Khoom piav qhia
Lub sub nkag nozzle yog ib qho tseem ceeb ntawm kev txuas cov tundish thiab crystallizer. Nws yog hu ua choke point ntawm nruam casting. Nws plays lub luag haujlwm txuas thiab yog ib feem tseem ceeb ntawm cov txheej txheem steel smelting. Lub qhov hluav taws xob ntawm subentry nozzles raus hauv cov hlau molten nyob rau hauv crystallizer, uas tiv thaiv oxidation theem nrab ntawm cov hlau molten, tswj cov ndlwg tus nqi ntawm cov hlau molten thaum nws nkag mus rau hauv lub crystallizer, yog conducive rau lub floating ntawm inclusions nyob rau hauv lub molten hlau, thiab tuaj yeem tiv thaiv kom tsis txhob muaj kev cuam tshuam. Qhov tshwm sim ntawm slag phenomenon, thiab lwm yam., xyuas kom ruaj khov ntawm cov txheej txheem nruam casting.
