Kev daws rau Slag Inclusion Defects

Txhawm rau txhim kho qhov vuam zoo ntawm cov kav hlau kav thiab ua kom zoo rau cov slag suav nrog qhov tsis xws luag, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas qhov ntev ntawm bevel. Kev txiav txim siab qhov ntev ntawm bevel raws li kev ua tau zoo tuaj yeem tiv thaiv qhov tshwm sim ntawm slag suav nrog qhov tsis xws luag. Tsis tas li ntawd, kev saib xyuas yuav tsum tau them nyiaj rau kev kho cov vuam tam sim no thiab tswj cov vuam ceev, uas ua kom cov cua sov tsis sib xws ntawm cov phaj steel thiab yog li tsis txhob oxide residue nyob rau hauv qhov txias txias lossis kub kub. Ua tib zoo mloog yuav tsum tau muab rau lub viav vias txoj hauj lwm ntawm vuam electrode kom ntseeg tau tias nws txoj kev sib txawv tsis txawv txav, uas tuaj yeem cuam tshuam qhov vuam zoo. Cov vuam slag ntau dhau kuj tuaj yeem ua rau cov slag suav nrog, yog li nws yog ib qho tseem ceeb kom sai li sai tau ntxuav cov vuam slag thaum lub sijhawm ua haujlwm vuam. Qhov zoo ntawm vuam electrode nws tus kheej kuj tseem muaj feem cuam tshuam rau slag suav nrog qhov tsis xws luag. Yog tias siv eccentric electrodes los yog cov khoom siv vuam tsis sib xws, cov slag suav nrog ntau yuav raug tsim tawm. Yog li ntawd, thaum lub sij hawm xaiv cov txheej txheem ntawm vuam electrodes, irregularly zoo li tus electrodes los yog cov uas tsis raug positioned cores yuav tsum tau muab cais tawm, uas yuav zoo tiv thaiv qhov tshwm sim ntawm slag inclusion defects.
