Muaj ob lub laj thawj tseem ceeb vim li cas peb suav nrog carbureisers hauv cov txheej txheem steelmaking. Ua ntej, lawv ua kom cov hlau muaj cov ntsiab lus carbon zoo. Lawv kuj ua rau tag nrho cov txheej txheem zoo dua.
Carburizers yog cov khoom uas muaj cov ntsiab lus siab carbon. Lawv ua kom nws muaj peev xwm nce cov ntsiab lus carbon ntawm molten steel. Thaum lub sij hawm tus txheej txheem, cov pa roj carbon ntsiab lus ntawm molten hlau yuav txo tau vim oxidation, yog li ntxiv carburizers zoo compensates rau qhov no. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog rau high-carbon steels, xws li cov cuab yeej steel thiab bearings, qhov twg cov ntsiab lus carbon yuav tsum tau pom.
Qhov thib ob, lawv tuaj yeem txhim kho koj ua cov hlau zoo li cas. Thaum koj ua cov hlau, cov carburizers hnov mob nrog cov pa oxygen hauv cov hlau molten los ua carbon monoxide, uas tom qab ntawd txo cov pa oxygen ntawm cov hlau molten. Cov tshuaj tiv thaiv no ua rau cov txheej txheem oxidation ntawm cov hlau molten thiab ua rau cov oxidation ntau dua, ua rau cov hlau ua tau zoo dua.
Lawv kuj pab txhim kho cov hlau zoo. Lawv muaj cov pa roj carbon ntau, thiab qis hauv sulfur thiab phosphorus, uas txhais tau hais tias lawv tuaj yeem txo cov sulfur thiab phosphorus hauv cov hlau. Qhov no ua rau cov hlau ntshiab dua thiab zoo dua. Lawv kuj ua rau cov hlau hnyav dua thiab tiv taus ntau dua rau hnav thiab tsim kua muag, uas yog vim li cas lawv tau siv ntau los ua kom muaj zog thiab ruaj khov qhov chaw.
