Graphite electrode yog ib qho tseem ceeb ntawm high-temperature conductive khoom rau hluav taws xob rauv steelmaking. Lub zog hluav taws xob yog nkag mus rau hauv lub cub hluav taws xob los ntawm cov graphite electrode, thiab qhov kub thiab txias tsim los ntawm lub arc nruab nrab ntawm cov electrode kawg thiab tus nqi yog siv los ua cov cua kub los yaj cov nqi rau steelmaking. Specifications muaj li ntawm 300 mus rau 800mm inch thiab 1.8m, 2.1m, 2.4m, thiab 2.7m nyob rau hauv ntev.

Cov txheej txheem tsim khoom yog calcine petroleum coke ntawm 1350 ° C. Lub resulting calcined coke yog crushed, av thiab tshuaj ntsuam los tsim cov aggregate thiab hmoov yuav tsum tau rau molding. Cov koob coke thiab hmoov yog ua tiav siv cov mis tshwj xeeb rau molding. Cov calcined coke yog tov nrog ntau qhov ntau thiab tsawg, sib txawv proportions thiab ib qho kev faib ua feem ntawm binder asphalt nyob rau hauv lub kneader raws li ib tug tej yam kub thiab lub sij hawm.

Tom qab kneading, cov pa roj carbon paste raug xa mus rau cov khoom chamber ntawm molding xovxwm los ntawm txoj siv conveyor, thiab yog siv los ntawm cov khoom siv molding. Yas deformation tshwm sim nyob rau hauv sab nraud quab yuam, nws thiaj li tsim ib tug electrode ntsuab lub cev (los yog ntsuab khoom) nrog ib tug tej yam zoo li, loj, ceev thiab lub zog. Cov khoom ntsuab yog muab tso rau hauv lub cub tawg tshwj xeeb uas tsim los rau kev kho cua sov kub ntawm 1300 ° C kom carbonize thee pitch nyob rau hauv ntsuab lub cev los tsim cov khoom uas muaj zog dua txhua yam, qis resistivity, zoo thermal stability thiab tshuaj stability.

Rau cov khoom siv carbon, roasting yog ib qho ntawm cov txheej txheem tseem ceeb hauv kev tsim cov khoom carbon. Lub voj voog roasting ntau lawm ntev (22-30 hnub rau thawj roasting, 5-20 hnub rau qhov thib ob roasting nyob ntawm hom rauv), thiab lub zog noj yog siab. Tom qab ntawd, cov khoom siv carbon tau muab tso rau hauv lub nkoj siab, thiab cov kua impregnating tus neeg sawv cev asphalt yog immersed thiab nkag mus rau hauv cov electrode pores ntawm cov khoom nyob rau hauv cov xwm txheej ntawm 360-400 ° C thiab 1.5-1.8MPa siab kom nce ntim ceev. thiab mechanical zog ntawm cov khoom, thiab txhim kho cov conductivity thiab conductivity ntawm cov khoom. Thermal conductivity.

Tom qab cov khoom roasted yog impregnated, nws yog roasted dua rau carbonize lub suab rau hauv lub pores ntawm cov khoom ci. Tom qab ntawd ntxiv ib qho kev tiv thaiv nruab nrab rau cov khoom ci ci hauv qhov cub hluav taws kub kub kom sov cov khoom siv roj carbon monoxide kom siab tshaj 2800 ° C, hloov cov amorphous turbostratic carbon rau hauv peb-dimensional graphite siv lead ua qauv los txhim kho cov hluav taws xob conductivity, thermal conductivity, thiab kub tsis kam ntawm cov khoom siv carbon. Kev vibration kev ua tau zoo thiab tshuaj lom neeg ruaj khov ua rau cov khoom siv roj carbon lubrication thiab tiv thaiv hnav, thiab tso tawm impurities los txhim kho cov purity ntawm cov khoom carbon. Thaum kawg, peb cia siab rau kev txiav ua kom tiav qhov yuav tsum tau muaj qhov loj me, cov duab, precision, thiab lwm yam, thiab ua rau lub cev electrode uas ua tau raws li qhov yuav tsum tau siv.
Vim tias cov pob qij txha electrode yuav tsum muaj lub cev hnyav thiab tsis muaj zog, cov txheej txheem ua haujlwm yuav tsum muaj peb lub dips thiab plaub firings kom tau raws li qhov yuav tsum tau ua.
Peb lub tuam txhab cov khoom ua raws li YB / T4088-2015, YB / T4089-2015, YB / T4090-2015 cov qauv. Cov graphite electrodes thiab cov pob qij txha tsim muaj qhov ntim siab, siab flexural zog, tsis tshua muaj zog, zoo thermal poob siab, thiab nws muaj zog oxidizing zog thiab zoo tshaj rau lub teb chaws thiab kev lag luam qauv. Cov khoom tau dhau qhov kev tshuaj xyuas ntawm National Graphite Product Quality Supervision and Inspection Center.
