Hauv kev lag luam kev lag luam thiab kev kho cov khoom siv, covKev Sib Txuas Ncejsawv cev rau ib qho khoom siv tseem ceeb rau kev txuas lub neej ua haujlwm ntawm cov khoom siv tshuab. Tsis zoo li cov pas nrig vuam txheem uas tsim los rau kev sib txuas cov ntaub ntawv, hom electrode no tau tsim tshwj xeeb los tso ib txheej ntawm cov hlau tsis kam lossis xeb rau ntawm qhov chaw hlau. Cov txheej txheem no, hu ua surfacing lossis hardfacing, yog qhov tseem ceeb rau kev tsim kho dua tshiab cov khoom siv thiab tiv thaiv cov khoom tshiab los ntawm kev ua tsis tiav ua ntej.
Lub D256 (B-80) yog ib qho piv txwv zoo ntawm cov khoom siv tshwj xeeb Surfacing Welding Rod. Nws yog ib lub electrode yooj yim uas tsim los tso cov hlau austenitic manganese steel weld. Cov hlau no yog lub npe nrov rau nws qhov kev sib xyaw ua ke ntawm kev tawv siab thiab kev ua haujlwm zoo heev. Thaum pib, cov hlau uas tso rau hauv lub raj mis yog mos thiab ductile, tab sis nws tawv sai sai thaum txias deformation, uas tshwm sim hauv qab kev cuam tshuam lossis kev nyuaj siab, ua rau nws tiv taus kev hnav ntxiv.
Qhov kev thov tseem ceeb rau qhov noKev Sib Txuas Ncejyog nyob rau hauv kev rov ua dua thiab kev tiv thaiv ntawm cov khoom uas raug kev cuam tshuam loj heev nrog rau qib nruab nrab ntawm kev puas tsuaj. Nws yog qhov zoo tagnrho rau kev vuam rau ntawm cov khoom ua los ntawm cov hlau austenitic manganese zoo sib xws, cov khoom siv feem ntau siv hauv kev lag luam siab. Cov khoom ib txwm kho nrog tus pas nrig no suav nrog kev hla txoj kev tsheb ciav hlau, lub puab tsaig crusher, thiab cov hniav shovel hauv cov khoom siv mining thiab kev tsim kho.
Kev siv cov Surfacing Welding Rod no kom raug yuav tsum ua raws li cov txheej txheem vuam tshwj xeeb kom ua tiav cov txiaj ntsig zoo tshaj plaws. Vim nws cov txheej txheem yooj yim, nws feem ntau ua haujlwm ntawm lub zog hluav taws xob ncaj qha (DC) nrog lub electrode txuas nrog lub ncej zoo (DCEP). Kev ua kom cov hlau hauv paus ua ntej feem ntau tsis pom zoo rau cov hlau manganese, thiab kev tswj qhov kub ntawm qhov sib tshuam yog qhov tseem ceeb kom tiv thaiv kev nkag mus rau hauv cua sov ntau dhau, uas tuaj yeem ua rau cov hlau tso thiab cov khoom hauv paus tsis ruaj khov.
Kev siv txoj kev tshwj xeeb ntawm kev lag luamKev Sib Txuas Ncejzoo li D256 (B-80) yog ib qho kev coj ua tseem ceeb hauv kev tswj hwm cov khoom lag luam. Los ntawm kev xaiv cov electrode tsim nyog rau hom kev hnav tshwj xeeb—hauv qhov no, muaj kev cuam tshuam loj heev—Cov pab pawg kho tuaj yeem tsim kho cov khoom tseem ceeb dua, txo lub sijhawm tsis ua haujlwm, thiab txo cov nqi ua haujlwm mus sij hawm ntev. Cov Surfacing Welding Rod no muab kev daws teeb meem txhim khu kev qha thiab ua haujlwm tau zoo rau kev txhim kho lub zog ntawm cov tshuab ua haujlwm nyob rau hauv cov xwm txheej nyuaj tshaj plaws.
