Based on established a model for changing of MnO content
it was obtained that with increasing apparent rate constant k
flux-steel interfacial area and reacting time
the MnO content in flux increased. The initial (MnO) and initial [Mn] influenced MnO content in flux. The test results showed that during steel 16Mn 4)300 mm billet concasting
the initial MnO content in flux was 1. 5%
after casting for 30 min it increased to 2. 2% ; and during steel Q235 slab casting
as initial (MnO) in flux increased from 0% to 2. 51%
the melting temperature of flux decreased from 1 069 Y to 1 063 ℃
of which the viscosity at 1 300 ℃ decreased from 0. 165 Pa
