Lub ntsiab siv roj av coke
Cov ntawv thov tseem ceeb ntawm cov roj av coke yog ua ntej ci anode thiab anode paste siv hauv electrolytic aluminium, carbon kev lag luam, graphite electrode, industrial silicon smelting thiab roj.
Raws li cov qauv thiab cov tsos ntawm roj av coke, cov khoom siv roj av coke tuaj yeem muab faib ua plaub hom: (1) Koob coke, nrog cov qauv siv dav dav thiab fiber ntau, feem ntau yog siv los ua lub zog siab thiab ultra-siab zog graphite electrode hauv steel ua. . Cov txheej txheem tsim khoom thiab cov khoom siv raw ntawm rab koob coke muaj cov kev cai tshwj xeeb vim qhov kev ntsuas nruj nruj hauv cov ntsiab lus sulfur, tshauv, cov teeb meem tsis hloov pauv thiab qhov ntom ntom. (2) Daim txhuam cev coke, nrog cov tshuaj lom neeg muaj zog thiab cov ntsiab lus tsis zoo, feem ntau yog siv hauv kev lag luam txhuas thiab kev lag luam carbon. (3) Projectile coke los yog spherical coke: round spherical nyob rau hauv cov duab, 0 6-30mm inch, feem ntau yog tsim los ntawm high sulfur, siab asphaltene residue, thiab tsuas yog siv tau raws li industrial roj rau lub hwj chim tiam. , cement, thiab lwm yam. (4) hmoov coke: Ua los ntawm cov txheej txheem coking fluidized, nws muaj cov khoom zoo (0.1-0.4mm inch), cov ntsiab lus siab tsis hloov pauv thiab siab thermal expansion coefficient, thiab tsis tuaj yeem siv ncaj qha rau hauv kev npaj electrode thiab carbon kev lag luam.
Raws li qhov sib txawv ntawm cov ntsiab lus sulfur, nws tuaj yeem muab faib ua cov sulfur coke siab (cov ntsiab lus sulfur siab dua 3 feem pua) thiab qis sulfur coke (cov ntsiab lus sulfur hauv qab 3 feem pua). Tsawg sulfur coke tuaj yeem siv ua anode muab tshuaj txhuam thiab ua ntej ci anodes rau cov nroj tsuag txhuas thiab graphite electrodes rau cov nroj tsuag steel. Ntawm lawv, zoo siab qis sulfur coke (tsawg dua 0.5 feem pua sulfur) tuaj yeem siv los tsim cov graphite electrodes thiab carbon enhancers. Tsawg sulfur coke (cov ntsiab lus sulfur tsawg dua 1.5 feem pua) feem ntau yog siv los tsim cov anodes prebaked. Cov roj av tsis zoo coke feem ntau yog siv rau smelting industrial silicon, silicon carbide thiab ua anode paste. High sulfur coke feem ntau yog siv los ua roj rau cov nroj tsuag cement thiab fais fab nroj tsuag.
Calcined petroleum coke: Nyob rau hauv graphite electrode rau steel ua los yog anode paste (fused electrode) rau txhuas thiab magnesium ua, thiaj li yuav hloov cov roj av coke (raw coke) rau qhov yuav tsum tau, cov raw coke yuav tsum tau calcined. Calcination kub feem ntau nyob ib ncig ntawm 1300 degree, lub hom phiaj yog kom tshem tawm cov roj av coke volatile ntsiab lus ntau npaum li sai tau. Qhov no txo cov ntsiab lus hydrogen ntawm roj av coke reproducts thiab ua rau cov roj av coke ntau graphitized, yog li kev txhim kho qhov kub thiab txias zog thiab kub tsis kam ntawm graphite electrodes thiab txhim kho cov hluav taws xob conductivity ntawm graphite electrodes. Calcined coke yog tsuas yog siv nyob rau hauv zus tau tej cov graphite electrode, carbon paste khoom, pob zeb diamond, zaub mov qib phosphorus kev lag luam, metallurgical kev lag luam thiab calcium carbide, thiab lwm yam. Qhov feem ntau siv ib tug graphite electrode. Raw coke tuaj yeem siv ncaj qha rau calcium carbide ua cov khoom tseem ceeb ntawm calcium carbide, silicon carbide thiab boron carbide ua cov khoom siv tsis muaj forging. Nws tseem tuaj yeem siv ncaj qha los ua coke rau lub qhov cub tawg lossis tawg rau lub qhov cub phab ntsa hauv cov pa roj carbon cij hauv kev lag luam metallurgical, thiab ua cov coke ntom rau cov txheej txheem casting, thiab lwm yam.
