Lub B-85 Hardfacing Welding Electrode yog ib qho tshwj xeebHardfacing Rodtsim los tso cov nplaim uas tsis yooj yim hnav rau ntawm cov khoom uas raug kev puas tsuaj loj heev, kev sib txhuam, thiab kev cuam tshuam nruab nrab. Muaj cov txheej txheem flux siab-chromium, cov pas nrig arc no tsim cov overlays tiv thaiv uas tswj kev ncaj ncees hauv qhov kub thiab txias thiab corrosive ib puag ncig. Zoo tagnrho rau kev tsim kho dua tshiab thiab tiv thaiv cov khoom siv hauv kev lag luam, cov pas nrig Hardfacing no txuas ntxiv lub neej kev pabcuam hauv cov xwm txheej ua haujlwm nyuaj.
Lub electrode'Qhov tshwj xeeb ntawm cov chromium flux formulation ua rau cov hlau uas tau tso rau hauv lub cev muaj cov qauv ntom ntom thiab tawv. Cov yam ntxwv ntawm cov hlau no muab kev tiv thaiv zoo rau kev sib tsoo, kev sib tsoo, thiab kev hnav los ntawm cov zaub mov, cov hlau, thiab cov khoom siv abrasive slurries. Lub overlay zoo tiv thaiv cov ntaub ntawv tseem ceeb los ntawm kev puas tsuaj, txawm tias thaum raug rau qhov kub txog li 600°C (1112°F) lossis cov huab cua corrosive uas feem ntau pom muaj nyob rau hauv kev khawb av, cement, thiab cov ntawv thov tuav cov khoom siv.
Qhov tseem ceeb rau nws txoj kev ua tau zoo yog cov khoom siv kho tshuab zoo tshaj plaws uas B-85 xa tuaj.Hardfacing RodThaum siv ob txheej raws li pom zoo, qhov weld deposit ua tiav qhov nyuaj ntawm 57–62 HRc (Rockwell C scale). Qhov tawv ntawm qhov chaw no ncaj qha tawm tsam cov khoom poob los ntawm kev sib txhuam thiab kev sib tsoo siab, txawm hais tias cov nyiaj tso cia yuav tsum tsis txhob raug kev cuam tshuam loj heev lossis kev ntaus hnyav vim nws qhov brittleness ntawm qib tawv no.
Tus pas nrig no zoo heev rau cov khoom siv ntawm qhov chaw xws li lub rauj tsoo, lub augers, cov hniav trencher, cov menyuam pulverizer, thiab cov ntaub thaiv chute. Nws qhov kev ruaj khov kub siab ua rau nws tsim nyog rau cov khoom siv hauv qhov cub thiab cov khoom siv hauv qhov cub. Cov neeg siv yuav tsum nco ntsoov nws cov kev txwv kev ua haujlwm: thaum tiv taus kev sib txhuam thiab kev nias nruab nrab, lub overlay tsis muaj qhov tawv rau cov ntawv thov uas muaj kev rauj hnyav, kev cuam tshuam hnyav, lossis kev ntxhov siab hnyav. Kev ua ntej cua sov thiab tswj qhov kub thiab txias yog qhov tseem ceeb kom tiv thaiv kev tawg.
Rau cov lag luam uas tab tom ntsib teeb meem hnav cov khoom siv kim heev, B-85Hardfacing Rodmuab kev daws teeb meem tiv thaiv uas pheej yig. Nws ua ke ntawm qhov nyuaj heev (57–62 HRc), kev ruaj khov kub / corrosion, thiab chromium-enhanced abrasion resistance ua rau qhov Hardfacing Rod no tsis tseem ceeb rau kev tsim kho dua tshiab cov tshuab tseem ceeb. Siv kom raug hauv nws cov kev txwv kev cuam tshuam, nws txo qis lub sijhawm tsis ua haujlwm thiab cov nqi hloov pauv thoob plaws kev tsuas, hlau, thiab cov khoom siv ua haujlwm hnyav.
