Graphite electrodes yog siv feem ntau hauv Electric Arc Rauv lossis Ladle Furnace steel manufacturing.
Graphite electrodes tuaj yeem muab cov khoom siv hluav taws xob siab thiab muaj peev xwm txhawb nqa cov qib siab ntawm cov hluav taws xob tsim hluav taws xob. Graphite electrodes kuj tseem siv rau hauv kev kho cov hlau thiab cov txheej txheem smelting zoo sib xws.
1. Tus tuav electrode yuav tsum tau tuav nyob rau hauv qhov chaw dhau ntawm txoj kab kev ruaj ntseg ntawm sab saum toj electrode; txwv tsis pub cov electrode yuav yooj yim tawg. Qhov chaw sib cuag ntawm tus tuav thiab electrode yuav tsum tau muab ntxuav kom tsis tu ncua kom muaj kev sib cuag zoo. Lub tsho txias ntawm tus tuav yuav tsum zam kom tsis txhob muaj dej tawm.
2. Txheeb xyuas cov laj thawj yog tias muaj qhov sib txawv ntawm cov electrode hlws ris, tsis txhob siv qhov sib txawv ntawm qhov sib txawv.
3. Yog hais tias muaj qhov poob ntawm lub txiv mis ntsia liaj qhov rooj thaum txuas electrodes, nws yog ib qho tsim nyog los ua kom tiav lub txiv mis bolt.
4. Daim ntawv thov ntawm electrode yuav tsum tsis txhob tilting lub lag luam, tshwj xeeb tshaj yog, cov pab pawg neeg ntawm kev cob cog rua electrodes yuav tsum tsis txhob muab horizontally thiaj li tiv thaiv kom txhob tawg.
5. Thaum them cov ntaub ntawv rau lub cub tawg, cov ntaub ntawv loj yuav tsum tau them rau qhov chaw ntawm lub cub tawg hauv qab, thiaj li txo qhov cuam tshuam ntawm cov khoom siv hluav taws xob loj ntawm lub cub tawg.
6. Cov khoom loj ntawm cov ntaub ntawv rwb thaiv tsev yuav tsum tsis txhob muab tso rau hauv qab ntawm cov electrodes thaum smelting, thiaj li tiv thaiv kom tsis txhob cuam tshuam cov electrode siv, los yog txawm tawg.
7. Tsis txhob tsoo lub hau ntawm lub cub tawg thaum nce lossis tso cov electrodes, uas yuav ua rau cov electrode puas.
8. Nws yog ib qho tsim nyog los tiv thaiv cov hlau slag los ntawm txaws mus rau cov xov ntawm cov electrodes los yog lub txiv mis khaws cia rau hauv qhov chaw smelting, uas kuv puas qhov precision ntawm threads.
► Qhov Ua rau Electrode Breakage
1. Electrode kev ntxhov siab los ntawm downward quab yuam ntawm qhov kev txiav txim ntawm kev txo qis; qhov sib koom ua ke ntawm electrodes thiab txiv mis nyob rau hauv clamping ntaus ntawv siv lub zog siab tshaj plaws.
2. Thaum electrodes tau txais sab nraud quab yuam; Kev ntxhov siab ntawm sab nraud quab yuam ntau dua li cov electrode tuaj yeem tiv taus ces lub zog yuav ua rau electrode tawg.
3. Qhov ua rau sab nraud quab yuam yog: melting ntawm bulk charge vau; cov khoom tsis-conductive hauv qab cov electrode: cuam tshuam ntawm cov hlau loj loj ntws thiab lwm yam. Clamping device lifting teb ceev uncoordinated: ib feem ntawm lub qhov taub hau electrode; electrodes gap txuas nrog kev sib txuas tsis zoo thiab lub txiv mis lub zog tsis tuaj yeem ua raws.
4. Electrodes thiab txiv mis nrog tsis zoo machining raug.
► Kev ceev faj rau kev siv graphite electrode:
1. Cov graphite electrodes ntub dej yuav tsum tau qhuav ua ntej siv.
2. Cov kaus mom tiv thaiv npog ntawm lub qhov (socket) electrodes yuav tsum raug muab tshem tawm kom paub tseeb qhov tseeb ntawm cov xov hauv ntawm lub qhov (socket) electrode.
3. Qhov chaw ntawm cov electrodes thiab cov xov sab hauv ntawm lub qhov (socket) yuav tsum tau tshem tawm los ntawm huab cua compressed tsis muaj roj thiab dej. Tsis muaj steel wool lossis hlau xuab zeb daim ntaub yuav tsum tau siv nyob rau hauv xws li clearance.
4. Lub txiv mis yuav tsum tau ua tib zoo screwed rau hauv lub qhov (socket) electrode ntawm ib kawg ntawm lub electrode yam tsis muaj kev sib tsoo nrog cov xov sab hauv t yog tsis pom zoo kom ncaj qha tso lub txiv mis rau hauv electrode tshem tawm ntawm lub cub tawg)
5. Cov khoom nqa nqa (nws yog qhov zoo dua los siv graphite lifting appliance) yuav tsum tau ntsia hlau rau hauv lub qhov (socket) electrode ntawm lwm qhov kawg ntawm cov electrode.
6. Thaum nqa cov electrode, cov ntaub ntawv zoo li cushion yuav tsum muab tso rau hauv av hauv qab qhov kawg ntawm cov electrode kom tsis txhob muaj kev sib tsoo. Tom qab lub lifting hock tau muab tso rau hauv lub nplhaib ntawm lub lifting apparatus. Lub electrode yuav tsum tau nqa kom du kom tsis txhob ntog lossis sib tsoo nrog lwm yam khoom siv.
7. Lub tshuab hluav taws xob yuav tsum tau nqa saum lub taub hau ntawm lub tshuab hluav taws xob ua haujlwm thiab poob maj mam tsom rau ntawm lub qhov hluav taws xob electrode. Tom qab ntawd cov electrode yuav tsum tau screwed kom lub helical nuv thiab lub electrode poob thiab tuning ua ke. Thaum qhov kev ncua deb ntawm lub ntsej muag kawg ntawm ob lub electrodes yog 10-20mm, ob lub ntsej muag kawg ntawm cov electrodes thiab sab nraud ntawm lub txiv mis yuav tsum tau muab tshem tawm dua los ntawm huab cua compressed. Thaum kawg lub electrode yuav tsum tau muab tso rau hauv maj mam, los yog cov xov ntawm lub qhov (socket) electrode thiab lub txiv mis yuav puas vim yog kev sib tsoo hnyav.
8. Siv torque spanner los ntsia hlau electrode kom txog thaum kawg ntawm ob lub electrodes tiv tauj ze (qhov sib txawv ntawm qhov sib txuas ntawm cov electrodes yog tsawg dua 0.05mm).
Yog xav paub ntxiv txog kev siv cov graphite electrodes, ua siab zoo tswj xyuas peb txhua lub sijhawm.
