Yuav ua li cas yog cov pa hluav taws xob rau qhov kub thiab txias?

Cov pa roj carbon electrode rau high - sov daim ntawv thov tsim kom muaj cov pa hluav taws cua, xws li cov txheej txheem hluav taws xob, thiab cov tshuaj lom neeg. Tsis zoo li graphite electrodes, uas yog cov tshuaj pab roj carbon, cov pa roj carbon monoxide cov roj av yog ib txwm ua los ntawm kev ua kom zoo nkauj roj av, ua rau muaj kev cuam tshuam me ntsis tab sis ntau dua kev tiv taus rau qee yam tshuaj lom neeg. Cov hluav taws xob no tau siv dav hauv kev lag luam qhov chaw huab cua sov (feem ntau tshaj li 2,632 degree, thiab lwm yam siab {{techures tshuaj.

Thawj qhov txiaj ntsig ntawm cov roj carbon electrodes hauv high - sov daim ntawv thov yog lawv muaj peev xwm tiv thaiv cua sov thiab tshuaj lom neeg zoo dua li qee cov ntaub ntawv. Lawv feem ntau siv nyob rau hauv submerged arc rawg hluav taws (kev nyab xeeb) rau cov khoom siv hluav taws xob, uas siv hluav taws xob kom tsim hluav taws xob los ntawm thaj chaw tiv thaiv. Cov txheej txheem carbon electrodes tseem ua haujlwm hauv Zinc Smelting thiab lwm cov txheej txheem metallurgical uas lawv lub durability thiab tus nqi} ua tau zoo.

Thaum cov roj hluav taws xob muaj hluav taws xob muaj hluav taws xob siab dua li kev siv hluav taws xob graphite, lawv muaj kev lag luam ntau dua rau qee cov ntawv thov. Lawv feem ntau yog tsim los ntawm cov khoom siv roj carbonapaceous, sib sau ua ke rau hauv cov pas nrig lossis balling lawv ntawm qhov siab kom ua tiav lub hardness thiab conductivity. Txawm hais tias lawv cov kev txwv, cov khoom siv roj carbon ntau nyob rau hauv high- Cov txheej txheem ntawm lawv cov txiaj ntsig ntawm cov txiaj ntsig ntawm cov txiaj ntsig ntawm graphite. Kev tswj hwm kev tu thiab kev tswj hwm hluav taws xob yog qhov tseem ceeb kom ntseeg tau tias muaj txiaj ntsig thiab kev ua haujlwm rauv.
