600mm Graphite Electrode Composition

Dab tsi txhais cov khoom pleev xim ntawm 600mm Graphite Electrode

Sab hauv architecture ntawm 600mm graphite electrode pib nrog ib daim ntawv qhia ua tib zoo sib npaug ntawm carbonaceous raw cov ntaub ntawv. Tsis zoo li me me - txoj kab uas hla sib txawv, hom 600mm yuav tsum txhawb nqa qhov tshwj xeeb tam sim no loads hauv hluav taws xob arc rauv, uas tso cov kev xav tau tshwj xeeb rau txhua qhov chaw hauv nws cov muaj pes tsawg leeg. Cov neeg tsim khoom yog li xaiv thiab faib cov khoom sib xyaw nrog qhov tseeb, paub tias txawm tias qhov hloov pauv me me hauv cov khoom siv raw zoo lossis cov sib xyaw sib xyaw txhais ncaj qha rau hauv qhov ntsuas qhov sib txawv ntawm cov khoom siv hluav taws xob, lub zog siv hluav taws xob, thiab thermal cwj pwm hauv qab arc.

Cov Khoom Siv Tseem Ceeb thiab Lawv Lub Luag Haujlwm

Peb pawg ntawm cov ntaub ntawv tsim cov pob txha ntawm txhua 600mm graphite electrode: aggregate fillers, binder systems, thiab functional additives. Txhua pawg ua tiav lub hom phiaj sib txawv thaum tsim, ci, thiab graphitization.

Petroleum cokeua hauj lwm raws li tus thawj xib fwb aggregate. Muab tau los ntawm ncua sij hawm coking ntawm cov roj residual hnyav, cov khoom siv no muab cov pob txha carbon ntau. Nws cov qauv microcrystalline, cov ntsiab lus tsis hloov pauv, thiab qib sulfur txiav txim siab npaum li cas lub cev ntsuab hloov mus rau hauv graphitic lattice thaum lub sij hawm siab -kub kho. Rau UHP- qib 600mm electrodes, calcined petroleum coke uas tsis tshua muaj leej faj thiab cov hlau tsis huv yog nyiam, vim tias cov khoom tsis huv cuam tshuam kev loj hlob ntawm graphite crystallites.

Koob cokesawv cev rau qhov kev xaiv premium filler. Nws qhov tshwj xeeb fibrous microstructure, tsim los ntawm cov txheej txheem coking tshwj xeeb, yields anisotropic zog uas ua kom zoo raws li cov electrode axis. Thaum muab sib xyaw rau hauv qhov sib xyaw ua ke rau loj - txoj kab uas hla electrodes, koob coke txhim kho lub zog flexural thiab txo cov coefficient ntawm thermal expansion. Lub superior graphitizability ntawm koob coke kuj pab txo cov hluav taws xob resistivity nyob rau hauv cov khoom tiav.

Coal tar pitchua haujlwm raws li theem binder. Thaum sib tov, cov kua pitch coats ib tug neeg aggregate hais thiab sau inter-granular voids. Thaum carbonization nyob rau hauv lub ci theem, lub suab no - muab cov pa roj carbon MAAs hloov mus rau hauv ib qho khoom siv choj uas kaw cov pob txha pob txha nyob rau hauv qhov chaw. Cov ntsiab lus muag muag, tus nqi coking, thiab quinoline- cov ntsiab lus tsis sib haum ntawm lub suab tswj xyuas qhov zoo ntawm cov ntawv cog lus carbon nrog cov khoom muab tub lim. Tus nqi coking siab yog qhov xav tau vim nws tawm hauv qab cov pa roj carbon ntau dua tom qab volatiles khiav.

Cov txheej txheem Evolution Thaum tsim khoom

Txoj kev taug kev los ntawm cov khoom siv raw sib xyaw kom tiav 600mm electrode cuam tshuam nrog cov qauv tsim kho kom zoo. Nyob rau hauv lub ntsuab theem, lub cev muaj uncalcined suab nyob ib ncig ntawm discrete coke hais. Thaum lub sij hawm ci ntawm qhov kub txog li ib txhiab degrees Celsius, lub suab undergoes pyrolysis. Volatile hydrocarbons evolve, tawm hauv qab cov pa roj carbon matrix uas sib txuas cov nplej uas nyob ib sab.

Cov kauj ruam tom ntej graphitization, ua nyob rau hauv qhov kub siab tshaj nees nkaum- xya puas degrees Celsius, ua rau muaj kev hloov pauv loj tshaj plaws. Nyob rau hauv cov txheej txheem thermal no, cov pa roj carbon tsis zoo maj mam rov ua dua rau hauv hexagonal graphite lattice. Lub℃ntawm graphitization ncaj qha cuam tshuam nrog thermal conductivity thiab hluav taws xob conductivity. Lub qhov dej -graphitized 600mm electrode nthuav tawm graphitization qib siab tshaj cuaj caum- yim feem pua, uas piav qhia nws lub peev xwm nqa cov tam sim no hnyav yam tsis muaj cua sov ntau dhau.

Yuav ua li cas Composition Translates rau Performance Metrics

Txhua yam cuab yeej ntsuas tau ntawm cov khoom tiav electrode rov qab mus rau kev txiav txim siab ntawm cov txheej txheem tsim.Hluav taws xob resistivitynyob ntawm feem ntau ntawm cov graphitization℃thiab purity ntawm cov aggregate. Cov koob ntau dua coke cov ntsiab lus thiab ua tiav graphitization ob qho tib si tsav resistivity downward.Qhov ntom ntomqhia txog kev ntim khoom ntawm kev sib xyaw ua ke thiab cov pa roj carbon yield ntawm cov ntawv khi. Qhov ntom ntom microstructures tiv thaiv oxidation zoo dua thiab ua kom sov tau zoo dua.Flexural zogtshwm sim los ntawm kev ncaj ncees ntawm cov sib sau ua ke-binder interface thiab kev taw qhia ntawm anisotropic muab tub lim. Thaum kawg, tuscoefficient ntawm thermal expansionyog muaj zog cuam tshuam los ntawm qhov piv ntawm koob coke rau roj av coke, vim hais tias cov fibrous morphology ntawm koob coke restrains dimensional hloov thaum lub sij hawm thermal cycling.

UHP Qib Specifications (YB/T 4090-2000)

Kev Ntsuam Xyuas Zoo thiab Batch Consistency

Txhua pawg ntau lawm ntawm 600mm graphite electrodes undergoes kev txheeb xyuas kev txheeb xyuas. Cov ntaub ntawv nyoos raug tshuaj xyuas cov sulfur, tshauv, thiab cov ntsiab lus tsis haum ua ntej nkag mus rau hauv cov kab sib xyaw. Lub cev ntsuab raug tshuaj xyuas seb qhov sib txawv ntawm qhov ntom ntom. Tom qab ci, cov qauv raug kuaj rau porosity thiab mechanical kev ncaj ncees. Qhov kawg graphitization theem yog saib xyuas ntawm qhov kub thiab txias profile kom paub meej tias ua tiav crystalline reorganization. Cov electrodes tiav lawm tau soj ntsuam thiab raug rau hluav taws xob resistivity thiab flexural zog kuaj ua ntej tso tawm.
