oxidation-zimbiri zosagwira Cast iron welding alloy NiFe-1

Ndodo yowotcherera chitsulo nthawi zambiri imagwiritsidwa ntchito pothetsa chipolopolo cha injini, chivundikiro cha thupi, makina oyambira, mano oponyera amawonekera kusweka kwa magudumu, ming'alu, kuvala, zovuta zowotcherera dzenje.Chifukwa chokhala ndi mpweya wambiri, mawonekedwe osagwirizana, mphamvu zochepa komanso pulasitiki yosauka, ma elekitirodi achitsulo ndi chinthu chochepa kwambiri chowotcherera, chomwe chimakhala chosavuta kupanga ming'alu panthawi yowotcherera, n'zovuta kudula.Kuti tikwaniritse zotsatira zokhutiritsa pakuwotcherera ndi kukonza kuwotcherera kwachitsulo, ndikofunikira kulabadira "Zigawo zitatu zakuthupi ndi magawo asanu ndi awiri", osati kungosankha ndodo yowotcherera, komanso kutengera njira yoyenera yowotcherera.
Zotsatirazi kuwotcherera ndondomeko tikulimbikitsidwa monga Buku kuponyedwa chitsulo kuwotcherera ndi kukonza kuwotcherera: 1, choyamba kuchotsa kuwotcherera mbali sludge, mchenga, madzi, dzimbiri ndi zinyalala zina;Komanso, wosanjikiza mpweya osauka ndi okusayidi wosanjikiza pamwamba zitsulo castings ntchito pansi High Kutentha ndi nthunzi chilengedwe kwa nthawi yaitali ayenera kuchotsedwa.2. Malingana ndi mawonekedwe ndi mtundu wa chilema cha gawo losungunuka, njira zokonzekera monga kutsegulira kwa groove, kutsekereza kutsekeka kwa dzenje ndi kusungunula kwa dziwe kumachitika.3. Pazigawo zomwe zimafunikira kuwotcherera kozizira, zitenthetseni pa 500-600 ° C, sankhani kuwotcherera koyenera, kosalekeza, sungani kutentha kwa preheating panthawi yowotcherera, kuphimba zida zotchingira monga ufa wa asbestosi mukangowotcherera, ndikuwasiya. kuziziritsa pang'onopang'ono, kuti apititse patsogolo kukana kwake kwa mng'alu ndi kukonza magwiridwe antchito.4. Pazidutswa zozizira zowotcherera, pewani chitsulo chosungunula kwambiri, kuchepetsa chizolowezi choyera, kupewa kutentha kwambiri, zomwe zimapangitsa kuti mukhale ndi nkhawa kwambiri, pakali pano, arc yaying'ono ndi yopapatiza yowotcherera iyenera kugwiritsidwa ntchito momwe mungathere. kutalika kwa chiphaso chilichonse sayenera kupitirira 50mm).Mutangotha ​​kuwotcherera nyundo weld kuti muchepetse nkhawa kuti mupewe kusweka, mpaka kutentha kumatsika mpaka 60 ° C pansi pa weld wina.5, tcherani khutu ku dzenje la arc potseka, kuti mupewe kutsekeka kwa arc.
