E faapefea ona filifili carburizer?

2345_image_file_copy_15

E tusa ai ma auala eseese liusuavai, ituaiga ogaumu ma le tele o le ogaumu liusuavai, e taua foi le filifilia o le carburizer talafeagai tele, lea e mafai ona faaleleia lelei le fua faatatau absorption ma absorption fua faatatau o le vai uʻamea i carburizer, aloese mai le oxidation ma mu gau o carburizer mafua mai. e ala i le la'ititi la'ititi.

O lona tele vaega e sili ona lelei: 100kg ogaumu e itiiti ifo i le 10mm, 500kg ogaumu e itiiti ifo nai lo 15mm, 1.5 tone ogaumu e itiiti ifo nai lo 20mm, 20 ton ogaumu e itiiti ifo i le 30mm. Fa'aliliuga fa'asuavai, u'amea maualuga maualuga, le fa'aogaina o le fa'aitiitia o mea leaga i totonu o le vaila'au carbon. O le manaʻoga o le carburizer mo le pito i luga-blown (rotary) converter steelmaking o le maualuga tumau carbon, maualalo mea i totonu o le efuefu, volatilization, sulfur, phosphorus, nitrogen ma isi mea leaga, ma mago, mama, feololo le tele o vaega.Its tumau carbon C≥96% , volatiles ≤1.0%, S≤0.5%, susu ≤0.5%, lapopoa vaega i totonu 1-5mm. Afai e lelei tele le lapopo'a, o le a faigofie ona mu. Afai e mafiafia tele le lapopoa, o le a opeopea i luga o le uʻamea uʻamea ma e le faigofie ona mitiia e le uamea uʻamea. Ole lapopoa o le ogaumu faʻapipiʻi ole 0.2-6mm, o loʻo i ai le tele o le uʻamea ma isi uʻamea ferrous o le 1.4-9.5mm, maualuga le carbon steel e manaʻomia ai le maualalo o le nitrogen, ma le lapopoa o le 0.5-5mm, ma isi. Faʻamasinoga ma filifiliga maʻoti. e tatau ona faia e tusa ai ma le ituaiga o ogaumu smelting workpiece ma isi auiliiliga.
