1. Qhov zoo ntawm cov electrode paste
Cov kev xav tau zoo ntawm cov electrode paste yog kev ua tau zoo roasting, tsis muaj kev tawg mos thiab tawg nyuaj, thiab kev ua tau zoo thermal conductivity; lub electrode ci yuav tsum muaj lub zog txaus, zoo heev thermal shock tsis kam, hluav taws xob poob siab tsis kam, porosity tsawg, tsis tshua muaj resistivity thiab zoo oxidation tsis kam.
Cov electrodes ci nws tus kheej no muaj kev siv hluav taws xob tsawg nyob rau hauv tib lub qhov cub calcium carbide.
2. Cov khoom siv raw thiab cov khoom zoo siv hauv lub cub hluav taws xob
Qhov me dua qhov me me ntawm cov khoom siv carbon, qhov ntau dua qhov tsis kam, qhov tob dua qhov electrode raug ntxig rau hauv qhov them, qhov siab dua qhov kub ntawm lub cub tawg, qhov sai dua qhov kev ua haujlwm, thiab qhov zoo dua qhov kev tsim khoom. Qhov qeeb qeeb ntawm electrode raug oxidized, qhov qeeb qeeb ntawm electrode paste raug noj; qhov siab dua cov pa roj carbon ntawm cov khoom siv carbon, qhov siab dua qhov nqi piv Siab dua, qhov tsawg dua electrode carbon koom nrog hauv qhov kev ua haujlwm, qhov qeeb qeeb ntawm electrode paste noj; qhov siab dua cov calcium oxide ua haujlwm ntawm cov txiv qaub ntsuab, qhov qeeb qeeb ntawm electrode noj. Sai dua; qhov loj dua qhov loj me ntawm cov txiv qaub ntsuab, qhov qeeb qeeb ntawm electrode noj; qhov siab dua cov pa roj ntawm calcium carbide, qhov qeeb qeeb ntawm electrode noj.
3. Kev kho cov txheej txheem xws li tam sim no thiab voltage Tsawg voltage, kev ua haujlwm tam sim no siab, qeeb noj electrode paste; me me zog ntawm electrodes, qeeb noj electrode paste.
4. Qib kev tswj hwm kev ua haujlwm ntawm electrode Thaum cov kua qaub ntxiv feem ntau thaum lub sijhawm ua haujlwm, kev siv cov electrode paste yuav raug nrawm dua; kev tawg nyuaj thiab kev tawg mos ntawm electrodes yuav ua rau kev siv cov electrode paste ntau ntxiv; qhov siab ntawm cov electrode paste yuav cuam tshuam rau kev siv cov electrode paste. Yog tias qhov siab ntawm cov electrode paste qis dhau, qhov ceev sintered ntawm electrode yuav txo qis, uas yuav ua rau kev siv cov electrode paste sai dua; kev hlawv qhuav ntawm qhov qhib arc yuav ua rau kev siv cov electrode paste ntau ntxiv; yog tias cov electrode paste tsis raug tswj hwm kom zoo, hmoov av yuav poob rau ntawm cov electrode paste, ua rau muaj kev nce ntawm tshauv kuj tseem yuav ua rau kev siv cov electrodes ntau ntxiv.
Lub electrode ntev npaum li cas, qhov kev siv qeeb dua, thiab lub electrode luv npaum li cas, qhov kev siv sai dua. Lub electrode ntev npaum li cas, qhov degree graphitization ntawm lub electrode zoo dua nyob rau hauv thaj chaw kub ntawm lub them, qhov zoo dua lub zog, thiab qhov kev siv qeeb dua; ntawm qhov tsis sib xws, lub electrode luv npaum li cas, qhov kev siv sai dua. Kev khaws qhov ntev ntawm qhov kawg ua haujlwm ntawm lub electrode yuav ua rau kev siv lub electrode nkag mus rau hauv lub voj voog zoo. Qhov kawg ua haujlwm luv ntawm lub electrode yuav rhuav tshem lub voj voog zoo no. Yog tias nws raug txav mus, nws yooj yim ua rau lub electrode slippage, core rub, paste to, mos tawg thiab lwm yam xwm txheej. Kev xyaum ua haujlwm ua pov thawj tias qhov cuam tshuam ntawm kev tsim khoom phem dua, qhov thauj khoom tsawg thiab cov zis tsawg, qhov kev siv electrode paste ntau dua; qhov cuam tshuam ntawm kev tsim khoom zoo dua, qhov kev siv electrode paste tsawg dua. Yog li ntawd, kev txhim kho qib kev txawj ntse ntawm cov neeg ua haujlwm calcium carbide thiab kev tswj hwm kev siv electrode paste yog qhov ntsuas tseem ceeb los txo qhov xwm txheej electrode thiab kev siv electrode paste, thiab nws kuj yog ib qho kev txawj yooj yim uas cov neeg ua haujlwm calcium carbide yuav tsum paub txog hauv lawv txoj haujlwm.
