Kev lag luam siab zog graphite electrode yog tsav los ntawm qhov sib npaug ntawm cov khoom seem -raws li steelmaking muaj peev xwm, muab cov coke zoo, thiab lub zog nqi ntawm graphitization. Tag nrho peb txoj kev txav mus rau ntau lub voj voog, uas yog vim li cas tus nqi rau HP thiab UHP electrodes tuaj yeem hloov pauv txawm tias cov khoom siv hlau yog tiaj tus. Cov hauv qab no yog cov qauv nyeem ntawv ntawm lub zog uas tsim cov khoom siv, kev xav tau thiab tus nqi, nrog rau cov ntsuas tus neeg yuav khoom yuav tsum tau saib xyuas.
Khoom Muag: Coke, Graphitization thiab Zog
Cov khoom noj tseem ceeb rau cov qib UHP yog koob coke, uas nws muaj thiab ua tau zoo tau teeb tsa lub qab nthab ntawm cov txiaj ntsig zoo. Cov ntsiab lus sulfur thiab puffing tus cwj pwm ntawm calcined coke cuam tshuam tawm los thiab tsis lees paub, thiab coke sulfur yog ntsuas los ntawm ASTM D4239 hauv kev tswj kom zoo. Graphitization yog lub zog tshaj plaws - cov kauj ruam tseem ceeb hauv kev tsim khoom, yog li tus nqi hluav taws xob hauv kev tsim cov cheeb tsam pub ncaj qha rau hauv cov nqi hluav taws xob. Environmental retrofits thiab emissions tswj ntxiv peev nqi rau ci thiab graphitization kab, thiab lawv kuj txo cov zis muaj nyob rau lub sij hawm upgrade.
Tus nqi tsim thiab zoo txaus ntshai
HP thiab UHP electrode tus nqi yog sib tham raws li daim ntawv cog lus thiab feem ntau indexed rau cov khoom siv raw thiab cov nqi hluav taws xob es tsis yog qhov chaw tsav tsheb. Thaum cov nqi nce sai, cov khoom siv tsis zoo tuaj yeem nkag mus rau hauv kev ua lag luam, tus cwj pwm los ntawm kev tiv thaiv ntawm qhov kawg ntawm cov qhab, cov tshauv ntau dua, lossis cov txiv mis tsis muaj zog. Cov neeg yuav khoom txo qhov kev pheej hmoo los ntawm kev xav tau daim ntawv pov thawj zeb kuaj ib tus naj npawb cua sov thiab los ntawm kev ntsuas kev tiv thaiv, ntom thiab lub zog tiv thaiv cov duab pom zoo. Tus nqi sib txawv ntawm kaum tsib mus rau nees nkaum feem pua ntawm RP thiab HP lossis UHP qib yog qhov qub thiab yuav tsum raug ntsuas tawm tsam kev noj hauv kilograms ib tonne ntawm cov hlau, tsis yog tawm tsam tus nqi ib leeg.

Cov lus nug nquag
Q:Dab tsi yog tus tsav tsheb loj tshaj plaws ntawm HP electrode xav tau?
A: Hluav taws xob arc rauv hlau tso zis. Cov hluav taws xob tau siv rau hauv kev faib ua feem rau lub sijhawm ua haujlwm ntawm lub cub hluav taws xob thiab lub zog- raws sijhawm, yog li kev siv EAF yog qhov kev xav tau tseem ceeb.
Q:Vim li cas UHP cov nqi sib cais los ntawm RP nqi?
A: Lawv siv cov khoom sib txawv. Cov qib UHP xav tau koob coke, uas nws cov khoom muaj ntau dua thiab ntau dua cyclical dua li daim txhuam cev coke siv rau cov hluav taws xob tsis tu ncua.
Q:Kev noj ib txwm qhia li cas?
A: Nyob rau hauv kilograms ntawm electrode ib tonne ntawm kua hlau. Kev lag luam kev coj ua feem ntau qhia txog qhov tseem ceeb ntawm kwv yees li ib mus rau peb kilograms ib tonne, nrog rau kev xyaum UHP niaj hnub nyob rau hauv qis kawg ntawm qhov ntau.
Q:Qhov kev pheej hmoo zoo li cas nce thaum lub lag luam nruj?
A: Siab tshaj qhov pom zoo tiv thaiv, nce tshauv, qhov sib txawv ntawm qhov sib txawv thiab cov khoom siv mis tsis muaj zog. Kev tshuaj xyuas thiab cua sov- daim ntawv pov thawj tus lej yog qhov tseem ceeb tiv thaiv.
Q:Puas yog tus nqi ib leeg yog qhov laj thawj zoo los hloov tus neeg muag khoom?
A: Tsis yog. Kev siv, kev tawg thiab qhov cub muaj qhov cuam tshuam loj dua rau tus nqi ib tonne ntawm cov hlau ntau dua li qhov hloov me me ntawm cov nqi hluav taws xob.
