It is outlet air windband on the lower, windband inside Z-type ventilation duct and burner hearth by being connected to.Forced ventilation cooling is carried out with frequency conversion fan,
DCS controls rotation speed of fan and in-furnace temperature is chain, to realize that reduction phase reaction zone is quickly cooled down and in-furnace temperature is accurately controlled
System.It is easy to operate compared with traditional natural divulges information shaft furnace, it is efficient, not frequently switch on air port manually, reduction can be improved
Stage charging rate shortens the production cycle, reduces power consumption, improves product quality.
The utility model has the beneficial effects that：
1, by the way that three independent windbands are arranged in shaft furnace shell outer wall, two, top is air inlet windband, is on the lower
Outlet air windband realizes that reduction phase air quantity, which is adjusted, to be automated with the chain realization of temperature, improves labor efficiency, and production exercise is significantly mitigated
Make the labor intensity of personnel；
2, when temperature controls rapid more accurate feedback, local overheating, can cool down rapidly；
3, it effectively reduces and stops to expect that phenomenon, reducing material speed can carry supreme at this stage 40% caused by overtemperature, shorten the recovery time
24h；
4, the waste heat recovery in titanium sponge reduction stage is realized.
