Dab tsi yog qhov ntsuas ntawm thee carburizer rau steelmaking?
Sep 13, 2024Tso lus
1. Cov ntsiab lus sulfur
Nyob rau hauv steelmaking thee carburizer, leej faj lub ntsiab (cov cementite ruaj khov) ua lub luag haujlwm hauv kev tiv thaiv kev nthuav dav ntawm graphitization, thaum cov ntsiab lus sulfur ntawm steelmaking thee carburizer siab dhau lawm, nws yuav cuam tshuam rau cov nyhuv nodularization thiab haus ntau cov nodulator hauv kev tsim khoom, yog li ua kom cov khoom lag luam nce ntxiv. tus nqi ntawm steelmaking, yog li nws yog ib qho tsim nyog los xaiv cov thee carburizer nrog cov ntsiab lus tsis tshua muaj leej faj rau steelmaking.
2. Tsau carbon, tshauv, cov ntsiab lus volatile
Cov pa roj carbon monoxide ruaj khov ntawm cov khoom siv hluav taws xob siv hauv steelmaking yog xam raws li cov ntsiab lus ntawm cov dej, volatile, tshauv thiab leej faj cov ntsiab lus ntawm cov carburizing tus neeg saib xyuas, nws tus nqi indirectly sawv cev rau qhov zoo ntawm cov khoom, thiab cov tshauv thiab volatile cov ntsiab lus sawv cev rau cov ntsiab lus ntawm impurities nyob rau hauv cov thee carburizing tus neeg saib xyuas siv nyob rau hauv steelmaking, yog li nws yog tsim nyog los xaiv cov thee carburizing tus neeg saib xyuas nrog siab ruaj carbon cov ntsiab lus, tsawg tshauv thiab volatile cov ntsiab lus.
3. Cov ntsiab lus nitrogen
Nitrogen ntsiab lus tseem yog ib qho tseem ceeb qhia los ntsuas qhov zoo ntawm steelmaking thee carburizer, thaum cov nitrogen cov ntsiab lus ntawm thee carburizer siab, cov nitrogen cov ntsiab lus nyob rau hauv cov kua hlau yog nce, cov ntau yaj nitrogen yuav ua rau kom lub stability ntawm carbide, txhawb kev tsim ntawm D-hom graphite, yog li txhim kho cov khoom siv hlau, yog li koj tuaj yeem xaiv cov pa roj carbon monoxide nrog cov ntsiab lus nitrogen ntau dua hauv kev tsim steel.
Hauv cov ntsiab lus, nws tuaj yeem pom tias qhov ntsuas ntawm cov ntsiab lus ntawm leej faj, cov ntsiab lus ruaj khov, cov ntsiab lus tshauv, cov ntsiab lus tsis hloov pauv thiab cov ntsiab lus nitrogen yog siv los ntsuas qhov zoo ntawm cov thee carburizer siv hauv steelmaking, thiab cov ntsiab lus ntawm nitrogen thiab sulfur muaj ntau dua. cuam tshuam.
