1. Xaiv cov graphite rods nrog cov cua sov zoo sib xws hauv thaj chaw cua sov. Qhov tsis zoo ntawm cov cua sov yuav cuam tshuam rau qhov kub thiab txias tsis sib xws thiab ua rau tus pas nrig lub neej luv. Thaum siv, qhov sib xws ntawm cov cua sov yuav maj mam deteriorate, uas yuav ua rau cov pas nrig tawg nyob rau hauv cov xwm txheej hnyav.
2. Lub neej ntev ntawm graphite rods txo nrog kev ua haujlwm kub, tshwj xeeb tshaj yog thaum qhov kub thiab txias tshaj 1500 degree, raws li oxidation tus nqi nrawm thiab lub neej luv. Thaum siv, sim kom tsis txhob muaj qhov kub thiab txias ntawm cov graphite rods.
3. Thaum cua sov hauv huab cua, cov ntaub ntawv tuab silicon oxide ua rau ntawm qhov chaw ntawm graphite pas nrig, ua raws li cov txheej txheem tiv thaiv oxidation thiab ua kom nws lub neej ntev. Kev siv tsis tu ncua, nrog kev hloov pauv hauv qhov kub thiab txias, tuaj yeem ua rau cov yeeb yaj kiab tiv thaiv ntawm tus pas nrig nto tawg, ua rau cov nyhuv tiv thaiv tsis muaj zog thiab ua kom lub zog nce ntawm tus pas nrig.
Txhawm rau kom ruaj khov rauv kub thiab ua tau raws li cov kev xav tau ntawm cov cua kub ceev, kev txhawb nqa hluav taws xob tswj yuav tsum muaj qhov hloov pauv qhov hluav taws xob txaus - uas yog, nrog cov pas nrig tshiab, lub tshuab hluav taws xob tsim thiab lub zog ua haujlwm tuaj yeem ntsib ntawm qhov qis dua; Raws li lub sij hawm siv nce, tus pas nrig kuj nce, yuav tsum muaj kev sib txuas ntxiv hauv qhov hluav taws xob kom tau raws li lub tshuab hluav taws xob tsim thiab lub zog ua haujlwm.
Voltage margin nqi: Qhov voltage nyob rau tom qab theem ntawm graphite pas nrig siv feem ntau yog 1.5-1.7 npaug ntawm qhov voltage siv nrog cov pas nrig tshiab. Nyob ntawm txoj kev tswj hwm qhov hluav taws xob thiab txoj kev xaim, qhov txwv sab saud ntawm cov theem tom qab voltage feem ntau suav tias yog 220V lossis 380V.
Rau kev kho lub zog ntawm graphite rods, nws raug nquahu kom kho lub zog los ntawm kev kho qhov voltage. Thyristor voltage regulation lossis transformer voltage regulation yog pom zoo rau graphite pas nrig voltage hloov. Kho lub zog los ntawm kev hloov cov zaus feem ntau tsis pom zoo.
4. Feem ntau, qhov ntom ntom ntom ntom ntawm cov graphite pas nrig yog txiav txim siab los ntawm kev sib raug zoo ntawm qhov cub kub thiab qhov kub ntawm graphite pas nrig. Nws raug nquahu kom siv tus nqi hluav taws xob ntawm 1/2 txog 1/3 ntawm qhov siab tshaj plaws ntawm qhov ntom ntom ntawm graphite pas nrig. Qhov ntau dua qhov tam sim no siv rau graphite pas nrig, qhov kub ntawm qhov graphite pas nrig yog siab dua. Nws raug nquahu kom siv qhov tsawg tshaj plaws ntawm qhov chaw thau khoom ntom ntom (lub zog).
Thov nco ntsoov tias qhov tseem ceeb tau sau tseg rau ntawm qhov kawg ntawm lub graphite pas nrig yog qhov ntsuas tam sim no thiab qhov hluav taws xob ntsuas hauv huab cua ntawm 1050℃± 50 degree, thiab tej zaum yuav tsis cuam tshuam rau kev siv tiag tiag.
5. Thaum siv cov graphite rods tsis tu ncua, nws raug nquahu kom nce qhov hluav taws xob maj mam ua kom lub neej ntev dua.
6. Graphite rods yuav tsum tau txuas rau tib lub sijhawm thaum ua tau. Yog hais tias qhov kev tiv thaiv qhov tseem ceeb ntawm cov graphite rods txawv, txuas lawv nyob rau hauv series yuav mloog zoo rau lub load ntawm tus pas nrig nrog lub siab tshaj plaws tsis kam, ua rau ib tug ceev ceev nyob rau hauv tsis kam thiab ib tug luv luv lifespan rau tus pas nrig.
Yog li ntawd, nws yog ib qho tsim nyog los ntxiv dag zog rau qhov sib txuam ntawm qhov tseem ceeb ntawm kev tiv thaiv, kom ntseeg tau tias qhov tseem ceeb ntawm cov rods nyob rau hauv tib pawg yog ze li sai tau. Feem ntau, qhov kev tiv thaiv tus nqi sib txawv ntawm cov pas nrig hauv tib pab pawg yuav tsum tsis pub dhau 10% -15% rau kev sib txuas, thiab tsis pub dhau 5% -10% rau kev sib txuas. Qhov kub ntawm lub cub tawg ntau dua, qhov me dua qhov yuav tsum tau muaj qhov sib txawv ntawm qhov yuav tsum tau ua.
