Graphitized roj av cokeyog ib qho graphitized carbon additive siv los ntawm cov khoom siv carbon tshiab thiab zoo nyob rau hauv kev lag luam metallurgical, cub tawg lossis qhov cub (dawb).Kev ua haujlwm hauv cov txheej txheem ntawm cov hlau ua, tuaj yeem txo cov pa roj carbon ntsiab lus hauv cov hlau kom tau txais cov khoom tsim nyog molten steel, los ntawm cov khoom siv sib txawv, xws li carburizing tus neeg sawv cev feem ntau yog siv metallurgical coke, roj av coke yog ntxiv rau hauv cov roj hmab asphalt qis. , calcined carbon, vim hais tias cov ntaub ntawv no yog tsawg haum tus nqi, siab sulfur cov ntsiab lus, Qhov tam sim no yog ib qho nyuaj los xyuas kom meej lub stability ntawm lub siab xav steel zoo nyob rau hauv ntau dua steelmaking txheej txheem.

　　Hom neeg siv khoom

Hlau thiab hlau smelting, casting, lag luam nruab nrab.

Lub cev daim ntawv

Cov tsos mob huv si, tsis muaj impurities, particle loj uniformity (kwv yees li 1.5MM), tuaj yeem yog los ntawm ntau tus neeg tau txais kev paub ntau xyoo, tsawg dua 5 tons ntawm qhov nruab nrab zaus qhov cub siv, tus nqi nqus dej, tus nqi nqus;Daim ntawv: Crystal zoo, cam khwb cia hlau qib thiab zoo txhim khu cov khoom ntawm siab ruaj ruaj carbon, absorptivity, tsis tshua muaj sulfur, nitrogen, thiab sai dua li graphitized carbon tus neeg saib xyuas ntawm tus nqi nqus, adsorption furnace phab ntsa tsis tiav absorption yam tsis muaj residue, tus nqi yog tsawg dua. zoo sib xws sulfur graphitized carbon additives hauv qab 0.05, nrog cov nqi qis dua.

Tshuaj ntsuam xyuas

Tus nqi nqus, siv qhov nqus siab tshaj plaws tuaj yeem ncav cuag 95% raws li.Kev nqus nrawm nrawm, nrawm dua li qhov zoo sib xws ntawm graphitization carburizing tus neeg saib xyuas kev nqus nrawm, tsis muaj cov phab ntsa adsorption, thiab tsis muaj qhov seem, qhov cub carburizing nqus qhov zoo dua yog qhov pom tseeb dua.Nitrogen uas tsis muaj leej faj, 0.03% lossis tsawg dua, tus nqi siab, hauv cov neeg ua haujlwm graphitizing zoo sib xws (sulfur ≦0.05) tus nqi zoo tshaj plaws ntawm cov tshuaj xyuas saum toj no.

Cov txiaj ntsig cuam tshuam

Graphite carburizing tus neeg sawv cevrau koj kom txo tau cov nqi, txhim kho cov khoom zoo.Cov ntaub ntawv nyoos tuaj yeem ua rau cov khoom seem ntawm cov hlau, txo cov npua hlau los yog tsis muaj hlau, kom tsis txhob muaj kev cuam tshuam ntawm cov caj ces hlau castings.Tsis tshua muaj leej faj, cov pob sulfur yog txhim khu kev qha, muaj kev tiv thaiv zoo thiab nyob rau hauv cov hlau alloy, alloy txuag nqi ntawm kev tsis zoo ntawm kev yug me nyuam.Vim qhov qis melting point, nqus tus nqi, tsis muaj slag, tuaj yeem tiv thaiv thiab ua kom lub neej ntev ntawm lub cub tawg, txo cov khoom siv hauv ob sab phlu, ntshiab tshuaj muaj pes tsawg leeg: carbon, sulfur, nitrogen micro, ruaj khov khoom tsis muaj teeb meem impurities, carburizing nyhuv. ruaj khov, zoo absorbing nyhuv, kub nyhuv yog pom tseeb, tsis muaj slag rov qab.
