Ua rau Slag Inclusion Defects

Thaum lub sij hawm vuam txheej txheem, vuam electrodes thiab steel daim hlau tsim ib co nyiaj ntawm slag, uas tsis tuaj yeem raug tshem tawm tag nrho. Qee qhov ntawm cov slag no tseem nyob rau hauv weld seam, thaum kawg tsim slag inclusion defects nyob rau hauv weld. Slag inclusion defects kuj yog ib qho teeb meem ntau dua hauv cov txheej txheem vuam. Muaj ntau cov qauv kev faib tawm rau slag inclusions, txhua tus elucidating qhov ua los ntawm ntau qhov kev xav. Thaum lub sij hawm vuam, kev siv alkaline vuam electrodes nyiam tsim oxides nyob rau hauv high-temperature. Tshwj xeeb tshaj yog nyob rau hauv kev cuam tshuam ntawm vuam tam sim no, oxides nyob rau hauv vuam electrode thiab oxides nyob rau hauv cov hlau phaj yog sai generated thiab nkag mus rau hauv qhov sib txawv weld nrog lub vuam pas. Thaum lub sij hawm txias txheej txheem ntawm cov hlau, slag inclusion defects yog nquag tsim.
