Graphite petroleum coke recarburizer yog cov khoom siv carbon uas feem ntau siv hauv cov txheej txheem steel smelting. Nws yog tsuas yog siv los ua kom cov pa roj carbon ntau hauv cov hlau thiab txhim kho nws cov khoom siv dag zog thiab hnav tsis kam. Cov hauv qab no yog qee yam ntawm cov yam ntxwv tseem ceeb ntawm graphite roj av coke recarburizer:
1. Cov ntsiab lus siab carbon: Cov ntsiab lus ruaj khov ntawm graphite petroleum coke recarburizer yog qhov siab, feem ntau ncav cuag ntau dua 98.5%, thiab qee cov khoom tuaj yeem ncav cuag 99%. Qhov no ua rau nws zoo heev hauv kev nce cov ntsiab lus carbon ntawm castings, kev txhim kho cov khoom siv ntawm cov hlau castings, thiab txhim kho hardness thiab hnav tsis kam.
2. Cov ntsiab lus tsis tshua muaj leej faj: Cov ntsiab lus ntawm cov tooj liab ntawm cov roj av zoo graphite coke recarburizer tuaj yeem qis li 0.01-0.05%. Cov ntsiab lus tsis muaj leej faj yog qhov tseem ceeb rau kev txhim kho lub zog ntawm cov hlau thiab tiv thaiv brittleness, tawg thiab lwm yam teeb meem ntawm cov hlau.
3. Cov ntsiab lus tsis tshua muaj nitrogen: Cov ntsiab lus nitrogen ntawm graphite roj av coke recarburizer yog ruaj khov ntawm 80PPM thiab 250PPM, uas yog tsim los ua cov khoom siv zoo tshaj plaws rau cov hlua hlau, uas muaj cov txiaj ntsig zoo ntawm kev txo qhov pores thiab lwm yam tsis xws luag hauv castings.
4. Cov ntsiab lus tsis tshua muaj dej noo: Cov graphitized roj av coke recarburizer muaj cov dej noo tsawg, uas yuav pab txo cov solubility thiab porosity ntawm hydrogen hauv hlau.
5. High absorption rate: Lub graphitized petroleum coke recarburizer muaj cov khoom me me, qhov porosity loj, nqus nrawm nrawm, thiab feem ntau muaj qhov nqus ntawm ntau dua 95%, uas zoo dua li cov recarburizers zoo sib xws, uas txhais tau tias tsawg dua cov pa roj carbon monoxide thaum lub smelting. txheej txheem thiab txhim kho cov txiaj ntsig kev lag luam.
6. Lub cev thiab cov khoom siv tshuaj lom neeg: Cov graphitized petroleum coke recarburizer muaj cov block dub lossis granular zoo li thiab muaj zog hardness thiab siab ceev. Nws lub cev thiab tshuaj lom neeg muaj xws li zoo dispersibility, stability thiab uniformity.
7. Daim ntawv thov dav: Graphitized petroleum coke recarburizer yog dav siv nyob rau hauv foundries (grey cam khwb cia hlau thiab high-end ductile hlau casting), steel mills (steel ntau lawm), metallurgical nroj tsuag, tsheb thiab tsheb qhov chaw manufacturers (brake pads, lub tog raj kheej liner thiab camshaft. manufacturing, thiab lwm yam).
8. Kev txuag hluav taws xob thiab kev txo qis: Vim nws qhov nqus tau siab thiab ceev cov tshuaj tiv thaiv ceev, kev siv graphitized roj av coke recarburizer tuaj yeem txo lub sijhawm smelting thiab ua tiav cov txiaj ntsig ntawm kev txuag hluav taws xob thiab kev txo qis. Nyob rau tib lub sijhawm, nrog rau kev nce qib ntawm cov khoom siv thev naus laus zis tshiab, graphitized petroleum coke recarburizer yuav txhim kho mus rau siab dua purity thiab qis dua cov ntsiab lus impurity.
9. Txhim kho kev ua haujlwm casting: Siv cov graphitized petroleum coke recarburizer tuaj yeem txhim kho cov khoom siv ntawm cov hlau castings, txo qis shrinkage nyiam, thiab txhim kho kev ua haujlwm.
10. High-temperature graphitization treatment: Graphitized petroleum coke recarburizer yog rhuab ntawm qhov kub ntawm 2200-2600 degree los hloov cov amorphous chaotic txheej qauv carbon ntawm roj av coke rau hauv peb-dimensional xaj graphite crystals. Qhov kub ntawm cov roj av coke recarburizer yog li ntawm 1300 degrees, thiab nws tsis ua raws li cov txheej txheem graphitization.
Hauv cov ntsiab lus, graphite roj av coke recarburizer muaj qhov sib txawv tseem ceeb ntawm lwm cov recarburizers hauv cov txheej txheem tsim khoom, cov yam ntxwv zoo li, cov khoom siv purity, kev siv cov nyhuv, qhov nqus thiab cov nqi zoo. Cov kev sib txawv no ua rau graphite roj av coke recarburizer nrov heev nyob rau hauv metallurgical thiab casting industries thiab cov khoom tseem ceeb rau kev txhim kho cov khoom zoo thiab kev ua tau zoo.
