Calcined roj ceke uses

Xam cov roj ceke uses ua tus kab mob carburizing: Cov ntsiab lus carbon doge, tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus hluav taws xob yuav tsum tau hloov kho raws li cov cai ntawm cov qauv steel sib txawv. Xam roj Coke yog ib tus carburizer zoo tshaj plaws nrog cov pa roj carbon ntau thiab tsawg dua impurities. Nws tuaj yeem ua kom sai thiab ua kom tau zoo ntxiv cov ntsiab lus carbon hauv kua, hardness, kev nruj me ntsis ntawm cov hlau, kom tau raws li qhov ua tau zoo ntawm cov khoom siv steel.
Xam cov roj ceke uses txo tus neeg sawv cev: hauv qee cov ferrroalloy kev tsim khoom thiab cov hlau tshwj xeeb smelting, calcined roj coke tuaj yeem siv los ua tus neeg sawv cev. Nws tuaj yeem raug txo nrog cov hlau oxides, txo cov hlau los ntawm nws cov oxides, ua kom tiav cov hlau rho nyiaj ntau xws li ferrosilican thiab ferromanganese.
Graphite cov khoom lag luam.
Nyob rau hauv cov tshuaj lom neeg cov tshuaj: calcined roj av coke siv los tsim cov ntaub ntawv raw tseem ceeb xws li silicon carbide. Nyob rau hauv cov kev mob siab, silicon carbide reacts nrog lwm cov yam ntxwv uas muaj zog, yog ib qho tseem ceeb ua rau cov khoom muaj sia, Ib qho ntxiv, nws kuj tseem tuaj yeem siv los ua lwm cov carbides, cov khoom siv carbon thiab lwm yam khoom siv tshuaj lom neeg.
