Yuav ua li cas Indian kev tsim kho steel tuam txhab txo cov khoom lag luam tsis ruaj khov ntawm vanadium alloy additives?

 

Qhov kev pheej hmoo tseem ceeb tsis yog tsuas yog muaj, tab sismetallurgical instability tshwm sim los ntawm inconsistent mov zoo, uas ua rau:

Tawm lub zog sib txawv ntawm cov cua sov (± 20-60 MPa)

Kev rov qab tsis ruaj khov ntawm vanadium hauv EAF txoj kev (85-96%)

Rebar ductility inconsistency nyob rau hauv cov qauv kev tsim kho (IS 1786 ua raws li kev pheej hmoo)

Nce alloy noj nqi ib tuj steel

Txhawm rau txo cov kev pheej hmoo no, Indian steelmakers tau hloov pauv los ntawm ib qho - qhov kev vam khom raumulti- txheej txheej hlau ruaj ntseg tshuab sib txuas cov khoom lag luam buffering, dual qhov chaw, thiab kev nruj nruj.
