Description
В составе флюса могут присутствовать КгО, , МпО, TiOs, Р2О5 в сумме до 5%. Отношение суммы CaF2 + CaO+MgO + K20 к SiOa составл ет 1,5-3,0.CrO, MpO, TiOs, P2O5 in the amount of up to 5% may be present in the composition of the flux. The ratio of the sum of CaF2 + CaO + MgO + K20 to SiOa is 1.5-3.0.
Расход эвтектической смеси 3,3-10 кг/т металлической садки, предпочтительно 3,3-5,0 кг/т металлической садки, соответственно 3,8-5,5 кг/т годной стали.The flow rate of the eutectic mixture is 3.3–10 kg / t of metal cages, preferably 3.3–5.0 kg / t of metal cages, respectively 3.8– 5.5 kg / t of usable steel.
Присадка флюса производитс , как правило , вслед за присадкой извести в период продувки плавки. В завалку присадка флюса не рекомендуетс . Известь в количестве 55- 70% присаживаетс в завалку (налом), остальна часть - по прошествии 10-30% периода продувки плавки. В этот же период присаживаетс флюс. Вторично флюс присаживаетс по прошествии 75-.90% периода продувки плавки.The flux additive is usually produced after the lime additive during the smelt purge period. Flux additive is not recommended for filling. Lime in the amount of 55-70% is squatted in the filling (bulk), the rest - after 10-30% of the melt-blowing period. In the same period, the flux is set. Once again, the flux sits down after 75- .90% of the melt purge period.
