Cov txiaj ntsig tseem ceeb ntawm kev siv calcined petroleum coke thiab graphitized petroleum coke nyob rau hauv foundries yog raws li nram no:

1. Ob qho tib si calcined roj av coke thiab graphitized roj av coke yog high-purity carbon cov ntaub ntawv uas muaj calorific nqi, tsis muaj tshauv cov ntsiab lus, tsis volatile teeb meem thiab tsis muaj leej faj cov ntsiab lus, yog li lawv muaj peev xwm lav tau zoo ntawm casting khoom.

2. Calcined petroleum coke thiab graphitized petroleum coke muaj cov tshuaj lom neeg ruaj khov, tsis yooj yim oxidized, thiab tuaj yeem tiv taus oxidation, corrosion thiab kub erosion.

3. Calcined petroleum coke thiab graphitized petroleum coke muaj cov duab zoo li qub thiab qhov loj, qhov loj ntawm qhov chaw, muaj zog adsorption kev ua tau zoo, tuaj yeem sib xyaw zoo nrog lwm cov ntaub ntawv batch, thiab xyuas kom cov pa roj carbon zoo sib xws hauv kev ua haujlwm.

4. Calcined petroleum coke thiab graphitized petroleum coke muaj hluav taws xob conductivity thiab muaj peev xwm ua tau hluav taws xob zoo, uas yog ib qho tseem ceeb heev rau kev kho electrothermal hauv cov txheej txheem casting.

Muaj ntau lwm yam kev lag luam thiab kev lag luam uas siv calcined petroleum coke thiab graphitized roj av coke.Cov hauv qab no yog qee qhov kev siv ib txwm:

1. Hlau thiab steel kev lag luam: Calcined roj av coke thiab graphitized roj av coke yog lub ntsiab txo tus neeg sawv cev thiab carbon qhov chaw nyob rau hauv lub steelmaking txheej txheem.Lawv tuaj yeem txo cov ntsiab lus oxide hauv tus nqi thiab txhawb kev txo cov tshuaj tiv thaiv, yog li txhim kho kev ua haujlwm ntawm steelmaking thiab cov hlau zoo.

2. Kev lag luam tshuaj: calcined petroleum coke thiab graphitized petroleum coke tuaj yeem siv los ua catalyst carrier lossis adsorbent.Lawv cov porosity siab, qhov loj ntawm qhov chaw thiab kev ua haujlwm zoo adsorption tuaj yeem ua kom zoo los yog adsorb cov tshuaj hauv cov tshuaj tiv thaiv, txhim kho cov tshuaj tiv thaiv thiab kev ua haujlwm zoo.

3. Txheej kev lag luam: Calcined roj av coke thiab graphitized petroleum coke yog siv los ua fillers los yog thickeners hauv coatings.Lawv tuaj yeem txhim kho hardness, gloss thiab corrosion kuj ntawm coatings, thaum txo tus nqi ntawm coatings.

4. Kev lag luam tsheb: Calcined petroleum coke thiab graphitized petroleum coke tuaj yeem siv los ua cov pa roj carbon fiber ntau thiab nws cov ntaub ntawv sib xyaw, thiab siv los tsim cov khoom muaj zog thiab lub teeb yuag, xws li lub cev thiab chassis.
