Tub ntxhais hlau yog cov khoom sib xyaw ua los ntawm ntau yam khoom ntxiv (deoxidizers, desulfurizers, modifiers, alloys, thiab lwm yam) crushed rau ib qho me me thiab tom qab ntawd ua rau hauv cov khoom sib xyaw ntawm txhua qhov ntev uas siv cov khoom txias txias uas tsis muaj carbon steel sawb.
Nws tuaj yeem ua kom huv hauv daim ntawv ntawm kev sib koom ua ke, txhim kho cov castability ntawm steel, txhim kho kev siv steel kev ua tau zoo, ua kom cov hlau tawm los, txo cov alloy noj, txo tus nqi ntawm steelmaking, thiab ua tiav cov txiaj ntsig tseem ceeb.
Cov txheej txheem indexes ntawm cored hlau yog raws li nram no:
1, ntxiv rau calcium kev kho mob ntawm cov kua hlau, steel cov tshuaj tiv thaiv kev ruaj ntseg, kom tsis txhob oxidation theem nrab, inclusions floating ceev, purification ntawm kua steel nyhuv yog zoo.
2, Txaus siab rau kev nplua-tuning tswj ntawm steel muaj pes tsawg leeg.
3, alloy yield tau zoo heev.
4, Kev pub hlau tuaj yeem zam tsis txhob nqa roj rau hauv cov hlau.
5, Muaj zog adaptability thiab ntau yam ntawm daim ntawv thov.
6, Cov kab noj khoom noj yog ua los ntawm cov khoom siv, yooj yim los tswj, ruaj khov, tsis muaj kuab paug rau ib puag ncig.
