No5 blast furnace at Ironmaking Plant
Jiyuan Steel has been analyzed
and combined with real production data of furnace the calculation on equilibrium distribution of zinc is carried out. Results show that zinc load of No5 blast furnace is 625 g/t
in furnace charging
most zinc load is from sinter ore its percentage is up to 72. 22%
next zinc load is from pellet ore it can reach to 24. 13% ; in output items the most amount of zinc is in gas ash which makes up 96. 14% of the total output value. The corresponding measures to control zinc including selecting of charging
optimizing blast furnace operation scheduling and dust de-zincing etc. are presented.
