N cov ntsiab lus hauv kev tshuaj ntsuam smelting yuav tsum tsis pub tshaj 0.012%. c Yog hais tias cov tshuaj muaj pes tsawg leeg qhia tau hais tias qhov tsawg kawg nkaus txhuas cov ntsiab lus ntawm 0.020% thiab qhov tsawg kawg nkaus Al / N piv ntawm 2: 1, los yog yog hais tias muaj lwm yam txaus nitrogen-binding ntsiab, cov saum toj no siab tshaj nitrogen cov ntsiab lus txwv tsis pub siv. Nitrogen khi cov ntsiab lus yuav tsum raug sau tseg hauv cov ntaub ntawv tshuaj xyuas.
