Xav kom nkag siab tias tus neeg sawv cev carburizing yog cov khoom siv, pib los ntawm cov khoom siv carburizing tus neeg sawv cev raw khoom txuas.Tam sim no, feem ntau siv carburizing tus neeg saib xyuas hauv khw yog calcined roj av coke carburizing tus neeg saib xyuas thiab graphitized carburizing tus neeg saib xyuas.

1. Calcined roj av cokecarburizer yog cov roj av coke uas yog calcined ntawm 1250 ℃ rau 48 teev thiab ua calcined roj av coke.Nyob rau hauv tag nrho cov txheej txheem, cov impurities xws li volatile teeb meem thiab ya raws ntawm roj av coke raug tshem tawm, thiaj li hais tias cov pa roj carbon ntsiab lus yuav ncav cuag ntau tshaj 98.5% thiab impurities xws li volatile teeb meem thiab tshauv yuav txo tau tsawg tshaj li 1.5%.Carburizing tus neeg sawv cev cov ntaub ntawv los ntawm cov tsos ntawm tsis zoo li coke, qhov luaj li cas ntawm cov dub thaiv (los yog hais), nws yog xim hlau luster, hais nrog porous qauv, lub ntsiab ntsiab lus muaj pes tsawg leeg ntawm carbon.

2. Graphitization carburizing tus neeg sawv cev yog cov khoom tau los ntawm cov roj av coke lossis calcined petroleum coke tom qab kev kho kub kub los ntawm cov txheej txheem graphitization ntawm 3000 ℃.Qhov sib txawv ntawm cov txheej txheem calcination thiab cov txheej txheem calcination yog tias cov qauv molecular ntawm cov pa roj carbon hloov pauv zoo heev, thiab cov qauv yog nruab nrab ntawm cov qauv amorphous thiab cov qauv graphite, uas yog ib qho kev tsis sib haum xeeb superimposed amorphous qauv.Graphitized carburizer cov ntaub ntawv los ntawm cov tsos ntawm calcined ntau xim dub thiab ci, thiab tuaj yeem sau cov lus zoo ntawm daim ntawv.

Nyob rau hauv luv luv, cov khoom siv carburizer tsuas yog pom tau tias yog ib hom carbon qauv ntawm cov qauv amorphous thiab graphite qauv ntawm cov khoom siv carbon.
