Stable production of 3200m3 blast furnace in Han Steel
Blast furnace should be based on the principles of safety,high and stable production and low cost.Temper-ature discharge is the basis of furnace running and low cost.The trend management of furnace temperature can sta-bilize the furnace temperature,avoid the fluctuation of furnace temperature and ensure the active furnace cylinder.Four classes of uniform stable operation and run to stabilize the batch and gas flow,the"platform+funnel"fabric is based on the depth of the funnel,so that the gas and ore fully contact to improve the gas utilization rate.It is nec-essary to calculate the coke load in advance of blast furnace shutdown,and reasonable shutdown material plays an important role in the stability of the furnace temperature,which can avoid the phenomenon of overheating or cooling of the furnace temperature.Quality of coke,sinter,ore and pellets are very important guarantee for the stable run-ning of the blast furnace,and a number of measures have been taken to stabilize the ratio of ore at about 20％,re-ducing the cost of ironmaking.
