide copper (CuAl2O3) imatchedwanso kubalalitsidwa kumalimbitsa mkuwa. Poyerekeza ndi mkuwa wa chromium-zirconium, uli ndi makina apamwamba kwambiri otenthetsera (kufewetsa kutentha mpaka 900 ° C), mphamvu yayikulu (mpaka 460 ~ 580Mpa/N/mm²), komanso ma conductivity abwino (conductivity 80~85IACS%), zabwino kuvala kukana, moyo wautali.

Aluminiyamu okusayidi mkuwa (CuAl2O3) ndi elekitirodi zinthu ndi ntchito kwambiri, mosasamala kanthu za mphamvu yake ndi kutentha kufewetsa, ali kwambiri madutsidwe magetsi, makamaka kuwotcherera kanasonkhezereka mapepala (electrolytic mapepala), izo sizidzakhala ngati Chromium-zirconium-mkuwa maelekitirodi ndi chodabwitsa cha kumamatira pakati pa elekitirodi ndi workpiece, kotero palibe chifukwa akupera pafupipafupi, amene bwino amathetsa vuto kuwotcherera kanasonkhezereka mapepala, bwino dzuwa, ndi kuchepetsa mtengo kupanga.

Ma elekitirodi a alumina-mkuwa ali ndi ntchito yabwino kwambiri yowotcherera, koma mtengo wawo ndi wokwera mtengo kwambiri, kotero sangathe kugwiritsidwa ntchito kwambiri pakadali pano. Chifukwa cha kuchuluka kwa pepala kanasonkhezereka pakali pano, ntchito yabwino ya zitsulo zotayidwa okusayidi mkuwa kuwotcherera pepala kanasonkhezereka zimapangitsa msika chiyembekezo chake chachikulu. Ma electrode a aluminiyamu amkuwa ndi oyenera kuwotcherera mbali monga malata, zitsulo zopangidwa ndi moto, zitsulo zolimba kwambiri, zinthu za aluminiyamu, mapepala azitsulo za carbon, ndi zitsulo zosapanga dzimbiri.

4. tungsten (W), molybdenum (Mo)

Ma elekitirodi a Tungsten (Tungsten) Ma elekitirodi a Tungsten amaphatikiza ma tungsten oyera, aloyi a tungsten-based high-density alloy ndi tungsten-copper alloy. ) okhala ndi 10-40% (molemera) amkuwa. Molybdenum electrode (Molybdenum)

Ma electrode a Tungsten ndi molybdenum ali ndi mawonekedwe olimba kwambiri, malo oyatsira kwambiri, komanso magwiridwe antchito apamwamba kwambiri. Ndioyenera kuwotcherera zitsulo zosakhala ndi chitsulo monga mkuwa, aluminiyamu, ndi faifi tambala, monga kuwotcherera zingwe zamkuwa ndi ma sheet achitsulo, ndi siliva point brazing.
