Vuam flux-cored hlau yog hlau sheath, uas yog ua los ntawm steel daim kab xev nrog ib tug tuab ntawm 0.2 mus rau 0.5 millimeters. Lub plhaub tau ntim nrog cov slag thiab cov khoom siv roj.
Flux cored hlau yog siv los tiv thaiv cov roj cua lossis rau kev siv tshuab arc vuam nrog qhib arc. Tuav cov txuj ci zoo ntawm cov qauv hlau, nws tsim slag thiab roj tiv thaiv los ntawm huab cua atmospheric. Qhov no tseem ceeb tshwj xeeb tshaj yog thaum ua haujlwm hauv thaj chaw qhib. Cored hlau muab refining thiab alloying ntawm seam. Thaum siv nws, nws raug tso cai siv tam sim no muaj qhov ceev ntawm 150-170 A / mm2. Rau phau ntawv arc vuam nrog qhib electrodes, tam sim no muaj qhov ceev ntawm tsis ntau tshaj 20 A / mm2. Cored hlau, yog li, tso cai rau kom ua tau zoo ntawm cov txheej txheem los ntawm ib thiab ib nrab mus rau ob zaug.
Muaj ntau hom khoom siv hluav taws xob txuas ntxiv. Yog li, piv txwv li, rau vuam txias ntawm cam khwb cia hlau, cov khoom siv qib PP-Ch1 yog siv, rau vuam kub - PP-Ch3.
Nws yuav tsum raug sau tseg tias cov txheej txheem thev naus laus zis ntawm kev koom nrog hlau siv electrodes yog ib txoj hauv kev tseem ceebdaws ntau yam teeb meem ntawm kev tshawb fawb thiab thev naus laus zis. Cov txheej txheem no yog siv nyob rau hauv yuav luag txhua qhov chaw ntawm lub teb chaws kev lag luam. Cored hlau yog suav hais tias yog cov khoom lag luam zoo heev. Nws siv tsis tau tsuas yog kev tsim khoom, tab sis kuj ua haujlwm zoo.
Nws yog siv los nthuav ntau yam ntawm cov khoom tso cia. Nws siv yog tsim nyog tshwj xeeb tshaj yog nyob rau hauv cov rooj plaub thaum alloyed monolithic hlau rau tej yam hlau tsis tau los ntawm ib tug metallurgical txoj kev.
Cored hlau yog cais raws li txoj kev tiv thaiv siv, lub hom phiaj tseem ceeb, hom tub ntxhais, cov khoom siv kho tshuab, thiab muaj peev xwm vuam hauv ntau txoj haujlwm.
Feem ntau ntawm cov khoom siv niaj hnub no yog siv rau vuam tsis tshua muaj hlau thiab cov hlau tsis tshua muaj carbon. Cored hlau yog tsim rau tshwj xeeb thiab dav siv. Thawj qeb suav nrog cov khoom siv hauv kev ua haujlwm nrog kev tsim cov seam.
Qhov tseem ceeb tshwj xeeb yog kev faib cov khoom raws li cov khoom ntawm cov seam thiab vuam sib txuas. Qhov ntsuas no tso cai rau koj los txiav txim siab qhov tsim nyog ntawm cov khoom ntawm ib lub npe tshwj xeeb rau vuam ntawm ib qho kev tsim, yog tias qhov tsawg kawg nkaus yuav tsum muaj rau cov khoom siv ntawm cov khoom siv tau raug txiav txim siab rau nws. Kev pov thawj ntawm kev ua raws li qhov yuav tsum tau ua yog ua los ntawm kev txheeb xyuas qhov tsawg kawg nkaus yuav tsum tau ntsuas ntawm kev tiv thaiv ib ntus rau kev tawg, nrog rau kev cuam tshuam lub zog ntawm cov hlau suture. Kev ntsuam xyuas yog muab thaum kuaj cov qauv qauv. Txhawm rau txiav txim siab hom xaim raws li qhov lav tau ib ntus tiv thaiv kev tawg, lub zog tensile tau teeb tsa. Thaum faib cov flux-cored hlau, nws yog kev cai los qhia hom khoom, lub zog ntawm cov khoom siv thiab cov haujlwm tso cai (spatial) ntawm vuam.
