Cov tub ntxhais hlau yog cov hlau sib txuas uas sib txuas ua ke cov hlau cores nrog cov ntaub ntawv tsis yog xim hlau, dav siv hauv kev nruam casting thiab ua cov txheej txheem hauv kev lag luam xws li hlau, tsis-ferrous hlau, iav, ceramics, thiab lwm yam. xov hlau yog qhov tseem ceeb heev rau kev txhim kho cov khoom zoo thiab kev ua haujlwm zoo. Vim nws cov ntsiab lus carbon zoo thiab ruaj khov, graphite carbonization tus neeg sawv cev tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev kho carbonization ntawm cov tub ntxhais hlau.
Graphite carburizer yog cov ntxhia uas tsis yog xim hlau nrog cov purity siab thiab ruaj khov carbon cov ntsiab lus, thiab nws cov qauv molecular yog C. Nws muaj lub cev zoo thiab tshuaj lom neeg ruaj khov, tuaj yeem tuav cov ntsiab lus ruaj khov ntawm qhov kub thiab txias, thiab nws tsis yooj yim rau kev tsim cov pa roj carbon monoxide. impurities. Tsis tas li ntawd, graphite carburizer muaj lub siab melting point thiab resistivity, thiab muaj zoo conductivity thiab corrosion kuj
Muab cov tub ntxhais sib xyaw ua ke rau hauv lub qhov cub melting thiab ua kev kho melting ntawm qhov kub thiab txias. Thaum lub sij hawm melting txheej txheem, kub thiab lub sij hawm yuav tsum tau tswj xyuas kom meej tias cov graphite carbonization tus neeg sawv cev yog tag melted thiab tag nrho ua ke nrog cov tub ntxhais hlau. Qhov ntsuas kub thiab siab tsim nyog yuav tsum tau tswj xyuas thaum lub sij hawm casting txheej txheem kom tau ib tug ntom thiab high-kev ua tau zoo core hlau.
