Thaum lub qhov cub calcium carbide nyob rau hauv ib txwm tsim, sintering ceev thiab noj ceev ntawm cov electrode ncav cuag ib tug dynamic tshuav nyiaj li cas. Kev tshawb fawb thiab rationally tswj kev sib raug zoo ntawm cov electrode siab tso tawm thiab noj yog tsim los tshem tawm ntau yam electrode xwm txheej, txhim kho qhov ua tau zoo ntawm lub cub hluav taws xob, thiab txo ntau yam kev siv. Tus yuam sij rau kev txhim kho kev lag luam.
(1) Ua tib zoo ntsuas cov electrodes txhua hnub, ua tib zoo saib xyuas cov roasting ntawm peb theem electrodes. Raws li ib txwm muaj, qhov qis ntawm lub nplhaib hauv qab yog li 300 hli, lub phaj arc thiab rib phaj ntawm lub tog raj kheej electrode yuav tsum tsis zoo, thiab cov electrode yog greyish dawb los yog tsaus tab sis tsis liab. ; Yog hais tias lub arc phaj thiab rib phaj ntawm lub electrode lub tog raj kheej nyob rau hauv lub electrode hauv qab nplhaib yog kub hnyiab heev, thiab lub electrode yog ci dawb los yog liab, nws txhais tau hais tias lub electrode muaj overheated phenomenon; Yog tias cov pa luam yeeb dub tawm, nws txhais tau tias cov electrode tsis ci txaus thiab cov electrode yog mos. Los ntawm kev soj ntsuam cov xwm txheej saum toj no, lub sijhawm tsim nyog ntawm electrode nias thiab tawm thiab tswj tam sim no tau tsim los tiv thaiv qhov tshwm sim ntawm electrode xwm txheej.
(2) Thaum lub sijhawm ua haujlwm ib txwm muaj, cov khoom siv hluav taws xob tam sim no raug tswj nyob rau hauv qhov ntau ntawm cov txheej txheem yuav tsum ua kom ntseeg tau tias qhov ntev ntawm electrode. Thaum lub tshuab hluav taws xob nyob rau hauv tag nrho cov khoom, qhov ntev ntawm cov electrode tob rau hauv cov khoom txheej feem ntau yog 0.9 mus rau 11 npaug ntawm txoj kab uas hla ntawm electrode. Ua kom tsim nyog tso tawm raws li lub sijhawm ua kom sov; tuav qhov zoo ntawm raw cov ntaub ntawv nkag mus rau hauv lub Hoobkas los ntawm qhov chaw, thiab xyuas kom meej tias tag nrho cov ntsuas ntawm raw khoom nkag mus rau hauv lub cub tawg ua tau raws li cov txheej txheem yuav tsum tau; kev ziab ntawm cov ntaub ntawv carbon yuav tsum tau ua raws li cov txheej txheem, thiab kev tshuaj xyuas cov ntaub ntawv raw yuav tsum tau ua kom cov hmoov nplej.
(3) Electrode nias thiab tso tawm yuav tsum tau nqa tawm tsis tu ncua (tsawg dua li 20 hli los them nyiaj rau kev noj), lub sij hawm luv ntawm electrode nias thiab tawm yuav tsum tsis tu ncua, thiab ntau dhau nias thiab tawm yuav tsum zam kom tsis txhob muaj lub sijhawm luv luv, vim tias qhov no yuav cuam tshuam rau thaj chaw kub thiab muaj peev xwm ua rau muaj teeb meem ntawm electrode, yog tias tsim nyog los ua kom lub siab loj tso tawm, cov electrode tam sim no yuav tsum tau txo, thiab tom qab qhov kub thiab txias tau rov tsim dua, cov electrode tam sim no yuav tsum tau maj mam nce. .
(4) Thaum lub electrode ntawm ib lub sij hawm luv luv, lub sij hawm luv rau kev nias thiab tso tawm cov electrode yuav tsum luv txhua lub sij hawm; qhov tam sim no ntawm electrode ntawm theem no yuav tsum tau nce kom tsim nyog, thiab kev ua haujlwm ntawm electrode ntawm theem no yuav tsum raug txo kom ua tiav lub hom phiaj ntawm kev txo qis kev noj ntawm electrode ntawm theem no; Tus nqi txo tus neeg sawv cev rau lub electrode ntawm theem no; Yog hais tias lub electrode luv dhau lawm, nws yog ib qho tsim nyog yuav tsum tau siv lub tshuab hluav taws xob qis los ua haujlwm ntawm roasting electrode.
(5) Thaum lub electrode ntawm ib theem ntev dhau lawm, lub sijhawm luv ntawm kev nias thiab tso tawm cov electrode ntawm theem no yuav tsum txuas ntxiv; Nyob rau hauv qhov tseeb hais tias qhov tob ntawm lub electrode mus rau hauv lub cub tawg ua tau raws li tus txheej txheem yuav tsum tau, lub electrode yuav tsum tau lifted, lub khiav hauj lwm tam sim no ntawm lub electrode ntawm theem no yuav tsum tau txo, thiab lub khiav hauj lwm tam sim no ntawm lub electrode ntawm theem no yuav tsum tau nce. Kev ua haujlwm thiab kev siv; Raws li cov txheej txheem rau lub cub tawg, tsim nyog txo qhov sib piv ntawm tus neeg sawv cev txo qis rau cov electrode ntawm theem no: nce tus naj npawb ntawm lub sij hawm uas cov electrode ntawm theem no sib raug rau lub qhov hluav taws xob hluav taws xob; nce qhov txias ntawm electrode ntawm theem no.
(6) Muab qhov xaus rau kev nias thiab tso tawm haujlwm tom qab qhov seem sintering tau txav mus los; muab qhov kawg rau nias thiab tso cov electrodes nyob rau hauv cov xwm txheej ntawm qhuav kub los yog qhib arc; tiv thaiv cov khoom tsis txaus los yog nias thiab tso cov electrodes thaum cov ntaub ntawv tab tom yuav tawg; ib tug neeg yuav tsum tuaj rau ntawm qhov chaw los nias thiab tso tawm electrodes Saib seb lub siab thiab qhov tso tawm ntawm peb-theem electrodes yog qhov qub thiab seb qhov paug tawm puas tau raws li qhov yuav tsum tau ua. Yog hais tias qhov paug tawm ntawm cov electrodes tsis txaus los yog cov electrodes plam, qhov ua rau yuav tsum tau nrhiav thiab kho.
