I-Cast iron welding alloy ekwazi ukumelana ne-oxidation-corrosion, i-NiFe-1 Isithombe Esifakiwe

Ingxubevange yensimbi yokushisela i-NiFe-1 engangeni kwi-oxidation-corrosion

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-Cast iron welding rod ivame ukusetshenziselwa ukuxazulula igobolondo lenjini, umzimba wekhava, isisekelo somshini, amazinyo akhiphayo avela ukuphuka kwesondo, ukuqhekeka, ukuguga, izinkinga zokushisela imbobo.Ngenxa yokuqukethwe kwekhabhoni ephezulu, isakhiwo esingalingani, amandla aphansi kanye ne-plasticity empofu, i-cast iron electrode iyinto empofu ye-weldability, okulula ukukhiqiza imifantu ngesikhathi se-welding, kunzima ukuyisika.Ukuze kuzuzwe imiphumela egculisayo ekushiseleni nasekulungiseni ukushisela kwensimbi ekhonjiwe, kubalulekile ukunaka "Izingxenye ezintathu zezinto ezibonakalayo kanye nenqubo yezingxenye eziyisikhombisa", hhayi nje ukukhetha induku yokushisela, kodwa futhi nokuthatha indlela efanelekile yokulungisa i-welding.
Inqubo elandelayo yokufaka i-welding inconywa njengereferensi ye-cast iron welding kanye ne-welding yokulungisa: 1, qala ngokususa izingxenye zokushisela ze-sludge, isihlabathi, amanzi, ukugqwala nezinye izibi;Ngaphezu kwalokho, ungqimba olubi lwe-carbon-poor kanye nongqimba lwe-oxide ebusweni bezinsimbi ezisebenza ngaphansi kwe-High Temperature kanye nemvelo yesitimu isikhathi eside kufanele kususwe.2. Ngokusho kokuma nohlobo lwesici sengxenye eshiselwe, izinyathelo zokulungiselela ezifana nokuvulwa kwe-groove, ukuvimbela ukuvimbela ukubhoboza umgodi kanye nokubunjwa kwe-pool encibilikisiwe kwenziwa.3. Ezingxenyeni ezidinga i-welding ebandayo, zishise kuqala ku-500-600 ° C, khetha i-welding efanelekayo yamanje, eqhubekayo, gcina izinga lokushisa lokushisa ngesikhathi senqubo yokushisela, ukumboza izinto zokuvikela ezifana ne-asbestos powder ngokushesha ngemva kokushisela, futhi uzivumele. ipholile kancane, ukuze ithuthukise ukumelana kwayo nokuqhekeka nokusebenza kokucubungula.4. Ukuze uthole izingcezu zomsebenzi we-welding obandayo, vimbela ukuncibilika kwensimbi eyisisekelo kakhulu, ukunciphisa ukuthambekela komhlophe, ukuvimbela ukushisa okukhulu kakhulu, okuholela ekucindezelekeni ngokweqile, okwamanje okuncane, i-arc emfushane kanye ne-narrow pass welding kufanele isetshenziswe ngangokunokwenzeka ( ubude bephasi ngalinye akumele budlule ku-50mm) .Ngokushesha ngemva kokushisela isando ukushisela ukuze uphumule ukucindezeleka ukuvimbela ukuqhekeka, kuze kube yilapho izinga lokushisa lehla laya ku-60 degrees C ngaphansi kwenye i-weld.5, naka imbobo ye-arc lapho uvala, ukuze uvimbele ukuqhekeka kwe-arc evalayo.
